As a general rule, there should be less than 25% of clinker that is below 1mm in size. Coarse clinker is more of an issue for ball mills. Some cement groups use a formula, such as Bond's, to calculate the maximum ball size required in a ball mill, based on the average size of the clinker feed. However, one drawback with this approach is that ...

Grinding is an ageold technique of particle size reduction to produce powders that can be used as intermediate or end products. Grinding aims to reduce the size of the particle by mechanical means such as impact, compression, shear, and cutting (Sahay and Singh, 1996).Hammer mill, plate mill, ball mill, pin mill, roller mill are commonly used grinding equipment for spice (Balasubramanian et ...
Grinding dust becomes airborne causing harmful health side effects to operators and nearby employees. Metal grinding dust turns respirable when broken up into particles 5 microns in size. These microscopic sized particles enter and deposit deep within the lungs leading to impaired lung functioning and possible lung disease.
