Product Introduction
>Product Introduction
Mill lining board are installed to grinding Ball mill & SAG mill to protec the mill cylinder was abrased & breaked by the grinding process. Mill liners was a very important wear parts for mill machinery in Mining / Cement and other indurtries. These protective linings are made of Alloy steel /Ceramics / Rubbers and composite material.

>Product Advantage
The quality is relatively stable
High Mn-Cr alloy steel (M13Cr2 - M18Cr2) cast ball mill lining baord have been used with a lowest cost and longer usage time than other alloy steel / Ceramics & Rubbers materials.
NGZR have more than 10 years experience of R&D / Manufacutring / After-sales srevice the High Mn casting mill liner for Mining and Cement Indusries. For all mill machinery diameter size less than 6 meters, we guarantee the product quality and operation life for all customer.
Lower usage cost
High Manganese casting ball mill liner plates have long usage life with stable quality, Because NGZR have large production capacity and Advanced Lost foam process full Automatic precision casting line, we can provide more competive price products to all customers. So customer will get lower production unit cost than before.
Customized alloy Steel composition
NGZR foundry was able to match client’s requirement to readjust the Chemical Composition of alloy steel content (Mn: 11-18%) , or increased other special metallic element (Mo /Cu /Ni etc), through special heat-treatment processing, can help this casting liner achieve to special Mechanical performance, to follow different customer’s different working conditions.
Customized drawing size and shape
NGZR foundry can follow customer’s drawing of exist mill liner to customized . Also we can revised the exist mill liner plate shape / thickness and wearing quality to help customer get lower liner cost and higher production efficiency.
Door to door measure & Installation Guide
If customer can’t provide drawing of existing mill lining, NGZR will arrange our service engineer come with free of charge to measuring the size and design of the one-stop service.
If customer required, NGZR provide door to door installation serivce with pay charge.

How to choose correct alloy material and shape to reduce production cost?
1.Fit the existing mill size to choose alloy material
The existing mill diameter size become large (more than 6 meter), the mill liner will be come under more impact power from grinding media and mineral, so the liner should be more toughness to avoid to broken.
When the mill diameter less than 6 meters, can choose the lower unit cost of liner alloy material such as M13Cr2.
2.Fit the RCM to choose the liner thickness size
The RCM ( reliability-centered maintenance) time of mill become loner, the mill liner thickness size should be increased. However, the liner thickness size increased, the liner total weight will enlarge, so the liner purchased cost will rised, and the Production efficiency will reduce.
So choose the less thickness size to fit the Mill rational RCM time will Improve production efficiency and reduce production costs.
3.Develop and design the better shape of liner
The better shape ( The step at cylinder liner inside) will help Mill have more effective grinding, increased the production capaciy and quality!
NGZR can help customer to Research & Develop the liner shape for existing mill machiery.
