CHEVRON CONVEYOR BELTS


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, SAVA 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 crushers and screens

chevron conveyor belts



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

Type of material Material example Max. angle of inclination
Height of cleats
h(mm): 16 h(mm): 25 h(mm): 32
POWDERY Flour, lime etc. 25° 28° 30°
LOOSE FLOWING Grains: corn, barley, wheat, rye, dray sand 20/25° 25/30° 25/30°
LOOSE ROLLING Gravel, ground stone 25° 28° 30°
STICY Wet sand, ash, wet loam 30/35° 35/40° 40/45°
PACKED Sacks, jute sacks, paper sacks 30/35° 35/40° 35/40°

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

Mass flow:
Qm = Qv . ρ   t/h
