Abstract
The utility model discloses a novel four-roller impact crusher, which comprises a frame, a splitting pipe arranged at the top end of the frame, and an upper impact roller group installed inside the frame, wherein the upper impact roller group comprises two impact rollers working in cooperation. The novel four-roller impact crusher also comprises a lower impact roller group, wherein the lower impact roller group comprises two impact rollers working in cooperation, and the lower impact roller group is located just below the upper impact roller group and is parallel to the upper impact roller group. According to the crusher with the structure, the material is impacted multiple times in the crusher for crushing, and is directly crushed to be less than 6 mm by one crusher; and the crusher is compact in structure and small in occupied space.
Description
Technical field
The utility model relates to a kind of novel four roller impact crushers, belongs to crushing mechanism.
Background technology
Material for compression strength value≤150MPa; Fragmentation like coal, gangue, slag, coke, lime stone etc.; What present most industrial and mining enterprises generally adopted is that two-stage is broken, and the material with 300mm is slightly broken through encircling the hammer disintegrating machine earlier, carefully broken below 6mm through one impact breaker again; Not only have high input in advance, take up an area of extensively, and the later stage energy consumption is also big, maintenance cost is high.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and a kind of novel four roller impact crushers are provided, and energy consumption is less, and one feeding just can realize below the fine granularity 6mm.
To achieve these goals, the technical scheme of the utility model employing is:
A kind of novel four roller impact crushers, comprise frame, be arranged on the frame top sub-feed tube, be installed on frame inner go up counterattack roller group; Described going up strikeed back the counterattack roller that the roller group comprises two work that cooperatively interact.Also comprise counterattack roller group down; The described roller of counterattack down group comprises the counterattack roller of two work that cooperatively interact; Strike back down the roller group be positioned at counterattack roller group under, and parallel with last counterattack roller group.
As a kind of improvement, be provided with cutting plate in the described sub-feed tube; The cross section of said cutting plate is a triangle, and its top makes progress, and the bottom is downward.
Improve as another kind, described going up between counterattack roller group and the following counterattack roller group is provided with middle cutting plate.
As the another kind improvement, be provided with down cutting plate under the described roller of counterattack down.
Improve as another kind, described counterattack roller is provided with the system of moving back of dodging.
The usefulness of the utility model is:
Disintegrating machine with said structure, material in disintegrating machine through repeatedly impact, impact crushing directly is crushed to below the 6mm by a machine; Compact conformation, take up an area of little.Material through last, in two cutting plates, enter into each counterattack roller uniformly, the utilization rate that improves the counterattack roller has increased the number of times that material is impacted simultaneously; Following cutting plate is more even by discharging.Get into counterattack roller group as being difficult to broken material, dodge the system of moving back and can let the counterattack roller make a concession automatically, protection equipment is not damaged.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein: 1 is sub-feed tube; 2 is last cutting plate; 3 is frame; 4 are the counterattack roller; 6 is middle cutting plate; 7 for dodging the system of moving back; 10 are following cutting plate.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1, the utility model comprises frame 3, be arranged on the sub-feed tube 1 on frame 3 tops, be installed on frame 1 inner go up counterattack roller group; The described counterattack roller 4 that counterattack roller group comprises two work that cooperatively interact, the counterattack roller group under also comprising of going up; The described roller of counterattack down group comprises the counterattack roller 4 of two work that cooperatively interact; Strike back down the roller group be positioned at counterattack roller group under, and parallel with last counterattack roller group.Be provided with cutting plate 2 in the sub-feed tube 1; The said cross section of going up cutting plate 2 is a triangle, and its top makes progress, and the bottom is downward.Cutting plate 6 in being provided with between last counterattack roller group and the following counterattack roller group.Under be provided with down cutting plate 10 under strikeing back roller.The counterattack roller is provided with the system 7 of moving back of dodging.
During work, material by last cutting plate 2 separated into two parts, gets into two counterattack rollers going up counterattack roller group of rotation at a high speed through sub-feed tube 1 respectively; And with top bar impact grinding; After to be thrown to cutting plate 2 again broken once more, it is broken again to bounce back into the bar active region from last cutting plate 2 again then, again through in be divided into two parts after cutting plate 6 impact grindings again and get into down counterattack roller group and carry out impact grinding; Be crushed to desired particle size up to material, discharge by discharging opening.
