Hydrocyclones AKA-VORTEX. Hydrocyclones are important and economically viable systems for the wet-mechanical separation and classifying processes of ores and minerals. AKA-VORTEX are applied across the industry in various areas: sorting, desliming, closed circuit grinding, solids recovery, classification.

1.. IntroductionThere have been several attempts focused on improving the washing of the sediment in the conical section of the hydrocyclone (Honaker et al., 2001, Udaya et al., 2004, Udaya et al., 2005).Tangential water injection into the cyclone cone has been applied to displace feed pulp water in the underflow stream and increase the …

In hydrocyclone H, the force keeps on a high magnitude level along the radius, however, an obvious weakened zone appeared near the wall in E and I, especially in I. Thus, hydrocyclone H provides the general higher classification force field in the upper cone section than E and I. The similar analysis can be carried out in the under cone, and …

GTEK Hydrocyclone Description. Hydrocyclone is a continuous device that utilizes centrifugal force to accelerate the settling rate of particles. When feed slurry enters the hydrocyclone tangentially under pressure, as result of the high centrifugal forces, particles coarser than the "cut point" size migrate into a primary vortex adjacent to the wall and …

The mica waste has a pH of 4.0 at Maggie Pie (2:1 mix- ture of waste to .01M CaC12) and a total-N content of 34 kg/ha in the surface

To fix this, increase the density of solids feeding the hydrocyclone, or decrease the size of the apex. The apex will be the fastest wearing part of most units. When the apex wears out, the opening gets larger, therefore allowing more water to go out the underflow. To fix this, replace the apex with a new one.
