Mill Liners Manufacturer From China

When it comes to mill liners, MGS Casting is a Chinese-leading manufacturer of mill liners and trommels that improve grinding efficiency, reduce downtime, and lead to increased profitability, which specializes in the design, manufacture and after-sales service and support and is a proven provider of total mill lining solutions across the globe.

Mill liners developed by MGS Casting include Ball Mill Liners, SAG Mill Liners, AG Mill Liners, as well as Scrubber Liners. Focusing on the good fitment of liners, in which MGS Casting are experts, results in reduced installation downtime which, in turn, facilitates increased production.

Material Selection For Mill Liners

MGS Casting supplies various kinds of material mill liners to suit different working conditions. Choose the right material that is the key to get a longer span life.

To select the correct materials of construction, a combination of the applications’ function, ore abrasivity, mill size, mill speed size of the balls, and the type of corrosive environment need to be considered. Symptoms of poor liner design, which means your mill liner may require re-evaluation, include a noisy mill and broken mill liners. A noisy mill produces a distinct impact rattling, which indicates that the grinding media is impacting directly on the liner instead of on the toe of the grinding charge. A broken liner, which is particularly severe for large AG/SAG mills, can arise from media impacting directly on the mill liner.

  1. Manganese Steel: This is used for grid liners and generally smaller mills. Its great advantage is that it works hardens under stress, yet the substrate remains tough and can withstand extreme impact without fracture. Its primary disadvantage is that it spreads with impact, so solid liners begin to squeeze together and become extremely difficult to remove, and can damage a mill shell if the stress is allowed to build up to an extreme level.
  2. Low Carbon Chrome Moly Steel (300 to 370BHN): 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.
  3. High Carbon Chrome Moly Steel (325 to 380BHN): 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 are outstripping the properties provided by the standard high chrome-moly steels.
  4. Ni-hard Iron (550BHN): The use of this type of material generally began with Rod Mills and Ball Mills, where impacts were considered low enough for this brittle yet highly abrasive resistant wear material to perform well. However, it is now considered obsolete in light of the use of high chrome irons and chrome-moly white iron.
  5. High Chrome Irons (+600BHN) Cr Iron: It is considered to have superior wear abrasion characteristics, and is generally used in rod and ball mills. It is more cost-competitive but more brittle than chrome-moly white irons.
  6. Chrome Moly White Irons (600 to 700BHN) WI: This casting material is considered to be the ultimate developed and used to date for abrasion resistance in Milling. It is commonly used in cement mills and some of the largest Ball Mills in the world and where performance has not been bettered to date.
