Process and appliance for mixing materials in bulk

摘要

A process for mixing materials in bulk comprises the continuous and simultaneous withdrawal, through discharge openings distributed about the periphery of a mixing silo, of the material in such a manner that the vertical velocity of the descending material increases progressively about the periphery of the silo. Apparatus in accordance with the invention comprises a mixing silo having a relatively large number of discharge openings and means for insuring that the velocity differences in the material being withdrawn through adjacent openings is relatively small whereby the variation in material vertical velocity from the lowest to the miximum value will occur over a large number of discharge openings.
