HEPU Pumpen und Maschinen GmbH

Description

The hydrocyclone is a classifying device of simple construction. It is used for solid-fluid-separation in many areas of application. Through the appropriate inlet pressure, produced by an upstream centrifugal pump, the solid particles in the suspension are separated on the basis of their weight difference from the fluid. Thus you receive an overflow that is almost clear. The outsize tolerance in the overflow lies between 1% and 5%.

Normally HEPU container pumps with recirculation equipment are used. Thereby a continual in feed of the hydrocyclone is achieved.

Use

The main use of hydrocyclones is the fine sand retrieval in sand and gravel mines. All of the washing water from the underflow of the processing machines is fed to the hydrocyclone by centrifugal pumps. Through a correct design of the cyclone system a selected cross-cut is achieved, and with it an economic extraction of fine sand is enabled. The proportion of fine sand extracted is drained either by a bucket wheel or drainage screen.

With the hydrocyclone cross-cuts of 10 µm to 300 µm are achieved. With clarified impurities less then 10 µm are used by HEPU's own round thickener. For that, 5 standard clarifiers are available. The maximum pulp quantity is 720 m3/h.
