Abstract

The utility model belongs to the technical field of machinery manufacturing of building materials and in particular relates to a multi-roller crusher. The crusher comprises multiple groups of roller crushing units and a machine housing, wherein each roller crushing unit comprises a motor, a speed reducer, a roller barrel and a roller shaft; the motors are connected with the speed reducers; the speed reducers are connected with the roller shafts; the roller barrels are arranged on the roller shafts; the machine housing comprises a base, a bearing block and protective plates; the bearing block and the protective plate are arranged on the base; the two ends of each roller shaft are arranged on the bearing block; the roller barrels are arranged among the protective plates. According to the multi-roller crusher disclosed by the utility model, the roller surfaces of the roller barrels are tooth-shaped, so that materials with complex shapes, including building garbage, shale, coal gangue and the like, can be extruded to be ground; the three or more roller barrels can be used for crushing more materials within unit time in comparison with two roller barrels; the axial length of the roller barrels is greater, and the contact surface between the rollers is larger, so that more materials can be crushed within unit time, and the working efficiency is high.

Description

A kind of multiple roll crusher

Technical field

The utility model belongs to building material machinery manufacturing technology field, is specifically related to a kind of multiple roll crusher.

Background technology

Kibbler roll, by the difference of the roller quantity that adopts, can be divided into single roller, two roller and multiple roll crusher.The frictional force of utilizing roll surface is the material fracture area of nipping, and makes material bear extruding or splitting and be broken, and is applicable to medium-hard material, as the coarse crushings such as ore, rock, in broken or operation in small, broken bits.

At present, the double-roll crusher that brick and tile manufacturing enterprise is generally used will exist deficiency and the defect of the following aspects:

1. common double-roll crusher can only be pulverized some more short grained raw materials, can't enter between two rollers and carry out attrition crushing for larger raw material;

2. for too high raw materials of the more complicated intensity of profile such as those complex building rubbish, shale, gangues, can not fully carry out attrition crushing;

3. operating efficiency is lower, and the axial length of roll surface is shorter, generally only has two rollers, and material quantity that can be broken in the unit interval is less, broken insufficient.

Summary of the invention

The utility model provides a kind of multiple roll crusher, and this disintegrating machine can solve common disintegrating machine can't the larger raw material of fragmentation, the problem such as fully the too high raw material of attrition crushing complex contour, intensity and operating efficiency be lower.

The technical solution of the utility model is as follows:

A kind of multiple roll crusher, is characterized in that, comprises the broken unit of roller and casing; The broken unit of described roller comprises motor, reductor, roller and roll shaft; Described motor is connected with reductor, and reductor is connected with roll shaft, and roller is arranged on roll shaft; Described casing comprises base, and bearing block and backplate, bearing block and backplate all are arranged on base, and the two ends of described roll shaft are arranged on bearing block, and roller is arranged in backplate.

Described multiple roll crusher further designs and is, the broken unit of roller has more than three groups or three groups.

Described multiple roll crusher further design is, the roll surface of roller is profile of tooth, and roller is all at the same level line and be parallel to each other.

Described multiple roll crusher further designs and is, base is the rectangular box structure.

Described multiple roll crusher further designs and is, reductor fixes on the ground by the reductor support.

The beneficial effects of the utility model are as follows:

1. the utility model multiple roll crusher, the roll surface of roller is profile of tooth, can push pulverizing to the raw material of the complex contour types such as building waste, shale, gangue.

2. the utility model multiple roll crusher, roller has more than three or three, and compared to two rollers, material broken in the unit interval is more.

3. the utility model multiple roll crusher, the axial length of roller is longer, and the contact-making surface between roller and roller is larger, and material that can be broken in the unit interval is more, high efficiency.

The accompanying drawing explanation

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model front view.

Fig. 3 is the structural representation of roller.

In figure: the 1-motor; The 2-reductor; The 3-roller; The 4-roll shaft; The 5-base; The 6-bearing block; The 7-backplate; 8-reductor support.

The specific embodiment

As Fig. 1, shown in 2, the utility model multiple roll crusher, the broken unit of roller has three groups, comprises motor 1, reductor 2, roller 3 and roll shaft 4; Motor 1 is connected with reductor 2, and reductor 2 fixes on the ground by reductor support 8, and reductor 2 is connected with roll shaft 4, and roller 3 is arranged on roll shaft 4; Casing comprises base 5, bearing block 6 and backplate 7, and bearing block 6 and backplate 7 all are arranged on base 5, and the two ends of roll shaft 4 are arranged on bearing block 6.

As shown in Figure 3, roller 3 has three, roller 3 is located in backplate 7, the roll surface of roller 3 is profile of tooth, and three rollers 3 are all at the same level line and be parallel to each other, and wherein leftmost roller 3 and rightmost roller 3 all rotate towards centre, one turns clockwise, one is rotated counterclockwise, and middle roller 3 is clockwise, and being rotated counterclockwise can.

When multiple roll crusher is worked, material to be processed is poured into backplate 7 from the disintegrating machine top, material is subject to rotating the power of the nibbling effect of roller 3, and material is forced by between two rollers, is subject to simultaneously the extrusion-rolling of roller 3 and cuts mill, material namely starts cracked, granule after cracked, along the tangent line of roller 3 rotations, by the gap of two rollers 3, is dished out to roller 3 belows, the large granular materials that surpasses gap continues to be fractured into granule discharges, and falls in feeder.

The utility model multiple roll crusher, can push pulverizing to the raw material of the complex contour types such as building waste, shale, gangue; Roller 3 can arrange more than three or three, and compared to two rollers 3, material broken in the unit interval is more; The axial length of roller 3 is longer, and the contact-making surface between roller 3 and roller 3 is larger, and material that can be broken in the unit interval is more, high efficiency.
