[0002] Crusher is a kind of equipment used to crush and process various hardness and brittle materials. It is usually used in industries such as ore processing, building materials, chemicals, metallurgy and energy. Multi-stage compound crusher combines the advantages of impact crushing and hammer crushing. Through multi-stage crushing and screening processes, it crushes the raw materials to the required particle size and produces high crushing efficiency and good finished product shape.

[0003] In the prior art, for example, Chinese patent number: CN217221849U discloses a multi-stage compound crusher. Aiming at the problem that it is inconvenient to crush construction waste and it is inconvenient to adjust the degree of crushing of construction waste during crushing, the following scheme is proposed, which includes a chassis, a feed pipe is fixedly connected to the top of the chassis, a guide plate is fixedly connected to the inside of the chassis, two connecting plates are fixedly connected to the outer wall of the chassis, the outer walls of the two connecting plates are fixedly connected to a first motor, one end of the output shaft of the first motor is fixedly connected to a roller, the outer wall of the roller is evenly fixedly connected to a plurality of crushing blocks, and the inside of the chassis is fixedly connected to a support plate. The utility model drives the annular baffle plate to move downward through the air cylinder, so that the distance between the conical crushing plate and the annular baffle plate becomes smaller, thereby adjusting the degree of crushing of the construction waste.

[0004] Although the above scheme has the above advantages, the disadvantage of the above scheme is that when using the compound crusher to crush the material, the material needs to be crushed to the required size. The crushing scheme of the device is relatively single, which may easily cause insufficient crushing of the material. In the later use, it may be necessary to repeat the crushing many times, which increases the use cost to a certain extent. At the same time, there is a lack of necessary material conveying device. After the material is crushed, it needs to be manually taken out of the device, which consumes a lot of material and manpower, which is not conducive to the promotion and use of the crusher.

[0036] How it works

[0037] When in use, the material to be crushed is put into the feed port 1, and the first motor 4 is started. The first motor 4 drives the column 8 to rotate.

The second motor 5 drives the first rotating shaft 16 to rotate, and the first rotating shaft 16 drives the conveyor belt 6 to rotate, and the crushed material is transported out from the inside of the second crushing bin 2, which solves the problem in the prior art that when using a composite crusher to crush materials, the material needs to be crushed to a required size. The crushing scheme of the device is relatively single, which is easy to cause insufficient crushing of the material. In the later use, it may be necessary to repeat the crushing multiple times, which increases a certain amount of use cost. At the same time, there is a lack of necessary material conveying device. After the material is crushed, it needs to be manually taken out of the device, which consumes a lot of material and manpower, which is not conducive to the promotion and use of the crusher.
