In the "wet" process, the ground materials are first mixed with water to form a slurry before being fed into the kiln. The use of the dry process for cement production has increased significantly in the last couple of decades (Figure 1), partially due to the lower fuel requirements for the dry process (discussed further below). In 1975, dry

When it comes to effective particle separation, gravity separation is traditionally done as a wet process rather than a dry process. In fact, wet processing has been the industry standard across the mining industry for centuries, and has recently been adapted into urban mining processes such as incinerator bottom ash separation. There is a reason wet processing is the optimal choice for ...
