Description

Technical Field

[0001] The utility model belongs to the field of cement clinker crushing and processing, in particular to a cement clinker crusher. Background Art

[0002] In the process of cement production, most raw materials need to be crushed, such as limestone, clay, iron ore and coal. Limestone is the raw material with the largest amount of cement production. After mining, limestone needs to be crushed and then sent to the rotary kiln. It is calcined into blocks at high temperature. At this time, cement is called cement clinker. At this time, cement clinker still needs to be crushed by a crusher, and finally the cement clinker is ground into powder. The crushing process is more economical and convenient than the grinding process. It is very important to choose crushing equipment and grinding equipment reasonably. Before the material enters the grinding equipment, the large pieces of material should be crushed into small and uniform particle sizes as much as possible to reduce the load of the grinding equipment and increase the output. After the material is crushed, the separation of materials of different particle sizes during transportation and storage can be reduced, which is conducive to obtaining raw materials with uniform composition and improving the accuracy of batching.

[0003] The Chinese patent with the announcement number CN213315412U discloses a new type of cement clinker crusher, including a main body, a shock-absorbing telescopic cylinder, a coil spring and a spring baffle. A feed port is arranged on the upper part of the main body, and a dust shield is arranged on the side wall of the feed port through a hinge. A return spring is arranged between the dust shield and the side wall of the main body, and one end of the return spring is connected to the dust shield, and the other end is connected to the side wall of the main body. A crushing shaft is rotatably arranged on the side wall of the main body below the feed port, and a plurality of blades are arranged on the crushing shaft. One end of the crushing shaft passing through the side wall of the main body is connected to a motor. Below the crushing shaft, a primary screen plate is also obliquely arranged inside the main body. One end of the primary screen plate is inclined upward and connected to the side wall of the main body, and the other end is inclined downward and extends into the recovery cavity of the main body, and is fixed in position by a partition plate. Below the primary screen plate, a secondary screen plate is obliquely arranged. One end of the secondary screen plate is inclined upward and connected to the side wall of the main body, and the other end is inclined downward and extends into the recovery cavity, and is penetrated into the middle through hole of the partition plate. Screening holes are arranged on both the primary screen plate and the secondary screen plate. A discharge port is arranged on the bottom surface of the recovery cavity, and a discharge port is also arranged on the bottom surface of the main body and on one side of the recovery cavity. A shock-absorbing telescopic cylinder is arranged at the bottom of the main body, and a coil spring is arranged on the outer sleeve of the shock-absorbing telescopic cylinder. A spring baffle is arranged at the bottom of the shock-absorbing telescopic cylinder, and the upper and lower ends of the coil spring are respectively against the main body and the spring baffle.
