KIS have developed a solution to secondary screening at high production and maintaining efficiency. The machine runs faster and at a steeper angle than traditional trommels creating more surface area than conventional screening.

KIS conducted a trial on the Secondary Trommel screening materials with varying moisture. The results showed that the action of the Secondary Trommel provided attrition to shake clay that had adhered to the source rock. The trommel is capable of production rates in excess of 1000 tonnes per hour.

Some examples of applications for the Secondary Trommel are;

  • Primary crusher feed with clay bands – to be used in conjunction with the Primary Trommel
  • High efficiency secondary screening
  • Pre scalping of high plasticity clays prior to entering the crushing and screening circuit.
  • High efficiency secondary screening at high production rates

Loader Bin Benefits & Features

The Secondary Trommel runs faster and at a steeper angle than traditional trommels. The trommel consists of a variable speed barrel of 5-25 RPM and the barrel mainfall angle is at 10°

The Trommel barrel is  12m long and has a velocity of up to  2.6m per second and a  total screening area of 75m2
