Mn-Cr Alloy Steel Cast Ball Mill Liner for Φ3.2×4.5m Ball Mill

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 has more than 10 years of experience in R&D / Manufacturing / After-sales service for the High Mn casting mill liner for Mining and Cement Industries. For all mill machinery diameter sizes less than 6 meters, we guarantee the product quality and operating life for all customers.

Lower usage cost
High Manganese casting mill lining plates have long usage life with stable quality. Because   NGZR has large production capacity with an advanced lost foam process, full Automatic precision casting line, and a resin-sand wooden mould manual casting production line, we can provide more competitive price products to all customers. So customers will get lower production unit cost than before.

Customized alloy Steel composition
NGZR foundry was able to match the client’s requirements to readjust the Chemical Composition of alloy steel content (Mn: 11-23%), or increase other special metallic elements (Cr /Mo /Cu /Ni etc), through special heat-treatment processing, which can help this casting mill liner achieve special Mechanical performance, to follow different customers’ different working conditions.

Customized drawing size and shape
NGZR foundry can follow the customer’s drawing of exist mill liner to customize. Also, we can revise the existing mill liner plate shape/thickness and wearing quality to help the customer get lower liner cost and higher production efficiency.

Door-to-door measurement & Installation Guide
If the customer can’t provide drawings of the existing mill liner, NGZR will arrange for our service engineer to come to measure and design the one-stop service at no charge.
If the customer requires, NGZR will provide door-to-door installation guide serivce with pay charge.

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 is less than 6 meters, you 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
As the RCM ( reliability-centered maintenance) time of the mill becomes longer, the mill liner thickness size should be increased.  However, as the liner thickness size increases, the liner total weight will increase, so the liner purchase cost will rise, and production efficiency will reduce.
So choose the thinner mill liner with the best quality to fit the mill; rational RCM time will improve production efficiency and reduce production costs.

3. Develop and design a better shape of liner
A better shape ( The step of the cylinder liner inside) will help the mill have more effective grinding, increase the production capacity and quality!
NGZR can help customer to Research & Develop the liner shape for existing mill machinery.
