Lime feeder simultaneously meters and conveys lime to pH neutralization tanks and pools from silos, bulk bags, 50-pound bags or any source. Equipped with AC or DC variable speed drives, it conveys lime vertically, horizontally or at any angle; over short or long distances; over, under or around obstructions. The rugged flexible screw is the only moving part contacting lime, minimizing maintenance. It is available integrated with bulk bag unloaders, bag dump stations, silos, or other lime storage containers or vessels, and is inexpensive to purchase and operate. Other lime-handling equipment for wastewater applications offered by the company includes bulk bag unloaders, bulk bag conditioners, bag dump stations and plant-wide bulk handling systems.
