Description

Multi-stage pair roller crusher

Technical Field

The utility model belongs to the technical field of the production equipment technique and specifically relates to a multistage pair roller crushed aggregates machine is related to.

Background

A crusher is a machine that crushes large-sized solid raw materials to a desired size. The traditional material crushing machine generally adopts a heavy-load mode to crush materials, and because a heavy-load hammering mode needs to lift a heavy object to a high place to fall down, the required energy is large, and more dust is generated; meanwhile, the method has great potential safety hazard and produces serious production safety accidents. The material particle size after traditional mode of heavily pressing rolls, and a general heavily presses the apparatus and only corresponds a material particle size, and the mode of heavily pressing produces the noise very big moreover, and is great to user's hearing damage.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a multistage pair roller crushed aggregates machine.

In order to solve the technical problem, the utility model discloses a technical scheme as follows: multistage pair roller crushed aggregates machine, including feed hopper, crushed aggregates device includes a plurality of crushed aggregates units, the crushed aggregates unit is stacked up by supreme detachably in proper order down and is formed the crushed aggregates device, communicate each other between each crushed aggregates unit, wherein the top of upper portion crushed aggregates unit with feed hopper intercommunication, the crushed aggregates unit bottom of lower part is equipped with the stabilizer blade, crushed aggregates device exit end below corresponds there is the material receiving box.

Further, the crushing unit comprises a shell with an upper opening and a lower opening, two equal-height rolling rollers which are not in contact with each other are arranged in the shell, the rolling rollers are driven by respective driving motors behind the rolling rollers, and the rotating directions of the rolling rollers are opposite.

Further, the spacing between the grinding rollers in the plurality of crushing units is gradually reduced from top to bottom.

Furthermore, the number of the crushing units is 2-8.

Further, the surface of the rolling roller is provided with a convex tooth part.

To sum up, the utility model discloses compare in the beneficial effect that traditional mill was ground and be:

1. the utility model discloses the mode that need not give up original heavily pressing adopts multistage pair roller to roll pulverizes the fragility material, and the crushed aggregates mode is milder and safe relatively more pressing, and the material texture after rolling is even.

2. The utility model discloses can select several grades of crushed aggregates units as required to roll, be suitable for most of crushed aggregates occasions, small in noise does not produce the dust, and the range of application is extensive.

Drawings

The foregoing and other objects, features, and advantages of the invention will be apparent from the following detailed description taken in conjunction with the accompanying drawings.

Fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic view of a unit structure of the new material crushing device;

fig. 3 is a schematic structural view of a driving motor of the material crushing unit of the present invention.

Wherein: 1. the material receiving device comprises a feeding hopper, 2 crushing units, 21 shells, 22 rolling rollers, 221 teeth, 3 supporting legs and 4 material receiving boxes.

Detailed Description

In the following, the preferred embodiments of the present invention will be explained, and various changes and modifications can be made by workers without departing from the technical spirit of the present invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.

The invention will be further explained with reference to the following figures:

multistage pair roller crushed aggregates machine, including feed hopper 1, crushed aggregates device includes a plurality of crushed aggregates units 2, crushed aggregates unit 2 is by supreme detachably in proper order piles up the formation down crushed aggregates device, communicate each other between each crushed aggregates unit 2, wherein the top of upper portion crushed aggregates unit 2 with feed hopper 1 intercommunication, 2 bottoms of crushed aggregates unit of lower part are equipped with stabilizer blade 3, crushed aggregates device exit end below correspondence has and connects workbin 4. The material crushing unit 2 comprises a shell 21 with an upper opening and a lower opening, two equal-height rolling rollers 22 which are not in contact with each other are arranged in the shell 21, the rolling rollers 22 are driven by respective driving motors at the rear of the rolling rollers 22, the rotating directions of the rolling rollers 22 are opposite, and the rotating speeds are consistent. The spacing between the milling rollers 22 in the plurality of crushing units 2 is gradually reduced from top to bottom. The number of the crushing units 2 is 4. The surface of the rolling roller 22 is provided with a convex tooth part 221.

The utility model discloses a theory of operation brief:

referring to fig. 1, the utility model discloses a level four crushed aggregates unit 2 is once from last to grinding down the interval between the roller 22 and is 16mm, 8mm, 4mm, 1mm, in the quiet feed hopper 1 of brittle material about diameter 30mm gets into level one-level crushed aggregates unit 2, is smashed and gets into second grade crushed aggregates unit 2 behind 16mm in, so on, gradually get into level four crushed aggregates unit 2 in and by the tiny granule of grinding about 1mm, enter in the case of receiving 4 side by side.

The utility model discloses the tooth portion 221 on rolling roller 22 surface is in order to make rolling roller 22 can "eat up" the material, prevents promptly that the material from skidding and not rolled always, gives a decurrent pressure to the material, makes it can be crushed by rolling roller 22 smoothly.
