subject: These two types of hydraulic transmission equipment jaw crusher [print this page] These two types of hydraulic transmission equipment jaw crusher, often referred to as the hydraulic jaw crusher. Gyrating crusher cone crusher machine is the use of cone cavity within the shell of the cycle exercise, have squeezed the material, splitting and bending, crushing all kinds of hardness of ore or rock crushing machinery. Broken cone with the top of the spindle bearing bush in the central beam, the lower end of the eccentric sleeve is placed in the hole. Shaft rotation, broken cone around the center line for the eccentric cycle exercise machine of its crushing action is carried out continuously, so efficiency than jaw crusher. To the early 70s, large gyratory crusher has been able to handle the material per hour, 5,000 tons, the largest feeding up to 2,000 mm in diameter. Gyratory Crusher two ways to achieve the adjustment of discharge opening and overload insurance: First, use mechanical means to adjust the top of the spindle nut, rotate adjusting nut, cone crusher can fall or rise, along with changes to the nesting population bigger or smaller, overloaded, by cutting off the pin on the drive pulley to achieve insurance; The second way is the use of hydraulic breakers hydraulic cycle, the spindle is located in the hydraulic cylinder of the plunger, the change under the plunger hydraulic oil can change the volume up and down position of crushing cone, thereby changing the size of discharge opening. Overloading, the spindle downward pressure, forcing the plunger into the hydraulic oil under the accumulator in the hydraulic system, so that subsequently broken down in order to increase cone discharge opening, the discharge of materials into the crushing chamber with a non-broken materials (iron, wood, etc.) in order to achieve insurance. Cone crusher gyratory crusher machine working principle and the same, but only for operations in the crushed or finely broken machinery. , The crushing operation of the row of the general uniformity of particle size than crushing the high operational requirements, therefore, the lower part of the crushing chamber shall be a parallel to the area, the same time, the cycle must speed up the rate of broken cone, so the material in the parallel area more than once within the extrusion.
Crushing operation in fairly thick pieces of broken big job, so the volume had broken loose after a larger increase. To prevent the crushing chamber may give rise to obstruction, without increasing the discharge opening to ensure that the required size of the premise of discharge must be broken by increasing the diameter of the bottom cone to increase the total discharge section. Cone crusher machine discharge opening smaller, mixed with a compound of the non-broken things easier cause of the accident, and because of, the crushing operation of the demanding schedule of particle size must be adjusted in the liner wear in time after the discharge opening, which tapered crusher insurance and adjusting device is more necessary than the crushing operation. Simon spring cone crusher overload the insurance, the conical compression spring to force the shell to increase their own in order to increase the discharge opening, the discharge of non-broken material. Nesting population by adjusting the adjustment to be set, turn the adjustment sleeve solid shell can be filled with its cylindrical shell on the thread to bring up or down to change the size of discharge opening. Hydraulic cone crusher of insurance and adjustment method and the same hydraulic gyratory crusher. Roll crusher is the use of friction roller surface area the material broken into bite so bear squeeze or split and broken machinery. When used for coarse crushing or the need to increase the crushing ratio, often made in the roll surface of the teeth or grooves to increase the splitting effect. Roll crusher is usually divided by the number of roller single roll, double roll and multi-roll crusher, for crushing, breaking or crushing of coal, limestone, cement clinker and feldspar in the less hard material. Hammer crusher is the use of high-speed impact hammer effect on the material for crushing operations in the broken and broken machinery.
This is repeated until it is broken into the desired size and from the plane. Compared with the hammer crusher, impact crusher broken than the larger, and can make better use of the rotor speed impact energy. However, due to plate hammer easy to wear, it is broken in the application of hard materials is also limited, often used to rough broken, crushed or broken bits of limestone, coal, calcium carbide, quartz, dolomite, iron pyrites, gypsum and chemical raw materials such as the following in the hard brittle materials. Ring hammer crusher main purposes: The Series Ring jaw crusher is suitable for crushing all kinds of brittle materials, such as coal, coal Chin, coke, slag, shale, loose limestone and so on. The compressive strength of the material not more than 10MPa, the surface water is not more than 8%. Winnowing hammer crusher used in building materials, brick, coal, metallurgy, mining, power, light industry and other industrial sectors, for crushing coal, shale, cinder, carbon, lime, cement guessed, Penghu and the bentonite hard-brittle materials. Described above, several sand and gravel production line equipment in the sand and stone crushing production line equipment is essential. Jaw crusher for cement, coal preparation, power generation and building materials to meet the crushing medium hardness and brittle materials such as limestone and coal. Maximum compressive strength of not more than 1500kg/cm2.
