Optimal mill head protection
Pranston carefully determines the most appropriate design and alloy for these parts according to:
- Rotation speed
- Maximum ball diameter
- Shell liner type
- Grinding media filling degree
- Material ground
- End drilling
Key benefits:
- Increased lifetime
- Design adapted to mill operating parameters
- Handling device available in case of heavy weight
Principle
- Protection of the flange and design to avoid any projection of balls on the linings
Specifications
- Drilling of the castings must fit with the existing shell drilling and also with the slope of the flange
- From Manganese to High-Chrome alloys including martensitic steel
- The alloy choice is directly linked to the design of the casting, the running conditions of the mill and the expected lifetime
