Pulse Jet Dust Collector has been successfully used to collect limestone dust at this processor. The unit uses a special settling chamber designed to eliminate the need for a cyclone pre-filter, which is traditionally employed in similar heavy loading applications. Instead of a cyclone, dust enters the collector via a high side inlet which reduces the settling velocity, letting the dust drop out of the air stream. With less suspended dust, wear on the filter bags is reduced.The pulse jet vents a rotary limestone dryer. Air volume is 16,860 ACFM at 187fF; air-to-cloth ratio is 5:1. By eliminating the cyclone, the collector has also reduced the total system pressure drop, and eliminated cyclone maintenance and cyclone space considerations.
