Full definition
Inclination angle of lateral idlers relative to the horizontal in a troughing idler station. Standard angles per CEMA/DIN 22102: 20°, 35°, and 45°. Higher angles increase volumetric capacity and better contain the material. The 35° angle is most common in mining and heavy industry; 45° is used for fine or high-capacity materials. Directly affects cross-sectional area calculation and conveyor drive power requirements.
