Abstract
The utility model discloses a multistage ore crusher. The multistage ore crusher comprises a drum body, a rotating shaft and plate hammers, wherein the rotating shaft penetrates through the upper end and the lower end of the drum body vertically and is fixed on the drum body by a bearing seat; the top part of the rotating shaft is connected with a driving motor; the upper end and the lower end of the drum body are respectively provided with a feeding port and a discharging port; the plate hammers are radially distributed on the rotating shaft in the drum body and are axially and uniformly arranged along the rotating shaft to form a multistage crushing cavity. According to the multistage ore crusher disclosed by the utility model, the problems that the crushing mode is fussy and the crushed ore can not meet the requirement of fineness by one time in the existing ore crushing equipment are solved.
Description
Technical field
The utility model belongs to a kind of ore grinding equipment, is specifically related to a kind of multistage ore crusher.
Background technology
The products such as a large amount of jaw crushers that use of ore reduction now and circular cone are broken, the output of such disintegrating machine depends on relative area and the gap of processing machine processing part, and area is larger, and gap is more greatly that output is larger.But increasing relative area and gap can cause the size of the ore after disintegrating machine is processed also larger.The size inhomogeneous ore of prior art after for fragmentation will sieve to isolate the ore that size is different by sieve in addition, and the entrance that screening large ore out turns back to disintegrating machine again carries out for the second time or be repeatedly broken to reach required reduced size.
At present, in the mining processes real work, always require broken ore in the situation that the more tiny maximum production that obtains, now usually processing method is to adopt a series of disintegrating machine and vibration sieve, and the ore of extraction is connected by a plurality of disintegrating machines, by ore from be crushed to greatly, therefrom be crushed to little, therebetween by the screening needed trommel, the screening after underproof ore turn back to upper level carry out secondary and repeatedly the fragmentation, until arrive needed size.
The utility model content
Loaded down with trivial details in order to solve existing ore crushing equipment crumbling method, broken ore can't disposablely reach the problem of fineness requirement, and the utility model has designed a kind of multistage ore crusher.
The technical scheme that the utility model addresses the above problem is: a kind of multistage ore crusher, comprise cylindrical shell, rotating shaft, bar, rotating shaft vertically runs through the cylindrical shell upper/lower terminal, and be fixed on cylindrical shell by bearing block, the rotating shaft top is connected with drive motors, and the cylindrical shell upper/lower terminal has charging aperture and discharging opening, in the rotating shaft of bar radial distribution in cylindrical shell, and axially evenly distributed along rotating shaft, form the multiple stage crushing chamber.Its advantage is: ore enters in cylindrical shell from entrance, enter first order crusher chamber, after being subject to inner barrel being fixed on bar in rotating shaft and hitting under the effect of gravity, ore can produce multi-direction power, under the interaction force of multilayer ore, ore, easily from the fault location fragmentation, obtains high percentage of damage and produces more particulate products; Ore is after catching a packet, and the powerful fragment that ore produces in the shattering process kinetic energy that splashes carries out brokenly again to adjacent rock, make secondary energy obtain recycling; Ore after being impacted by bar slides along the bar surface, and strikes the liner plate surface, has carried out second-time breakage; Ore through second-time breakage, due to Action of Gravity Field, enter second level crusher chamber, and repeat above-mentioned broken program, and behind the multiple stage crushing chamber, ore reaches fineness requirement, then discharge from discharging opening, and marker size is reduced greatly.
Described multistage ore crusher, the nested liner plate of cylinder inboard wall, the liner plate inwall inwardly protruding between crusher chamber, form the ring-type guide ring.Its advantage is: the guide ring of projection, ore is guided in the next stage crusher chamber, and prevent that ore directly is slipped to cylinder body bottom from liner plate inside.
Described multistage ore crusher, the inwardly protruded height of guide ring is not less than the distance between bar and liner plate.Its advantage is: guarantee that ore all enters the next stage cavity, avoid ore to drain to cylinder body bottom from the space between guide ring and bar.
Described multistage ore crusher, bar is fixed in rotating shaft by rotor, has keyway in rotating shaft, and the rotor fixed card is connected in keyway, and bar is fixed on rotor by bearing pin.Its advantage is: rotor and bar are consumable accessory, can be convenient for changing bar and rotor in this way.
Described multistage ore crusher, cylinder body outer wall is shaft orientation reinforcing rib fixedly.Its advantage is: prevent cylindrical shell in the course of the work, because unbalance stress produces distortion.
Described multistage ore crusher, cylindrical shell is fixed by foundation bolt and the ground of bottom.Its advantage is: guarantee the stability of disintegrating machine when the course of work.
The utility model relates to a kind of ore reduction without sieve and grinds comprehensive one machine, its ratio of reduction on without the sieve situation once property complete and reach the 1--3 mm granules and account for more than 85%, below 1 millimeter, account for more than 50%, be 3-5 times of effect of existing equipment.

The specific embodiment
Below in conjunction with accompanying drawing, structure of the present utility model is explained in detail to explanation,
A kind of multistage ore crusher, as Fig. 1 is that the utility model partly cuts open structural representation; Comprise cylindrical shell 1, rotating shaft 2, bar 8, rotating shaft vertically runs through the cylindrical shell upper/lower terminal, and be fixed on cylindrical shell by bearing block 6, the rotating shaft top is connected with drive motors, the cylindrical shell upper/lower terminal has charging aperture 13 and discharging opening 14, in the rotating shaft of bar radial distribution in cylindrical shell, and axially evenly distributed along rotating shaft, form multiple stage crushing chamber 15.The nested liner plate 7 of cylinder inboard wall, the liner plate inwall inwardly protruding between crusher chamber, form ring-type guide ring 9.The inwardly protruded height of guide ring is not less than the distance between bar and liner plate.Bar is fixed in rotating shaft by rotor, has keyway 4 in rotating shaft, and rotor 12 fixed cards are connected in keyway, and bar is fixed on rotor by bearing pin.Cylinder body outer wall is shaft orientation reinforcing rib 11 fixedly.Cylindrical shell is fixed with ground by the foundation bolt 10 of bottom.
