2-roll crusher is suitable for rough and intermediate crushing brittle materials, such as cement, chemical industry, electric power, mine, building materials and metallurgy. the size of feeding material is large, output size can be controlled, and it is possible to effectively destroy the material whose compressive strength is less than 160 mpathe roller crusher, a mine machinery, is also known as the twin roll crusher. It is mainly used for crushing ores. the machine has the advantages of small size, large crushing ratio low noise, simple structure and convenient maintenance, uniform particle size of crushed materials, low over-crushing rate, convenient maintenance, sensitive overload protection, safety and reliability.roll crushers apply shear or compression to the material that is going to be reduced in size. this action occurs between two hardened surfaces. the speed and diameter of the rolls, the desired capacity, and the feed and product size distribution are all critical in the

ball mill is crucial equipment for grinding after materials are crushed. materials, fertilizer, porcelain and glass industry etc. ball mill has two ways of grinding: dry xbm-mining mchinery:mining equipment,stone crushers,grinding crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials so that pieces of different composition can be differentiated.the small tonnage glaze ball mill is the main machine used to make glaze ceramic grinding balls by the industries of producing household porcelain, electrical porcelain and building porcelain. It is applied to grind different glaze materials with different colors and has features of good grinding quality, compact structure, little noise, and
the maximum particle size of a limestone sample received from a cone crusher was 2.5 cm. It was required to further crush it down to 0.5 cm in a roll crusher with smooth rolls. the friction coefficient between steel and particles was 0.25, if the rolls were set at 6.3 mm and both revolved to crush, estimate the diameter of the rolls. solution oleg neikov, in handbook of non-ferrous metal powders, 2009. tumbling ball mills. tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on a small and large scale.. grinding elements in ball mills travel at different velocities. therefore, collision force, direction and kinetic energy between two or more elements vary crushers and cone crushers whereas rod ills and ball mills, 4.2 size control: neither crushers nor grinding mills are ery precise when it comes to the correct sizing of he end
