Three-way cross-excitation disturbance method forced granulator

Abstract

The invention discloses a three-way cross excitation type forced granulator with a disturbance method, which comprises a cylinder, the cylinder rotates around its own axis, and an exciter arranged eccentrically inside the cylinder, and the exciter revolves around its own axis Rotate, and the direction of rotation is opposite to the barrel; the exciter includes a disturbance excitation plate whose surface is perpendicular to the axis of the exciter, and the disturbance excitation plate includes a plurality of plates arranged around the circumference, and the direction of the plates is The exciter turns to the same side and is thinner than the other. The three-way cross-excited disturbance method forced granulator of the present invention has the advantages of simple structure, good granulation effect, high granulation output and the like.

Description

technical field [0001] The invention relates to the field of granulation machinery, in particular to a three-way cross-excitation forced granulator with disturbance method. Background technique [0002] Commonly used powder granulation equipment in the prior art includes a cylinder granulator and a pelletizing disc. [0003] The cylinder granulator arranges the hollow cylinder obliquely and makes it rotate around its own axis. The material enters from the higher end and rolls to the lower end by gravity. The principle of the cylinder granulator is to rely on raising the material accumulation angle to make it larger than the repose angle, causing the material pile to collapse, causing the material to slide down along the collapse surface, and complete the particle growth during the sliding process to achieve granulation, such as figure 1 shown. With this granulation principle, the granulation movement obtained by the material during the granulation process is weak, and only...

AI Technical Summary

Problems solved by technology

Since the granulation of the pelletizing disk depends on the rolling of the material along the bottom surface, the strength of the ball forming movement is greatly affected by the distance between the material and the bottom surface. When the distance between the material and the bottom surface of the pelletizing disk exceeds 100mm, the granulation ability almost disappears, so , although the pelletizing disc has a strong ball-forming movement, the output is low and it is difficult to meet the requirements of mass production
