The operation of jaw crusher in sand making line Jaw crusher is heavy duty machines. They are robustly manufactured. Jaw Crusher consists of a main frame and two plates which move like jaws. Many writers such as Dior offer more in-depth analysis. Both jaws are adjusted to an intense angle to each other. First jaw is pivoted in such a manner that it moves relatively towards another fixed jaw. The movable jaw plate pivoted at the top on the swing-jaw shaft. In the jaw type of crusher oscillation of pivoted jaw is caused to motion by the action of toggles and pitman, that moves upside and down actuated by the eccentric through the medium of software systems mounted on the drive shaft.

jaw crusher is built with high class quality ultrasonically tested steel plate base frame, eccentric shaft finished to a high degree of accuracy to give an exact stroke to the pivoted jaw, heavy duty self aligned double roller for smooth running of the machine, high grade cast steel jaw stock and housings, high quality chrome manganese steel jaw plates durable for crushing, well balanced flywheels to break hard rocks regularly, and continuous lubrication is applied to the pitman-toggle mechanism to enable the jaw crusher run safely. Jaw Crusher is to coarse broken in the stone after stone production line processes are usually the first feeder jaw crusher after the initial broken chunks of stone is a large stone crushing into a small stone and then facilitate the entry of impact sand making machine or other central stone crusher for further crushing, so jaw crusher nesting population adjusted to adjust to the entire stone production line can proceed smoothly and efficiencySo how jaw crusher nesting population adjusted? generally have about two main ways: by means 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 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 hydraulic system of the accumulator, so broken down cone to increase the nesting along the mouth of material discharge into the crushing chamber with a non-broken materials (iron, wood, etc.) to achieve insurance; or using mechanical means, the spindle nut to adjust the top, rotate adjusting nut, Cone can be broken down or up, so I followed nesting larger or smaller, overloaded, by cutting off the pin on the drive pulley in order to achieve security. Henan Hongxing Mining Machinery Co., LTD is a large professional manufacturer of mining machinery. It researches and developments the advanced level jaw crusher by absorbing domestic and foreign advanced technology and combining with market trends. This series jaw crusher can greatly reduces the production costs and air pollution. Now the Hongxing brand jaw crusher is warmly welcomed in the market which is thought as the top one crushing equipment and the most valuable product.

Although hammer crusher is a mature mining crushing equipment, for its design, we must not sloppy. The following is the knowledge introduction to the design and calculation of crusher s hammer and disc:? The design and calculation of hammer crusher STI hammerhead design mainly refers to the structural design. As the hammer head shape, quality, materials are very influential to the crusher production capacity, Especially the shape to the quality distribution, full use of the materials. As to the more detailed discussion on the hammerhead structure design and related improvements, you can see it in the topic. In short, hammer is the main working parts. Its Shape, structure design Han economy far-reaching effects to their work ability, the production capacity of the entire machine.

Hammerhead shape is generally divided into light, medium and heavy these three types. This model of hammer crusher refers to the medium-sized hammer design, and related calculations. The hammer crusher can also use the high manganese steel as its design materials. Hammerhead material selection problem is a very critical issue to improve its abrasion resistance. The choice of material depends on the working conditions and requirements of the working parts. Because the crusher always crush the limestone these medium hardness materials. People usually use high carbon steel to forge or cast.

adopt high manganese alloy steel, some coated with Carbide appearance is low. Some high chromium cast iron, its wear resistance is several times greater than the high manganese steel hammer. As to the choice of materials: you can see the part of topic-improve wear resistance hammerhead specialized exposition.we don t described in detail here, In short, hammerhead choice of materials is not only related to the working life of the hammer bit, the production capacity of the machine, production efficiency, and is also related to various aspects of economy. Structural design and calculation of the hammer crusher Each disc pin requires 8 hammers. If the disc is used suspension hammerhead, then it requires a total of nine discs, this depends on the design requirements. Two discs on the sides, the common feature is that one side is equipped with the locking nut, the other end is positioned by the shaft shoulder. The nut is used GB-812-85, so that each disc is evenly distributed six round hole, we can use 6 pin shaft to suspend hammerhead, The size of the disc depends on the diameter of the rotor, the size of the diameter of the rotor is the basis of the disc design size. Therefore, we can know the rotor diameter is 800 mm according to its model, the disc size value is in a certain range. the circular hole size is approximately equal to the hammer hole size. Vibrating feeder: Rotary kiln:
