Electrostatic charge in the conveyor belt may be caused by friction between the belt and the slider bed and/or the movement of the conveyed product or due to ionisation of the air (dry and dusty atmospheres). Although the static current is usually of low intensity, it can be the cause of problems for example when light pieces of product stay adhered to the topcover of the belt. In cases where there is risk of sparks, it could also be hazardous in environments sensitive to deflagration.
To prevent this problem, Paradise has developed a series of conveyor belts where certain components have been added to allow the characteristics of the belt to be changed to a form which instead of accumulating the static current, drives or directs it to the chassis of the conveyor.
The standard that currently regulates the measurement of surface electrical resistance is the ISO 284. Paradise has a wide range of antistatic belts, for use with both horizontal conveyors and bucket elevators.
There are different anti-static levels or grades pertaining to the components cited below:
