Here are some of the materials used as grinding media and their respective applications: 1. Alumina Alumina media is one of the most commonly used grinding media today. It is available as satellites, rod/cylinders, and beads. In general, alumina media are used in high-profile industrial milling processes.
Through- feed grinding. In through feed grinding, workpiece will be feed axially by the axial force exerted on workpiece and this axial force will be applied by rotating surface of regulating wheel. Through feed grinding process is considered as quite productive as grinding process could be performed simultaneously for number of objects.

two different processes are generally performed in the grinding. mill. The heat required for drying the raw material is supplied by. hot gases from preheater or cooler or hot air generator and by the. heat generated by comminution in the grinding process. In ball mills for drying of raw material a drying compartment is.
Raw mill is mainly used in grinding raw materials and end products in cement plant. It is also suitable for various ores and other materials metallurgy, mine, chemical and construction. Besides, it has two forms of milling, one is an open form, and the other is a recycle close form…----_
CERAMIC MATERIALS IMu. During grinding usually in water, the ore is ground from a maximum 20 mm diameter down to about 0.3 mm or less The comminution process remains inherently inefficient. 85% of the energy used is dissipated as heat, 12% is attributed to mechanical losses and only 1% of the total energy input is used in size reduction of feed material.
