Food Grade (Hygienic) As Per International Standards These belts with white rubber covers do not impart odour and do not stain the materials to be conveyed and thus are particularly suitable for food processing and pharmaceuticals industries. These belts are manufactured with FDA approved polymers and are available in high abrasion resistant / antistatic / oil resistant cover grades.

OR As Per International Standards Carrying parts and components coated with machine oil & other oily materials. NN, EP

Rough Top As Per International Standards These belts are specially designed with a Rough Top / Pimpled or Ribbed / Cleated carrying surface to prevent slippage. Ideally suited to carry packaged materials on gradients of more than 20º. Low friction co-efficient with bare back bottom. Two or three plies of synthetic fabrics provide high strength & flexibility.

The rubber cover should be selected by taking into account the type of material to be handled and the operating condition of the belt. Conveyor belting is available in the following grades and ranging from 150 mm to 1500 mm with Moulded edge “ME” construction for Cotton belts and Cut edge construction “CE” for Nylon & EP belts in open or endless lengths.

SHR Heat and abrasion resistant
lump 150o C (max)
fines 125o C (max) IS 1891(Part II) Best for general hot materials and services such as steel clinker, hot sintered ores, steel pallets and others. NN, EP

Load transmission capacity of belt is directly proportional to its speed. Large diameter pulleys with increased surface speed and consequently high load capacity (of the belts), gives a greater safety to the outer plies of the belts from the effect of excessive stress and also help to regulate the load throughout the cross section of the belt.
