PGZ scarper bottom discharge centrifuge

Structures and properties,

Model PGZ centrifuge is the filter equipment with scraper bottom discharge and intermittent operation, The material is fed into the drum from the top; under the action of the centrifugal force field, liquid-phase passed through the filter medium and the discharged out of the machine, while the solid-phase material is retained inside the drum and after the speed of the drum is reduced, it will be scraped off by the scraper and discharged out of the machine from the bottom. The centrifuge has such features as smooth running easy & convenient operation, etc. For model PGZ centrifuge, procedures can be preset in accordance with the requirement for work processes as automatic feeding, separating, washing, dehydrating, discharging, etc. The machine can be operated at either a close or a long distance, it has such features as high level of automation, large handling capacity, good separating result, etc. Model PGZ centrifuge has got rid of traditional suspending type of leg-support, instead, it adopts flat-plate counterweight and high-viscosity damping agent vibration isolator for absorbing the vibration and the installation requires no foundation.
