They are widely used in plastic products, building materials, medical devices and other fields.

[0003] The centrifugal device for PVC processing aids is a device used to separate the water or solid particles after centrifugation in the centrifuge, usually including the centrifuge body, centrifugal screen plate, motor and other components. During operation, the centrifuge generates centrifugal force through high-speed rotation to separate the water or solid particles in the mixture. After screening by the centrifugal screen plate, the water or solid particles are discharged, thereby achieving the separation and treatment of PVC processing aids. The centrifugal device is efficient, fast and reliable, and can effectively improve the production efficiency and quality of PVC processing aids.
