Coal & Mining Conveyor Rollers | Bulk Handling Systems

Opening Remarks. The original concept of the prefabricated ball bearing assembly (cartridge), for welded steel conveyor rollers, was developed by Edwin Lowe Ltd during the mid 1980's – based upon the requirements of the state owned company British Coal – for use within rollers in the underground and above ground bulk handling systems – then used by British Coal here in the …
