Increasing the force on the particles demands more energy, which Clark says comes in terms of pressure drop across the cyclone. "For cyclones in the wood industry, whether it's for a pellet dryer or other application, there is a practical limit to the amount of energy one can apply to meet environmental standards," Clark says.
Mesh model of cyclone p Pa 221.52 223.36 Page 13 Volume IV, Issue VI, June 2015 IJLTEMAS ISSN 2278 - 2540 From above fig.7 it is been observed that the pressure drop is more for single inlet cyclone than symmetrical inlet cyclone. Means the pressure drop is depending on the inlet velocity for the same model.

present investigation the characteristics of flour mill cyclone are studied for various flow rates (inlet velocities) and its effect on performance parameters like pressure drop and efficiency are studied. Cyclone is designed with two symmetrical tangential inlets and a single tangential outlet at the barrel top area where impeller is mounted.
Krebs Engineers approach cyclone design similar to screen design. Cyclone design is based on the d50(c) achieved using a typical cyclone under standardize conditions, i.e., Medium = water at 20 °C & 1 centipoise; Solids density= 2.65; Solids concentration < 1%. Pressure drop = 10 psi. The base d 50(c) can be estimated by the expression:

This pressure gradient, combined with the frictional pressure losses at the gas inlet and outlet and losses due to changes in flow direction, make up the total pressure drop. - The pressure drop, measured between the inlet and gas outlet, is usually proportional to the square of gas flow rate through the cyclone. -

4.3 PRESSURE DROP The cyclone pressure drop is a function of the cyclone separator dimensions and its operating parameters. The pressure drop over a cyclone is caused by the change in the area, wall friction, change of the flow direction and the dissipation in the vortex finder (outlet tube). In general, the term 'pressure drop' means
flow rate and pressure drop over the cyclone. An empirical model using the variables mentioned above was obtained using data collected by the data historian. [1] Where %+300 = particle size in cyclone overflow (µm) F = volumetric flow rate (m3/hr) P = cyclone pressure drop (kPa) D = slurry feed density (kg/m3) ki, x,y,z = constants Gain = constant

a cyclone. These parameters are inlet velocity, pressure drop and collection efficiency of the cyclone. An accurate prediction of cyclone pressure drop is very important as it relates directly to operating costs. Variation of entry velocities to the cyclone results in variable collection efficiencies for a given cyclone, with a decrease
