Proposed dry grinding process with precooled parts Many grinding processes are not critical to grinding burn and could be performed dry if the temperature rise in the workpiece would not be so high. Precooling the material is being researched in the cutting of biological or soft materials and also for the avoidance of dust [11], [12] .

CONTINUOUS OR BATCH GRINDING PROCESS? Batch dry grinding is employed when the material requires longer residence time (over 30 min and more), and the prime consideration is the finest particle size possible, tighter distribution. Another important reason for choosing batch grinding is ability to control the milling atmosphere. The grinding tank

Wet Grinding vs. Dry Grinding, what is the advantage of both of them? The process of wet or dry grinding is used to reduce particle size in order for particles to be more easily dispersed into liquids. The benefits of using this method are that it allows for greater control over the final product as well as less energy consumption than other methods such as hammer milling.
