Abstract
The utility model relates to a grinding and pulverizing device of a disk type grinding mill, particularly to the improvement of structures of a single-stage mill for producing modified bitumen, etc. The utility model mainly solves the technical problems that in the prior art, mills can not extend the milling paths, have more energy waste and long working periods, etc. The utility model comprises a milling body (1), wherein a feeding inlet (1-1) and a discharging outlet (1-2) are arranged on the milling body, a movable milling disk (2) and a static milling disk (3) which are matched are arranged in the milling body, the milling body is connected with a bearing seat (5) by a connector (4), and a driving shaft penetrates into the bearing seat and is connected and matched with the movable milling disk (2). The utility model is characterized in that the bottom of a milling groove of the movable milling disk (2) on the milling body (1) is composed of more than two concave pits (2-1); the concave pits are connected together; the rotary radiuses of the bottom surfaces of the concave pits are reduced in a step type.
Description
Technical field
The utility model relates to pulverizing of a kind of disc type grinding mill and reducing mechanism, especially relates to a kind of to producing the isostructural improvement of Single-stage mill of modified pitch.
Background technology
At present, the domestic and international grinding machine of manufacturing, the dynamic and static mill of critical piece all has only a pair to be composed of, and promptly the work period can only be ground one time, and actual grinding-material need just can reach fineness requirement by three to four times.For reaching fineness requirement, adopt repeatedly usually now, the circulation multipass grinds.So just increased production cost.Chinese patent discloses a kind of modified pitch high speed shear homogenizing grinding machine (notification number: CN2620585Y), it includes the mill body of feed pipe and discharging opening, place in the mill body, the corresponding matching face is the movable grinding disc and the static cutting disk of taper seat, on static cutting disk and movable grinding disc, be respectively arranged with the corresponding mutually cutter tooth in position, cutter tooth is arranged at respectively on static cutting disk and the movable grinding disc, the corase grind tooth that the position is corresponding mutually, semi-finishing grinding tooth, finishing grinding tooth and superfine grinding tooth, corase grind tooth and semi-finishing grinding tooth on static cutting disk and the movable grinding disc, semi-finishing grinding tooth and finishing grinding tooth, it is corresponding mutually to be formed with the position between finishing grinding tooth and the superfine grinding tooth, 3 annular escapes that height differs.But the grinding machine of this structure can't form repeatedly and grind, and repeatedly grinds as need, also will use many grinding machines, and energy waste is bigger, and the work period is longer.
Summary of the invention
The purpose of this utility model provides a kind of Single-stage mill, and it mainly is to solve the existing in prior technology grinding machine can't prolong abrasion path, and energy waste is bigger, the technical problem that the work period is long etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Single-stage mill of the present utility model, comprise the mill body, the mill body is provided with charging aperture, discharging opening, mill body inside is provided with movable grinding disc and the static cutting disk that matches, the mill body is connected with bearing block by connector, and bearing block inside is installed with driving shaft, and driving shaft is connected cooperation with movable grinding disc, it is characterized in that on the described mill body movable grinding disc slot grinding bottom by two and more than the pits that link together form, and the radius of gyration of pit bottom surface is notch cuttype and reduces.Movable grinding disc slot grinding bottom is made up of two pits that link together more than reaching, and can make material under the centrifugal action that movable grinding disc rotates at a high speed, and the curvilinear motion from rectilinear motion thickens can increase the grinding probability.
As preferably, described pit is for trapezoidal.The trapezoidal material of being convenient to that falls transports in movable grinding disc slot grinding bottom.
As preferably, the described oblique angle that falls trapezoidal pit inclined-plane is 3 °≤α≤5 °.Oblique angle the best can be made as 5 °.
Therefore, the utlity model has grinding machine and can prolong abrasion path, energy resource consumption economizes, and cost is low, and attended operation is simple and clear, and the work period is short, efficient height, characteristics such as novel and reasonable structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 3 is a kind of structural representations of movable grinding disc;
Accompanying drawing 4 is bowl configurations schematic diagrames of movable grinding disc;
Accompanying drawing 5 is a kind of structural representations of static cutting disk.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the Single-stage mill that this is routine, as Fig. 1, Fig. 2, a mill body 1 is arranged, the mill body is provided with charging aperture 1-1, discharging opening 1-2, as Fig. 3, Fig. 5, mill body inside is provided with the movable grinding disc 2 and static cutting disk 3 that matches, and the mill body is connected with bearing block 5 by bolt 4, bearing block inside is installed with driving shaft, and driving shaft is connected cooperation with movable grinding disc 2.As Fig. 3, Fig. 4, the slot grinding bottom of movable grinding disc 2 is made up of two trapezoidal pit 2-1 that fall that link together, and the radius of gyration of pit bottom surface is notch cuttype and reduces, and promptly the slot grinding bottom is made up of plane, inclined-plane, plane, inclined-plane, plane, inclined-plane, plane successively.Falling the oblique angle on trapezoidal pit 2-1 inclined-plane is 5 °.
During use, in the middle of Single-stage mill, penetrate driving shaft, machine.Mixed pitch is fed the charging aperture 1-1 that grinds body 1, and movable grinding disc 2 rotates, and matches with static cutting disk 3 and grinds bulk pitch.Because movable grinding disc 2 slot grindings bottom is made up of two pit 2-1 that link together, and can make pitch under the centrifugal action that mill rotates at a high speed, becomes complicated curvilinear motion from rectilinear motion, grinding efficiency is than higher.After pitch came out from the discharging opening 1-2 that grinds body, grinding was finished.
Claims (3)
1. Single-stage mill, comprise mill body (1), the mill body is provided with charging aperture (1-1), discharging (1-2), mill body inside is provided with the movable grinding disc (2) and static cutting disk (3) that matches, the mill body is connected with bearing block (5) by connector (4), bearing block inside is installed with driving shaft, driving shaft is connected cooperation with movable grinding disc (2), it is characterized in that on the described mill body (1) movable grinding disc (2) slot grinding bottom by two and more than the pits (2-1) that link together form, and the radius of gyration of pit bottom surface is notch cuttype and reduces.
2. Single-stage mill according to claim 1 is characterized in that described pit (2-1) is for trapezoidal.
3. Single-stage mill according to claim 1 and 2 is characterized in that the described oblique angle that falls trapezoidal pit (2-1) inclined-plane is 3 °≤α≤5 °.
