Dry Magnetic Saperation Of Coal

Magnetic separation of raw coal and semicoke grinded up to particle size 0–0.5 mm was conducted in a laboratory magnetic separator in two steps—the first was at magnetic field induction of 0.35 T, the second—at 1.7 T.

Our crushers are designed and built with advanced technology and stringent quality control at every stage of the manufacturing process, to meet the rigorous demands of aggregate operations.Our #1 goal is making the customer more productive and profitable by providing the best impactor-based technology and after-market support available.
