Feed premix double helix cone mixer

Feed premix double helix cone mixer

working principle

Feed premix double helix cone mixerTwo asymmetric spirals inside the cylinder rotate to lift the material upwards, and the rotating arm moves slowly around the revolution; The material outside the spiral enters the screw column to varying degrees, achieving continuous updating and diffusion of the material in all circumferential directions. The two streams of material lifted to the upper part then converge towards the central cavity, forming a downward material flow that fills the gap at the bottom, thus creating a triple mixing effect of convective circulation; The standard conical spiral mixer has two stirring spirals. In practical applications, single (one long spiral), double (one asymmetric spiral for each length), and three (two short and one long symmetrically arranged) spirals can be used according to the equipment specifications; In theory, the more stirring spirals there are, the better the mixing effect; The equipment generally adopts a plum blossom shaped "displacement valve", which is tightly attached to the bottom of the long spiral, effectively reducing mixing dead corners. The driving form is available in manual and pneumatic modes. According to user needs, butterfly valves, ball valves, star shaped unloaders, edge discharges, etc. can also be installed.

Applicable characteristics

1) Suitable for materials with significant differences in specific gravity and large powder particles;

2) Suitable for mild mixing process of ceramic glaze materials, without pressure feeding or crushing of material particles;

3) Will not cause overheating of thermosensitive materials;

4) In the powder powder mixing process, it is very convenient to add the liquid required by the working conditions or set one or more spray port devices;

5) The bottom displacement valve is convenient for discharging, and since there is no fixed device at the bottom of the spiral, there will be no pressure feeding phenomenon.

application

The double helix cone mixer is suitable for a wide range of material types, mainly including powdered, granular, fibrous materials, as well as materials of different particle sizes, such as coarse particles, fine particles, ultrafine powders, etc. ‌

Powdery and granular materials: suitable for mixing various powders and granular materials, such as pharmaceuticals, food, chemicals, pesticides, feed, petroleum, metallurgy and mining, building materials industry, etc.

Fibrous material: suitable for mixing fibrous materials, able to maintain the original particle size and shape of the material.

Materials of different particle sizes: Whether it is coarse particles, fine particles, ultrafine powders, or other materials of different particle sizes, they can be well mixed in a double helix cone mixer without causing layering or segregation.

Applicable Industries

Pharmaceutical industry: used for mixing various granular, powdered or liquid materials, suitable for the mixing of various powders and powders, liquids and liquids, and powders and liquids in the pharmaceutical process.

Food industry: suitable for mixing powder and granular materials in food processing, such as additives, refractory materials, electronic plastics, etc.

Chemical industry: suitable for mixing chemical raw materials, battery raw materials, coatings, dyes, pesticides and other materials.

Other industries: also suitable for powder mixing in industries such as feed, petroleum, metallurgy and mining, and building materials.

advantage

Compared with a single screw mixer, it has the following advantages:

1) Short mixing time, high efficiency, can increase efficiency by 2-3 times.

2) The mixing capacity is large, and the loading coefficient 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, low energy consumption, can reduce by about half (referring to the unit weight of materials).

4) The height of the mixer housing is low.

5) The bottom discharge is fast, the discharge is clean and tidy, and the bottom can be tightly closed to prevent material leakage.

6) The dead corners of material mixing can be reduced to the lowest possible level.

7) The equipment is easy to clean and facilitates the replacement of mixed material varieties.

8) Avoid repairing the bottom bearings of the equipment.

9) Beneficial for the development of equipment towards larger scale.
