Air Classifier gives operators the ability to add significant value to the normally low value crushed rock fines by removing ultrafines to produce specification manufactured sand. This technology gives quarries the ability to produce dry engineered sand to a quality level that can meet the exacting requirements for both concrete and asphalt sands.
Dry mineral filler is produced as a by-product of the classification of engineered sands. This is the fine material that has been removed to achieve the sand specification and is collected from the dust collector. When this product meets local specifications, it is sold as an additive for bituminous paving mixtures, agricultural lime and other manufacturing processes.
Air classifier for mineral contains no moving wear parts. Unlike competitor air classifiers, the only purpose of the wear liners is to protect the classifier body so no adjustment for wear is required as all the work is done by the air. Other classifiers require their customers to make frequent adjustments when classifying abrasive material to try and maintain product specifications. The intelligent static design of the Air classifier translates to low total power draw, minimal maintenance and low operating costs.
Air classifier can be applied to processing of various materials having different physical properties. It can be successfully applied to the production of:
- mineral concentrates
- abrasive materials
- fillers for paper, rubber, paint and plastic
- raw materials for microelectronics
- raw materials for fibre optics
- advanced composite materials
- construction and building materials
- chemical industry materials
