This dustless screening multiple stage crushing metering conveyer is mainly used in coal preparation plant's raw coal preparation system, the raw coal preparation system was made up of classifying screen, disintegrating machine, belt feeder, batcher, weighing balance in the past, this technology not only is organically integrated the said equipment, has following characteristics and advantage:
1, dustless screening, raw coal preparation system dust is big, and is difficult to solve, and influences environmental protection and the workman is healthy.It is independent generally all will to sieve fragmentation when coal preparation plant's technological design, to alleviate whole factory building is impacted.Its main cause is that coal classification time vibration on classifying screen causes.This technology has thoroughly solved this problem, and whole screening process carries out in airtight casing, does not externally have the dust from flying phenomenon, and has utilized area on the length of course of conveying, so grading effect obviously is better than traditional approach, and moves under low noise.
2, low vibration: vibration is mainly derived from classifying screen and disintegrating machine, classifying screen adopts the classification of non-vibrating roller drive transfer not have vibration problem, here disintegrating machine is owing to adopt the multiple stage crushing structure, so every grade fragmentation is loaded all, and first mate's degree alleviates, and every grade of all only broken granularity that is fit to fragmentation at the corresponding levels, therefore the more traditional crumbling method vibration of vibration reduces significantly.
3, reduce civil engineering costs: traditional classifying screen and disintegrating machine are considered space for maintenance, generally need height more than 5 meters, because this technology will be sieved, shattering process is superimposed on the conveyer, this height space no longer needs, so civil engineering costs reduces.
4, be easy to maintenance: owing to adopt modular structure, the weight of single parts also greatly alleviates, and is easy to safeguard.
5, add reciprocal feeder and appearance formula metering device at tail, with metering, coal supply, transportation, classification, broken instant be one, having solved dust, vibration, maintenance, building height problem again is the inventive point of present technique.
