A global conveyor supplier required torque overload protection on screw conveyors used at a power plant in Indonesia. The conveyors move waste material, provided by local suppliers, to and from the facility’s furnaces. The unmonitored material being transferred often contains large pieces of steel and concrete that could cause jams and possibly damage the conveyor’s screw element.
Drives and motors are used to power an array of equipment in mining operations, from conveyors, and crushing/grinding equipment to flotation cells and pumps. The major challenges associated with powering mining equipment is the increased scale of operations and the accompanying requirement for increased power, whilst maintaining reliability. There are a range of companies that provide drives and motors for the mining industry, some of which are mining specific whilst others cover a range of industries.
