Did you know...Did you know...Trommel fi nes typically comprise of 80% material that, if separated, would qualify for the lower UK landfi ll tax, saving an operator generating 10,000 t/year over

£640,000!

Separation of the lightweight fl oating materials is achieved by the use of an axial fl ow pump to induce an up fl ow current within the separation chamber.

This upfl owing current carries the lighter “fl oat” material up to the waters surface and onto a mesh conveyer which then carries the lighter materials out of the separator.

The water drains through the belt and is recirculated back to the separation chamber via the axial fl ow pump.

Dense particles that settle faster than the up fl ow current drop to the bottom of the chamber where an Archimedes Screw moves the material up an inclined trough.

By using water as the separation media, the performance of the unit can be optimised by simply varying the speed of the axial fl ow pump

How it works

The Gritbuster HDS (Hydraulic Density Separator) unit has been designed to provide customers with a means of separating light, low density particles from dense particles (eg. organic material from sand and gravel), making it the ideal solution for recovery of unwanted contaminants from granular material and recycled aggregates.

Depending on the nature of feedstock the Gritbuster HDS can process upto 15 to 20 tonnes per hour.

The Gritbuster HDS can be used for standalone material processing, with its own recirculating water treatment plant or can be fully integrated with our range of Gritbuster washing systems to provide a complete washing, destoning and separation solution.
