The Chinese mining operator XinJiang TianChi Energy Co. has placed an order with thyssenkrupp Industrial Solutions to supply four RollSizers for the secondary crushing of coal. XinJiang TianChi operates a number of coal mines in the XinJiang region and opted for RollSizers with 2×315 kW drive power and throughputs of up to 2,000 tons per hour. The four DRS 660 x 3700 S RollSizers from thyssenkrupp’s recently established standard machine line are designed as SideSizers and crush coal with a feed size of up to 300 mm to a finished product size of 50 mm. The processed coal will mainly be used for power generation and heating.
