    Rulmeca Corporation Motorized Pulleys & Variable Frequency Drives

    January 16, 2004, Wilmington, North Carolina- Rulmeca Corporation announced the successful application of Rulmeca Motorized Pulleys in several significant bulk materials handling applications with Variable Frequency Drives (VFD.) Rulmeca Corporation President, Mike Gawinski, said “These applications prove that plant operators can reliably vary conveyor speeds using three phase AC electric power and Motorized Pulley-VFD technology… even in harsh operating conditions.”

    Limestone Quarry (USA)
    Two 15.75” diameter 5.5 HP Rulmeca Motorized Pulleys were installed 1994 to automatically “choke feed” tertiary gyratory crushers, working in combination with variable frequency drives and optical sensors, to optimize product size and throughput rate. Each pulley drives a 36” wide belt at a maximum speed of 120 FPM to transfer 4” minus product at 425 TPH.

    After testing the “automatic choke feed” concept in 1994 and 1995, this national aggregate producer incorporated Motorized Pulley-driven hopper feeder conveyors at five additional quarries in the US.

    Minerals Processing Plant (USA).
    Two limestone feeder belt drives beneath storage silo were converted from 20-year old DC motors to AC-powered motorized pulleys in 1995. A VFD drives each 19.72” diameter 5.5 HP motorized pulley to a maximum of 120 FPM. Conversion enabled plant operator to eliminate exposed motors and gearboxes and replace SCRs, relays, and timer banks with VFDs in control panel.
