II. Basic Information on the Equipment

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 separates, removes moisture from, 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.

2. Working Principle

1) The vibrating motor causes the screening body to move reciprocally at an upward angle, flinging the material diagonally upward and enabling it to advance uniformly. 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 drop onto the next layer of screening mesh for further separation. Finally, the qualified material moves forward and exits through the product outlet, 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 the two exhaust ports of the vibrating screen, effectively achieving the purpose of dehumidifying and cooling the material.

3. Equipment Configuration

1) Installation dimensions: Length 2025mm × Width 650mm × Height 1250mm
2) Vibration motors: 0.15 kW × 2 units, Ouli - Wolong
