Ball Mill

We can design and manufacture grate type ball mill for mineral primary grinding and overflow type ball mill for mineral secondary grinding. The grinding media balls may be made of cast iron, steel, or ceramic, Correspondingly, the inner surface of the cylindrical shell is lined with an abrasion-resistant material such as manganese steel or ceramic.

Diameter: 900mm to 6000mm Length: 3-9.5m

Project Cases

Ball mill for Gold flotation plant

Before entering the flotation tanks, gold ore need to be grinded into fine partible size by ball mill for better flotation effect.

Grate Type Ball mill for Cobalt grinding

Grate ball mill uses the grated discharge mechanism, as the grinding mill rotates, the material is ground and discharged through the grate at the bottom.

Ball mill for Lead and Zinc flotation plant

Flotation separation of the mixed sulfide-oxide lead-zinc ore was achieved by adopting a low-alkaline and non-desliming process.

Iron ore ball mill and hydrocyclone cluster

Hydrocyclone separator will separate the qualified iron ore from ball mill to next flotation beneficiation or magnetic separation

Nickel Processing Ball mill

The extraction of nickel from ore follows much the same route as copper, sulfide ores are ground in order to liberate nickel minerals for selective flotation.

Primary and secondary ball mill for graphite flotation

Graphite beneficiation by flotation is pivotal for anode material industry and conduct to electric vehicle industry.

Lithium ore grinding ball mill

Positive flotation is the main method for spodumene, other methods such as thermal cracking, magnetic separation and gravity separation play an auxiliary role.

Ball Mill for Gold CIL plant

Gold concentrates are sent directly to the leaching plant and dissolved in an aerated sodium cyanide solution.
