 The SD™ Air Classifier represents a highly versatile, energy efficient system for the consistent separation of particles in the 100 to 400 mesh range.
Compact design allows easy retrofit into existing facilities. Saves on operating expenses: Low energy consumption. Durable, wear-resistant design minimizes maintenance. Effective product cooling. Consistent, high-quality product, regardless of variations in feed material, through easy-to-make changes in air flow and variable-speed rejector cage. Processes abrasive materials: ceramic liners and/or inexpensive, wear area replaceable liners available. Fines collected in cyclone or process collector.
