Description

A multi-roll crusher with a material conveying device

technical field

The utility model belongs to the technical field of building material machinery manufacturing, in particular to a multi-roller crusher with a material conveying device.

Background technique

Roller crushers can be divided into single-roller, double-roller and multi-roller crushers according to the number of rollers used. The friction force of the roller surface is used to bite the material into the crushing area, so that the material is squeezed or split and crushed. It is suitable for medium hardness materials, such as ore, rock and other coarse crushing, medium crushing or fine crushing operations.

At present, the roller crusher commonly used by brick and tile production enterprises has the following deficiencies and defects:

It is necessary to place a collection tank at the discharge port, and then transport it manually, which is inefficient and does not realize the automatic transportation of processed materials;

Ordinary double-roll crushers can only crush some small-grained raw materials, and cannot enter between the two rollers for crushing of larger raw materials;

For those raw materials with complex shapes and high strength, such as complex construction waste, shale, and coal gangue, they cannot be fully squeezed and crushed;

The working efficiency is low, the axial length of the roller surface is short, generally there are only two rollers, and the amount of raw materials that can be crushed per unit time is small.

Detailed ways

As shown in Figure 1, the multi-roller crusher with a material conveying device of the present invention includes a conveying device, a roller breaking unit and a casing; the conveying device includes a motor 1, a driving roller 4, a driven roller 5, a conveying belt 2 and a conveying frame 3. The driving roller 4 and the driven roller 5 are installed on the transmission frame 3 , the driving roller 4 and the driven roller 5 are covered with the conveyor belt 2 , and the motor 1 is connected with the driving roller 4 .

There are three or more groups of roller crushing units. The roller crushing unit includes a motor 1, a reducer 6, a roller 7 and a roller shaft 8. The roller surface of the roller 7 is tooth-shaped, and the rollers 7 are all on the same horizontal line and parallel to each other. The roller 7 is mounted on a roller shaft 8 . The motor 1 is connected with the reducer 6 , the reducer 6 is connected with the roller shaft 8 , and the reducer 6 is fixed on the base 10 through the reducer bracket 9 .

The casing includes a base 10, a bearing seat 11 and a guard plate 12, the bearing seat 11 and the guard plate 12 are installed on the base 10, the two ends of the roller shaft 8 are installed on the bearing seat 11, and the roller 7 is arranged in the guard plate 12 ; The transmission device is set under the base 10 .

As shown in Figure 2, there are three rollers 7, and the rollers 7 are arranged in the guard plate 12. The roller surface of the rollers 7 is tooth-shaped, and the three rollers 7 are all on the same horizontal line and parallel to each other.
