1.the structure and basic principles of cone crusher
Cone crusher put the material exist between two cones.a fixed outer cone and inner cone which do garden-week campaign make the material crushed or broken. Cone crusher has crushing ratio, high efficiency, low power consumption and other advantages.
Cone crusher is suitable for hard rock mineral compound, fine and ultra-fine crushing.
Cone crusher is widely used in metal and nonmetal mines, cement, sand and metallurgical industries. General application in the crushing hardness ≤ 5 ~ 16 various minerals and rocks, such as iron ore, nonferrous metal ores, granite, limestone, quartzite, sandstone, pebbles, etc.
2.Cone crusher notes
First, the crushing operation of the marker size uniformity of the general operational requirements than crushing high, therefore, the lower part of the crushing chamber shall be a parallel region, while the cycle must speed up the rate of crushing cone, so that the material in the parallel squeezed by more than one region.
Second, the crushing material will be loose,and there is a large increase in volume. To prevent the crushing chamber may cause obstruction, without increasing the nesting population to ensure the required marker size, under the premise must be broken by increasing the diameter of the bottom cone to increase the total discharge section.
Third, cone crusher discharge opening smaller, mixed compound of the non-broken material has resulted in accidents, and because the crushing operation of the marker size demanding, must be worn liner to adjust the discharge opening, Thus cone crusher of insurance and adjustment device is more necessary than the crushing operation. Simon spring cone crusher overload the insurance, the conical compression spring to force the shell to its rise, in order to increase the discharge opening, and expel non-broken material. Nesting population adjusted by adjusting the set to proceed, turn adjustment sets the shell can be driven up or down to change the nesting population size.
Mechanical way, rotating the adjustment of the upper spindle nuts, so broken down or rising cone, so that the nesting population larger or smaller. Cutting off the pin on the drive pulley when overloading.
Hydraulicway, hydraulic spindle gyratory crusher located in the hydraulic cylinder of the plunger, the plunger under the hydraulic oil change can change the volume up and down the crushing cone position, thus changing the nesting population size.The spindle downward pressure, forcing the plunger into the hydraulic oil accumulator in the hydraulic system so broken cone fall to increase the discharge opening when overloading.
