Mining & Mineral Processing

Reliable and Long-lasting Conveyor Belt Drives

Improves Conveyor Reliability
Since 1952, the Rulmeca Motorized Pulley has been a reliable mining and mineral processing conveyor drive. The hermetic seals and continuous oil bath of all bearings and gears insure that the drive provides consistent “up time” in spite of abrasive, corrosive, hot, or cold operating conditions.

Lowers Maintenance Expense
The Rulmeca Motorized Pulley eliminates external bearings, which require greasing and inspection. Instead, it encloses all mechanical parts within an oil-filled hermetically-sealed shell, reducing maintenance requirements to a fraction of what exposed drive systems require.

Reduces Energy Consumption
Rulmeca Motorized Pulleys require less than 90% of the electrical power of exposed drive systems when compared with motor/reducer/chain & sprocket or motor/reducer/V-belt drive configurations.

Improves Quality of Work Environment
Retrofitting old exposed conveyor drives with Rulmeca drives has enabled some operators to reduce plant sound level and eliminate complaints about noise. One mine reported a 15 decibel sound level reduction after replacing their exposed drive with a 100 HP Rulmeca Motorized Pulley.

Makes Installation Easier
Since the Rulmeca Motorized Pulley is compact, pre-aligned, and often 35% lighter than an equivalent exposed drive, installation is easier and quicker, usually 1 to 2 hours. Setting heavy external gearboxes and motor frames and laser-aligning shafts and couplings are eliminated.

Improves Personnel Safety
The Rulmeca Motorized Pulley protects plant personnel from pinch points as well as slip, trip, and fall hazards because it encloses all moving mechanical parts within a pulley shell . The drive eliminates the need for expanded metal guarding around rotating shafts, external gearboxes, motors, and cooling fans.
