Log Washers

Logwashers are designed to remove heavy or plastic clays from aggregates. The very robust Parnaby logwasher can clean material with up to 20% clay contamination with throughputs of up to 200 tonnes per hour.

Operation

The logwasher comprises an inclined trough fitted with two counter-rotating shafts with high-tensile blades.  The rotating shafts mill and wash the raw material creating a lot of turbulence.

As in a screw separator, the heavier aggregate material is pushed forwards to the discharge chute.  The water and broken down clay particles overflows the rear of the logwasher.
