Since their first Rulmeca Motorized Pulley purchase, Inertia Machine and their customers obtained significant benefits from the internally powered drives and standardized on the compact drives to power key conveyors.

Inertia Machine's 5066 Tracker features Rulmeca Motorized Pulley model 400M at 15 hp to move up to 700 tph of crushed product at 300 fpm, using 460v/3ph/60Hz.

As shown here, Inertia’s 5066 Tracker uses a 15 hp Rulmeca Motorized Pulley to drive the 42-inch rear discharge conveyor. This belt transfers up to 700 tph of shot rock limestone, recycled asphalt and recycled concrete at 300 fpm from the huge horizontal shaft impact crusher to the discharge point. Initially selected because of their compactness, the Rulmeca Motorized Pulley quickly demonstrated its high efficiency and robustness when the discharge conveyor plugged during commissioning. “We pulled off a couple two foot chunks of concrete and then fired up the conveyor,” said Tyler Burkholder, Inertia design engineer, “and were surprised that the drive dug itself out without tripping.” He explained that the motor/gearbox/V-belt drives used previously were prone to tripping under those conditions. In addition to the powerful crusher, plant compactness and portability are key features of the 5066 Tracker. Note that it is the only tracked plant of its size capable of being transported from pit to pit without disassembly.

Off site transport preparation is limited to inserting a triple axle bogey into the kingpin beneath the discharge conveyor and hitching a triple axle semi truck to the kingpin beneath the feeder, as shown. Rulmeca’s compact and powerful conveyor drive is a natural fit with Inertia’s plant design strategy. Burkholder said, “Rulmeca Motorized Pulleys reduced our assembly time and enabled us to stay with electric power.”

Rulmeca Motorized Pulley usage recently expanded when Inertia recently included 10 and 15 hp units into the company’s 4048 closed circuit plant, currently under construction, driving the 100 tph closed circuit and 300 tph delivery conveyors, respectively.

Since the plant features quick and easy set up to process RAP, Motorized Pulleys were selected. “These drives give us a great alternative conveyor drive to expand our product line and stay with electric power,” said Inertia’s Burkholder. Initially developed in 1953 for coal and stone conveyors in fixed plants in Europe, Rulmeca Motorized Pulleys have gained acceptance in portable plant usage throughout the world. Now portable plant operators can enjoy higher system reliability and lower maintenance expense because Rulmeca Pulleys enclose all drive components within an oil filled hermetically sealed pulley shell. Rather than struggling to protect exposed conveyor drive components, portable plant operators who use Motorized Pulleys can hide them out of harm’s way when handling stone, RAP and recycled concrete. Rulmeca president Mike Gawinski said, “We’re very pleased to supply Motorized Pulleys for Inertia’s 5066 Tracker and 4048 FRAP plants. We’re sure their customers will be very pleased to use them.” To comment on this story or for additional details click on the related button above. |
