Cement and mining industry

Cement and mining industry

Large infrastructure projects in the “boom regions“ are leading to a strongly growing demand for building materials such as cement, steel and non-ferrous metals which in turn results in a constant demand for an increase in efficiency for the development and processing procedures in view of finite resources. The mining industry is also developing rapidly at present, since the supply of iron and non-iron ores in sufficient quantities is a requirement for the production of various final products.

Large amounts of these resources are broken, milled, transported, sighted and burned; dust, heat and mechanical loading leads to high requirements on the motors which VEM supplies for crushers, mills, fans, furnaces or conveyor plants.

Asynchronous motors with slip-ring rotors are especially suitable for the heavy start-up conditions for mills and crushers under full load and for fans with very large mass-moments of inertia. Cooling takes place primarily with air-to-air heat exchangers and separate ventilation of the slip ring area.
