Mill Bolting. 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.

Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless .
