A kind of vertical multi-stage super-fine crusher
The utility model relates to a kind of for sandstone, ore etc. being carried out to the standing crusher of super fine crushing, especially by multiple stage crushing, meets discharging requirement.
At present, in mining industry, people adopt disintegrating machine to carry out thinning processing to oversize rock material or ore etc.Take iron ore as example, ore after exploitation need to just can reach discharging requirement through two sections to four sections disintegrating machines and one section of processing to three sections of ball mills, needs through sieving closed circuit after fragmentation, filter out those excessive ores of particle diameter in this fragmentation, and return again broken; The satisfactory ore of particle diameter with conveyer belt, delivers to next section of disintegrating machine or ball mill is processed.Existing crushing process is complicated, equipment has variously caused the cost of whole fragmentation and process of lapping large, operation energy consumption is high, and occupation area of equipment is large, building stones sieve and course of conveying in mostly be open work, surrounding environment is had to certain destructiveness.
Utility model content
For problems of the prior art, the purpose of this utility model is to provide a kind of vertical multi-stage super-fine crusher.
To achieve these goals, a kind of vertical multi-stage super-fine crusher of the utility model, described disintegrating machine comprises tubular shell, the upper end of described housing is provided with charging aperture, the lower end of housing is provided with discharging opening, the inwall of housing is coated with liner plate, on described liner plate, be provided with the multi-layer annular dividing plate extending internally, adjacent two described dividing plates and inner walls surround one and only have the open crusher chamber of inner ring surface, the rotating shaft of downward-extension is installed in housing, described rotating shaft is equipped with the tup fixed cover with this rotating shaft rotation outward, described tup fixed cover outside is fixed with tup, described tup is staggered from top to bottom, the position of the inner ring surface that tup and described crusher chamber are open matches, tup clashes into after material, squeezed into crusher chamber, material relies on self and the shock of liner plate and the mutual shock between material to complete shattering process in crusher chamber.
Further, every layer of described tup that two intervals, 180 degree are set, staggered 90 degree of every two-layer tup arrange.
Further, described dividing plate level extend internally or downward-sloping certain angle extend internally.
Further, described tup, described dividing plate and described liner plate are made by known high-abrasive material.
Further, as the lower end of the described housing of discharging opening, without grate bar, described rotating shaft is by the rood beam support of housing lower end.
A kind of vertical multi-stage super-fine crusher of the utility model, can carry out fragmentation to various materials such as sandstone, ores, its crushing effect can replace in original iron ore crushing process the armamentarium from two-stage crushing to section grinding, simplify the technique of material fragmentation, by the progression setting of disintegrating machine and the rotating speed of rotating shaft, met the requirement to discharging particle diameter.When dividing plate is horizontally disposed with, material can be deposited in crusher chamber, forms a protective layer of avoiding newly entering material and liner plate direct collision; During the downward-sloping certain angle of dividing plate, material can not be deposited in crusher chamber, and material directly collides with liner plate, has improved broken effect and has saved the broken time simultaneously, and efficiency is higher.

Fig. 2 is the schematic diagram of the second version of a kind of vertical multi-stage super-fine crusher of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.
As shown in Figure 1, the first specific embodiment for a kind of vertical multi-stage super-fine crusher of the utility model, disintegrating machine comprises tubular shell 1, the upper end of housing 1 is provided with charging aperture 5, the lower end of housing 1 is provided with discharging opening, housing 1 lower end adopts open without grate type discharging opening in the present embodiment, the inwall of housing 1 is coated with one deck liner plate 8, the multi-layer annular dividing plate 6 that is provided with downward-sloping certain angle on liner plate 8 and extends internally, adjacent two dividing plates 6 surround one with housing 1 inwall and only have the open crusher chamber 7 of inner ring surface, the rotating shaft 2 of downward-extension is installed in housing 1, the upper end of rotating shaft 2 is connected with the motor of rotary power is provided for it, the lower end of rotating shaft 2 is by the rood beam support of housing 1 lower end, so neither affect discharging, also can provide support for rotating shaft 2.The outer tup fixed cover 3 being equipped with this rotating shaft 2 rotations of rotating shaft 2, tup fixed cover 3 outsides are fixed with tup 4, and tup 4 is staggered from top to bottom, in the present embodiment, at every layer of tup 4 that two intervals, 180 degree are set, staggered 90 degree of every two-layer tup 4 arrange.Tup 4, dividing plate 6 and liner plate 8 are made by known high-abrasive material, improve scuff resistance, increase the service life.Tup 4 matches with the position of the inner ring surface that crusher chamber 7 is opened, and concrete match-on criterion should meet tup 4 after clashing into material, can be squeezed into crusher chamber 7.
In use, first what broken and rotating shaft 2 rotating speed is basis selected to need to the requirement of discharging, as selected 7 grades of fragmentations in the present embodiment, there are 7 layers of tup 4 and 7 layers of crusher chamber 7, material is sent in disintegrating machine by charging aperture 5, atwirl tup 4 impacts material, and material is squeezed in crusher chamber 7, building stones and liner plate 8 clash into be pulverized, between material, also mutually clash into and pulverize simultaneously, after clashing into, material enters lower one deck under the effect of himself gravity, by tup 4, squeezed in crusher chamber 7 again, through the multistage material of shock repeatedly, by discharging opening, discharged, complete shattering process.Material after entering disintegrating machine through the impacting of tup 4, all can obtain crushing effect with the shock of liner plate 8 and mutual shock.
In the present embodiment, extend internally dividing plate 6 downward-sloping certain angles, the opening of crusher chamber 7 is tilted to down, so cannot survive material in crusher chamber 7, material with whereabouts, can improve broken efficiency with fragmentation like this, but the wearing and tearing that can strengthen liner plate inwall.The disintegrating machine of this form is applicable to the more place of rainwater.
As shown in Figure 2; for the second specific embodiment of a kind of vertical multi-stage super-fine crusher of the utility model, in this embodiment, the structure of the disintegrating machine in the structure of disintegrating machine and embodiment 1 is basic identical; difference is; dividing plate 6 levels extend internally, and the opening level of crusher chamber 7, more easily stockpiles material in crusher chamber 7 like this; make newly to enter material impacting on the material stockpiling; for liner plate 8 provides protection, make its more difficult wearing and tearing, but crushing efficiency declines to some extent than embodiment 1.The disintegrating machine of this form is applicable to the less place of rainwater.
Above-mentioned example is just for illustrating the utility model, and embodiment of the present utility model is not limited to these examples, and the various specific embodiment that meet the utility model thought that those skilled in the art make are all within protection domain of the present utility model.
