In 2007, Hunger Maschinen GmbH supplied Thyssen-Krupp Fördertechnik with power units for a fully automatic coal crusher located in Yimin He (Inner Mongolia), China. A hydraulic drive station with a drive capacity of P = 2 x 250 kW and a total output capacity of Q = 1050 l/min powered a crusher conveyor drive, 1 hydraulic power pack for the crusher discharge boom, 4 hydraulic power packs for the conveyor plant, 1 hydraulic power pack for the double roll crusher, as well as 4 control blocks for the transport crawler.
Under the most demanding climatic conditions, the plant mines approximately 3000 tonnes of coal per hour in China's northernmost open pit mine. As a result of the double roll crushers, the plant is ideally suited to crush loose rock and bedrock that can withstand pressures of up to 180 MPa. In addition to coal, other minerals such as: rocks and soil, natural stones, slags and cement clinker can be mined with this crusher.
