With several decades of development, CIC has become the Manufacturing Base of Lining of Semi-autogenous Mills
1. Optimizing Manufacturing Process, Guarantee Lining Quality
Our high quality linings manufactured by advanced process have covered a wide marketing of semi-autogenous mills.
2. Optimizing Lining Design, Eliminating Break of Lining
A main working function of the lining is to lift the milling ball to a reasonable height, then fall along right rack and smash against the material enrichment area at the bottom of the mill in order to crush the material effectively. So it is greatly important of reasonable optimizing the lining design and correct guiding the milling ball running track in order that guarantee the optimized operation condition in the mill and effectively protect the shell lining of semi-autogenous mill, meanwhile, can eliminate lining break, prolong the service life and decrease effectively unit wear of linings and milling ball, and improve the hour production per machine.
3. Focusing on Detailed Operating Condition, Improving Users' Benefits
Optimizing the lining design based on the wear forms of linings in different operating conditions maximally decrease the crashing function of the linings, and effectively decrease the weight of scrap linings. Improving the shape of linings can effectively improve the relative motion state between milling balls and linings, then decrease lining wear by material and milling balls and prolong the lining service life while reducing the users' production cost.
