Definitions

  • the invention relates to vibratory impulse crushers of fine crushing, which can replace ball mills.
  • vibratory cone crushers are used in Russia and Japan to produce cube-shaped crushed stone for roads.
  • they can be used as a mill only at low capacities (up to 5 t / h), since the grinding regime requires an increased crushing force and the corresponding strength of units and parts.
  • a disadvantage of the known installation is the loss of crushing force by the crusher due to the flexibility of the body mounted on elastic shock absorbers. Under the influence of the crushing force of the inner cone, the body behaves like a malleable anvil, so the destruction of the material between the cones becomes ineffective. Loss of crushing force reaches 20%. To increase the moment of inertia of the casing, it is necessary to increase its mass by almost 2 times, which sharply increases the cost of the crusher. Thus, the drawback of A very good analogue is low technological indices as a grinding unit.
  • a known installation of a cone vibratory crusher adopted for the prototype (patent for utility model RU N ° 115241, ⁇ 02 ⁇ , dated April 27, 2012) containing a vibratory crusher equipped with a maslostation with discharge chute, installed with the help of elastic elements on a solid surface support frame with electric motor and crusher counter-drive fixed to it.
  • the objective of this utility model is to increase the degree of grinding and productivity of the crusher without its structural alterations, but due to changes in the design of its installation.
  • Another objective is to reduce the size of the installation and ensure the convenience of its placement in the technological chain.
  • a vibratory-pulser mill comprising a vibro-pulsed mill equipped with an oil station with a discharge chute, installed by means of elastic elements on a support frame mounted on a solid surface with an electric motor and a mill counter-drive mounted on it, in which, in accordance with this utility model, the oil station is mounted on a support frame, which is installed len on a solid surface through elastic elements, and the mill is turned on the supporting frame with the vertical plane of the discharge flow perpendicular to the longitudinal axis of the frame.
  • the mass of the latter for the mill of average productivity (about 150 t / h) increases by about 1 ton.
  • the total mass of the support frame with the engine, counter-drive and oil station, being installed on a solid surface through elastic elements, turns the system into an internal cone with a vibrator, an external cone with a mill body and a support frame into a three-mass system in which all participants become dynamic elements moving in space with an amplitude inversely proportional to its moment of inertia.
  • connection of a spring-loaded support frame to the casing gives the casing an additional significant moment of inertia, due to which the casing becomes less flexible when exposed to the crushing force of the inner cone, which proportionally increases the deformation effect of the material layer and its destruction with an increased degree of grinding and productivity .
  • such a three-mass system is characterized by increased compactness and convenience for unloading the product onto the conveyor, which can be installed parallel to the support frame, and not underneath.
  • FIG. 1 shows a general view of the proposed installation of a vibratory pulse mill, and in fig. 2 - its cross section along aa.
  • the installation comprises a vibratory impulse mill 1 with a discharge chute 2, a housing 3, an outer cone 4 and an inner cone 5 with a vibrator 6.
  • the mill 1 is installed through elastic elements 7 on a support frame 8 on which the electric motor 9 is rigidly mounted , maslostantion 10 and counter-drive 1 1.
  • the support frame 8, in turn, is mounted on the solid surface 13 through the elastic elements 12.
  • the starting material is loaded with pieces with a particle size of about 100 mm (for an average mill size).
  • the material fills the grinding chamber formed by the working surfaces of the cones 4 and 5.
  • the latter receives circular swings due to the centrifugal force developed by the vibrator 6, the rotation of which is transmitted from the electric motor 9 through the counter drive 1 1.
  • the material is in the form of particles with an average size of about 1 mm it enters the unloading estrus 2 and further onto the conveyor or screen in the process chain.
  • the housing 3 moves away from its stationary position in the direction of movement of the inner cone 5.
  • the supporting frame 8 is carried away by the housing 3 in its movement .
  • the moment of inertia of the case + frame system becomes almost twice as much as that of the case 3, which accordingly reduces its susceptibility, that is, loss of crushing force.
  • the loss of force was 15–20%, in the claimed case the losses are reduced to 7–10%. Correspondingly increase the degree of grinding and productivity.
  • the present invention can be most widely used in the production of building materials, in particular cement.
