Abstract

The utility model relates to a crusher, aiming to overcome the defects of small production quantity, multiple powders in the products, inhomogeneous granularity, large power consumption, etc. existing in the present crushing equipment. The crusher is mainly composed of a machine frame, a working chamber casing of a feed hopper and a discharge port fixed on the machine frame, an electromotor, etc. Two rollers rotating respectively and reversely driven by the electromotor outside the working chamber casing are arranged in the working chamber casing. The utility model has the advantages of big production quantity, low preparing cost, uniform granularity, high rate of finished products, easy manufacture and easy use. The utility model can be widely suitable for crushing materials, such as coal, coke, ore, trona, pottery clay, etc.

Description

A kind of breaker

The utility model relates to a kind of breaker, specifically is a kind ofly to be fixed and bulk materials is squeezed the processing disintegrating apparatus that is broken into required fritter by the extruding of two rollers of backwards rotation by relative position.

At present, industrial and mining enterprises mainly contain two kinds of rotation hammer crushing mechanism and the board-like crushing mechanisms of crocodile for bulk materials being broken into equipment that fritter adopts.The former relies on the rotation of the hammer in the working chamber with charging aperture and discharging opening to smash material, and granularity is little, the finished product granularity is inhomogeneous, powder is many so use this equipment not only to feed intake, and power consumption is big, processing efficient is low, output is little.The latter relies on the extruding of the relatively-stationary two clamping plates of the side position material of crushing, though the accommodation to the granularity that feeds intake increases to some extent, have shortcomings such as the processing efficient of rotating the hammer crushing mechanism is low, the finished product granularity is inhomogeneous, output is little equally.

The purpose of this utility model provides a kind of pulley type breaker.Use this device granularity that not only feeds intake big, and processing cost is low, yield rate is high and product granularity is even.

Concrete technical scheme of the present utility model is: this device mainly is made up of frame, the working chamber casing that is fixed on band hopper on the frame and discharging opening and motor etc.Wherein, two rollers that connect with motor reverse drive outside the working chamber casing are respectively arranged in the working chamber casing, and these two rollers respectively by the roll bearing seat secured in parallel on frame.

In order to prolong the service life of roller, and increase the frictional force of roller surface, protrusions such as roller bar, roller tooth, roller sour jujube can be set at roller surface.

In order to make the distance between two rollers adjustable, roll bearing seat can be passed through hydraulic mechanism, also can be by the spiral guiding mechanism, be fixed on the frame with adjustment plate of different eye distances etc.

The utility model has the advantages that: during use, after putting in the working chamber from hopper material, granularity sinks could be discharged from discharging opening by two roller gaps behind the two roller attrition crushings of counter-rotating because of gravity greater than the material of two roll gaps, and the little material of granularity does not live, is not extruded and promptly discharges from discharging opening by two roller gaps because of clamping between two rollers, as seen its broken workflow letter refining, rationally, thus cause that powder is few in the product, wastage of material is few, yield rate is high and finished product epigranular, the granularity that feeds intake big; Because of the utility model principle, simple in structure, required supporting power is little again, so low, the broken working ability of its processing cost is strong, output is big.Can be widely used in the fragmentation processing of materials such as coal, coke, ore, trona, potter's clay.

Fig. 1 is a principle schematic of the present utility model;

Fig. 2 is an embodiment schematic diagram of the present utility model;

Fig. 3 is an embodiment schematic diagram of roller.

The utility model is described in further detail below in conjunction with accompanying drawing:

As shown in Figure 1 and Figure 2: this device mainly by frame (1), be fixed on band hopper (3) on the frame (1) and the working chamber casing (4) and the motor (5) of discharging opening (6) formed.Two rollers (2) that connect with two motors (5) reverse drive outside the working chamber casing (4) are respectively arranged in working chamber casing (4), these two rollers (2) respectively by roll bearing seat (7) secured in parallel on frame (1).During work, material is put in the working chamber casing (4) by hopper (3), its granularity is not extruded promptly and discharges from discharging opening (6) by two roller gaps less than distance between two rollers (2); And its granularity could be discharged from discharging opening by two roller gaps behind two rollers (2) attrition crushing of backwards rotation greater than distance between two rollers.As seen, install through this that finished product granularity is even, powder is few, thereby wastage of material is few, yield rate is high.Little because of simple, the supporting power of this apparatus structure again, can manufacture the various models that vary in size, so reached the purpose that the granularity that feeds intake is big, output is big, processing cost is low easily.

In order to use same equipment to process the different product of granule size requirement easily, the roll bearing seat of this device (7) can be fixed on frame (1) by the adjustment plate (8) with different eye distances and go up (as shown in Figure 2).When the little product of needs processing particle size after cracking, adjust roll bearing seat (7) with the position on the adjustment plate (8) of different eye distances to a side, the distance between two rollers (2) is reduced; When the big product of needs processing particle size after cracking, adjust roll bearing seat (7) with the position on the adjustment plate (8) of different eye distances to opposite side, the distance between two rollers (2) is increased.As seen, this device is not only suitable to process the product that granularity requirements varies in size, and use is quite convenient.Certainly, its roll bearing seat also can adopt other modes such as spiral guiding mechanism, hydraulic mechanism to fix.

In order to increase the frictional force of roller surface, (as shown in Figure 3 :) can be on roller surface protrusions such as welding rolls bar (9), roller tooth (10), roller sour jujube at the same time or separately, when making this device busy easier with bulk materials be brought between two rollers squeeze broken, and the unlikely powder that is pressed into, make product granularity more even, also make more wear-resistant, the long service life of roller simultaneously.

In addition, in roller, several stiffeners can also be set the service life for being fit to process harder material and prolonging roller, be extruded distortion in the course of the work to prevent roller.
