The Jaw crusher is used for Primary crushers and Secondary crushers for crushing all kinds of minerals and rocks with compressive strength less than 320 mpa. There are two types of Jaw crusher:coarse jaw crusher and fine jaw crusher.
Learn MoreImpact crusher is suitable for materials whose compressive strength is under 350Mpa, and particle size is less than 500mm. With end products in cubic shape, the impact crusher is widely used for sand and rock producing in the industry of roads, railways, reservoir, electricity power and building materials and so on.
Learn MoreVertical combination crusher is a kind of new fine and coarse crushing machine, which is developed according to purified parameter based on the crushing technology at home and aboard.
Learn MoreAdvantages of hammer crusher are as follows: big reduction ration: maximum feeding size is 1.3-1.5m; 3-150mm of discharging size; high fineness of discharging size: favorable shape with aggregate; the powdery material is no more than 20%.
Learn MoreBall mill is the key equipment for grinding after the crushing process, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other grind-able materials.
Learn MoreRubber tyred mobile crusher is mainly used in metallurgy, chemical industry, building materials, water and electricity industries for processing materials need to be moved, especially used for stone crushing in highways, railways, hydroelectric projects and other liquidity operations.
Learn MoreIron Ore Processing Plant is mainly composed of jaw crusher, ball mill, spiral classifier, mixer, flotation machine, ore concentrator and dryer machine.
Learn MoreThis process includes vibrating feeder, jaw crusher, impact crusher, vibrating screen, belt conveyor and centrally electric controlling system, etc.

Get DetailsBall mill that works on the principle of impact is an efficient technique of size reduction through grinding. The size reduction is an important factor for many industrial applications as this process is carried out to increase the surface area, to intimate mixing and to improve dissolution rate, solubility, binding strength and dispersion properties.
Get DetailsBall mill. The opening is closed and the mill is rotated for several hours. Grinding can be carried out in either wet or dry but the former is carried out at low speeds. The advantages of wet grinding are less power consumption,increased capacity,no dust formation etc • Weight of the balls: With a heavy discharge of balls,we get

Get DetailsThis paper involves an experimental and numerical study on the grinding media dynamics inside a baffled ball mill under different solid flow regimes: cascading, cataracting and centrifuging.
Get DetailsThe work input to a mill increases in proportion to the speed, and ball mills are run at as high a speed as is possible without centrifuging. Normally this is 70-80% of the critical speed, the higher speeds often being used to increase the amount of cataracting taking place in order to break hard or coarse feeds.
