Aerosplit Classifiers
Features
The Aerosplit range is suitable for processing dry particulate materials and is capable of handling quantities from a few kilos/hour up to many tonnes/hour. These high efficiency, airswept forced vortex units are designed to operate either in closed-circuit with a conventional milling system or as independent “stand-alone” systems incorporating feeder, fan and product collection equipment. The Aerosplit can be installed in existing air systems with a minimum of modification and will separate products of exceptional fineness and uniformity over a wide range of feed variations.
• Operating range of 3 to 150 microns.
• Available in a range of sizes with capacities from a few kgs/hour to many tonnes/hour.
• Excellent sharpness of cut.
• Precise on-stream control of cut point by variation of rotor speed.
• Low system resistance.
• Low power consumption.
• Adjustable secondary air system for optimisation of classification efficiency.
• Design configuration ensures feed material immediately enters the classifying vortex unimpeded by re-circulating coarse fraction giving superior performance.
• Optional linings.
• Ceramic rotors may be fitted where necessary.
• Operates under suction promoting dust-free environment.
• Robust construction and build quality for long service life.
• Mild steel or stainless steel construction available.
• Optional, abrasion resistant linings available in steel, rubber, polyurethane or ceramics.
Operating Principles
• Entrained feed material enters through primary air duct (1).
• Particles are introduced into a forced vortex generated within the machine by a rotor (2).
• Particles are classified within the vortex as a result of the interaction between centripetal and air drag forces.
• Cut point determined by control of rotor speed (and air flow).
• Particles below cut size pass through the rotor and exit with the entraining air duct (4) for collection in the external system.
• Coarse particles above the cut point migrate to the casing wall and descend through the discharge cone (3) to outlet.
• Secondary rinsing air enters through duct (5) dispersing agglomerated fines giving improved product yield.
• Secondary air flow rate controls the residence time within the separating zone and can be adjusted to give optimum classification conditions for widely differing materials.
