Single roll slag crusher

single roll slag crusher

The single roller slag crusher is a special crushing equipment for the coal-fired boiler slag removal system, which is used to crush the slag discharged from the dry slag machine into less than 25mm and send it into the slag bunker.

The equipment consists of a drive mechanism (featuring a motor, hydraulic coupling/coupling, and reducer), main body, base frame, and electrical control cabinet, offering three transmission modes: chain drive, direct drive, and shaft-mounted drive. The hydraulic coupling is designed for wet slag removal systems, while the coupling is primarily used in dry systems. The crushing body adopts a full-tooth, spaced-tooth plate, or gear ring structure, equipped with an interlocking canine-toothed crushing tooth design. The increased tooth height and alternating spacing enhance particle size reduction and crushing force. The electrical control system supports automatic reverse rotation for slag jamming and shutdown protection, performing three forward/reverse rotation attempts when encountering resistance, with an alarm triggering shutdown upon failure. For mechanical protection, the hydraulic coupling provides oil discharge to protect the motor, and the coupling incorporates a breakable nylon rod for overload protection. Some models feature adjustable stationary jaw spacing, optimizing crushing clearance through bolts and slag plates.
