Ball Mill Liners

SHELL PLATES, LIFTER BARS, HEAD PLATES, GRATE PLATES, PULP LIFTERS, CENTRAL CONES, TRUNNION AND BELL MOUTH LINERS

Ball mill liners from MGS Casting maximize the lifespan and performance of your ball mill, with a selection of rubber and rubber composite liners available. Refined through ongoing design improvements, our ball mill liners maximize uptime and service intervals while providing an improved crushing of the ore.

Our ball mill liners solutions can be fitted with MultoMet composite lifter bars, shell plates, and head plates. The manganese steel and alloy steel, attached to the leading edges of the lifter bar array and embedded within shell plates and head plates, ensuring maximum abrasion and impact resistance.

Vertical Roller Mill Wear Parts

SHELL LINERS, HEAD LINERS, WEDGE SHELL LINERS

Vertical Roller Mill Wear Parts such as tires, grinding ring segments, armor rings and spindle shields are cast from our high chromium alloy irons and fully heat treated for optimum mechanical properties. Tires and grinding ring segments are also accurately machined to tight tolerances for precise fit.

Rollers and Table Segments: Both are cast in High Chrome Alloys in the range of 16% to 27 % with a 55-62 HRC hardness. The use of High Chrome increases the wear life versus low and medium chrome alloys.

We are able to send to your plant site engineers and sales staff to re-engineer and/or draft your vertical mill wear parts in the case that we have not had developed your mill parts in the past.

Manganese Steel Mill Liners

20% MORE WORKING LIFE THAN OTHER SUPPLIERS MANGANESE LINERS

Manganese steel is widely used in casting kinds of mill liners. 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.

MGS Casting is one of the largest manganese steel mill liners manufacturer in China. In most cases, we have manufactured many types of mill liners and also stock some common manganese mill liners. In some cases, MGS Casting has even improved the conventional design of those manganese mill liners to enhance durability and performance.

Ni Hard Mill Liners

15% MORE SPAN LIFE THAN OTHER SUPPLIER’S NI HARD MILL LINERS

MGS Casting manufactures ni hard mill liners for customer, which are produced with a wear-resistant minimum of 550 Brinell hardness.

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.

Chrome steel mill liners

10% MORE WORKING LIFE THAN OTHER SUPPLIERS MILL LINERS

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.

Chrome-moly steel mill liners

L2B, L2C CHROMIUM MOLY MILL LINERS FOR AG, SAG, AND BALL MILL LINERS

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.

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.

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.
