An improved vane of the type adapted for use in the classifier cage of a bowl mill type coal pulverizer. The improved vane is designed such that its lower end extends below the classifier cage inlet when the vane is mounted in the inlet. In a preferred form, the vane has a generally trapezoidal shape with a longer lower edge. The vane is additionally bent …

The most suitable condition is baffles angle of 20° and inlet velocity of 19.3 m/s considering the load of the mill and the fineness of the pulverized coal at the inlet of the classifier. View ...

Simulation studies showed that classifier blade length of 313.94 mm at 40° was found to be optimum, with 71.5% of particles passing fine size sieve (75 μm) and 0.1852 sharpness of cut. Classification of fine coal by the optimum classifier model is improved by 10%, as compared to original classifier model used in industry.

The coal particles on 50 mesh were reduced by over 60% and on 100 mesh, by over 50%. The mill power only increased by 4.4% and stayed within the capability of the existing …

Experiments were conducted at air flow rates of 1.41-1.71kg/s and air fuel ratios of 4.8-10 with classifier vane angle adjustment (30°- 60°) and inlet swirl umbers (S) of 0.49 – 1. Radial profiles of tangential, axial and radial velocity were obtained at several cross sections to determine the airflow pattern and establish links with the ...

mass flow rate of coal from the mill for coal particle size i. As a result, for the new design analyses, certain steps are going to be checked and controlled. These steps are as follows: • The coal mass flow rate from the mill should be approximately 10.0 kg/s, as in the D-00 base case. •

The combination of a modiftiation of the vortex finder and the vane angle, Sc vane-vortex, pushes the exiting particles deepest into the classifier, resulting in the highest likelyhood that large particles will be captured. The percentages of product particles that penetrate down below 0.8 m is zero in all scenarios.

However, the guide vane of a 15° setting angle should be optimized due to the non-uniform airflow circumferential distribution in the annular region. To obtain a well-distributed flow field of a turbo air classifier, a design method for the guide vane is provided based on the airflow trajectory in the volute and a new guide vane of a 10 ...
