Lagging

Van der Graaf can fit your drummotor with different kinds of lagging. The power produced by the drummotor has to be transferred to the belt and lagging is used to give more friction between the drummotor and the conveyor belt.

There is a difference between cold and hot vulcanised lagging. Cold vulcanised means the lagging is glued to the drummotor usually in sheet form and the join 'welded' together. Hot vulcanising is a process where the shell is wrapped around with thin layers of rubber. The shell with the rubber is then baked in an autoclave fusing the layers together creating a seamless finish.

It is possible to cut grooves (e.g chevron or diamond) in the lagging.
