 — The ball mill was tested as a grate discharge mill and as an air-swept mill. Feldspar was chosen for the tests. The grinding process was also studied in connection with production of materials in ...

Single Pass Air System: With a single pass air system, air is drawn into the mill base, travels through the classifier, bag filter and fan and is then vented out to atmosphere. In addition to being dust free, the air swept grinding zone prevents over-grinding by the air stream lifting the particles of certain sizes out of the grinding zone.
