The attritor mill is a versatile machine that can be used for both wet and dry grinding. In wet grinding, the material to be ground is introduced into the milling chamber along with a liquid such as water or a solvent. The liquid serves to reduce the viscosity of the material and helps to disperse it evenly throughout the milling chamber.

Wet ball milling has several advantages over dry ball milling. Let's explore some of them: 1. Better Grinding Efficiency. The liquid in wet ball milling acts as a lubricant, reducing friction and improving the grinding efficiency. The particles are more effectively ground and dispersed, resulting in a finer particle size distribution.
