Targeting at design and manufacturer of heavy media cyclones in India as a step further in offering complete washery solutions. Highly in-demand in the coal washing industry. Operating Principle Gravimetric separation takes place in the heavy media cyclone due to the buoyancy effect of the media forcing the lighter solids to the outer periphery of the HM Cyclone where they are transported upward and through the vortex finder. The dense mineral matter spirals toward the apex and exits through the orifice. Typically these cyclones can process minerals up to 70 - 80 mm size but work very well with smaller size particles down up to 0.1 mm. Material of Construction The material of construction in a cyclone is one of the most important factors that affect the efficiency of the cyclone. The next important factor is to determine the best combination of options available like the inlet shape, the entry of the slurry, the barrel section length and the size of the bottom cone of the cyclone. The outer shell of Cyclones is fabricated from mild steel. The inner surface is lined with the different material depending on the application. a) Adequate thick rubber lining where fine particles with not much abrasion is processed. This lining gives the best performance owing to its very smooth profile. For low ash coal and iron ore etc. The rubber used is specially treated for such applications. b) 25mm to 50 mm thick engineered ceramic lining in applications where highly abrasive material is processed. Applications a) Coal Beneficiation Plants. b) Mineral Processing Industries e.g. Diamond, Copper, Gold etc. c) Very popular in coal washing industry and many other mineral processing industry like diamonds, copper, gold etc where minerals are gravity separated.
