What kinds of crushers are there?

Cone crusherThe working principle and gyratory crusher, crushing machine but only apply to pieces or fine crushing. The discharge uniformity in size, fine works of general than crushing operation requirements, therefore, in the lower part of the crushing chamber must set a parallel region, at the same time, it must accelerate the cycle of crushing cone in order to speed the material in the parallel region squeezed more than once.The crushing of a relatively coarse crushing crushing operation is large, so the broken loose volume will be greatly increased. In order to prevent crushing cavity may therefore cause obstruction, without increasing the discharge port to ensure the premise of discharging granularity required under must by increasing the diameter of the lower crushing cone to increase the exhaust the total material section.The cone crusher discharging opening is small, with non broken material in more prone to accidents, and because, in fine crushing to the discharge size requirements strictly, must be in the liner wear in time after adjusting the discharge, so the cone crusher insurance and adjusting device of coarse crushing machine is more necessary.Simon type spring machine overload insurance cone crusher, cone shell forced the compression spring and make their own increased, so as to increase the discharge, discharge the non crushing matter. The discharge opening adjustment by adjusting the set of adjusting sleeve is fixed with the casing can rotate with the outer circle of the screw to drive the shell to rise or fall, to change the size of the discharging port. The hydraulic cone crusher insurance and the adjustment way and hydraulic breaker is the same.

gyratory crusherIs the use of cone crusher in the shell cavity in the cycle of movement, squeezing and splitting and bending effects on materials, crushing hardness of ore or rock crushing machinery. With spindle crushing cone at the upper end of the supporting bushing in the beam in the middle of the eccentric hole, the lower end is arranged in the shaft sleeve sleeve rotates, crushing cone winding machine moves the center line of the eccentric motion cycle it is continuous, so the working efficiency is higher than that of jaw crusher. In early 70s, the large crusher per hour can handle 5000 tons of materials, the maximum feed diameter up to 2000 mm.The nesting population adjustment and overload insurance in two ways: one is the gyratory crusher by mechanical means, adjust the upper end of its spindle nut, rotate adjusting nut, cone crusher can decrease or increase the discharge becomes larger or smaller, overload, cut off the pin on the drive pulley in order to achieve insurance; the second is the use of hydraulic hydraulic gyratory crusher, the piston is located in the spindle in the hydraulic cylinder, hydraulic piston change under oil volume cone crusher can change the position, thus changing the size of the discharging port. When overloaded, the spindle downward pressure, forcing the hydraulic oil the plunger into the hydraulic system accumulator, broken cone ensuing decline in the increase of the discharge, discharge into the crushing chamber with non - crushed material material (iron, wood etc.) in order to achieve insurance.

Jaw crusherIs the use of two jaw plate of material extrusion and bending, crusher crushing or crushing various hardness materials. The crushing mechanism comprises a fixed jaw and a movable jaw plate, when the two jaw plate close to the material that is being broken, when the two jaw left less than the discharge outlet at the bottom of the block exhausted. It's broken movement is intermittent. This crusher for a simple structure, reliable operation and can crush hard material advantages and is widely used in mineral processing, building materials, silicate and ceramic industries.In 1980s twenty, the large jaw crushing 800 tons per hour of material crusher feed size has reached about 1800 mm. The jaw type crushing machine has two kinds of commonly used double elbow plate and single brackets. The movable jaw only for simple swing arc at work, so called simple swing jaw crusher; the latter in the swing arc also moves up and down, so called complex swing jaw crusher.In addition, to wear to meet the different requirements of nesting size and compensation jaw plate, also added a nesting population adjustment device, usually between elbow plate seat and the rear frame add shim or wedge iron. But in order to avoid replacing the broken parts of production, can also be achieved by insurance and adjustment hydraulic device. Some jaw crusher is directly driven by hydraulic drive movable jaw plate to complete the crushing action material. These two types of jaw crusher with hydraulic transmission device, often referred to as hydraulic jaw crusher.

Commonly used crushing machines are jaw crusher, counter crusher, gyratory crusher, cone crusher, roller crusher, hammer crusher and vertical impact crusher and so on

Roller crusherIs the use of roll surface friction material bite broken zone and to withstand extrusion or splitting and crushing machinery. When used for crushing or need to increase the crushing ratio, often on the roller surface make teeth or grooves to increase the splitting effect. The roller crusher usually according to roll into the number one roll, double roll and roll crusher is suitable for crushing, crushing or crushing coal, limestone, cement clinker and feldspar and other hard materials below.Hammer crusherIs the use of high-speed impact hammer, crushing machine of material in crushing and fine crushing operations. The hammer is hinged on the high-speed rotation of the rotor, the lower part of the body is provided with grate to control the discharge granularity. The first is sent to a crusher Material by the impact of high-speed movement of the hammer first broken, and gained momentum, high-speed flying the broken plate on the inner wall of the shell and was again broken. Less than a gap grate material is discharged out of the machine, more than grate gap block by hammer impact again in the grate and grinding, until less than grate gap after discharge.Hammer crusher has high crushing ratio, uniform particle size, discharging pulverized material and energy consumption is low. But because the hammer wear quickly, in the application of hard material crushing the limited; because the grate even blocked, not to use it with high humidity and crushing materials containing clay. The crusher is usually used under hard brittle material crushing limestone, shale, coal, gypsum, etc. in chalk.The hammer crusher hammer crusher for ring steel ring, is a variant of the hammer crusher. The comprehensive effect of it by high speed impact and low rolling crushing material, which can obtain more fine products, mainly used for the crushing of coal power plants, but also can be used for gypsum, salt and chemical raw materials some of the hard material crushing.
