A kind of liner plate of the extruding roller mill for break mined material material
The utility model relates to a kind of disintegrating apparatus parts, is specially a kind of modified for the liner plate of the extruding roller mill of break mined material material.
The extruding roller mill for break mined material material is in the market mainly used in lime stone, gypsum, in dolomite etc. in the fragmentation of rigid material, existing a kind of extruding roller mill for break mined material material, its operation principle is first large-scale material to be poured in body in crusher chamber, to utilize rotating shaft rotor driven to rotate collision broken material, material after fragmentation drops to the liner plate of crusher chamber and the broken material passage between hard tup, and be ground into fine particulate under the extruding of liner plate and hard tup, wherein the material particles of a lot of small volumes and powder are under hard tup crowded, through the through hole on liner plate and bottom lining plate, flow to tapping channel and drop in discharge bucket in advance, in addition, the fine particulate material by through hole again by under hard tup along not being milled into after less particle and powder with the plane of bottom lining plate, fall in discharge bucket, thereby complete the crushing process of material.In crushing process, as shown in Figure 4 because its through hole on the liner plate of existing extruding roller mill is vertical strip through-hole, in actual production process, with rotor high-speed, rotate, material after pulverizing is when the vertical strip through-hole by liner plate, tend to occur the situation of putty, cause discharging slow, had a strong impact on production efficiency.
Utility model content
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of extruding roller mill that makes to be difficult in the running occurring putty, liner plate that production efficiency is higher.
For addressing the above problem, the utility model provides a kind of liner plate of the extruding roller mill for break mined material material, described liner plate is arranged on the crusher chamber madial wall of extruding roller mill charging aperture below, on liner plate, have a plurality of strip through-holes, strip through-hole communicates with the discharge bucket of crusher chamber below by tapping channel; The trapezoidal strip through-hole that described liner plate strip through-hole is inclined type, the bottom surface outlet of liner plate strip through-hole communicates with tapping channel, and liner plate strip through-hole is downward and along the tangential tilt of the direction of rotation of rotor.
The beneficial effects of the utility model are: this device is on the basis of existing extruding roller mill liner plate, vertical strip through-hole on original liner plate is changed into the trapezoidal strip through-hole of obliquely-arranged, trapezoidal strip through-hole is downwards and along the tangential tilt of the direction of rotation of rotor, the centrifugal action that coordinates rotor high-speed rotation, comminuting matter enters material channel fast along through hole inclined-plane, strip through-hole is trapezoidal simultaneously, the less screening that does not affect material of upper bottom surface outlet, bottom surface outlet is convenient to more greatly material and is entered fast hopper.In this device production process, discharging is rapid, is difficult for occurring the situation of putty, has improved greatly production efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, with regard to the specific embodiment of the present utility model, be described in further detail, wherein:
Fig. 1 is the structural representation for the extruding roller mill of break mined material material;
Fig. 2 is the front view of the utility model liner plate;

Fig. 4 is existing liner plate A-A cross-sectional view;
In figure: 1-body, 2-crusher chamber, 2.1-charging aperture, the broken material of 2.4-passage, 2.5-tapping channel, 2.8-liner plate, 2.81-liner plate strip through-hole, 2.9-bottom lining plate, 3-main shaft, 3.1-upper bearing (metal), 3.2-lower bearing, 3.3-big belt pulley, 4-motor support frame, 5-motor, 5.1-small belt pulley, 6-belt, 7-rotor, the upper coaming plate of 7.1-, coaming plate under 7.2-, 8-spreading disk, 9-tup, 9.1-hammer handle, 10-discharge bucket.
The specific embodiment
With reference to a kind of extruding roller mill for break mined material material shown in Fig. 1, comprise body 1, body 1 below is connected with crusher chamber 2, in crusher chamber 2, be provided with charging aperture 2.1, the interior cross-under of body 1 has the main shaft 3 in crusher chamber of stretching into 2, body is provided with upper bearing (metal) 3.1 and the lower bearing 3.2 of main shaft 3 in two ends Shang Xia 1, the upper end of main shaft 3 is connected with big belt pulley 3.3, in crusher chamber 2, be connected with the motor rack 4 of accepting motor 5, the small belt pulley 5.1 being connected on motor 5 interconnects big belt pulley 3.3 by belt 6, main shaft 3 lower ends are connected with a rotor 7, rotor 7 comprises coaming plate 7.1 and lower coaming plate 7.2, upper coaming plate 7.1 and lower coaming plate 7.2 be arranged in parallel, upper coaming plate 7.1 and 7.2 of lower coaming plates are also welded with a plurality of hammer handles 9.1, on hammer handle 9.1, be fixed with tup 9,
The top that charging aperture is positioned at tup 9 for 2.1 times is provided with spreading disk 8, crusher chamber 2 medial surfaces of spreading disk 8 belows are provided with liner plate 2.8 and bottom lining plate 2.9, bottom lining plate 2.9 medial surfaces and and tup 9 between form narrow and small gap, 9 the broken material of common formation passages 2.4 of liner plate 2.8 and tup, on liner plate 2.8 and bottom lining plate 2.9, all offer a plurality of strip through-holes, strip through-hole communicates with the discharge bucket 10 of crusher chamber 2 belows by tapping channel 2.5.
As shown in Figure 2 and Figure 3, the trapezoidal strip through-hole that the liner plate strip through-hole 2.81 on liner plate 2.8 is inclined type, the bottom surface outlet of liner plate strip through-hole 2.81 communicates with tapping channel 2.5, and downward tangential tilt along rotor 7 direction of rotation is arranged on liner plate 2.8; Broken mineral material particle can flow out along the liner plate 2.8 that is provided with the trapezoidal strip through-hole of inclined type under the High Rotation Speed of rotor 7, by tapping channel 2.5, is transported in hopper 10.
The above; it is only the better specific embodiment of the utility model; but the utility model protection domain is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore the utility model protection domain is as the criterion with the protection domain of claims.
