IIT unveil new c-series air classifiers

Low-energy classifiers developed for mineral processing and quarrying applications
International Innovative Technologies (IIT) have added a new range of air-classifiers to their existing line of specialist bulk solids and powder-handling equipment.
The c-series units are specifically designed to tightly control the particle size distribution of finer products and for cut-points in the range of 10–160 microns. Some models can be used effectively for finer material applications.
The robust, high-throughput air-stream units can accommodate the requirements of most fine powder production applications and are capable of maximizing separation efficiency without compromising system energy requirements.
The c-series construction comprises a classifier body and wheel, which are aerodynamically formed to reduce system pressure drop, maintaining the power demand of the system fan at an optimum level. Additionally, unlike other designs, IIT’s c-series classifiers have no secondary airflow requirement, which can increase power consumption and affect system efficiency.
As a result, the advanced design of the new range of classifiers ensures that particle size remains consistent under steady state conditions. Particle size cut-point changes are also easily controlled by a smooth, stepless adjustment of the classifier wheel speed during operation – the higher the wheel speed, the finer the product.
To cope with the demands of the most abrasive powders, the classifier wheel blades are made from specially hardened steel to reduce attrition. ATEX-rated models are available for use with hazardous materials.
The new c-series classifiers are also available for standalone particle sizing applications and can be supplied as part of complete material processing solutions in combination with IIT’s complementary s-series cyclones and m-series milling units.
