The design of the QUILTON grit washer involves two core components: the grit washing tank and the discharge screw. The process of classifying and washing grit requires a small amount of water and low inlet pressures. The grit washer provides a high performance with low maintenance costs, delivering top quality grit with a reduced organic material content.
The QUILTON grit classifier and washer has been designed mainly for the following purposes:
The QUILTON grit washer may be upgraded to become a receiving station for sand from septic tanks. This involves mounting an input roughing station for the removal of solids and the subsequent washing and classifying of grit.
The option is available of mounting the grit washer on the desander’s gantry and feeding it with the cleaning water provided by the desander itself.
The equipment’s design and structural specifications make it suitable for outdoor operations, tolerating conditions of high humidity and low temperatures.
The mixture of grit and water is fed into the sand washer and classifier through the inlet flange on the washing tank. The grit precipitates in the tank more quickly, while the organic material remains in suspension longer. When the cleaning water is added, the sediment is separated from the remaining organic materials during the washing process. This washing process is enhanced by the use of a shaking device and upward currents. Finally, the grit is removed from the tank, dried, and offloaded via an screw.
