Description

Jump bit classification pulverizer

(1) technical field:

The utility model relates to a kind of ore reduction machinery, relates in particular to a kind of jump bit classification pulverizer.

(2) background technology:

At present, the mechanical type that is used for ore reduction is a lot, and what wherein obtained extensive use is squash type grog disintegrating machine.China utility model patent specification CN2404591Y discloses a kind of " high speed squash type clinker pulverizer ", it comprises rotor, casing, liner plate and transmission device, its rotor is made of main shaft and the handle, the extrusion head that are vertically fixed on the main shaft, inwall is equipped with liner plate around the cylindrical shell, below liner plate, form a horizontal ring plain by a hook-shaped bending, gap between this horizontal ring plain and extrusion head, the liner plate forms the space of relative closure, and transmission device is made up of bearing and belt pulley, motor etc.When treating that broken material enters the space of above-mentioned relative closure, under the atwirl drive of rotor, extrusion head high speed pressing materials is pulverized it, and the material after the pulverizing falls into the casing bottom and draws off from discharging opening.Be somebody's turn to do " high speed squash type clinker pulverizer " though broken material is very effective, but it can only be broken into smaller particles with about 80% of material in the machine, and whole materials all can't be broken into granule, that is to say, it can not control out the grain graininess of machine material fully, has therefore influenced its further promotion and application.

(3) summary of the invention:

Technical problem to be solved in the utility model just provides a kind of jump bit classification pulverizer, it has overcome the problem that existing pulverizer can not be controlled out machine material particles granularity fully, by the mode of sorting material in the machine, the controllable granularity of using the machine material is built on request and in a certain size range of setting.

In order to solve the problems of the technologies described above, the technical solution that jump bit classification pulverizer of the present utility model is adopted is such: it comprises casing, liner plate, horizontal rotating disc, jump bit, transmission device, space between liner plate and the jump bit is a crusher chamber, one horizontal ring-type sieve plate is installed below liner plate, on the discharging opening below the jump bit cage rotor is installed, cage rotor is fixed on by an end on the base plate circumference of horizontal rotating disc and the rod iron that its whole radial of the horizontal ring-type sieve plate of the unsettled sensing of the other end is arranged is formed.

After adopting technique scheme, the utility model is under the driving of transmission device, horizontal rotating disc will drive jump bit with the cage rotor fast rotational, after material enters crusher chamber, owing to the intense impact of the hammer that is hit is pulverized, a part of fines will fall by the sieve aperture of horizontal ring-type sieve plate in the pulverizing material, and most of material of pulverizing can be fallen and impacted by rod iron on the cage rotor and disperse, wherein fines is because little final can the falling by cage rotor of inertia, the coarse granule material is impacted the crusher chamber continuation fragmentation of rebounding because inertia is big, thereby reaches the purpose of stock grading.When the invariablenes turning speed of horizontal rotating disc was constant, the sieve aperture of horizontal ring-type sieve plate was more little, and the rod iron spacing of cage rotor is more little simultaneously, and to be that rod iron is arranged close more, and going out the machine material will be thin more.The utility model can be controlled out the grain graininess of machine material by the grading of horizontal ring-type sieve plate and cage rotor, can satisfy industrial meticulous requirement to the material fragmentation, and simple in structure, the reliable operation of this machine, helps promotion and application.

(4) description of drawings:

Fig. 1 is the structural representation of the utility model jump bit classification pulverizer.

(5) specific embodiment:

As seen from Figure 1, the utility model jump bit classification pulverizer includes the casing 1 of the oblate box-like shape that steel plate makes, inwall is equipped with the liner plate 2 that antifriction alloy is made around casing 1, casing 1 top is provided with the transmission device of being made up of motor, belt pulley, bearing, vertical shaft, and the horizontal rotating disc 3 of steel is fixed on the lower end of vertical shaft; Be shaped on access door around the casing 1, with parts in the machine of being convenient for changing.Around horizontal rotating disc 3, with the equally distributed form of equal intervals several jump bits 4 are installed, jump bit 4 usefulness antifriction alloys are made, and its quantity is 6-24.Space between liner plate 2 and the jump bit 4 is a crusher chamber.A horizontal ring-type sieve plate 5 is installed below liner plate 2, and horizontal ring-type sieve plate 5 is made by wear-resisting steel plate, and the sieve aperture of slit shape is arranged above it, and the width of sieve aperture is 3-30mm.Discharging opening is provided in a side of the below of jump bit 4, the ring-type hole between the interior bead of promptly horizontal ring-type sieve plate 5 and the outer bead of horizontal rotating disc 3.A cage rotor 6 is installed on the discharging opening, cage rotor 6 is made up of some rod irons, one end of rod iron is fixed on the base plate circumference of horizontal rotating disc 3, and the horizontal ring-type sieve plate 5 of the unsettled sensing of the other end, its integral form are the arrangements of radial outside horizontal rotating disc 3 circumferential.The cross sectional shape of forming the rod iron of cage rotor 6 can be circular, also can be square and rectangle, and the quantity of rod iron is between 10-1000.The rod iron of liner plate 2, jump bit 4, horizontal ring-type sieve plate 5 and composition cage rotor 6 all should be designed to dismountable form, so that can in time change after the wearing and tearing.
