Title Horizontal double shaft paddle mixing machine            

Abstract

Mixing machinery currently develop rapidly in our country, and there are all kinds of them. Biaxial horizontal mixer, which has a compact structure, good sealing, the inlet has blocked gray boards, to prevent the mist playing; stir, stirring blades fan-shaped contact with the media area of the stirring time and other characteristics, is the industry leader in science and technology nowadays. As a highly efficient mixer, its performance is extremely stable, stirring effect, continuous production, easy maintenance, and can be adapted to the various components of the stirring, versatility. 

This paper analyzes the mixer principle, on the basis of existing research on the mechanical structure of the mixer, by calculating design a line with a new horizontal mixer required to determine its structure optimization, finite element and its key parts of the performance analysis. This machine also has convective mixing, shear mixing, dispersive mixing mixing effect, mixing uniformity largely improved. 

Keywords Horizontal-axis; Mixing principle; Structural Design; Performance Analysis
