Grinding Dust Collectors in Abrasives Industry - Grinding Wheels Manufacturer
A manufacturer of grinding wheels in Niagara Falls, N.Y., needed to
replace an existing dust collector used to collect dust coming off a rotary kiln. Initially, a bag house collector was considered to be the obvious solution. However, because the problem involved high temperatures - 700° F and higher - specific efficiency requirements, moisture content problems, and future maintenance issues, the purchase of an
Aerodyne SplitStream grinding
dust collector was justified.
The volume of gases being handled was estimated at 4,000 CFM at 700° F, according to the specifications of their previous cyclone. Using this information, a Model 4500 SplitStream
grinding dust collector was selected and installed. When the collector was started and the flows were checked, it was found that only 2,500 cfm at 500° F was needed to ventilate the kiln. Even at this lower-than-expected inlet flow rate, the results were excellent. No visible carry-over was detected, and the SplitStream Collector captured material much finer than previously collected. The plant was satisfied it had made the correct decision and avoided the headaches and maintenance issues of a bag house. After several months of the collector in operation, abrasion wear was not evident. Consequently, the company ordered two more Model 4500 SplitStream
grinding dust collectors.
The lack of a filter media and the Aerodyne's unique design make it perfect for applications involving high temperatures and abrasive materials.
