Chrome Moly Mill Liners By Hunan JY Casting

Mill liners operate in high-impact areas and with a broad range of variables to consider. Finding a suitable mill liner can be hard work.

Chrome-moly mill liners always are made in Low Carbon Chrome Moly Steel and High Carbon Chrome Moly Steel, which are widely used in SAG mills for mine and Ball mills for the cement industry. The choice of alloy used for the liners also depends on the operating conditions of each mill or plant. Huihe’s product solutions can be tailored to enhance grinding efficiency and optimum liners lifetime.

  • High Carbon Chrome Moly Steel(AS2074 L2C). This steel is now considered the main material used for SAG mill liners. There are a number of variations with either different carbon or chrome contents. The variations tend to have a bearing on the size of the liner and its section thickness. There is ongoing development within this area as the size of the liners is outstripping the properties provided by the standard high chrome-moly steels.
  • Low Carbon Chrome Moly Steel(AS2074 L2B). It Was generally used for mill liners (AG, SAG, and Ball) prior to the movement to higher carbon content steels. It has excellent wear characteristics with some impact resistance, generally now used for discharge grates where slightly better impact resistance is required compared to the higher carbon chrome-moly steels or for thinner section liners.

We work to remove the complexities involved with the selection process. Our team understands the materials in the mills and what effect they can have on the wrong Mill liner. Whether it’s material, profile, fit, or function that needs addressing, we can help.

Products Description

When it comes to Cr-Mo Alloy Mill Liners, Hunan JY Casting had focused on casting this material for over 20 years. Mill liners from Hunan JY Casting use Cr-Mo materials (AS2074 Standard), provide superior impact and wear resistance in all semi-autogenous milling applications.

The material of mill liners uses low or high Carbon Cr-Mo Alloyed steel, the carbon content depends on the working condition of the mill. Choosing the right material for the right application is our mission, we are always working together with our customers to achieve this.
The right material is upon to :
  • The mineral ground
  • Maximum grinding media diameter (mm)
  • Grinding media filling degree (%)
  • Milling data information
In general, L2B alloy steel is used for high impact conditions, L2C alloy steel is used for low impact conditions. It shall change according to your mineral processing. This ensures that the liner is appropriate to the mineral being processed as well as its wear rates.
