The general advantages in Semi-Autogenous Grinding Mill Liner are as follows:

In the recent 20 years, our liners have been widely used in large,medium and small ball mills in Chinese power generation, mining, cement, chemical engineering and metallurgical industries and super fine pulverizing equipments. It is the only recommended liner productin the latest standard of the electric-power industry in China.

Customer-made Mill Linings:
In addition to our patented Boltless Mill Linings, we can produce liners as per the request of customers.
So far, we have been the regular suppliers of mill liners Now, we have supplied steel caps inserted in rubber lifters for SAG mills and AG mills to some mines in Australia and New Zealand.

Depending on the specific working conditions,all wear parts can be ordered as Manganese Steel,high Cr cast iron or Cr-Mo Alloy Steel.
Our foundry has complete melting, heat treatment and test equipments,such as mid-frequency induction electrical furnaces,quenching and tempering furnaces, blast shot,spectrometer,Rockwell and Brinell Hardness tester,impactor,UT tester and metallographic microscope.
We achieved the certificate of quality management system ISO.
We have been exporting castings to oversea

Specification:
According to drawings, heat resistance, surface treatment requirement, Various types of 2D or 3D drawings are acceptable, etc.
Cost effective:
Integrated production from mold-making to post-processing is completed in our own factory. 
This can effectively reduce the manufacturing cost.
We have first rate production line, the most professional staff, and the advanced equipment and inspection method for casting. 
super quality,competitive price and strict delivery time.
