It is based on the design theory of the turbine machinery and the particles' motion characteristics in turbo air classifier. The logarithmic spiral volute profile can be expressed as the following formula: R = R h e Q 2 π bR h V ht φ. Both the continuous phase and discrete phase simulations indicate that the logarithmic.

Air classifiers can handle a variety of fine as well as coarse powders like cement, alumina, inorganic chemicals, limestone, plastic particles, fine chemicals, and pharmaceuticals. The equipment in Figures 12.3(d) and 12.3(e) employ devices that throw particles into an air space from which the finer particles are removed and subsequently …

Classification & Separation. Hosokawa's classifiers are engineered to meet industry's increasing need for finer particles and more narrow particle size distribution. Our classifiers are designed to consistently produce particle size distributions that are: uniform and homogeneous; spherical and smooth and dry and easily dispersible.

The influence of air classifier wheel speed on pea protein enrichment was studied (Pelgrom et al. 2013) by increasing the wheel speeds from 5000 to 12,000 rpm that resulted in reducing the mean particle size diameters (D 50) of the fine fractions (from 8.8 to 4.8 μm) and coarse fractions (from 23.7 to 19.2 μm). The protein content of the fine ...

The feed rate of the air classifier is in range between 2 and 6 kg/h, which is the function of bulk density. Rotor speed varies between 2500 and 15,000 rpm and air flow rate is in range between 5 and 30 m 3 /h. The target size of the classification can be adjusted with the air flow rate and rotor speed.
