Mill Liners Materials Used In Their Construction

The selection of materials while constructing mill liners is highly important.These liners work in tough conditions and therefore it is vital to ensure that they can stand the harsh work environment.Selection of material depends on several factors such as size of the mill, its speed, abrasivity of the ore and the function of the application.The choice of material can't be in isolation.Here are some of the primary components used during construction of mill liners.Austenitic manganese steel (ams) ams is generally used for making grid liners and smaller mills.One of its biggest advantages is that it can work under high stress and can withstand a lot of impact without suffering any facture.However, its primary disadvantage is that it spreads with impact and once it begins to squeeze it is very hard to remove.It can damage the shell of the mill if stress is built at an extreme level.Low carbon chrome moly steel it was earlier for ball, ag and sag liners.One of its primary features is its excellent wear capabilities and it is highly impact resistant.It is now used for discharge grates where a little better resistance is required.High carbon chrome moly steel it is generally the main materials for sag liners.There are multiple variations in carbon or chrome and they have an impact on the section thickness.Experts are continuously developing this area as the liner's size is outstripping its properties.More developments are expected in this in the coming days.Chrome moly white iron it is the ultimate material used for developing abrasion resistant milling systems.Big and reputed cement and ball mills use it since it boasts of top-notch performance.High chrome iron high chrome iron has excellent wear abrasion characteristics and is cost effective.However, it is a little bit more brittle as compared to chrome moly white iron.Still this is in great demand in the market.Nihard iron rod and ball mills used nihard iron because of its high abrasive resistant properties.It is, however, brittle and today has become almost obsolete.The choice of material has to be perfect to ensure safety and optimum performance.Any compromise on the selection of material can have detrimental effects and take production for a toss.It will result in the loss of productivity, money and manpower.The material has to be pure to deliver optimum performance and boost productivity.
