Boltless Mill Liners for Grinding Fine CaCO3 Powder Description:

In 1994, we designed the first super fine powder pulverizing ball mill production line and the boltless ball mill liners applicable to the super fine pulverizing field in China, which can achieve ideal output on the fineness of finished products with 2μm∼90μm.

In Φ2.2 x 6m ball mill, the capacity is 3.2mt per hour on 2μm∼10μm, which has achieved leading level at home and abroad.

In 2000, we designed the first set of the boltless liners applied in a super fine powder vibrating mill in China.

In 2003, we designed and manufactured ball mill liners used in the largest super fine powder ball mills for Anhui Guofeng Nonmetal Hi-tech Material Co.(Jiuhua Calcium Co.) in China.

Ball mill super fine powder pulverizing process mainly relies on liners.
