Application fields

The ball mills, (tubular or double-cone-shaped) are the most suitable machines for grinding very abrasive raw materials as minerals, silica sand, feldspar, because of their simple, low cost and reliable way of working.
For ordinary types of grinding work, mills are supplied with manganese steel or Ni-Hard cast iron linings, and with balls or chilpebs also in manganese steel or Ni-Hard cast iron as grinding media.
Where it is desired to obtain ground products that are entirely free of traces of iron, mills are supplied with linings in silica, steatite, alumina or porcelain, and with silica pebbles, or balls of steatite or alumina as grinding media.
These mills may be constructed and used for dry or for wet grinding. Those suitable for dry grinding can operate in a closed cycle with an air separator or an air conveying system. Heating can be supplied when wet products are to be ground.
Raw material feed and ground product discharge are continuously operated.
