Double spiral mixer is widely used in the mixing of powders and powders (solid-liquid) of chemicals, pesticides, dyes, food, feed, building materials and rare earths. The machine has wide adaptability to the mixture material, does not overheat the heat sensitive material, does not pressurize and grind the granular material, and does not produce chip separation phenomenon when the material with different specific gravity and particle size is mixed; the machine according to the process requirements The jacket can be added outside the mixing barrel, and the cooling or heating of the material can be realized by injecting a cold heat medium into the jacket; the cooling is generally pumped into industrial water, and the heating can be steamed or electrically heated.
The working principle of the double helix mixer: two asymmetric spiral rotations in the DSH series mixing cylinder lift the material upwards and the arm rotates slowly; the materials outside the spiral enter the studs to different degrees, thereby achieving the full circumferential orientation of the material. Constantly updating the diffusion, it is mentioned that the upper two materials merge to the central cavity to form a downward flow, which complements the bottom vacancy, thereby forming a triple mixing effect of the convection cycle; the standard cone spiral mixer There are two stirring spirals. In practical applications, depending on the size of the equipment, single (one long spiral), double (one or two asymmetric spirals) and three (two short and one long symmetrically arranged) root spirals can be used; theoretically stirring The more the spiral, the better the mixing effect; the equipment generally adopts a plum-shaped “displacement valveâ€, which is closely attached to the bottom of the long spiral to effectively reduce the dead angle of the mixture. The driving form is manual and pneumatic; the user can also add according to the needs of the user. Features of butterfly screw, ball valve, star unloader, edge discharge and other double screw mixers:
1. The cone cylinder adapts to the high requirement of no residue in the mixture.
2, the gentle stirring speed will not cause damage to the fragile materials.
