One of our Ball Mills keeps losing pressure on the high pressure pump. It will run fine when starting the Mill and suddenly after a while sometimes 1hrs the pumps will loose pressure. We have just grinded the journal and installed new white metal bearings. After startup this afternoon after about 1hrs the pumps low and high just lost pressure.

The final product from these large regrind ball mills using small grinding media will be approximately 28 microns. The mills will produce a fine ore stream which enters magnetic separators to become a concentrate. The concentrate will be thickened and stored before being pumped 25 kilometers to the port, where it is filtered to reduce moisture.

For one, the ball charge and tumbling motion of a Bond mill is inefficient in this range. Also, screening well at 500 mesh is not easy. Many people overlook the impact of screening on the Bond results but the impact can be significant. The other issue is that nowadays fine grinding is not performed in tumbling mills for energy efficiency reasons.

used. Tower mills were first introduced in the 1950s as an alternative to the ball mills in a regrinding application. Since then they have been used to grind a range of materials from limestone to coal to sulphide concentrates. A Tower mill can be installed for a fraction of the cost of an equivalent kilowatt ball mill.

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.
