SBM Concentrate equipments are designed for continuous 24 hour per day operation in chemical, industrial mineral and ore processing industries. Units are supplied in two basic conﬁ gurations: bridge or centre pier mounted in diameters from 5 to 75 m.
For bridge mounted drive heads rake lift is through a torque tower which is bolted to the main wheel and drives the rake shaft through a keyway. The rake shaft is raised and lowered by a motor driven screw jack.
Operating torques are continually monitored.
A motor torque sensing device which accurately measures the motor power, provides preset overload outputs, rake lift, warning, and shutdown.
The lift mechanism is fully auto matic and is activated by the torque sensing system.
All controls are located in a weather proof enclosure mounted on the bridge. Rake torque is locally displayed and automatic - local operation can be selected for drive and lift motors.
