Abstract
The utility model discloses a rolling pulverizer, and particularly relates to the rolling pulverizer which is suitable for ore particles. The pulverizer is formed by connecting a rack, a motor, a transmission, a belt transmission mechanism, a transmission shaft, a powder box, a solid disc, a rotary disc, a feeder, a discharge port and a limiter, wherein the fixed disc is fixed on the rack; the inner side face of the disc is provided with a straight groove in a part opposite to the feeder; the rotary disc is fixedly connected with the transmission shaft; the inner side face of the disc is provided with an annular groove which is concentric with the transmission shaft; the lower end of the straight groove extends to the annular groove; the end of the transmission shaft is provided with the limiter which is in threaded connection with the rotary disc. The rolling pulverizer has the advantages of simple, light and compact structure, capability of effectively saving the energy, high crushing efficiency and low equipment maintenance cost.
Description
Technical field
The utility model belongs to subparticle processing machinery equipment, is specifically related to a kind of roll extrusion flour mill of roll extrusion grinding machine, particularly a kind of applicable ore particles.
Background technology
In grain processing, cement manufacture and mine industry, often raw material need to be crushed to Powdered.The material of 1 mm～40 mm is being added to man-hour, and the equipment that prior art adopts has vibromill, ball milling, roller mill etc., the principle of these equipment is, in cylindrical shell rotation or vibration processes, abrasive body (ball, rod etc.) in cylinder produces and impacts and/or abrasive action material, makes crushing material.Abrasive body is to be packed in cylindrical shell in loose mode, and when tiny material particles is impacted or ground, the invalid impact rate of loose abrasive body is higher, need to expend plenty of time and energy and just can make material be crushed to subparticle.And cylinder lining plate is easy to wear, raw meal particle size distributes wayward, need to repeatedly grind and could reach desired particle size completely.In production process, noise is larger, and equipment maintenance cost is higher.In order to improve crushing efficiency, reduce equipment maintenance cost, developing a kind of roll extrusion flour mill is the key point addressing this problem.
Summary of the invention
The purpose of this utility model is to provide a kind of roll extrusion flour mill, efficient, energy-conservation flour mill, have simple in structure, light compactness, the advantage such as crushing efficiency is high, and equipment maintenance cost is low, easy and simple to handle.
The purpose of this utility model is that this flour mill of realizing is like this connected to form by frame, motor, speed changer, belt gear, power transmission shaft, powder casing, solid disk, rolling disc, feeder, discharging opening and stop, fixed disk is fixed in frame, and the medial surface of dish is provided with straight groove over against feeder place; Rolling disc is fixedly connected with power transmission shaft, and the medial surface of dish is provided with the annular groove concentric with power transmission shaft, and the lower end of straight groove extends to annular groove; The stop that the setting of transmission axle head and rolling disc are threaded connection.
Annular groove cross section on described rolling disc is trapezoidal, and more than annular groove You Er road, the straight groove lower end of fixed disk extends in annular groove always.
Described feeder be shaped as infundibulate, its outlet is provided with the deflector chute identical with the straight groove cross section shape of fixed disk, and straight groove docks with deflector chute.
According to particle shattering, in fine grained crushing process, positive pressure can make granule interior along being subject to force direction to produce structural dislocation and slippage, thereby produces a kind of and tension slide surface quadrature, makes particle fracture.The roll extrusion of technical solutions of the utility model is best modes of realizing positive pressure.Rolling disc is fast rotational under the drive of motor, material enters the gap between fixed disk and rolling disc by charging aperture, and material is subject to two pressure and frictional force between dish, is broken into Powdered, the material that granularity is qualified moves to edge under the effect of frictional force, by discharging opening, is fallen.By regulating the rotating speed of motor and the position of stop, just can fragmentation go out varigrained material.Interaction by two mills carrys out roll extrusion material, can improve crushing efficiency, reduces maintenance cost, has reduced the noise while producing, and the utility model is simple in structure, and light compactness is energy-efficient.
Accompanying drawing explanation
Fig. 1 is overall structure of the present utility model and working state schematic representation;
The cooperation schematic diagram of Fig. 2 fixed disk and rolling disc;
In figure: 1-frame, 2-motor, 3-speed changer, 4-belt gear, 5-turning cylinder, 6-powder casing, 7-solid disk, 8-rolling disc, 9-feeder, 10-discharging opening, 11-stop, straight groove-12, annular groove-13.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but never in any form the utility model is limited, any conversion or the replacement based on the utility model training centre, done, all belong to protection domain of the present utility model.
As shown in Figure 1, 2, the utility model comprises frame 1, motor 2, speed changer 3, belt gear 4, turning cylinder 5, powder casing 6, solid disk 7, rolling disc 8, feeder 9, discharging opening 10, stop 11.Described motor 2 is mounted on the below of frame 1, speed changer is connected with motor 2, one end of power transmission shaft 5 is connected with the output of speed changer 3 by belt gear 4, power transmission shaft 5 other ends are connected with rolling disc 8, fixed disk 7 is installed in powder casing 6 and is fixed in frame 1 simultaneously, powder casing 6 tops are charging aperture, below is discharging opening 10, feeder 9 be shaped as infundibulate, its outlet is provided with the deflector chute identical with straight groove 12 shape of cross sections of fixed disk 7, and straight groove 12 is docking together with deflector chute.The medial surface of solid disk 7 is provided with straight groove 12 over against the deflector chute place of feeder, the medial surface of rolling disc 8 is provided with the annular groove 13 concentric with power transmission shaft 5, the lower end of straight groove 12 extends to annular groove 13, and the end of power transmission shaft 5 arranges the stop 11 being threaded connection with rolling disc 8.
