<p>PURPOSE:To eliminate the defective fluidization of a material to be granulated by controlling the velocity of a binder supply pump or the opening degree of a flow control valve on the basis of the water content of the material to be granulated detected by a water content detecting means provided in a fluidization chamber. CONSTITUTION:Hot air at a temp. regulated by a temp. controller is forced under pressure from a hot air chamber 12 into the fluidization chamber 1a in the main granulator body 1 through many through holes 13a provided to a gas diffusion plate 13, and the material to be granulated on the inside is fluidized. Meanwhile, purging air supplied from the main purge pipe 4a furnished to a detection cylinder 4 is passed through the detection cylinder 4 and blown on the fluidized material to be granulated in the vicinity of the opening part of the main ganulator body 1. Consequently, the powdery particles are not allowed to intrude into the detection cylinder 4 and practically moved the opening part.</p> |
