We understand wet processing to mean the processing of clays with a moisture content greater than 12%. The main debate lies in the selection of equipment that can be used for secondary grinding, after a primary phase of crushing. In this case, the brickmaker should choose between the Wet Pan Mill and the Disintegrator Crusher, based on the cost and space available, the moisture content and abrasion rate of their clays, and the desired grind quality.
After this secondary grinding phase, it is best to use a Roller Mill to achieve more finely granulated clay. This is especially recommended if you want to produce added-value ceramic products, such as floor and roof tiles, facing bricks...
An Algerian client wanted to produce 270,000 t/year of hollow ceramic product and entrusted Verdés with the supply of a complete clay preparation and shaping line. Given that the available raw material had a medium/high moisture content, we recommended a semi-wet preparation process.
A Client from Belarus who always worked with a disintegrator mill in his Brick plant, was unsatisfied with its clay preparation degree, as it did not allow them to produce big formats and thick-wall products.
