| Description |
In India, a major portion of metallurgical coal of desirable ash is produced from the dense medium cyclone (DMC) process. Based on detailed laboratory studies, vorsyl separator (VS), a centrifugal dense medium separator, was established to be a possible alternative to the dense medium cyclone. To establish further at commercial scale, trials were undertaken with 400 and 600-mm vorsyl separators made of mild steel, at the captive washeries of the Tata Iron and Steel. The studies clearly showed that the VS gave about 4% higher combustible recovery compared to a DMC at the same ash rejection level. Generalised Ep value of 0.033–0.045 for VS was also found lower compared to 0.043–0.068 for DMC. This clearly established the better sharpness of separation in VS compared to DMC. Vorsyl separator made of suitable wear-resistant material is recommended for regular plant use.
