European version jaw crusher professional broken cobblestone

European version Jaw Crusher Which crushing equipment suppliers to produce the best? Hammer crusher main parts and optional.The main parts of the cone crusher manufacturer jaw crusher machine factory in Wuhan hammer crusher hammer, rotor, grizzly, inner wall linings, rack. Hammer and grate bars often replace parts, and play a major role in the crushing process. (1) hammer hammer hammer crusher main working parts. Have a great impact on the quality, shape and material of the hammer crusher production capacity. Hammer bit is proportional to the mass of the size of the kinetic energy of the hammer bit larger, kinetic energy, i.e. the greater the hammerhead quality, the higher the crushing efficiency, and also greater energy consumption.

Therefore, to select the appropriate hammerhead quality, depending on the size of the feed block, from a few kilograms to more than one hundred kilograms. The wear resistance of the hammer is its main quality indicators to improve the wear resistance of the hammer, can shorten the overhaul of parking time of hammer crusher, hammer crusher to improve utilization and reduce maintenance costs. Commonly used forms of the hammer shown in Fig. The common hammerhead shape of the light hammer; a medium hammer head; heavy-duty hammer light hammer, the quality is usually 3.5 ~ 15kg, and more for broken particle size of 100 ~ 200mm soft and medium hardness materials, some of which both ends of the hole, wear can be swapped using 4 times, while the other can only swap 2. Medium-sized hammer, the quality of 30 ~ 60kg, 800 ~ 1000mm medium hardness materials used in crushing. Heavy hammer, the quality of 50 ~ 120kg, mainly for broken chunks of hard materials. Hammer with high-carbon steel forging or casting, high manganese steel casting can also be used. To improve the wear resistance to high manganese low alloy steel ZG30MnSiTi, some hammerhead work surfacing layer Carbide. Recent years, some high chromium cast iron hammerhead composite casting, that hammer handle ZG310 ~ 570 steel hammer with high chrome cast iron several times greater wear resistance of high manganese steel hammer. (2) the rotor of the rotor hammer crusher by a spindle, a rotor disc (or triangular, polygonal linked to the hammer) and hammer. Spindle parts, impact crusher machine rotor supported to withstand. Therefore, the requirements of the material of the spindle having a higher strength and toughness, such as 37SiMn2MoV alloy steel forged. Spindle circular cross section, the maximum diameter is 280mm, bearing Department 200mm. The hammer frame with the 60mm wide flat key is connected to the shaft. Some spindle square section, the hammer frame looper spindle without flat key connection. The disc (hammer frame) used to hang hammerhead. Crusher in operation, the hammer frame in contact with the material, which cause wear, Therefore, a material selected to have a certain resistance to abrasion, and having good welding performance, local wear, the entire rotor repair welding. high speed rotation for static balance and dynamic balance test in order for it to work properly, replace the hammer or the new design of the rotor on the rotor.
