Rubber Mill Lining Systems 8 Common Types To Buy

Mill liners have undergone evolution over time.Liners differ in materials of construction and design, size and shape.A mill liner design is driven by handling issues, casting technology, materials of construction and application.Owners choose a liner based on numerous factors.Hydraulic liner handlers are chosen for larger mills whole manual liners are preferred to smaller mills.Read and know about the 8 different types of mill lining systems that exist today.Nihard liners these were used in ball mills and rod mills where there is low impact and the brittle material can sustain it easily.These have hardness of 550 bn.The liners are highly wear resistant but chrome moly white iron and chrome moly irons supercede them.High chrome iron liners these come with better abrasion resistance and have hardness of 650 bn.These are used in ball and rod mills.These are more cost-effective as compared to chrome moly white irons.Chrome moly white iron liners these are perfect in large ball mills for abrasion resistance.The hardness is 700 bn.These have full martensitic matrix and boasts of high volume of main complex carbides.Rubber liners the choice of rubber is common in ball mills due to the higher wear life, convenient change out and reduced expenses.You can use them as rubber steel composites in primary mills.Rubber steel composites, due to better financial yields, are becoming more and more popular.The fittings and bolts in rubber mill liners are much lighter as compared to steel liners.However, primary mills cannot be suited well with rubber alone.The runner needs to have 500 - 600% elongation factor, 55 - 70 duromter hardness on a scale and a minimum of 20 mpa tensile strength.High low double wave liners these are convenient and are used commonly.However, for a specific mill, a proper angle has to be specified.In the first setup, it is tough to get the profile right.Normally, some changes are needed while a plant moves to operational stage from initial commissioning stage and changing the features of the ore throughout mining operations.Wedged liners these are not used too often these days.Such kinds of liner blocks are wedged in with the help of bolted lifter bars that make simple castings possible from the blocks.Grid liners these are more cost-effective for ores of highly abrasive types, and are perfect for higher critical speed mills as well.Grid liners are ball mill liners and are light in weight.The liners are filled in with the balls, which offer a powerful wear material.These are made of manganese steel that spreads often and makes removal tougher.There can be compromised safety issues due to dropping balls when staffs walk into the mill.Magnetic liners these have permanent magnets integrated in rubber moldings.As compared to rubber liners, these have higher costs.However, these can offer hassle free operations for many years with very less wear.Where wear issues are a main consideration, these can especially be applied.
