Double Roller Crusher: FAQ

Q: How does the double roller crusher handle wet coal without clogging, and how does it reduce waste fines?

Double Roller Crusher

A: Unlike traditional impact crushers that rely on internal screens (which easily blind with moisture), the double roller crusher utilizes a continuous low-speed static pressure extrusion mechanism.

Wet coal is drawn down and forced through the roller gap instantly, eliminating material buildup and sticky clogging. Furthermore, by pressing materials along their natural fractures rather than shattering them repeatedly, it controls the over-crushing rate (fine dust under 3mm) to less than 5%, maximizing your high-premium coal output.
