[0002] In the production and processing of coated sand, crushing and screening are extremely critical processes. Coated sand is usually composed of raw sand, resin, curing agent and other components. In the crushing process, larger particles of coated sand material are broken into fine particles that meet specific particle size requirements. In the screening process, coated sand of different particle sizes is further separated and screened. However, these processes inevitably generate a large amount of dust. On the one hand, during the crushing process, mechanical force acts on the coated sand to break it, causing small sand particles, resin particles, curing agent dust, and other particles to separate from the main body and disperse in the air. In the screening stage, due to the movement of the material, vibration, and the separation of particles of different sizes, a large amount of dust is also raised, so a dust collecting device for coated sand crushing and screening is needed.
