Stone crushing equipment is the discharge of more than three millimeters in the size of the total discharge of more than 50% of the broken stone machinery. Crushing homework often according to the size of the feed and discharge size is divided into coarse, broken and crushed. Commonly used gravel equipment jaw crusher (to provide equipment: crusher), grappling crusher, impact crusher, composite crusher, single hammer crusher, ring hammer Stone machine, cone crusher, two-roll crusher and so on several.
Jaw crusher working principle: the use of two jaws on the material extrusion and bending effect, when the two jaws near the material is broken, when the two jaws away from the discharge mouth of the block from the bottom of the rough Broken or broken in a variety of hardness materials, gravel machinery. Jaw crusher Application: This crusher has a simple structure, can break the hard material, reliable work and many other advantages are widely used in mineral processing, building materials, silicate and ceramics and other industrial sectors.
Anti-crusher working principle: the use of plate hammer high-speed impact and counterattack plate rebound effect, so that the material by repeated impact and broken crushed stone machinery. Compared to the hammer crusher (hammer is the suspension state), the background of the rotor to break the greater momentum, smash more difficult to adapt to the material, but also reduce power consumption. Impact crusher advantages: counter-crusher than the hammer crusher parts less, high utilization rate.
The roller crusher for the mineral processing, chemical, cement, refractories, abrasive, building materials and other industrial sectors in the crushing of various high and medium hardness of the ore and rock, especially in the building materials industry in the production of melon and mung bean Sand and other products, there are more general crushing machinery more excellent results.
Composite crusher for crushing all kinds of hard minerals, can be widely used in mining, metallurgy, refractories, cement, coal, glass, ceramics, electricity and other industries. Particularly applicable to hard limestone, dolomite, granite, basalt and other artificial sand or highway pavement stone processing broken. Mechanisms in the construction of gravel, in a variety of metallurgical slag crushing range is widely used, as well as other types of crusher compared to the high yield effect.
Jaw stone crushing equipment is the use of two jaws on the material extrusion and bending effect, coarse or broken in a variety of hardness materials, gravel machinery. The crushed stone mechanism consists of a fixed jaw plate and a movable jaw plate. When the two jaws are close to each other, the material is broken, and when the two jaws are separated, the blocks smaller than the discharge opening are discharged from the bottom. Its broken action is intermittent. This kind of crusher is widely used in mineral processing, building materials, silicate and ceramics and other industries because of its simple structure, reliable work and can break the hard materials and other advantages.
Cone-type stone crushing equipment used in the broken or crushed homework gravel machinery. , The average size of the fineness of the discharge is generally higher than that of the coarse crush course. Therefore, a parallel area should be provided in the lower part of the crushing chamber, and the speed of the crushing cone must be accelerated so that the material is in the parallel area By more than one squeeze.
Roller-type stone crushing equipment is the use of the friction of the roller surface of the material into the broken area, so that it is subject to extrusion or split and broken machinery. When used for coarse crushing or the need to increase the crushing ratio, often in the roller surface to make teeth or grooves to increase the cleavage. Roller crushers are usually divided into single roll, twin roll and multi-roll crusher for the number of rollers, suitable for coarse, medium or broken coal, limestone, cement SBM and feldspar.
Hammer crusher with crushing ratio, the average particle size, broken destruction of less, low energy consumption strengths. But because the hammer wear faster, in the application of hard materials broken by the restrictions; the other because the grate is afraid of clogging, it is not appropriate to use it to break the humidity and clay containing materials. This crusher is usually used to break the brittle material, such as limestone, shale, coal, gypsum, chalk, and so on.
Counterattack stone crushing equipment is the use of plate hammer high-speed impact and counterattack plate rebound effect, so that the material by repeated impact and broken machinery. The plate hammer is mounted on a high-speed rotating rotor and arranges a number of counterattack plates at different angles along the crushing chamber.
Composite stone crushing equipment used in building materials, mining, metallurgy, chemical industry broken limestone, SBM, coal and other minerals, the compressive strength of not more than 140 MPa humidity of not more than 15%.
