Understanding the Operation of Pusher Centrifuge Machines

What is a Pusher Centrifuge?

Separating solids from liquids by centrifugal force is a process found in continuously operating pusher centripuges also called pusher centrifuges. Pusher centrifuges differ with other forms of batch centrifuges as they work on a continuous basis which is advantageous in mass production. They are especially useful in exacting fine powders from slurries, and a common practice in food manufacturing, wastewater treatment and Pharmaceuticals.

Main Parts of Pusher Centrifuge Machines

Rotating Drum: The main working unit of pusher centrifuge where the separation process takes place and which rotates at high velocity to provide the centrifugal acceleration to separate out the solids.

Pusher Mechanism: This part of the machine ensures that the solid cake is maintained and pushed towards the exit end of the drum. It promotes adequate movement of materials and avoids clogs without compromising on performance.

Feed System: The screw pump or pressure tangential inlet rends the slurry into the spinning drum feed system. Its purpose is to maximize the feed slurry distribution around the drum perimeter for an efficient separation process.

Liquid Discharge System: When the liquid mass and solid materials have been separated, the liquid phase that is not needed is sequentially removed from the drum out through the drum body to drainage systems through a pipe.

Working Principle of Pusher Centrifuges

Slurry Feeding: The feed system ensures that the slurry enters into the rotating drum. A very important aspect of designing the feed system is the feed nozzle that maximally suppresses feed entry unevenness into the drum from both ends.

Centrifugal Separation: While pentapod actuates, the drum begins rotating, so centrifugal force is applied on slurry. Denser solids move outward and build up against the wall of the drum and this is termed as a solid cake. Likewise, lighter liquid remains towards the plane of the center of the drum.

Solid Cake Removal: The pusher turns the solid cake to the discharge end using a pushing device. Solids collected in the drum can be discharged without interruption due to the movement constantly.

Liquid Discharge: The outlet of the liquid phase has to be drained away from the drum as this is usually done through the incorporation of another outlet. Through this methodology, separation of materials is much enhanced with little solids carryover.

Advantages of Pusher Centrifuge Machines

Continuous Operation: Compared to batch centrifuges, pusher centrifuges allow uninterrupted operation – making these suitable for mass industrial needs.

High Efficiency: The pusher mechanism design of the solid/liquid separation apparatus and rotating drum enables most of the liquid separation to be conducted with dry solids.

Versatility: Thanks to their construction, pusher centrifuges are capable of processing many different types of materials ranging from finest powders to the most coarse solid elements which makes them useful in variety of industries.

Reduced Labor Costs: The operating procedures and processes involved in the use of pusher centrifuges where little manual intervention is utilized lowers labor costs and enhances safety.
