Project details


The conveyor drive area of the Sandwich Belt high angle conveyor is restricted. Therefore, DSI chose two model 320H Rulmeca Motorized Pulleys, each with a 5.5 HP electric motor and 76 fpm nominal belt speed on a 380v/3ph/50Hz power supply, to drive the two Sandwich Belts. Providingthe belt tension required to move the load from the discharge point, each RMP was outfitted with a counter clockwise mechanical backstop to prevent material dropping when the motor is de-energized.



Key factors in the selection of Rulmeca Motorized Pulleys were: • Compact size • Light weight • High reliability • Personnel safety • Ease of maintenance


We worked with DSI engineers from the start of the design process to verify that two compactmodel 320 Rulmeca Motorized Pulleys, controlled by load-sharing VFDs, would be the best fit for the application while providing adequate power to move the required material handling rate specified by SNF Coagulants.
