Conical Screw Mixer
Intro:
This mixer is broadly applied for the solid-solid (powder to powder) and solid-liquid (powder to liquid) and liquid-liquid (liquid to liquid) mixings in food, pharmacy, chemical industry, fertilizer, oil field, oil refining, animal remedy, coating, pigment, dyestuff and assistant, metallurgy, smelting, fireproof material, mine, building material, battery, electronic plastic,fodder, cultivation, biological project, health product, ceramic, glass, new material, nuclear material etc. trades. This mixer is greatly suited with mixed materials, will produce no lamination and maceration phenomenon to the mixing combined with thermo-sensitive materials and holds a good suitability to the mixing of rough materials, fine grains and extra-fine powders etc. various grains, fibers or lamellate materials.
Working principle:
The quick autorotation and revolution of the two non-30.jpgsymmetric spires of the mixer makes the material lifted upward to form two non-symmetric spiral material streams from the lower to the upper along with the bucket wall (see Fig. A and B). The revolution movement of the spire driven by the rotating arm makes the material outside of the spire enter the stud envelope line in various degrees, some is mal-positioned lifted and some is thrown out of the stud so as to get the material on the full circumferential orientation continuously renewed and dispersed, the two material streams lifted to the upper are gathered towards the central countersink to form one downward material stream, supplementing the cavity on the bottom so as to form a contra-flow cycle (See Fig. A, B, C, D, ). Because of the compound of the above movements, the materials get quick evenly mixed and hold a higher mixing degree (see Fig. E, F).
Product introduction
1.Flexible material selection
Material can be carbon steel, manganese steel, ss304, 316L and 321; different material can also be used in parts, between the part contact with the raw material and the parts don’t contact with the raw material. Surface treatment for stainless steel can be sandblasting, wiredrawing, polishing, mirror polishing
2.Reliable driven unit
The driven unit and power is varied according to different raw material, starting method, and processing.
Double screw conical mixer is equipped with appropriative double output reducer, which combines pinwheel, gear and warm and gear.
3.Excellent discharging unit
Spherical valve or plum-blossom dislocation valve is matched to the double screw conical mixer.The surface of the valve match the track of the bottom of screw, to reduce the mixing dead zone to the maximum, and to make the largest discharging area, so as to make sure no leftover. Spherical valve has excellent sealing effect to powder, liquid and even in the negative pressure state.Plum-blossom dislocation valve is easy to operate and control the discharging speed
4.Powerful auxiliary components
Equipped with circulation medium of jacket, the double screw conical mixer can realize the temperature control in mixing process.
In the mixer barrel, the part contact with material can coat some antiriot, anti-caking and metal isolation material according to different ingredient. In some severe wear conditions, the screw surface can be overlaid by some wear proof alloy.
If a small quantity of liquid is required during mixing, spraying or atomizing unit is necessary in order to mix the liquid evenly with the main ingredient. The liquid-adding system is basically composed by the three parts: pressure source, liquid storage pot and spraying nozzles.

A、Mixing Effect
The standard double screws cone-shape mixer is equipped with two agitating augers, yet single(a long auger), double(two dissymmetrical augers with different length) or triple(three symmetrical screws with two long and one short) augers is adopted in fact according to the size of the device; theoretically, more angle augers there are, better the mixing effect is.
B、Cooling and heating
Cool or heat the materials through feeding the cold or hot medium into the jacket which is added to the outside of the cylinder of the mixer. Pump industrial water for cooling and steam or heat oil heated by electricity for heating.
C、Liquid-adding mixing
The mix of injecting liquid can be achieved by connecting the atomized spray nozzle with spray pipe which is inserted in the intermediate axle location of the mixer. With choosing the specific materials, the mix of powder and liquid can be conducted by injecting acid or alkali liquid.
D、Compression Resistance
The cover of the cylinder can be made as the shape of a dome, deceasing residue to clean easily while improving compressive strength of the mixer cylinder, which should be frequently used when pressure resistance cylinder is needed.
E、Negative Pressure Feeding
The cylinder of the mixer can be made as negative pressure chamber in specific process, which breathes the dry material with good fluidity in mixing chamber for mixing using soft pipe, without residue and pollution in the feeding segment.
F、Discharging Mode
The standard device typically uses plum flower-shaped “dislocation valve” that joints closely with the bottom of long screw to decrease mix dead angle effectively with two driving methods, manual and pneumatic. It can also use butterfly valve, ball valve, star-shape material discharging device, side discharge and so on according to the user’s requirements.
