III. Basic Information of the Equipment

3.1 Scope of Application

The cooling, dehumidifying, and vibrating screen is widely used for final product screening, heat dissipation, and moisture removal in modified plastics.

Features:

1. The heat-dissipating and dehumidifying vibrating screen effectively screens, removes moisture, and dissipates heat from the material.

2. The cooling, dehumidifying, and vibrating screen operates quietly, and its sealed mesh prevents external contamination of the material.

3. Simple structure and easy to clean.

3.2 Operating Principle

1) The vibrating motor causes the screening body to move reciprocally at an upward angle, flinging the material diagonally upward and propelling it uniformly forward. As the material passes through the mesh openings of the first-layer screen, larger particles continue moving forward and are discharged from the coarse-material outlet. Meanwhile, the qualified and finer materials fall onto the next layer of screening mesh for further separation. Finally, the qualified materials advance toward the outlet for finished products, while the fine particles collect in the powder collection box located at the bottom of the vibrating screen.

2) While the vibrating screen is separating materials, a blower at the bottom of the screen body forces filtered air through the interior, carrying away moisture and heat from inside the screen. This air is then expelled via two exhaust ports on the vibrating screen, effectively achieving the purpose of dehumidifying and cooling the material.
