Advantages
High-Strength Structure
The grinding mill shell is welded from high-strength alloy steel plates ranging in thickness from 30mm to 120mm, capable of withstanding impact loads exceeding 3000kN.
Long Wear Life
The inner shell is lined with high-manganese steel or wear-resistant composite material to effectively reduce wear.
High-Precision Manufacturing
The shell's roundness and coaxiality are controlled to ≤2mm, ensuring uniform force distribution during mill operation.
Quality Control
Independent laboratory testing
Chemical composition, mechanical properties, and microstructure testing are performed to ensure material compliance with standard requirements.
Welding Process Certification
All welding processes and specifications undergo rigorous qualification certification to ensure reliable connections.

FAQ
Q: What is a Grinding Mill Shell?
A: The Grinding Mill Shell is the main cylindrical body of the mill. It houses the feed and discharge heads, liners, and grinding media. Its strength and precision directly determine the mill's efficiency and service life.
Q: What materials are used to manufacture the shell?
A: We use high-strength alloy steel plates with thickness ranging from 30mm to 120mm. These materials provide excellent load-bearing capacity and resistance to deformation during continuous operation.
Q: How do you ensure the durability of the Grinding Mill Shell?
A: Durability is achieved through wear-resistant liners, precision welding, and non-destructive testing (UT, RT, MT, PT). Compared with standard shells, our design extends service life by 1.5–2 times.
Q: What is the manufacturing accuracy of your shells?
A: We control roundness and concentricity within ≤2mm, and all flanges are machined with high precision. This ensures smooth mill rotation and stable performance even under heavy loads.
Q: How is transportation and installation handled?
A: The shell is produced in segmented sections, each under 25 tons for easier handling. Bolted assembly allows for faster on-site installation, reducing construction time and overall project cost.
