Mineral powder double spiral conical mixer
working principle
Mineral powder double spiral conical mixerThe two asymmetric spirals in the cylinder rotate to lift the material upward, and the rotating arm revolves slowly; the material outside the spiral enters the stud to varying degrees, thereby achieving continuous renewal and diffusion of the material in the entire circumferential direction. The two strands of material that are lifted to the upper part merge into the central recess to form a downward material flow, supplementing the gap at the bottom, thus forming a triple mixing effect of convective circulation; The standard conical screw mixer has two mixing screws. In practical applications, single (one long screw) and double can be used according to the size of the equipment.(One or two asymmetrical spirals each long and short), and three (two short and one long symmetrically arranged) spirals; theoretically, the more stirring spirals, the better the mixing effect; the equipment generally adopts a quincum-shaped "misaligned valve", which is closely attached to the bottom of the long spirals, effectively reducing mixing dead angles. The driving forms are available in manual and pneumatic options; according to user needs, butterfly valves, ball valves, star dischargers, edge discharges, etc. can also be installed.
useful properties
1) Suitable for materials with large powder particles and large proportions;
2) It is suitable for gentle mixing process of ceramic glaze and will not press feed or break the material particles;
3) There will be no overheating of heat-sensitive materials;
4) During the powder-powder mixing process, it is very convenient to add liquids required by working conditions or set up one or more spray port devices;
5) The bottom dislocation valve is convenient to discharge. Since there is no fixing device at the bottom of the screw, pressure feeding will not occur.
application
The double spiral conical mixer is suitable for a wide range of materials, mainly including powdery, granular, fibrous materials, as well as materials of different particle sizes, such as coarse grains, fine grains, ultra-fine powders, etc.

advantages
Compared with single screw mixers, it has the following advantages:
1) The mixing time is short, the efficiency is high, and the efficiency can be increased by 2 to 3 times.
2) The mixing capacity is large, and the charging factor is 20 - 30% higher than that of the drum type and 25 - 40% higher than that of the V-type mixer.
3) High mixing accuracy and low energy consumption, which can be reduced by about half (in terms of unit weight of material).
4) The height of the mixer shell is low.
5) The bottom discharge is quick, the discharge is clean and efficient, and the bottom can be tightly closed without leakage.
6) The mixing dead angle of materials can be reduced to a minimum.
7) The equipment is easy to clean and easy to replace mixed materials.
8) Avoid repairing equipment bottom bearings.
9) It is conducive to the development of equipment in the direction of large-scale.
