In many grinding plants mills which have metallic or rubber liners suffer from bolt breakage. Our technicians come across broken mill bolts at many sites around the world, to the operators of the mills it is an almost normal occurrence, but if you have breaking bolts there is an underlying problem which needs to be fixed.

In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill & ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.

Dec 12, 2003· However, a ball cutter can perform well in these applications, too. For example, I would machine a deep slot, whether open-ended or closed, by using a ballnose tool along with shallow ramp and Z-level milling techniques typical of high speed machining. The slot could be produced much faster this way than through milling with a cylindrical end mill.
