CPE Lesson 30. Belt Conveyor

The type of idlers affects the cross-sectional load on the belt. Flat belt idlers are used for granular materials having an angle of repose of not less than 35 °. Flat belt idlers are preferred for low capacity requirements. Toughing idlers with 20 ° through are used for conveuying all kinds of bulk materials.

Material spillage can occur when conveyor belts become misaligned. Strategically placing self-training idlers along the conveyor keep the belt running true. s self-trainers are like troughing idlers but with the ability to pivot at the center and are guided by edge rollers which in turn aligns the belt.

Types Of Gears Material Used For Gears Application

Types of Gears A number of gears are manufactured using different materials and with different performance specifications depending on the industrial application. These gears are available in a range of capacities sizes and speed ratios but the main function is to convert the input of a prime mover into an output with high torque and low RPM.
