A descriptive Explanation of the Belt Tracking Properties of Pulleys by using the geometric Properties of the flat Pattern of their Surface

By G.A. Kribitz The direction of a conveyor belt is changed, at pulleys, according to the wrap angle between the pulley and the belt. Compared with idler rollers which just support a conveyor belt, pulleys, due to the wrapping belt, provide different opportunities concerning belt tracking. Due to relatively high belt tensions and wrap angles combined with the according friction factors, pulleys mainly provide static friction to the conveyor belt at the ongoing side [1]. There are different hypotheses available in literature for the explanation of belt tracking and belt misalignment effects concerning pulleys, but apparently none seems to be accepted to be generally valid.

New ABB Drive Solution significantly decreases the Cost Threshold for Gearless Conveyor Technology

Zurich, SwitzerlandABB‘s gearless conveyor drive is now available for use on a wider range of conveyor systems. Already proven on larger motors, the newest drive is designed for medium power range motors (1 to 3 MW per motor) to make this technology economically feasible for a broader range of conveyor systems, including the use on mobile equipment in mining operations. The new solution can be applied for both greenfield and brownfield systems, and significantly decreases the cost threshold for gearless conveyor technology. Continue reading New ABB Drive Solution significantly decreases the Cost Threshold for Gearless Conveyor Technology

Flexco TUG HD Belt Clamp simplifies Maintenance Work on Conveyor Belts

Rosenfeld, Germany – When a conveyor belt is stopped for maintenance, say in a coal mine, its own weight can create problems by distributing the tension unevenly. To ensure that a belt can be safely cut and securely spliced by service technicians, the forces in the area under repair should be spread over the whole width. For this purpose Flexco has developed the TUG HD belt clamp. It is suitable for a variety of materials and belt types – and meets rigorous industry standards.
