Sand Washing and Desliming. Silica sand pumped from the pit is passed over a screen, either stationary, revolving or vibrating type, to remove tramp oversize. The screen undersize is washed and dewatered generally in a spiral type classifier. Sometimes cone, centrifugal and rake type classifiers may also be used for this service.
The production of these specialist silica sands for application in glass manufacturing requires specialist screening and classification equipment from CDE. This complex process will first involve a detailed analysis of your feed material both in terms of the particle size distribution (PSD) and the chemical properties of your silica sand.
