Coating/Lagging

A distinction is made between hot vulcanised and cold vulcanised coating. Hot vulcanisation is a process in which the shell is wrapped in thin layers of rubber and then ‘baked’ in an autoclave to form a seamless lining. It is possible to provide profiled lagging to drive the belts. Cold vulcanised means that the lagging is glued around the motor.

Common types of coating or lagging include:

 

Hot vulcanised lagging

This lagging is available in any desired thickness and profile. The standard hardness is about 65 degrees shore, but other hardnesses are available on request. Available in black, white and blue.

ETR

Cold vulcanised rubber with a diamond profile, 65 degrees shore hardness, available in 6, 8 and 10 millimeters thickness. Standard in black, 8 millimeter thick is also available in white and blue, the hardness then changes to 55 degrees shore. (Foodgrade, for food processing)

Laminop

Cold vulcanised Nonex PVC with a studded profile, hardness 50 degrees shore, 3 millimeters thick. Available in white.

Lamiglad

Cold vulcanised Nonex PVC without profile, hardness 55 degrees shore, 2 millimeters thick. Available in white and blue.

Lamirib

Cold vulcanised Nonex PVC with a rib across the belt, hardness 55 degrees shore, 5 millimeters thick. Available in blue.

NA 55

Cold vulcanised Nonex PVC, smooth or with a rib across the belt, hardness 55 degrees shore, available in 6 and 8 millimetres. Oil and grease resistant. Available in white.

Sprockets

Are you looking for a drum motor to drive modular belts? Van der Graaf are the specialists to call. The drum motor will be provided with a cylindrical shell (special) for solid mounting of the sprockets. For some types of conveyor belts, the shell can also be provided directly with the required profile.
