Vibrating spiral elevator is a vertical conveying and cooling system designed for high-temperature pellets that require rapid and uniform cooling after pelletizing. It is widely used in engineering plastics and heat-sensitive materials, such as PP glass fiber compounds and PVC composites. Powered by dual counter-rotating vibration motors, the Cowin spiral vibratory conveyor generates high-frequency, low-amplitude vibration, enabling materials to move upward along the spiral trough through inertia and friction. During conveying, pellets are fully exposed to air, achieving efficient lifting combined with cooling or drying. The long spiral path ensures excellent heat dissipation, while the compact vertical structure saves valuable floor space. With gentle conveying, low energy consumption, simple maintenance, and optional functions such as cooling, drying, heating, or grading, the system meets diverse process requirements.
Field Designed specifically for high-temperature materials requiring rapid cooling after pelletizing, it is mainly applied in the engineering plastics or heat-sensitive material, such as the pelletizing and cooling process of PP glass fiber or PVC composites.
Taking vibration motors as the power source, two counter-rotating vibration motors generate a combined vibratory couple, driving the machine body to vibrate with high frequency and small amplitude on shock absorbers. Driven by vibration, materials move upward along the spiral trough surface relying on inertia and friction, while fully contacting with air to achieve simultaneous lifting and cooling/drying.
High-efficiency Cooling
The long spiral path ensures uniform material dispersion, resulting in high cooling efficiency. It is suitable for the rapid cooling demand of high-temperature engineering plastics like PP GF after pelletizing.
Space-saving
The vertical spiral structure features a small floor footprint, making it ideal for compact workshop layouts. Low-damage Conveying The stable vibration conveying minimizes damage to the particle morphology, preserving material integrity.
