Our company regulate and produce strictly according to the ISO9001: 2008 Quality standard. The main products are follows: 
1. Wear-resistant grinding ball: Our company main produce Φ25mm-Φ200mm forged steel ball and Φ15mm-Φ150mm low, middle, high chrome casting iron ball. Grinding ball is good in accurate dimension, roundness geometry shape, high hardness and good mechanical properties with good characteristic of anti resistant, no deformation, no break. ZDBA grinding ball is uniform surface hardness, hardness distribution uniform for the advance quenching device in the producing process. 
ZDBA is equipped with advanced casting and forging producing facilities, a full inspection system, well educated professional persons and a management team. We import automatic forging rolling lines for the fast changing market. We also make our advanced heat processing lines. Our products are all produced of good-quality steel. They are cut by plasma cutting machines and heated by electric furnaces which increase the full hardness, impact the toughness and lower the break rate of steel balls. 
2. Steel cylpeb: We absorb the advance technology, add the Cr, Mn, Si, Mg, Al, Cu and others to make the alloy cements. The products produce in the intermediate frequency furnace and fall to the high, medium, low chrome category. Its characteristic is steady quality, high hardness, anti resistant, low break rate, various kinds.
3. Grinding rod: Our company produces a new type of alloy wear resistant steel rod is produced by the method, dimensions completely can be adjusted according to customer requirements, increase flexibility, To eliminate the unnecessary waste. At the same time, it extended the service life, improve the efficiency of the mill production, saves the production cost, reduce the labor of the workers.
