Therefore, modern crushers have kept this name more in force tradition than sense. The operating principle of the modern mills dcc and cmd is based on a complex movement of the cone. That is what creates the necessary conditions for the destruction of the material in the crushing chamber, which is served under gravitational forces from above. Once in the workspace, the material is subjected to repeated compression crushing cones, broken down and under the influence of gravitational forces, falls deep into the crushing chamber for as long as the size of his pieces will not appear smaller than the width of the discharge slot, and will not create conditions for removing it from the crusher. A typical representative of cone crushers is the crusher ksd KSD-2200Gr (Gy – means the gross fragmentation designation in the name of Crusher T – involves a subtle crush) production Uralmashzavod.
Its design – typical for this class of grinders. Main details crushers are: body rolling cone, coated plates of high-manganese steel; Distribution plate; spherical thrust bearing, which rests on the rolling cone shell; the central axis of the bore and the eccentric axis of the crusher, which intersect at one point; Eccentric assembly; bed; blocks springs on the perimeter frame (their number is chosen depending on the conditions necessary efforts crushing), also act as a safety device; adjusting ring (Adjusts the width of the discharge slot); cooker – stationary crushing cone; housing shaft grinders; water bath; loading hopper; boot platform. According to the principle of crushing mills cmd and csd are identical. They differ primarily in the form of the crushing chamber, ie, profiles crushing cone (movable and fixed). Cameras for fine crushing take smaller chunks and at the same width of the discharge gap give a finer product than the chamber for secondary crushing. This is achieved by a longer parallel to the zone, which is guaranteed by the capture of pieces of divisibility of the material. Cone crushers were invented in the second half of the xix century and preserved some original designs. In recent years, noticeable heightened interest in the theory of these machines. The domestic industry is developing new technologies and keeps pace with the time and European standards, offering the consumer a decent and reliable product.
