Description

Double-roller crusher

Technical Field

The utility model relates to an environment-friendly production technical field, concretely relates to double-roll crusher.

Background

The refractory castable is prepared by taking corundum as aggregate and adding a plurality of bonding agents to powder. Has higher mechanical strength, abrasion resistance and other properties than high-alumina refractory castable and mullite refractory castable, but has slightly poorer thermal shock resistance. The material is mainly used as the lining material of various kilns such as boilers, blast furnace hot blast stoves, heating furnaces, ceramic kilns and the like.

The double-roller crusher is suitable for coarse and medium-grade crushing of brittle blocky materials in the industries of cement, chemical industry, electric power, mine, metallurgy, building materials, refractory materials, coal mine and the like.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a roll crusher can carry out the breakage to the large granule wherein before the roll crusher, increases crushing effect.

In order to solve the technical problem, the utility model adopts the following technical scheme:

to roller crusher, including broken case, the feed inlet has been seted up at broken roof portion, and the cavity body of discharge gate is seted up to the bottom both sides, and the inherent feed inlet bottom of broken case is provided with relative pivoted crushing roller, is provided with the feeder hopper on the feed inlet, is provided with broken sword in the feeder hopper, and two broken swoves rotate relatively.

Furthermore, a first material homogenizing plate and a second material homogenizing plate are respectively arranged at the lower part of the feeding hopper in the crushing box, blanking ports are formed in two side walls of the first material homogenizing plate, and the second material homogenizing plate is obliquely arranged between the two crushing rollers.

Further, the side wall of the crushing box at the upper part of the second refining plate is provided with an air outlet pipe, and an exhaust fan is arranged on the air outlet pipe.

Further, the bottom of the crushing box is provided with a discharging plate, and the discharging plate is obliquely arranged from the middle to the two discharging openings.

Further, the crushing roller and the crushing knife are driven by an external motor.

Furthermore, the side wall of the crushing box comprises an inner wall and an outer wall, a cavity is formed between the inner wall and the outer wall, and anti-collision cotton is arranged in the cavity.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model discloses earlier carry out the breakage through broken sword, then use the crushing roller to carry out breakage, can increase crushing effect.

2. Be provided with first homogenizing plate and second homogenizing plate, can slow down the input speed, increase crushing effect.

3. Be provided with outlet duct and air exhauster, can absorb the dust that produces and get rid of, reduce broken incasement dust, increase operational safety nature.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure, 1-crushing box, 2-feeding port, 3-discharging port, 4-crushing roller, 5-feeding hopper, 6-crushing knife, 7-first material homogenizing plate, 8-second material homogenizing plate, 9-exhaust fan, 10-discharging plate, 11-anti-collision cotton, 12-blanking port and 13-air outlet pipe.

Detailed Description

As shown in fig. 1, in order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

To roller crusher, including broken case 1, feed inlet 2 has been seted up at 1 top of broken case, and the cavity body of discharge gate 3 has been seted up to the bottom both sides, and the intrinsic 2 bottoms of feed inlet of broken case are provided with relative pivoted crushing roller 4, are provided with feeder hopper 5 on the feed inlet 2, are provided with broken sword 6 in the feeder hopper 5, and two broken sword 6 rotate relatively, carry out the breakage through broken sword 6 earlier, then use crushing roller 4 to carry out breakage, can increase crushing effect.

Example 2

On embodiment 1's basis, feeder hopper 5 lower part is provided with first homogenizing board 7 and second homogenizing board 8 respectively in broken case 1, and blanking mouth 12 has been seted up to first homogenizing board 7 both sides wall, and second homogenizing board 8 sets up to the department slope between two crushing rollers 4, can slow down feed rate, increase crushing effect.

Example 3

On the basis of embodiment 2, the side wall of the crushing box 1 on the upper part of the second material homogenizing plate 8 is provided with an air outlet pipe 13, and the air exhaust fan 9 is arranged on the air outlet pipe 13, so that generated dust can be absorbed and removed, the dust in the crushing box is reduced, and the operation safety is improved.
