Rubber metal pulp lifters are necessary for mills, which strengthen grinding effects and improve efficiency. Rubber lifter bars for grinding machine can be used for 36 months, while the metal ones are 12 months. Made of rubber material, they are much lighter and anti-corrosion. Rubber metal pulp lifters are suitable for AG mills, SAG mills and Primary Ball Mills. The rubber metal pulp lifters are manufactured with specially hand laid rubber on the metal structure and easily retrofit onto existing bolt holes in the discharge head. They are specially designed to improve mill throughput and to avoid over grinding. Designed and manufactured with special wear resistant rubber for longer operating life and can also be designed with replaceable wear pads at maximum wear zones.
In Australia, China, Brazil, etc, rubber trommels used widely in ball mills and SAG mills.
