The barrel is divided into intermediate baffles of two or three grinding bins. Theseparating wearhouse plate has holes that are smaller than the diameter of the steel balls in the two abrasive cavities to allow the material to pass through and be further milled. Due to long-time friction between steel balls and materials in the two sides of the abrasive silo, the silo panel needs to be very wear-resistant to shorten the replacement cycle. Some ball mills use double-layered diaphragms to better distinguish the two abrasive cavities and prevent them from collapsing and damaging the body.

Customized Solutions

Customized according to your operating conditions

High-wear working conditions

For highly abrasive materials such as limestone and sandstone, we adopt high-chromium cast iron or ceramic composite materials, which extend the service life by 3 to 5 times.

High-impact working conditions

For high-impact materials like construction waste and metal ores, we adopt a reinforced structure with high manganese steel and alloy bars, delivering excellent impact resistance.

High-temperature working conditions

For high-temperature materials including cement clinker and slag, special heat treatment is adopted to retain hardness and wear resistance at elevated temperatures.
