Description

Technical Field

[0001] The utility model relates to the field of micro-cement processing, and more particularly to a screening device used for micro-cement processing. Background Art

[0002] Microcement is very common in construction projects. As a common building material, cement plays a vital role in construction projects. In the production and processing of microcement, microcement particles of different sizes often exist. Therefore, a screening device is needed to screen microcement particles of different sizes and select suitable microcement particles for use. In the screening process, the existing screening device generally screens the microcement particles through a screen. During the screening process, the fluidity of the microcement is poor, so that the microcement particles cannot pass through the screen smoothly, thereby affecting the screening of the microcement and affecting the production and processing of the microcement. At the same time, the existing screening device lacks a crushing structure and can only perform screening. Large microcement particles cannot meet the use requirements. When the microcement particles that cannot pass through the screen remain in the screening device, they can only be taken out and then crushed and screened, thereby reducing the production and processing efficiency of the microcement, affecting the production and processing of the microcement.
