The Reform Of The Jaw Crusher

With the development of mining industry, mining machinery equipment is upgrading step by step.Jaw crusher is a common crushing equipment of the mining machinery equipment, therefore in order not to be eliminated, jaw crusher has to improve continuously.1) so that the material in the crushing cavity is" laminated crushing" at a certain extent by the use of " fixed volume" type linear -- modified gauss curve advanced crushing cavity of professor dai shaosheng.What's more, the pure pressure of crushing effect is five times of the shear stress, the material in the crushing cavity is repeatedly laminating crushed, which leads to the obvious improving of the crushing effect of jaw crusher, also promote a high crushing efficiency and discharge average particle size up to 5-10mm.2) change the nip angle from zero to negative, the material does not jam, but form a longer" equilibrium"with the linear movable jaw plate, the effective length is as long as 30-60mm, so that the discharge is parallel extrusion pressure for a period of time, which further make the material thinner and also aggrandize the discharge.When the material enter the bottom of the discharging area, the opening of crushing cavity increases and the discharging is accelerated, fundamentally eliminate the discharge plug defects as well as improve yield.3) to ensure the extrusion times of the material in crushing cavity and to improve the crushing ratio, the technique properly increase the height of the crushing cavity to constitute the so-called "advanced type"crushing cavity, and to improve the yield, deduces new eccentric shaft speed formula, that is, the eccentric shaft speed of patent product can reach 330-350rpm, which increases the number of the movable jaw to swing and strengthen the crushing function and also improve the machine output.4) the wearing law of the compound pendulum jaw crusher jaw plate is that it is generally easy to wear in the discharge zone of fixed jaw plate, this technology make the fixed jaw plate into linear correction" -- gauss curve".This innovative design got excellent efficiency.Practice has proved, it indeed improved the wear of the jaw crusher jaw plate.And it adopts a new alloy material, which improves the service life of the 2-3 times.Http://www.Crusherscrusher.Com offers.
