A powder separator for cement preparation

Abstract

The invention relates to the technical field of cement processing equipment, and discloses a powder classifier for cement preparation, which includes a shell, the shell and a feeding pipe, the inner cavity of the shell is fixedly installed with a support frame, and the shell A motor is fixedly installed on the top surface of the motor, the output end of the motor is fixedly sleeved with a main shaft, and the surface of the main shaft is movably sleeved with a grinding plate and a screen, and the side walls of the grinding plate and the screen are fixedly installed with guide block. In this powder separator for cement preparation, the motor drives the bar to rotate, and the bar is movably connected in the card slot through the main shaft to drive the grinding plate and the screen to rotate. The rotation of the grinding plate is guided by the upper slide rail and the lower rail. When rotating to the bottom groove, the bottom surface of the grinding plate is in contact with the top surface of the screen, and the larger particles on the top surface of the screen are ground. It is not necessary to collect the larger cement particles and send them into the grinding equipment, reducing the burden on the machine. The burden of the first process and improve the working efficiency of the device.

Description

technical field [0001] The invention relates to the technical field of cement processing equipment, in particular to a powder separator for cement preparation. Background technique [0002] Cement is one of the essential raw materials for construction. With the development of society, the demand for cement is also increasing. The cement production process is cumbersome and has many steps. One of the steps is to use a powder separator to dry The cement is sieved. [0003] Most of the existing powder separators use sieves to sieve cement when sieving cement. The cement particles that meet the requirements will fall directly through the sieve holes for collection, while the larger cement particles will be collected. After centralized collection, it enters the previous process for the second time, and then grinds again. The larger particles in the second grinding may increase the workload of the previous process, reduce the working efficiency of the device, and reduce the pract...

Problems solved by technology

[0004] Most of the existing powder classifiers are fed directly through the feeding pipe when feeding. When the cement particles enter the screen in the device from the feeding pipe, the cement particles may be piled up in one place, which may cause the cement particles to fall on the screen. Uneven distribution reduces the utilization rate of the screen, making the screen unable to fully function and reducing the working efficiency of the device;

[0005] Existing powder classifiers sieve through the sieve holes on the sieve. When sieving, there may be cement particles with the same sieve diameter. When the screen is sieved, it may cause the blockage of the sieve, and the screen needs to be removed for cleaning, which increases the labor intensity of the user and reduces the working efficiency of the device.
