Derrick Corporation specialises in fine screening, both wet and dry, with high frequency vibratory screening machines. Our own definition of fine screening is from 38 micron aperture to 10mm aperture and we use either wire cloth or our unique polyurethane cloth. Our unique urethane screen surfaces have a high open area, they do not blind and they are extremely strong. We manufacture these urethane surfaces as fine as 75 micron aperture. Our screening machines are fitted with high frequency, low amplitude motors that do not transmit vibration to the surrounding and/or supporting structures. The machines are generally lighter and smaller than conventional screening machines.
