Difference Between Ball Mill and Rod Mill Rod Mills. The principal field of rod mill usage is the preparation of products in the 5 mm— mm (4 mesh to 35 mesh) range. It may sometimes be recommended also for finer grinding. Within these limits a rod mill is usually superior to and more efficient than a ball mill. The basic principle for rod ...

Plastic sheeting is measured in mils. A mil is a measurement that equals onethouh of an inch, or inch. One mil also equals mm (millimeter). Thus a mil is not the same thickness as a millimeter. The term "mil" is not an abbreviation but a unit of chart below gives you an idea of mils to millimeters to inches.

Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft.. Thus, quantitatively, less material can progress through the voids in the rod mill grinding media than in the ball mill, and the path of the material is more confined. This grinding action restricts the volume of feed which passes ...
