Description
Technical field
The invention belongs to the disintegrating machine technical field, the full round angle impact breaker of a kind of low carry of saying so more specifically.
Background technology
Impact breaker (it is broken to be called for short counterattack) is a kind of muck equipment of novel efficient, its characteristics: be volume is little, and simple structure; The ratio of reduction big (can reach 40), production capacity is big; Product granularity is even, is the square and the corner angle of pruning, and promptly has the shaping feature to product particle.Along with the development of Building Trade in China, shaping building stones demand is increasing year by year, so the demand of impact breaker is also increasing year by year.
Impact breaker utilizes the high speed rotor rotated that the material of knocking down in the crusher chamber is produced high speed impact, materials casting to counterpunch board, material is fallen by gravity and bounce, but the high speed rotor rotated drives bar tangentially clashes into material once more, material is thrown to another piece counterpunch board, material is by further broken, then again from the counterpunch board bar that rebounds, said process constantly repeats, in this process, be subjected to the strike of bar, the impact and the material collision each other of counterpunch board owing to material, material constantly produces the crack, until loose pulverizing.When raw meal particle size during, just drawn off crusher chamber less than the discharge slit between counterpunch board and the bar.The broken superiority of counterattack is that it utilizes the smashing principle that hits at a high speed and repeatedly repeat to strike back, make the material after the fragmentation more be accurate square, and the corner angle of pruning, the building stones that are used for the GOOD TASTE of Cement Concrete in building trade, be to select for use impact breaker to make the finished product material that last road fragmentation is finished mostly, this function is also referred to as shaping feature.And the broken maximum shortcoming of counterattack is: the big abrasion of power consumption are high, promptly the disintegrating machine with other types is (broken as jaw, circular cone is broken) compare, its cost is wanted high several times, and (bar and counterpunch board are easy to wear especially, especially broken hard ore, it is then even more serious to wear and tear), this also is because it hits and strike back many times the intrinsic disadvantage of being brought with the high speed of material.
The feeding-passage of prior art impact breaker all is arranged on rotor axis top, contacts with rotor upside position earlier after the charging, and the patent No. is that the structure shown in two kinds of impact breakers of 03282600.1 and 200520047549.2 is all like this.This structure inadequate natural endowment is: 1. raw material enters from strikeing back brokenly the top feeding-passage, at first with directly over the rotor begin to contact, do strike-counterattack-strike-counterattack then ... broken, under the rotor that runs up drives hurriedly and mistake, material holdup time in crusher chamber is short, and the counterattack number of times is few, and can not control the holdup time, and the performance of shaping feature is relevant with the number of times that hits, strike back.2. from (accounting for whole rotor 1/4 girth) below the rotor centerline in 90 ° of scopes of a reverse side, be broken blind area, this zone is not produce broken work done, and this is structural waste, is the broken major defect of prior art counterattack.
The feeding-passage lower end is arranged on the rotor top, so directly reduced the covering space of counterpunch board, building stones are from the feeding-passage input, only in less than 180 ° interval, produce bump, hurriedly and therefore mistake causes the holdup time of material in crusher chamber short, the counterattack number of times is few under the rotor that runs up drives, building stones are just little by the probability of bump shaping, and the direct result of bringing like this is the shaping inefficiency.

Technical characterictic of the present invention is:
1. low carry, material under the prior art is to contact with the upper part with the horizontal center line of rotor earlier, the broken work done process of " bump with counterattack " then, the present invention is improved to elder generation and contacts with the following position of rotor horizontal center line, material is thrown from the bottom up, entered the broken work done process of " bump with counterattack ".
2. full round angle is because the present invention contacts fragmentation, the broken blind area of having eliminated prior art earlier with material with the following position of rotor horizontal center line.Like this, make the present invention realize the full round angle of the rotor impact crushing of participating in the overall process, improved the utilization rate of device structure.
3. can control, the present invention has set up a control panel (control panel also be counterpunch board simultaneously), and original feeding-passage position in the prior art exactly, the position that control panel is set also is that original material begins broken starting point.From in essence, the present invention is to have shifted to an earlier date 90 ° of zones with the broken starting point of material, material is from just clashing into below the rotor horizontal center line, strike back after material thrown control panel from the bottom up, this process is the single stage crushing process that increases newly among the present invention, and the impact crushing later from control panel is identical with the prior art impact breaker.
