PUSHER CENTRIFUGES

Pusher centrifuge

 

 

 

Pusher centrifuge fulfils its separation task reliably and efficiently in numerous applications for the chemical,pharmaceutical and food industries. Its strengths are most evident for special process requirements: long retention times, low solids loss in the filtrate, low crystal breakage and abrasion, intensive solids wash and minimum wear. These features make it an outstanding machine for most crystalline products,e. g. potassium sulphate or potassium chloride, sodium chloride, ammonium chloride and other sulphates,it can also be used as a product solution that requires drying.

 

While a trend to standardization is generally observed, we continue to cooperate with customers for special applications. In this manner, optimum efficiency can be achieved and individual requirements met.

 

The pusher centrifuge must be designed for the product, process and operating parameters to meet the customer's performance and efficiency requirements. Our centrifuge company's 'rich experience and targeted trials will solve all your worries.

 

 

Function and design variables

The pusher centrifuge belongs to the continuously working filtration centrifuge. The solids are retained on the wedge wire basket and transported by a movement of the inner basket axially in the direction of the solids discharge. This results in a longer retention time of the material, allowing lower discharge moistures and washing function when needed.

 

The thick enough filter cake ensures a good yield of even very fine particles. According to the test and our experience, the production capacity of materials with an average particle size larger than 80μm will be greater.Because of the features of this centrifuge,the materials on the screen can have long retention time and enough thickness – allow additional dewatering of solids coming from other types of filters after initial drying, e. g. filter press or belt filters.

 

We offer a wide range of pusher centrifuges for a variety of products ,so as to serve for a variety of new applications or processes. Currently we manufacture with basket diameters from 250 mm to 1,260 mm,and design with one, two or three stage rotating parts depending on different products.

 

The specific selection is determined based on the following factors:

  • Type of product
  • Capacity
  • Particle size
  • Solids concentration
  • Washing or not

 

We also have more professional designs that not only further enhance the removal of residual moisture from the material, but also improve the efficiency of the entire equipment thrust.

 

In addition, through the scientific design of the material compartment partition, the mother liquor with high concentration and the washing water with low concentration can be separately collected and discharged to improve the recovery rate of materials.

 

This centrifuge has a modular design, and the various parts are easy to overhaul and disassemble; by combining with various sensors, the equipment can be controlled fully automatically.
