The vessel is filled until it is freely overflowing. The proper inflow of medium can be estimated to be 260 gallons/min for every foot of overflow weir length. For example, a 15 ft weir length vessel would require a dense medium flow rate of 15 ft x 260,Dense Medium Cyclone Plant, Coal Washing/Parnaby,Dense medium cyclones are used for very accurate separation of particles of different density. Particles smaller than 0.5mm are removed from the mixture before it enters the cyclone. Magnetite is added to the water/particle mixture to allow precise control of density. The dense medium cyclone is mounted at a 15° angle.
