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.

Ball Mills. Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to <200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation. Sold individually or as part of our turnkey ...

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

A white metal bearing is essentially a composite bearing. Hard crystals are dispersed throughout a softer metal. As the bearing wears, the softer areas erode and create paths and pockets for the lubricant. The softer material also protects the bearing from damage caused by abrasive particles. Since the bearing is relatively soft, abrasive ...

This is provided by a high pressure oil pump which delivers oil between the bearing and journal. The oil, injected under pressure, lifts the mill and helps to reduce the friction between the shoe and ring, providing alignment. The minimum oil viscosity for most mills is 44 cSt at 100°C and typically requires an oil with an ISO 460 Cst viscosity.
