Our service:

1. Before sales, we will fully understand the customer's working conditions and recommend the most appropriate material selection to the customer.

2. Provide customers with drawings based on their machine models, spare parts dimensions, etc. 

3. After sales, we will continue to pay attention to the usage of the product and provide timely help.

Balls in ball mills have different milling effects on materials depending on size, weight and material. Different sizes of steel balls can perform better milling in a certain proportion in the same abrasive silo.


Our company provides professional matching service for steel ball, and at the same time, we recommend the steel ball material that is most suitable for your working conditions and materials.

1:There are no exact corresponing value between rockwell hardness(HRC) and brine hardness(HB),so ,this two kind of hardness value can be inspend used
2:The hardness in the 40%deepness of casting section should be lower than 92% hardness of surface.
