3 times.
Above-mentioned modularization multi-chamber continuous kneader has a pair of of blade, each blade and corresponding chamber in the chamber
The upper lower half circle of room is coaxial, and the minimum clearance between each pair of blade is 3 times of solid phase particles partial size；The blade is in axial direction
Torsion, wherein the blade of semicircle on the chamber is right hand helix, the blade of lower half circle is left hand helix, each pair of incorgruous rotation of blade
Turn, also provide tangential force to material while mediating to material, pushes material to lateral movement, into next chamber
Room；The blade of the discharge chamber is dumbbell shape, provides bigger lateral thrust to material and releases material from discharge port；It is each
A blade has spline by transmission device independent control, the blade tail end, for connecting transmitting power with transmission device.
Above-mentioned modularization multi-chamber continuous kneader, the bracket are fixed on each chamber lower end, bracket by screw
Lower end is dove-tail form, convenient for installing with guide rail, threaded hole is provided in quadrangle, for fixing with guide rail.
Above-mentioned modularization multi-chamber continuous kneader has dovetail groove in the guide rail, and the length every a chamber opens waist
Type through-hole, for positioning and fixing with corresponding bracket.
