Mineral dryers for heavy-duty processing
Mineral dryers need to be designed for heavy duty processing. Sanding and eroding – such is the reality of the drying processes of coarse-grained minerals, like sand, and gravel. Also, mineral drying is a critical step in total production process. When drying large volumes of material, energy consumption is the greatest controllable expense.
