Cyclones Don''t Do Any Grinding

2017-10-10 · If the pressure goes too high before a cyclone is added the cyclones will rope forcing coarse material out the overflow (grit) relieving the circulating load. If the system operates close to the limit the operators may not even notice this is happening, often only one cyclone (the least worn) will rope bleeding coarse material out of the circulating load into the overflow.

To avoid blockages in the cyclone inlet, it is recommended that the 95% passing size of the feed not exceed (0.05 x DC). Therefore, in the example, the cyclone diameter should be at least (30 mm/0.05) = 600 mm. Thus, for a 610 mm cyclone, the inlet diameter will be (0.2 x 610 =) 122 mm.
