The increased metal wear of grinding media and mill liners for wet grinding equalizes the additional energy costs of the dry grinding procedure. When dry grinding cement raw material, a protective coating of ground material covers the mill liners and grinding balls. It is known that cement raw material is much less abrasive than cement clinker.
A ball grinding mill consists of a hollow cylindrical shell that is partially filled with balls. The grinding media is the steel balls that can reduce the size of materials to a fine powder. Grinding can be carried out either wet or dry for various ores and other materials.
The raw mill will be operate with a much coarser ball charge than the cement mill mainly because of the bigger slot sizes of the partition wall. The transition zone consists of 50 mm and 60 mm balls. The basis is a 50 mm ball size for 5% residue on the 4 mm sieve. In case bigger grains are by-passing the partition through the center grate even ...

The better mills on the market have an efficiency of about 8-9 % which means that only 8-9 % of the energy results in grinding and the majority is converted mainly into heat. The ball mill has the worst efficiency of all types of mills on the market. Just 4 % of the energy is used for comminution. Nevertheless when grinding is required the ball ...
It is mainly used to grind limestone, clay, and other cement raw materials, as well as calcined clinker.

What is a Ball Mill? A ball mill is a type of grinder that uses metal balls or other grinding mediums to reduce the size of various materials. The material to be ground is placed in a cylindrical container that spins on its axis. The metal balls or grinding media inside the container hits the material and breaks it down into smaller particles.
To ensure long-lasting operation, we build the STANEX diaphragm from materials that can stand up to the high-wear conditions of a ball mill. The grates are made of a highly ductile and wear-resistant heat-treated alloy steel, while the lining plates facing the fine grinding compartment are made of 50mm thick heat-treated alloy steel.
