Conveyor belts with a smooth carrying surface are useful for conveying of packed and

unpacked material up to the angle of inclination 22° as an upper limit.

CHEVRON belts are the right belts to meet your requirements when higher angles of

inclination are required.

For this purpose, Brindavan Udyog (India) has developed high-performance and high-quality

Chevron and High-Chevron conveyor belts. Their advantages are long service life and flexibility

due to homogeneous Chevron profiles which are vulcanised together with a base belt.

Areas of Application:

Quarries, sandpits

Cement works, lime works

Farming: conveying of beets, grains, potatoes, fertilizers, wooden chips, coal and coke transport

Sugar refineries

Salt mines

Mobile crushes and screens

Selection of a type and height of profiles depends on the material to be conveyed and

the angle of inclination:

The values given are just an orientation and depend on the type of goods conveyed, loading conditions and the conveyor belt speed.

The maximum inclination of a smooth conveyor belt reaches from 15° to 22° in dependence of

the type of material.

Steep angle conveyor belts with a profiled surface reach an inclination of 30° to

over 40°. In unfavorable loading conditions only the profiled surface may be

loaded.

For the rest, the capacity is calculated in the same way as for smooth surface conveyor belts.

Equations: Volume flow: Qv = Qth . k . v m3/h

Qm = Qv . ρ t/h
