PGZ horizontal scraper unloading centrifuge is a continuous operation of solid and liquid separation equipment. It has a fixed filter bed and periodically performs feeding, separation (dehydration), washing, and unloading processes under the action of centrifugal force. It is automatically controlled by the combination of hydraulic pressure and electrical appliances. The horizontal scraper discharge centrifuge has a wide range of applications. It can be used for the separation of solid and liquid two-phase suspensions containing solid particles with a particle size of about 10um. The mass fraction of the solid phase in the suspension is greater than 25%. This model is more suitable.
