Application

Quarry, Southern England. Pulse-jet unit with 228 bags; air-to-cloth ratio 4/1.

Optimization Potential

The stearic acid used to coat the surface of the carbonate particles caused conventional filter bags to blind within three days. A 12" w.g. pressure drop was reached. Several bags were removed, and the unfiltered air was vented into the atmosphere.

Solution

A full set of 228 GORE® membrane/Nomex® felt filter bags was installed

Results

High production levels and low pressure drop. Increased mill efficiency yielded considerable energy savings by producing a set tonnage in a much shorter period. The excellent cake-release characteristics enabled the collector to be operated continuously for 12 months at a maximum pressure drop of 5" w.g. The emission problem was eliminated.
