Nanometer materials are widely used in a variety of applications because of their improved properties and reduction in consumption. Generally, materials can be ground into a nano-scale by wet grinding and dry grinding. But you are probably wondering what the difference is between wet and dry grinding.
In wet grinding, water or the other liquid additive can serve as a lubricant to reduce friction and it also absorbs heat generated during grinding to minimize the risk of melting the resin or coating of the tooling. A surfactant can be added to the grinder to prevent the ground particles form re-agglomerating, which means better grinding effects than dry grinding.
In industrial production, wet grinding is preferred because it is power saving, which means more materials can be ground with less energy. It is also more cost effective than dry grinding that may produce a large amount of dust that requires additional effort and equipment to remove.
However, wet grinding is not suitable for grinding all materials. Dry grinding is the more economical choice for materials with less demanding size requirements or those affected by water. You are welcome to contact us to discuss how to improve your grinding effects.
