crusher equipment

Lithotripter(crusher) is the exclusive compound content of particles larger than 3 mm of the total emission rate 50% or more of the crushing machine. Operations often broken by feeding and nesting into coarse grain size of the broken, the broken and petty. Gravel equipment commonly used jaw crusher, jaw crusher, impact crusher, impact crusher, compound crusher, single-stage hammer crusher, vertical crusher, gyratory crusher, cone crusher machine, roll crusher, double roll crusher, combo breaker, a molding machine broken several.

Jaw Crusher jaw plate on the use of two materials extrusion and bending and breaking all kinds of coarse broken or hardness of the material in the crushing machine. The broken body from the fixed jaw plate and movable jaw plates, jaw plates close to the time when the two materials Jibei broken jaw plate away when the two nesting population is less than block from the bottom of the discharged material. It's crushing action is carried out intermittently. This stone crusher due to simple structure, reliable and can be broken advantages of hard materials are widely used in mineral processing, construction materials, silicate and ceramics industries.

80 to 20 of the 20th century, 800 tons of material per hour, breaking a large jaw crusher to a particle size has reached approximately 1,800 mm. Commonly used jaw crusher with elbow board and two single brackets. The former moving jaw at work only a simple swing arc, so called simple swing jaw crusher; the latter for the swing arc to move up and down also, so called complex swing jaw crusher. Jaw Crusher widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry and other sectors, breaking strength no more than 320 MPa of various materials.

Single-plate jaw broken elbow mobile jaw plate up and down movement to promote the role of nesting, and its level of travel is greater than the upper part of the lower part of bulk materials easily broken, so the broken above the elbow plate efficiency. The disadvantage is that jaw plate wear faster, and the materials have been smashing the spontaneous increase in energy consumption. In order to protect the important parts of the machine is not damaged due to overload, and often the shape of the small size of the brackets designed for weak links, overload the machine when it first deformation or fracture.

In addition, to meet the requirements of different marker size and compensation jaw plate wear and tear, but also the addition of nesting population adjustment device, usually in brackets after the frame between the seat and adjust the pads or radiotherapy, wedge. However, in order to avoid damage to replace broken parts to affect production, but also can be used hydraulic equipment to achieve security and adjustment. Some jaw crusher also has a direct hydraulic drive to drive fixed jaw plate, to complete the materials in the crushing action. These two types of hydraulic transmission equipment jaw crusher, often referred to as hydraulic jaw crusher.

Gyrating crusher cone crusher is used in the shell cavity of the cycle within the cone movement of materials generated extrusion, splitting and bending and hardness of coarse broken all kinds of large-scale ore or rock crushing machinery. Broken cone axis with the upper bearing bush in the middle of the beam, the lower end of the eccentric sleeve is placed in the hole. Sleeve rotates around the broken cone axis for eccentric cycle exercise machine of its crushing action is continuous, and therefore the efficiency of higher than jaw crusher machine. To the early 70s, large gyratory crusher has been able to handle material per hour, 5,000 tons, the largest feeding up to 2,000 mm diameter.

Gyratory Crusher two ways to achieve nesting population adjustment and overload insurance: the first is using mechanical means, the spindle nut to adjust the top, rotate adjusting nut, cone can be broken down or up, so I followed changes nesting bigger or smaller, overloaded, by cutting off the pin on the drive pulley to achieve insurance; The second way is to use 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 the cone crusher location, thus changing the nesting population size. Overload, the spindle downward pressure to force the plunger into the hydraulic oil under the accumulator in the hydraulic system so broken down cone to increase the nesting along the mouth of material discharged into the crushing chamber with a non-broken materials (iron, wood, etc.) in order to achieve security.
