Hydraulic Pusher Centrifuge

Industrial processes that involve separating crystalline solids from liquids require equipment capable of delivering continuous performance, high efficiency, and reliable operation. A Hydraulic Pusher Centrifuge is specifically designed to meet these requirements by combining high-speed centrifugal separation with a hydraulic pusher mechanism that enables uninterrupted solid discharge.

Widely used in chemical, fertilizer, pharmaceutical, food processing, and mineral industries, this centrifuge ensures consistent product quality, reduced moisture content, and increased production efficiency.

What is a Hydraulic Pusher Centrifuge?

A Hydraulic Pusher Centrifuge is a continuous filtration centrifuge that uses a hydraulic system to move separated solids through the rotating basket while liquid passes through the filter media under centrifugal force.

Unlike batch centrifuges that require frequent stopping for product discharge, a hydraulic pusher centrifuge continuously feeds slurry, filters the liquid, dewaters the solids, and automatically discharges the final product. This makes it ideal for high-capacity industrial applications where uninterrupted production is essential.

How Does a Hydraulic Pusher Centrifuge Work?

The operation of a Hydraulic Pusher Centrifuge consists of several continuous stages:

1. Continuous Slurry Feeding

The slurry is continuously introduced into the rotating basket through the feed system.

2. Centrifugal Separation

As the basket rotates at high speed, centrifugal force separates the liquid from the solid particles.

3. Filtration

The liquid passes through the perforated basket and filter screen while solids remain inside.

4. Hydraulic Pushing

A hydraulic piston repeatedly pushes the crystal bed toward the discharge end, allowing continuous movement of solids.

5. Crystal Washing

If required, wash liquid is sprayed over the solids to remove impurities.

6. Dewatering & Discharge

Additional centrifugal force removes remaining moisture before the solids are discharged automatically.
