The automatic bottom discharge scraper centrifuge is vertical tuiiy-automatic filtration centrifuge. The motor drives the basket to rotate at high speed th rough the belt, and under the control of pre-written program, the material to be separated is fed into the basket through the feed system.

After the material is filtered through the filtration medium (filfe r cloth/screen) under the action of centrifu g al force, the liquid phase discharges out of the centrifuge through the liquid pipeline, and the solid phase is retained in the basket. A material detection device is used to detected material filling position in real-time manner and when the solid cake deposited in the basket reaches the specified holding capacity of the centrifuge, feeding stops. Then wash and dry the solid cake.

After the solid cake meets requirements for knock-out, the centrifuge reduces to the scraping rate, under the hydraulic (pneumatic) control, the scraper device removes the solid cake, and then the cake id discharged at bottom outlet of the centrifuge.

LGZ/PGZ Main Features

• Platform base structure could lower the center of gravity and stabilize the machine. No foundation construction makes convenient installation and repairing.
• Platform base with liquid damping isolators: Applying the liquid damping technique improves performance of vibration absorption in centrifuge.
• Inclined feed disk: we discarded the central feed or side feed method.
• Nitrogen protection system (optional) can meet the requirements of sealed explosion-proof, and is suitable for the application of toxic, flammable and explosive occasions. Ensure the safe operation of the machine.
• Big hinged cover and CIP system, which avoiding cross contamination against the products.
• Multiple safety protection devices: over vibration protection, over current protection, temperature control protection, material layer control, scraper stroke protection, open cover protection, mechanical and electrical interlock protection, various warnings and warning signs.
• PLC control, touch screen, inverter control, dynamic braking, feedback braking, self-diagnosis of equipment fault, automatic control panel and DCS control interface.
• Polished internal/external surfaces with roughness up to Ra0.2 - 0.4 μm, complying with the related requirements of cGMP.

In solid–liquid separation processes, incomplete cake removal can significantly reduce efficiency and increase downtime. This article explains why automatic vertical scraper centrifuges are an effective solution, helping users understand how advanced scraping and bottom discharge designs address common discharge challenges in industrial centrifugation.
