Working principle of double screw mixer mixer_News_reactor | jacketed reactor | stainless steel reactor

The revolution of the double helix cone mixer makes the powder make a circular motion along the cone wall. The rotation of the helical blade makes the powder discharge radially to the center of the cone. The powder is discharged from the cone to the upflow and the outer circumferential surface of the spiral, that is, the mixing in the direction of the spiral axis. The combination of the revolution and rotation of the screw in the mixer results in four flow forms of the powder, that is, the compound movement of convection, shear, diffusion and infiltration. Therefore, powder materials can be quickly and uniformly mixed in this mixer.

Double helix cone mixer/advanced structure, easy operation, safe and reliable operation, no bottom bearing for the screw shaft, it eliminates the failure caused by the leakage of powder from the bottom bearing. The agitator is asymmetrical arrangement of double helixes, one large and one small expand the stirring range, so it is more suitable for mixing materials with different proportions and special mixing ratios. The mixing process is mild, and the material will not produce pressure feed, wear, and overheating.

DSH series conical mixer/two asymmetric spirals in the barrel rotate to lift the material upward, and the rotating arm revolves at a slow speed; the material outside the spiral enters the stud to different degrees, so as to achieve continuous renewal and diffusion of the material in all directions. , the two materials raised in the upper part converge to the central cavity to form a downward material flow, which supplements the vacancy at the bottom, thus forming a triple mixing effect of convection circulation; the standard conical screw mixer has two In practice, according to the size of the equipment, single (one long helix), double (one or two asymmetrical helixes in each length), and three (two short and one long and symmetrical arrangement) can be used according to the size of the equipment; in theory, the more stirring helixes. , the better the mixing effect; the equipment generally adopts a plum-shaped "displacement valve", which fits closely with the bottom of the long screw, effectively reducing the dead angle of mixing, and the driving form can be manual or pneumatic; Ball valve, star discharger, side discharge, etc.
