【 摘 要 】

References(12)Horizontal mechanically agitated vessels are widely used in mining enterprises. However, there is insufficient information about any direct relationship between the solid suspension and the impeller geometric parameters in a horizontal vessel. This paper presents a study on the effects of blade pitch angle on solid suspension in a horizontal vessel. The critical speed of solid suspension, Nc and power, Pc, were observed by independently varying both off-bottom clearance, C, and the blade pitch angle, θ to, give two correlations for each of the variables. Particle suspension experiments were also performed in a horizontal vessel with baffles and without baffles, and in a vertical vessel. The superior performance of a horizontal reactor without baffles is illustrated, comparing with a classical flat bottomed cylindrical reactor and a horizontal reactor with baffles.
