Usually an A-frame type of head pulley support, with one leg vertical, provides better access than a table frame design. Recommendation: Test the bulk solid and use the properties that represent the worst-case flow to design the chute using DEM. Design the structure so that it does not impede access to critical components, yet allows adequate ...

The new design, proposed by CDI, replaced the rock box with a curved chute design. The angled back wall of the curved chute reduces the material's free fall distance by interdicting the material flow closer to the head pulley. In addition to helping control and center the material, this feature results in a lower impact angle and velocity at the

The ordinary head is mainly used for small belt conveyor, the snub head frame increases the support for the snub pulley, and the double pulley head frame is used for large conveyor. The intermediate frame is divided into standard and non-standard ones, with standard length of 6000 mm and non-standard length of 3000-6000 mm.

Douglas® Truck Tire Tuff™ Conveyor Pulley Lagging delivers increased traction and pulley life over non lagged pulleys. Increased traction between the pulley face and the belt bottom cover reduces belt slippage and helps to improve belt tracking. Vulcanized rubber lagging protects the pulley's face from wear and extends pulley service life.
