Method for preventing dust penetration into supporting roller's bearing of belt conveyor, involves forming overpressure of gas within rollers during conveyor operation and after adjustment and interruption operation up to cooling rollers

摘要

The method involves forming overpressure of gas i.e. air, within supporting rollers during operation of a belt conveyor and after adjustment and interruption of the operation up to cooling the rollers. The overpressure of the gas is formed before adjusting or interruption of the operation of the belt conveyor up to the rollers. The gas is inwardly guided to a housing (1) of the rollers by a compressed air line (2) during operation of the conveyor, where the compressed air line is connected with a channel (3) of an axle (6) by a pressurized air clutch (8).
