Generally speaking, the finished product size below 1500 mesh is generally produced by dry grinding process. For product size from 1500 to 2500 mesh can be produced by dry gridning process or wet gridning process. For products from 2500 to 6500 mesh, wet grinding process is usually appropriate for production. Ground calcium …

Introduction. The efficiency of most grinding processes which are performed wet or dry is very low. Dry grinding, in particular, is a difficult process in terms of material transportation since the particles are prone to form agglomerates and coating on the media and mill liners due to the static forces that occur during the grinding operation [1].
