Double Screw Mixer from Shenyin Mixer

Product introduction：
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-symmetric 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).

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.
