1972-6-61. The method of starting the operation of a belt conveyor comprising the steps of energiing a high slip start-up motor substantially simultaneously with said energiing, accelerating said conveyor by rotational torque delivered thereto by the energied startup motor substantially simultaneously with said energiing, rotating a rotor of a low slip, single speed, main motor by rotational

The low starting currents and high starting torque enable smooth startup of the conveyor, even when it is fully loaded. 4. Low-speed operation for belt inspection. For maintenance inspection about belt changes and repairs, it is possible to run the conveyor belt at low speed. Fig.2 Conveyors in sugar factory. Fig.3 INVT VFDs for conveyors

Belt Conveyors are also a great option to move products through elevations. Incline Belt Conveyors from low to high and Decline Belt Conveyors from high to low. This manual is short with quick and easy reading paragraphs very practical for calculations of belt chain conveyors and mechanical miscellaneous in the metric and imperial system

Starting and braking curves, horiontal turning, and broken band detection of belt conveyors were studied in the Liaoning Technical University using finite element analysis 12, 13. A model of the whole belt conveyor was established using the discrete dynamic method and dynamic simulation software was constructed at Northeastern University

Scraper chain conveyors. Scraper chain conveyors must be able to start up in any load condition, which is easily ensured with the high starting torque delivered by our drive solutions. Our drive systems can start and stop as frequently as needed, without the risk of
