Grinding Balls For Mining Industry
Chrome Alloyed Grinding Balls-Dia20mm-150mm (High Cr/Medium Cr/Low Cr)
Products Description
Grinding ball is widely used in cement, metal mining, power plant and chemical industry etc. The hardness reaches up to 64HRC(the surface and inner hardness tolerance with in 3HRC unit), which makes the wear-resisting property much better than forged ball. The property- low wear rate, good toughness and less breakage, prolongs its life, improves the productivity of the ball mill, and lowers user's cost.
Processing Technique
Intermediate frequency furnace smelting and mix chromium based on requirement.
Constant temperature casting process ensuring the quality, no solid nonmetallic impurity, no pore, no mal-roundness etc...
Oil-immersed quench harden treatment enhance the hardness, annealing process changing the internal organizational structure, lowering the breakage, and improving the performance.
Products inspection was done by advanced spectrometer and durometer imported from Germany.

Company History
In 1989, Liubang Casting Factory, as a individual, was established. We mainly used coke smelting reduction technics, and the products were casting grinding balls and bars.
In 1996, Peixian County Tongda Casting Co., Ltd. was established. We became a general taxpayer. One medium frequency furnace production line was introduced into our production, together with the annealing process technics.
In 2002, our factory was moved to Liubang Industrial Park, Peixian County, Jiangsu Province. The overall property had a qualitative improvement
In 2008, renamed as Xuzhou H&G Wear Resistant Co., Ltd...12, 000 square meters standard workshop, 3 medium frequency furnace production lines, 2 furnace annealing equipment, and 2 oil-immersed heat treatment equipment were put into production. Also, better technology and equipment was used for IQC and OQC.
In 2012, D-win Metal Material (Shanghai) Co., Ltd. was established in Shanghai, a wholly owned sales subsidiary, intending to develop international business.
In 2013, 800 square meters office building was put into use in our factory, making great progress in both work environment and employees.
