Product Introduction
>Product Introduction
Mill liners are installed to grinding mill ( Ball mill / SAG mill / AG mill/ Tower mill etc) 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.
Mill machinry was used to grind / crush the mineral from square shape to powder, the grinding process is a very important manufacturing technical for mineral processing plant, but this mineral grinding process will abrade & destory grinder machinery, that should be shutdown the grinding process to repair with long time & Substantial loss.
Mn-Cr alloy steel cast liner is the wildly uses and the longest usage history for all kind material liner. As the same useful life time, the Mn-Cr alloy steel liner cost is the lowest.

>Product Advantage
The quality is relatively stable
High Manganese alloy (M13Cr2 - M18Cr2) casting mill liners have been used with a longer usage time history than other alloy steel and 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 mill lining plates have long usage life with stable quality. Because NGZR have large production capacity with Advanced Lost foam process full Automatic precision casting line and Resin-sand Wooden mould manual casting production 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: 11-23%) , or increased other special metallic element (Cr /Mo /Cu /Ni etc), through special heat-treatment processing, can help this casting mill 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 liner, NGZR will arrange our service engineer come to measuring and design of the one-stop service with free of charge.
If customer required, NGZR provide door to door installation guide serivce with pay charge.

Product Uses
>Product Application
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, the liner abrasive wear loss become large , and the liner useful life will shorter, So you should be choose the matrial which have high wear resitance such as high Chromium alloy steel or Alloy -Ceramics composite material etc.
When the ball mill diameter less than 6 meters, can choose the lower unit cost material such as Mn-Cr alloy steel material (M13Cr2- Mn18Cr2).
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 mill liner with best quality 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 of 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.
