The drum spiral conveyors transform the dynamic friction strength, existing between the belt and the powered drum, from a dissipative type force to a conservative one . The driving shaft placed on the rectilinear stretch going our from the spiral, connected to the motorized gearbox named “master” , moves the belt.
Therefore, the drum, a cylindric-shape stainless steel structure placed inside the spiral center and on which the belt is wrapped, uses the friction strength generated to move forward the belt to the movement direction. In this case the belt is in stainless steel mesh considering the product dimensions and production quantity .
The advantage of this type of machine, is in the overall dimension that, thank to very reduced space among the tiers, allow to get much smaller dimensions and very high movement speeds.
