Pebble Lime Cooler

The Metso Pebble Lime Cooler, based largely on a previous L. H. Niems design, is a proven, efficient piece of heat transfer equipment.

Its primary purpose, along with that of its associated discharge feeders, is to cool the material discharging from the rotary kiln to a temperature that can be tolerated by the product take-away belt conveyor, all the while maintaining the material discharge rate required for the desired rate of lime production.

To accomplish this several PLC-based, “closed loop” (or automatic) control are employed.
