Fig. 2 is the sectional view schematic diagram of mill of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing illustrated embodiment, the present invention is described in detail.
See Fig. 1, Fig. 2, the present invention is made up of movable grinding disc and fixed millstone.1 is fixed millstone, and 2 is fixed millstone rake tooth, and 3 is movable grinding disc thread, and 4 is movable grinding disc.
Feed arrangement produces motive force to sizing material, is constantly pushed in abrasive disk space by sizing material, and first sizing material enters large region, gap from large end; This district adopts wider teeth groove and dark tooth, tentatively pulverizes sizing material, reduces the size of sizing material; Then enter the region that gap is little, this district adopts narrower teeth groove and shallow tooth, further pulverizes, reach satisfied crushing effect to sizing material.
The size of the cone angle of movable grinding disc, has considerable influence for energy consumption and rubber powder fineness.Therefore the adjustable range of cone angle is 35 ° ~ 55 °.
The cross section of mill face of the present invention crushing tooth is triangle (addendum width is zero).The design of this crushing tooth can make sizing material reach maximum positive voltage power, and then obtains maximum useful work.
Disc surface pulverize the number of teeth number be decide according to pulverizing the degree of grinding that the granularity of sizing material, character and requirement reach.If the particle of sizing material is comparatively large, then adopt the less number of teeth and darker teeth groove; The particle of sizing material is less, then adopt the more number of teeth and more shallow teeth groove.Here adopt gradual change type spiral groove depth.The groove depth of movable grinding disc surface thread is 3 ~ 0mm by large excursion of holding small end.
Smashing fineness at least can regulate by a kind of method, and it comprises: the adjustment of abrasive disk space size; The adjustment of movable grinding disc rotating speed; The change that movable grinding disc turns to; The change (comprising the change of tooth top width, tooth depth, tooth angle) of crushing tooth profile of tooth.
In the mill pulverizer course of work, mill produces two kinds of effects to scrap rubber, and one is that the High Rotation Speed of mill produces centrifugal force to scrap rubber, and scrap rubber is moved from inside to outside along mill; One is that scrap rubber is in the mechanical crushing effect by being subject to during abrasive disk space.
The pulverization of pulverizer mainly relies on the High Rotation Speed of movable grinding disc, creates huge centrifugal force, because this active force constantly throws to the flank of tooth the sizing material in teeth groove.The sizing material of pulverizer enters disintegrating area from the center of mill, and under the pivotal mill of high speed drives, sizing material moves towards circumference from center along spiral involute.Like this, sizing material is owing to being subject to centrifugal force and force of periphery synergy, and sizing material has the trend of radial motion, has again the trend moved in a circle, and because rotating disk is to the high speed relative motion of price fixing or two mills, sizing material also just rises continually and falls between tooth top and teeth groove.In this motion process, sizing material stands the effects such as centrifugal force, twisting resistance, shearing force, pressure, and result makes sizing material be pulverized.
