The new Grasan tracked belt feeder is designed for short travel from face to conveyor belt lines in quarries and sand/gravel operations.
It has a 30-yard hopper capacity and can feed up to 1,500 tons per hour. This new model was designed for large sand/gravel producers to eliminate the need for haul trucks.
The 130,000-pound, extra heavy-duty unit is powered by a high-torque, variable-speed electro-hydraulic motor to provide greater durability, speed ratio capabilities and starting torque capacity. The hydraulic motor is small, light, requires less maintenance, and uses less electric power than a gear-box drive. Also, it is not sensitive to harsh environments and has unlimited shock load capacity.
The feeder is equipped with E7 idlers and ceramic lag head pulley. Four independent hydraulic legs provide operational support during belt feeding. Remote pendant control is standard, yet the unit can be programmed for automatic operation from a control tower or other location.
