When traditional hammer or impact crushers process wet coal gangue, fine particles quickly adhere to the crushing chamber and screen plates, leading to frequent shutdowns for cleaning.
Double Tooth Roller Crusher
The Huashengming Double Tooth Roll Crusher operates on a low‑speed, high‑torque shearing principle. The two toothed rolls rotate at differential speeds, tearing and squeezing the coal gangue instead of impacting it. The self‑cleaning tooth geometry allows wet fines to fall away naturally – no clogging even at 30% moisture. The shear‑dominated action keeps fine powder below 15%, effectively preserving the integrity of pyrite particles in the gangue and significantly improving downstream jigging or flotation recovery.
