Grinding and drying of bentonite
After crushing and drying mined bentonite, this clay mineral is usually processed through a grinding mill into powder form. To maximize the capability of bentonite powder in hydration and water absorption, a combined milling and drying system with a higher lifetime of wearing parts is required to achieve desired fineness and product quality.
