The washing of aggregates is required for many markets and applications. Nowadays the finished product needs to meet specifications outlined by the ever stringent and demanding world markets. Where dry screening was accepted in the past, washing and scrubbing are now required to produce a silt free product.
A typical rinsing set-up would be used when the material does not require scrubbing, only rinsing to remove small particles of silt and fines to produce a clean end product.
The scrubbing process is required when dry and other deleterious materials are present, the process of high speed scrubbing is an accepted method. Scrubbing works on the principle of working material against material to remove clay and other materials from stone before moving on to the next stage.
