PB Series Closed Centrifuge

PB series centrifuges are fully enclosed closed upper discharge filter centrifuges designed in accordance with GMP specifications and environmental protection requirements. The motor is stably started by frequency conversion control (clutch can also be used), and drives the drum through the transmission system to make the drum rotate at high speed around its own axis, forming a centrifugal force field.

Working principle

PB series centrifuges are fully enclosed closed upper discharge filter centrifuges designed in accordance with GMP specifications and environmental protection requirements. The motor is stably started by frequency conversion control (clutch can also be used), and drives the drum through the transmission system to make the drum rotate at high speed around its own axis, forming a centrifugal force field. The feeding speed, cleaning speed and liquid removal speed can be arbitrarily selected within a certain speed (0- rated speed). Under the action of centrifugal force field, the materials are uniformly distributed on the drum wall for liquid removal and separation. The liquid phase passes through the gap between the solid materials and the filter screen (bag), is thrown to the shell cavity through the drum wall hole, and is discharged from the chassis liquid outlet. The solid materials are intercepted in the drum. The feed liquid is added through the feeding pipe, and the washing water is added through the washing pipe for feeding, Washing can be controlled by a special valve. The material is dehydrated. After washing, the machine stops. With the help of a specially designed balancing device, open the machine cover and unload the material.

Parameter selection

1. Loading volume (loading limit)

2. Maximum rotating speed of drum (maximum separation factor)

Main features

1. Novel structure and convenient operation and maintenance.

2. Te fully enclosed structure design improves the working environment and meets the requirements of GMP and environmental protection. The inner chamber of the centrifuge is protected by nitrogen, which fully meets the requirements of airtight explosion-proof.

3. The large machine cover is adopted, which is convenient for unloading and can thoroughly clean the interlayer space between the shell and the drum.

4. Mechanical balancer is equipped for cover opening, which saves labor and energy.

5. It is equipped with frequency conversion program control system, with stable startup, program setting (the whole process of feeding, filtering, washing, etc. is fully automated), energy consumption (feedback) braking, no

Friction dust pollution, no friction heating, safer operation.

6. The internal and external surfaces are polished without dead corners, with smooth transition. Online cleaning (material cleaning and machine cleaning) is provided to achieve the washing effect.

7. The grains are not easy to be damaged.

Performance and Application

Pb series centrifuges have strong adaptability to materials. They can separate fine particles with particle size of micron, and can also de liquefy finished articles. They can separate all kinds of suspensions that are difficult to separate. The grains are not easy to be damaged by manual unloading. For example, gypsum, ammonium sulfate, copper sulfate, potassium chloride, borax, dyes, resins, pesticides and other chemical industries, salt, monosodium glutamate, food additives, starch, sugar, condiments and other food industries, antibiotics, vitamins and other pharmaceutical industries, copper, zinc, aluminum and other mineral products, as well as environmental protection (sludge and sewage treatment) industries.

Material selection

Due to the need of corrosion protection, other materials can be used according to customer requirements, such as sus316316l, 321304, titanium, Hastelloy, plastic lining, rubber lining, spraying F46, etc.
