Product Introduction

The PGZ Vertical Automatic Bottom Discharge Centrifuge is a fully automatic vertical machine developed by Jiangsu Shengli Centrifuge Manufacturing Co., Ltd. for separating highly viscous, fine-grained, toxic, and flammable or explosive materials. Its vertical flat-plate design integrates feeding, primary filtration, washing, fine filtration (dewatering), and discharge in one PLC-controlled cycle. A pneumatic or hydraulic scraper system removes the cake through the bottom opening of the bowl. With a high degree of automation, large throughput, and remote-control capability, the PGZ significantly reduces labor intensity and serves as a reliable workhorse for high-volume chemical, pharmaceutical, and food production.

Working Principle & Standard Manufacturing Form

The standard machine features a flip cover, feed pipe, washing pipe, sight glass, exhaust port, and lighting hole in a fully enclosed structure. The bowl, casing, and small flip cover are made of stainless steel (SUS304); cast parts such as the machine base are clad in stainless steel; and the inner and outer surfaces of the bowl and casing plus all exposed parts are polished. All fasteners on the cover and casing are stainless steel. Control is by PLC with electromechanical level control; drive and braking use a standard (or explosion-proof) motor + frequency converter + regenerative braking; scraper motion is driven by pneumatic or hydraulic systems. The foundation-free design (counterweight + imported high-precision liquid-damper vibration isolators) allows installation directly on floors without a dedicated foundation.

Product Applications

Mainly used for solid-liquid separation of suspensions containing solid particles, and also for fibrous materials—especially high-viscosity, fine-particle, toxic, flammable, and explosive media. Typical materials include antibiotics, vitamins, and pharmaceutical intermediates; salt, monosodium glutamate, food additives, starch, sugar, and chemical seasonings; ammonium sulfate, gypsum, Glauber's salt, copper sulfate, potassium chloride, borax, dyes, pigments, resins, and pesticides; as well as solid-liquid separation duties in mining and environmental protection.

Industry Application Cases & Market Insights

As the global specialty and fine chemical industries upgrade toward higher value, continuous, and cleaner production, scraper bottom-discharge centrifuges have become mainstream equipment for crystallization separation, thanks to their large throughput, high automation, and remote monitoring capability. Typical scenarios include food-grade salt and MSG (monosodium glutamate) production, separation of fertilizer salts such as ammonium sulfate and potassium sulfate, and dewatering of FGD and industrial by-product gypsum. PGZ units from Jiangsu Shengli Centrifuge Manufacturing Co., Ltd. run stably in numerous domestic projects and have entered Southeast Asia, the Middle East, and Central Asia through the company's export network, winning repeat orders with fast delivery, strong value, and responsive service.

Key Advantages

• Fully enclosed structure with nitrogen protection for closed, explosion-proof processing of toxic and flammable media.
• PLC + variable-frequency control with remote monitoring enables unattended automatic cycling.
• Bowl, casing, and product-contact parts in polished stainless steel, compliant with GMP requirements.
• Foundation-free design (counterweight + imported high-precision liquid-damper isolators)—all machine vibration is absorbed by the isolation system without disturbing the floor or surrounding environment.
• Electromechanical level control for accurate feed volume, preventing overflow and excessive vibration.
• Large throughput and high automation markedly reduce labor intensity and labor cost.
