Description

A kind of centrifugal crusher and breaking method thereof
Technical field
The present invention relates to rock, mineral, discarded solidifying clods breaking technical field, be specifically related to a kind of centrifugal crusher and breaking method thereof.
Background technology
Centrifugal crusher is widely used in sandstone production line, metallurgical, colliery, ore dressing, the industries such as building materials, traditional centrifugal crusher has the rotor of a High Rotation Speed centered by vertical axis, the broken raw material put in this rotor is discharged at a high speed from the multiple outlets be opened in rotor surrounding rotate the effect of the centrifugal force produced at rotor under, then the material lining formed in the crushing chamber colliding peritrochanteric is broken into fine grained, in order to improve crushing efficiency, at the projecting fixing material casting hammer body of the surrounding of rotor, its smashing principle is, the broken raw material of discharging from the outlet of rotor strikes after material casting hammer body broken, material casting hammer body is fixed on the external margin of rotor, when rotor around rotating shaft with certain rotary speed High Rotation Speed time, if when dropping into the material that has particle diameter larger in the raw material of this centrifugal crusher or the larger hard objects of other particle diameters, because this material is zero in the component velocity of material casting hammer body direction of rotation, differ larger with the speed of material casting hammer body, therefore this material produces greater impact instantaneously to rotor, cause rotor to wear and tear and aggravate to affect rotor life, even cause coming off of material casting hammer body.In addition due to outside cause cause drop into the inventory of centrifugal crusher change time, also for causing falling material to produce greater impact to material casting hammer body, cause coming off of material casting hammer body.Simultaneously traditional centrifugal crusher when rotated, is formed with the same direction of rotor in crushing chamber inside and the rotary wind that is more or less the same of speed and material casting hammer body speed, causes rotor crushing efficiency step-down,
There is following problem in existing centrifugal crusher:
One is in crushing chamber, and material casting hammer body has played blade function, rotates with rotor high-speed, formed in crushing chamber with the same direction of material casting hammer body on and the rotary wind that is more or less the same of wind speed and material casting hammer body speed.Broken raw material is more or less the same in the speed of carrying lower speed and material casting hammer body of rotary wind, then the effect reduction that is broken of broken raw material;
Two is when the raw material supplying amount dropping into disintegrating machine changes suddenly or have the raw material of greater particle size to drop into disintegrating machine, the material casting hammer body of the High Rotation Speed be fixed together with rotor frame can vibrate by rotor when being subject to unstable impact, material casting hammer body come off or accelerates the wearing and tearing of material casting hammer body, reducing the service life of rotor;
Three is when improving the output of centrifugal crusher, needs to add trochiterian diameter, increases the power of drive source.
Summary of the invention
In order to overcome the deficiency of existing disintegrating machine, the invention provides a kind of crushing efficiency high, long service life and the energy-conservation disintegrating machine of disintegrating machine drive source can be realized, comprise rotor and the disintegrating machine for carrying this rotor, it is characterized in that: described rotor comprises rotor body, rotor top plate, rotor base plate, thrower head and material casting hammer body device, described rotor top plate and rotor base plate are installed on rotor body, rotor top plate is parallel with rotor base plate and keep at a certain distance away, and between rotor top plate and rotor base plate, form the discharging opening of more than three, described thrower head is made up of hard material, be installed on the end of each discharging opening, described material casting hammer body device comprises the hammer body fixed mechanism be installed on rotor base plate, be installed on the material casting hammer body on hammer body fixed mechanism swingably, this hammer body fixed mechanism is arranged at discharge outlet and is arranged in rotor periphery, material casting hammer body revolves round the sun along with rotor and can swing around hammer body fixed mechanism, and the striking face of material casting hammer body protrudes from rotor top plate towards vertical direction.
Further, hammer body fixed mechanism and material casting hammer body removably connect.
Further, hammer body fixed mechanism comprises holder, swing arm and arm shaft, and this holder to be installed vertically on rotor base plate and to connect with rotor top plate, and arm shaft is arranged on holder, swing arm to be connected with holder by arm shaft and can to swing around holder, and material casting hammer body is installed on swing arm end.
Further, material casting hammer body and swing arm are Split type structure, or one-body molded with swing arm.
Further, the outer rim at rotor base plate is given prominence in swing arm, the crusher chamber inwall of material casting hammer body and disintegrating machine leave certain spacing and material casting hammer body bottom to downward-extension.
Further, the shape of the striking face of material casting hammer body is erect the rectangular shape or polygon or toroidal grown.
Further, swing arm is one or more.
Further, the shape of swing arm is bar-shaped or the ventilative tabular in fusiform section configuration or in open-pore construction.
A breaking method for centrifugal crusher, described centrifugal crusher is above-mentioned centrifugal crusher, is characterised in that:
Building stones are dropped in disintegrating machine;
Building stones enter into the central part of rotor under the influence of centrifugal force, after the material lining in rotor body rotates, broken under the effect of discharging opening end thrower head, and broken from the material lining that the building stones that each discharging opening throws away collide around crushing chamber of crusher;
Material casting hammer body rotates integrally with hammer body fixed mechanism and rotor, when the material dropping into disintegrating machine changes, material casting hammer body swings around hammer body fixed mechanism, and buffering material is to the impact of material casting hammer body, and this material casting hammer body can suppress the generation of crushing chamber inward turning return air simultaneously.
Further, the form of material casting hammer body striking face, according to the rotary speed of the kind of broken raw material and rotor, simultaneously in conjunction with on the basis of the abrasiveness of material casting hammer body and the crushing efficiency of material casting hammer body, selects one or more forms.
From the above-mentioned description of this invention, disintegrating machine provided by the invention and breaking method, significantly can improve crushing efficiency, realizes the energy-conservation of disintegrating machine drive source; Improve crusher rotor and resist the ability dropping into raw material and change suddenly when High Rotation Speed, improve the service life of disintegrating machine.
