3. Package
Packaged by flexible container bags weighing about 1000kg or in iron drums weighing about 850kg.
In addition to all kinds of castings and forgings,we have annual production of grinding media of 30,000 metric tons,
mainly with high Cr, middle Cr and low Cr alloy materials widely used in cement mills, mine mills and coal mills.
We focus on the research and development of the advanced wear-resistant materials and highly efficient production
techniques. We have 10 famous wear-resistant materials experts and technicians.
We have been participating in drafting the National Standard of China Grinding Media GB17445.
