Grinding steel ball for ball mill
OurGrinding steel ball for ball mill have following advantages:
1. Material Quality: We buy steel materials directly from Laigang Group, JIYUAN, which are the biggest steel companies in China who specially produce steel for grinding balls.
2. Product Range: We produce special steel grinding balls according to customer requirement. Both cast & forged type and have complete range.
3. Capacity: Our production capacity is now about 100000 MT. This huge production capacity ensures nonstop continuous delivery of media to you.
4. Production facility: At present we use advanced automatic production line which makes sure the quality is highly consistent.
5. Delivery: We provide fast delivery after order confirmation due to automated production system. It can be as quick as 14 days/ 2 weeks depending on requirement.
6. Quality Control: Our company has an independent laboratory, the advanced and accurate lab equipment, to ensure that each step of the production process is performed in accordance with the quality standards.
Grinding steel ball for ball mill are produced by new method of automatic production line, which ensures that the composition of the material, the uniform hardness of the inside and outside. The wear-resistant industry is improved rapidly.
