Description

本発明は、伝熱性能や混練性能に優れた二軸フィーダ並びにこれを用いたシーティング装置及び混練システムに関する。   The present invention relates to a biaxial feeder excellent in heat transfer performance and kneading performance, and a sheeting apparatus and a kneading system using the same.

混練機から排出されたゴム又は樹脂を、ケーシング内に二本のテーパスクリューを配設してなる二軸フィーダにより押出し、次工程（シート化、成形など）に供給する押出装置が、特許文献１や特許文献２で開示されている。   An extrusion apparatus in which rubber or resin discharged from a kneader is extruded by a biaxial feeder in which two taper screws are arranged in a casing and is supplied to the next process (sheeting, molding, etc.) is disclosed in Patent Document 1. And Patent Document 2.

また、上記二軸フィーダを用いた混練システムとして、例えば図９に示すようなものが知られている。   Further, as a kneading system using the above biaxial feeder, for example, a system shown in FIG. 9 is known.

これによれば、先ず、原料ゴムと配合剤がマスターバッチ用混練機１００でマスター混練され、ここから排出されたマスターバッチゴムは、アンダーミキサ１０１Ａによってシート化され、外部冷却装置１０２Ａによって冷却された後、再びマスターバッチ用混練機１００に戻されてリミル混練される。このリミル（再練り）工程は１回又は複数回、行われる。その後、マスターバッチゴムは加硫剤とともにファイナル用混練機１０３に投入されてファイナル混練される。ここから排出されたマスターバッチゴムは、アンダーミキサ１０１Ｂによってシート化され、外部冷却装置１０２Ｂによって冷却された後、成形／加硫工程に移行するようになっている。   According to this, first, the raw rubber and the compounding agent are master-kneaded by the master batch kneader 100, and the master batch rubber discharged therefrom is formed into a sheet by the undermixer 101A and cooled by the external cooling device 102A. Then, it is returned to the master batch kneader 100 again and remill kneaded. This remill (re-kneading) step is performed once or a plurality of times. Thereafter, the master batch rubber is put into a final kneader 103 together with a vulcanizing agent and final kneaded. The master batch rubber discharged from here is formed into a sheet by the undermixer 101B, cooled by the external cooling device 102B, and then transferred to the molding / vulcanizing step.

しかしながら、従来の二軸フィーダにあっては、ケーシングが冷却水供給用のジャケット構造を有すると共にテーパスクリューにおけるスクリュー軸の内部に冷却水の循環流路を設けるなどして冷却機能を奏しているが、未だ冷却効果が不十分であった。   However, in the conventional biaxial feeder, the casing has a jacket structure for supplying cooling water and has a cooling function by providing a cooling water circulation passage inside the screw shaft of the taper screw. The cooling effect was still insufficient.

また、二軸フィーダはテーパスクリューによる押出能力のみであり、混練機能は有していなかった。   Moreover, the biaxial feeder was only the extrusion capability by a taper screw, and did not have a kneading function.

また、二軸フィーダは冷却効果が不十分でかつ混練機能を有していないため、次工程においてさらに混練（リミルやファイナル混練）を行う必要がある混練システムにおいては、例えばアンダーミキサ２Ａでシート化した後、外部冷却装置３Ａを通じて一旦冷却してから再度混練を行う必要があるなどで、プロセスを簡素化して速やかに次工程に移行することができず、生産性の低下でコストアップを招来しているという問題点もあった。   In addition, since the biaxial feeder has an insufficient cooling effect and does not have a kneading function, in a kneading system that requires further kneading (remilling or final kneading) in the next step, for example, a sheet is formed with an undermixer 2A. After that, it is necessary to cool once through the external cooling device 3A and then knead again, so that it is not possible to simplify the process and quickly move to the next step, resulting in an increase in cost due to a decrease in productivity. There was also a problem of being.

本発明は、上記状況に鑑みてなされたものであり、伝熱能力が高く混練機能を有して混練システムの簡素化が図れる二軸フィーダ並びにこれを用いたシーティング装置及び混練システムを提供することを目的とする。   The present invention has been made in view of the above situation, and provides a biaxial feeder that has a high heat transfer capability and has a kneading function and can simplify the kneading system, and a sheeting device and a kneading system using the biaxial feeder. With the goal.

上記目的を達成するための本発明に係る二軸フィーダは、ケーシング内に二本のテーパスクリューを配設してなる二軸フィーダにおいて、
前記テーパスクリューにおけるスクリュー軸径Ｄ１とスクリュー翼径Ｄ２との比であるＤ１／Ｄ２が、０．３５以上であることを特徴とする。 In order to achieve the above object, a biaxial feeder according to the present invention is a biaxial feeder in which two taper screws are arranged in a casing.
D1 / D2, which is a ratio of the screw shaft diameter D1 and the screw blade diameter D2 in the taper screw, is 0.35 or more.

また、ケーシング内に二本のテーパスクリューを配設してなる二軸フィーダにおいて、
前記ケーシング内に、前記テーパスクリューの周囲に位置して複数のピンを着脱可能に配設したことを特徴とする。 Moreover, in the biaxial feeder formed by arranging two taper screws in the casing,
A plurality of pins are detachably arranged in the casing around the taper screw.

また、前記ピンの内部に熱媒体の循環流路を設けたことを特徴とする。   Further, a heat medium circulation passage is provided inside the pin.

また、前記ケーシングは、熱媒体供給用のジャケット構造を有することを特徴とする。   The casing has a jacket structure for supplying a heat medium.

また、前記テーパスクリューにおけるスクリュー軸の内部に熱媒体の循環流路を設けたことを特徴とする。   The taper screw may be provided with a heat medium circulation passage inside a screw shaft.

上記目的を達成するための本発明に係るシーティング装置は、前述した構成の二軸フィーダの下流にローラヘッドを連設してなることを特徴とする。   In order to achieve the above object, a sheeting apparatus according to the present invention is characterized in that a roller head is provided downstream of a biaxial feeder having the above-described configuration.

上記目的を達成するための本発明に係る混練システムは、マスターバッチ用混練機とファイナル用混練機とを備えた混練システムにおいて、少なくともマスターバッチ用混練機の下流に前述した構成の二軸フィーダを連設したことを特徴とする。   To achieve the above object, the kneading system according to the present invention is a kneading system comprising a masterbatch kneader and a final kneader, wherein at least the biaxial feeder having the above-described configuration is provided downstream of the masterbatch kneader. It is characterized by the fact that it is connected in series.

また、前記混練システムを用いてゴム又はゴム系組成物を混練することを特徴とする。   Further, the rubber or rubber-based composition is kneaded using the kneading system.

本発明に係る二軸フィーダによれば、伝熱能力の向上と押出能力に加えて混練機能が得られる。   According to the biaxial feeder according to the present invention, a kneading function can be obtained in addition to improvement in heat transfer capability and extrusion capability.

本発明に係るシーティング装置によれば、ローラヘッドにおける冷却機構の簡素化と低能力仕様が図れる。   According to the sheeting apparatus of the present invention, the cooling mechanism in the roller head can be simplified and low-capacity specifications can be achieved.

本発明に係る混練システムによれば、外部冷却装置の削減やリミルの回数低減等プロセスを簡素化して速やかに次工程に移行することができ、生産性の向上でコストダウンが図れる。   The kneading system according to the present invention simplifies the process such as reducing the number of external cooling devices and reducing the number of remills, and can quickly move to the next step, thereby improving the productivity and reducing the cost.

以下、本発明に係る二軸フィーダ並びにこれを用いたシーティング装置及び混練システムを実施例により図面を用いて詳細に説明する。   DESCRIPTION OF EMBODIMENTS Hereinafter, a biaxial feeder according to the present invention, a sheeting apparatus and a kneading system using the same will be described in detail with reference to the drawings.

図１は本発明の実施例１を示す二軸フィーダの側面図、図２は実験により得られたスクリュー軸径／スクリュー翼径比と冷却性能（ゴム温度）との関係を示すグラフである。   FIG. 1 is a side view of a biaxial feeder showing Example 1 of the present invention, and FIG. 2 is a graph showing a relationship between a screw shaft diameter / screw blade diameter ratio and cooling performance (rubber temperature) obtained by experiment.

図１に示すように、本二軸フィーダ１は、架台２上に設置された、投入口としてのホッパー３を備えたケーシング４内に、二本の（図面上では一本しか図示されていないが）テーパスクリュー５が配設されてなる。この二本のテーパスクリュー５は、ギヤボックスや減速機からなる動力伝達部６を介して図示しないモータにより、異方向に回転駆動されるようになっている。   As shown in FIG. 1, the biaxial feeder 1 has two (only one is shown in the drawing) in a casing 4 provided on a gantry 2 and provided with a hopper 3 as an input port.

前記ケーシング４は、図示しないが、外部から冷却水（熱媒体）が供給・循環されるジャケット構造を有すると共に、前記テーパスクリュー５におけるスクリュー軸５ａの内部には、外部から冷却水（熱媒体）が供給・循環される図示しない循環流路が形成されている。図中７がテーパスクリュー５における冷却水供給口である。   Although not shown, the casing 4 has a jacket structure in which cooling water (heat medium) is supplied and circulated from the outside, and inside the screw shaft 5a of the taper screw 5, cooling water (heat medium) is externally provided. A circulation channel (not shown) through which is supplied and circulated is formed. In the figure, reference numeral 7 denotes a cooling water supply port in the taper screw 5.

前記二本のテーパスクリュー５において、ゴム又はゴム系組成物である被混練物がホッパー３より投入されるテーパスクリュー５の根元部は、スクリュー翼５ｂとスクリュー軸５ａの軸径が非常に大きく、被混練物に対して噛み込み、噛み砕きの機能が十分に得られる構造になっている一方、テーパスクリュー５の先端部では、スクリュー翼５ｂとスクリュー軸５ａの軸径が根元部に比べて小さく絞り込まれた構造になっている。   In the two taper screws 5, the root portion of the taper screw 5 into which the material to be kneaded, which is rubber or a rubber-based composition, is charged from the hopper 3, has very large shaft diameters of the screw blade 5b and the screw shaft 5a. While it has a structure in which the functions of biting and crushing are sufficiently obtained with respect to the material to be kneaded, the shaft diameter of the screw blade 5b and the screw shaft 5a is narrowed down at the tip of the taper screw 5 as compared with the root portion. It has a structured structure.

そして、本実施例では、前記スクリュー軸５ａの軸径Ｄ１とスクリュー翼５ｂの翼径Ｄ２との比であるＤ１／Ｄ２が、０．３５以上、好ましくは０．５以上に設定されている。   In this embodiment, D1 / D2, which is the ratio of the shaft diameter D1 of the screw shaft 5a and the blade diameter D2 of the screw blade 5b, is set to 0.35 or more, preferably 0.5 or more.

このように構成されるため、前述した二本のテーパスクリュー５の構造により、当該テーパスクリュー５が異方向へ回転することによって、ケーシング４内の被混練物は適度に圧縮されて、図示しないローラヘッド等へ安定して連続供給される。   Due to such a configuration, the material to be kneaded in the casing 4 is appropriately compressed by rotating the taper screw 5 in different directions by the structure of the two taper screws 5 described above, and a roller (not shown) Stable and continuous supply to the head or the like.

また、前述したケーシング４やテーパスクリュー５の冷却水による冷却機構により、ケーシング４内の被混練物は適度に冷却される。   Moreover, the to-be-kneaded material in the casing 4 is cooled moderately by the cooling mechanism by the cooling water of the casing 4 and the taper screw 5 mentioned above.

そして、本実施例では、前記スクリュー軸５ａの軸径Ｄ１とスクリュー翼５ｂの翼径Ｄ２との比であるＤ１／Ｄ２が、０．３５以上、好ましくは０．５以上に設定されているので、二軸フィーダ１内の冷却性能が向上される。   In this embodiment, D1 / D2, which is the ratio of the shaft diameter D1 of the screw shaft 5a and the blade diameter D2 of the screw blade 5b, is set to 0.35 or more, preferably 0.5 or more. The cooling performance in the biaxial feeder 1 is improved.

即ち、前記Ｄ１／Ｄ２の設定により、スクリュー軸５ａとケーシング４との間の被混練物の厚みを伝熱能力の面から適正化でき、冷却水による冷却機構の冷却作用を十分に発揮させられて二軸フィーダ１内の冷却性能が高められることから、図２に示す実験結果でも判るように、冷却時間（被混練物の滞留時間）が短くても温度低下の効果が期待でき、被混練物の材料に左右されない汎用性の高い二軸フィーダ１を提供することができる。   That is, by setting D1 / D2, the thickness of the material to be kneaded between the screw shaft 5a and the casing 4 can be optimized from the aspect of heat transfer capability, and the cooling action of the cooling mechanism by cooling water can be sufficiently exhibited. Since the cooling performance in the biaxial feeder 1 is enhanced, as can be seen from the experimental results shown in FIG. 2, the effect of lowering the temperature can be expected even if the cooling time (retention time of the material to be kneaded) is short. It is possible to provide a highly versatile biaxial feeder 1 that is not affected by the material of the product.

尚、上記実施例において、被混練物がゴム又はゴム系組成物以外の樹脂等の場合、あるいは比較的低温で供給されるゴム又はゴム系組成物であって成形性を高めるため加温する必要があるような際は、熱媒体として温水が用いられる場合もある。   In the above embodiment, when the material to be kneaded is a rubber or a resin other than the rubber-based composition, or a rubber or a rubber-based composition supplied at a relatively low temperature, it is necessary to heat to improve the moldability. In some cases, hot water may be used as a heat medium.

図３は本発明の実施例２を示す二軸フィーダ１の構造説明図である。   FIG. 3 is an explanatory view of the structure of the biaxial feeder 1 showing Embodiment 2 of the present invention.

これは、実施例１におけるケーシング４内に、テーパスクリュー５の周囲に位置して複数のピン１０を着脱可能に配設した例である。その他の構成は、実施例１と同様なので、図１と同一部材には同一符号を付して重複する説明は省略する。尚、本実施例において、特に、実施例１と同様なＤ１／Ｄ２（図１参照）の設定を行わなくても良いが、行ってもよい。   This is an example in which a plurality of pins 10 are detachably disposed in the casing 4 in the first embodiment and positioned around the taper screw 5. Since other configurations are the same as those of the first embodiment, the same members as those in FIG. In the present embodiment, the setting of D1 / D2 (see FIG. 1) similar to that in the first embodiment may not be performed, but may be performed.

前記ピン１０は、ケーシング４にねじ込み又はねじ止め等されて、周方向に所定間隔離間して複数配置されると共に長手方向（スクリュー軸５ａの軸方向）に複数段（図示例では２段）に亙って配置される。勿論、テーパスクリュー５の回転を妨げない位置で、かつ被混練物の押出作用に支障をきたさない本数で配置される。   The pin 10 is screwed or screwed into the casing 4 and arranged in a plurality at a predetermined interval in the circumferential direction and in a plurality of stages (two stages in the illustrated example) in the longitudinal direction (axial direction of the screw shaft 5a). Arranged. Of course, it arrange | positions by the number which does not interfere with the extrusion effect | action of the to-be-kneaded material in the position which does not prevent rotation of the taper screw 5. FIG.

そして、前記ピンの内部には、外部から冷却水（熱媒体）が供給・循環される循環流路１１が形成されている。図中１２ａがその外部冷却水入口で、１２ｂが外部冷却水出口である。   A circulation channel 11 is formed inside the pin, through which cooling water (heat medium) is supplied and circulated from the outside. In the figure, 12a is the external cooling water inlet, and 12b is the external cooling water outlet.

これによれば、ケーシング４やテーパスクリュー５の冷却水による冷却機構に加えて、複数のピン１０の冷却水による冷却機構により、冷却能力が一段とアップし、被混練物を十分冷却することができる。   According to this, in addition to the cooling mechanism by the cooling water of the casing 4 and the taper screw 5, the cooling capability by the cooling water by the cooling water of the plurality of pins 10 is further improved, and the material to be kneaded can be sufficiently cooled. .

また、本実施例では、複数のピン１０の邪魔板効果により、押出能力に加えて混練機能も得られ、汎用性の高い二軸フィーダ１を提供することができる。また、複数のピン１０はケーシング４に対し着脱可能であるため、テーパスクリュー５等の交換時に、脱することで、テーパスクリュー５等を容易に交換することができる。   Further, in this embodiment, the kneading function is obtained in addition to the extrusion ability by the baffle effect of the plurality of pins 10, and the highly versatile biaxial feeder 1 can be provided. Further, since the plurality of pins 10 can be attached to and detached from the casing 4, the taper screw 5 and the like can be easily replaced by removing the tape 10 when the taper screw 5 and the like are replaced.

尚、上記実施例において、被混練物がゴム又はゴム系組成物以外の樹脂等の場合、あるいは比較的低温で供給されるゴム又はゴム系組成物であって成形性を高めるため加温する必要があるような際は、熱媒体として温水が用いられる場合もある。   In the above embodiment, when the material to be kneaded is a rubber or a resin other than the rubber-based composition, or a rubber or a rubber-based composition supplied at a relatively low temperature, it is necessary to heat to improve the moldability. In some cases, hot water may be used as a heat medium.

図４は本発明の実施例３を示すシーティング装置の側面図である。   FIG. 4 is a side view of a sheeting apparatus showing Embodiment 3 of the present invention.

これは、実施例１又は実施例２における二軸フィーダ１の下流にローラヘッド２０を連設してシーティング装置を構成した例である。従って、二軸フィーダ１においては、図１及び図３と同一部材には同一符号を付して重複する説明は省略する。   This is an example in which a sheeting device is configured by connecting a roller head 20 downstream of the biaxial feeder 1 in the first or second embodiment. Therefore, in the biaxial feeder 1, the same members as those in FIGS.

ローラヘッド２０は、ハウジング２１内に上下一対の圧延ロール２２，２３を軸支してなり、これら圧延ロール２２，２３は、図示しない駆動手段により異方向に回転駆動されるようになっている。圧延ロール２２，２３の内部には、外部から冷却水（熱媒体）が供給・循環される図示しない循環流路が形成されている。   The roller head 20 has a pair of upper and lower rolling rolls 22 and 23 supported in a housing 21. The rolling rolls 22 and 23 are driven to rotate in different directions by a driving means (not shown). Inside the rolling rolls 22, 23, a circulation passage (not shown) through which cooling water (heat medium) is supplied and circulated from the outside is formed.

また、ハウジング２１は、ベース２４上に敷設されたレール２５に沿い車輪２６を介して移動可能になっており、二軸フィーダ１に対しローラヘッド２０が必要に応じて接近離反するようになっている。図中２７は、上圧延ロール２２を昇降させるボールねじで、圧延ロール２２，２３間のギャップ（所謂、シート厚さ）を調製し得るようになっている。また、図中２８は、二軸フィーダ１から押し出された被混練物を一時的に蓄える受台で、この受台２８にも外部から冷却水（熱媒体）が供給・循環される図示しない循環流路が形成されている。   The housing 21 is movable along a rail 25 laid on the base 24 via a wheel 26 so that the roller head 20 approaches and separates from the biaxial feeder 1 as necessary. Yes. In the figure, reference numeral 27 denotes a ball screw for raising and lowering the upper rolling roll 22, and a gap (so-called sheet thickness) between the rolling rolls 22 and 23 can be adjusted. In the figure, reference numeral 28 denotes a cradle for temporarily storing the material to be kneaded pushed out from the biaxial feeder 1, and a cooling water (heat medium) is supplied and circulated from the outside to the cradle 28 as well. A flow path is formed.

このように構成されるため、二軸フィーダ１から押し出された被混練物は、受台２８を経て、圧延ロール２２，２３間を通過することで、所定厚さのシートに形成される。   Since it is comprised in this way, the to-be-kneaded material extruded from the biaxial feeder 1 is formed in the sheet | seat of predetermined thickness by passing between the rolling rolls 22 and 23 through the receiving stand 28. FIG.

そして、本実施例では、二軸フィーダ１において前述した高冷却性能により被混練物が十分に冷却されているので、ローラヘッド２０においては、その冷却機構の簡素化や低能力仕様で十分対応することができる。   In this embodiment, since the material to be kneaded is sufficiently cooled by the high cooling performance described above in the biaxial feeder 1, the roller head 20 can be sufficiently handled by the simplification of the cooling mechanism and the low capacity specification. be able to.

尚、上記実施例において、被混練物がゴム又はゴム系組成物以外の樹脂等の場合、あるいは比較的低温で供給されるゴム又はゴム系組成物であって成形性を高めるため加温する必要があるような際は、熱媒体として温水が用いられる場合もある。   In the above embodiment, when the material to be kneaded is a rubber or a resin other than the rubber-based composition, or a rubber or a rubber-based composition supplied at a relatively low temperature, it is necessary to heat to improve the moldability. In some cases, hot water may be used as a heat medium.

図５は本発明の実施例４を示す混練システムの概略構成図である。   FIG. 5 is a schematic configuration diagram of a kneading system showing Example 4 of the present invention.

これは、図９に示した従来の混練システムにおける、マスターバッチ用混練機１００下流のアンダーミキサ１０１Ａに代えて、実施例１又は実施例２における二軸フィーダ１を用いるようにした例である。その他の構成は図９と同様なので、図９と同一部材には同一符号を付して重複する説明は省略する。   This is an example in which the biaxial feeder 1 in Example 1 or Example 2 is used in place of the undermixer 101A downstream of the master batch kneader 100 in the conventional kneading system shown in FIG. Since other configurations are the same as those in FIG. 9, the same members as those in FIG.

これによれば、二軸フィーダ１が前述したように高冷却性能を有することで、外部冷却装置１０２Ａ（図９参照）を介さずに次工程のリミルあるいはファイナル混練に移行でき、１パス混練が可能となる。また、二軸フィーダ１が前述したように混練機能を有することで、リミルの回数低減が図れる。   According to this, since the biaxial feeder 1 has the high cooling performance as described above, it is possible to shift to the remill or final kneading of the next step without using the external cooling device 102A (see FIG. 9), and the one-pass kneading can be performed. It becomes possible. Further, since the biaxial feeder 1 has a kneading function as described above, the number of remills can be reduced.

これらの結果、生産性向上と省力化が図れる。また、外部冷却装置１０２Ａが不要となることで、混練システムの省スペース化及び低コスト化が可能となる。   As a result, productivity can be improved and labor can be saved. Further, since the external cooling device 102A is not necessary, the space saving and cost reduction of the kneading system can be achieved.

尚、上記実施例において、二軸フィーダ１にファイナル用混練機１０３を連設する場合、図６に示すように、二本の接線式ロータ３１や噛合式ロータ３２を備えたバッチ式混練装置３０Ａ，３０Ｂをファイナル用混練機として用いても良く、図７に示すように、一本又は二本のスクリューセット４１を備えた連続式混練装置４０をファイナル用混練機として用いても良い。   In the above embodiment, when the final kneading machine 103 is connected to the biaxial feeder 1, as shown in FIG. 6, a batch kneading apparatus 30A having two tangential rotors 31 and a meshing rotor 32 is provided. 30B may be used as a final kneading machine, and as shown in FIG. 7, a continuous kneading device 40 including one or two screw sets 41 may be used as a final kneading machine.

これは、実施例４における、ファイナル用混練機１０３下流のアンダーミキサ１０１Ｂに代えて、実施例１又は実施例２における二軸フィーダ１を用いるようにした例である。その他の構成は図５と同様なので、図５と同一部材には同一符号を付して重複する説明は省略する。   This is an example in which the biaxial feeder 1 in Example 1 or Example 2 is used instead of the undermixer 101B downstream of the final kneader 103 in Example 4. Since other configurations are the same as those in FIG. 5, the same members as those in FIG.

これによれば、二軸フィーダ１が前述したように高冷却性能を有することで、外部冷却装置１０２Ｂ（図５参照）を介さずに次工程の成形／加硫工程に移行できる。   According to this, since the biaxial feeder 1 has high cooling performance as described above, it is possible to shift to the next molding / vulcanizing step without using the external cooling device 102B (see FIG. 5).

この結果、実施例４に比べてより一層の生産性向上と省力化が図れる。また、外部冷却装置１０２Ｂが不要となることで、混練システムのより一層の省スペース化及び低コスト化が可能となる。   As a result, productivity can be further improved and labor can be saved as compared with the fourth embodiment. Further, since the external cooling device 102B is not required, the space for the kneading system can be further reduced and the cost can be reduced.

尚、上記実施例においても、二軸フィーダ１にファイナル用混練機１０３を連設する場合、図６に示すように、二本の接線式ロータ３１や噛合式ロータ３２を備えたバッチ式混練装置３０Ａ，３０Ｂをファイナル用混練機として用いても良く、図７に示すように、一本又は二本のスクリューセット４１を備えた連続式混練装置４０をファイナル用混練機として用いても良い。   Also in the above-described embodiment, when the final kneader 103 is connected to the biaxial feeder 1, as shown in FIG. 6, a batch-type kneading apparatus provided with two tangential rotors 31 and meshing rotors 32. 30A and 30B may be used as a final kneader, and as shown in FIG. 7, a continuous kneader 40 including one or two screw sets 41 may be used as a final kneader.
