KISA Logwashers

General

KISA log washers are designed for washing muddy feedstock.

• Grain sizes: to 250 mm

• Throughput: 40 t/h to 600 t/h

• Length of trough: 4 to 10 m

Our Logwashers

Highly efficient washing results for a wide variety of rock types are achieved with a KISA heavy-duty wash.

Clay, loam, and other impurities are grated by rotating intermeshing paddle shafts and directed out of the sword wash via a predefined water flow. Suspended solids such as wood and foliage are also separated from the rock and discharged from the machine.

The KISA Log Washers are characterized by a robust design. Even under rough operating conditions, a long service life can thus be achieved if all maintenance work is carried out properly

Mode of operation:

A Log washer is set up at an angle, with the outlet at the top. The contaminated rock is fed in at the bottom, inclined upwards, conveyed through the machine and cleaned in the meantime. Two counter-rotating paddle shafts, with paddle arranged in a spiral, rub the impurities from the rock and convey it upwards at the same time.

Opposite to the conveying direction, a water flow runs through the machine, which causes a clear separation between the clean rock and the impurities.

Design:

Depending on the requirements, we adapt the machine together with the customer. For example, if the rock is heavily contaminated, we lengthen the trough or increase the trough inclination to extend the washing time.

Common variables are: the trough length; the inclination of the machine; the electrical drive power; and the water feed.

The actual size depends on the throughput capacity.
