Double shaft mixer introduction:
A double shaft mixer is a type of Fertilizer blender. It uses the synchronous rotation of two symmetrical screw shafts to add water and stir while conveying granular or powdery materials such as fertilizers to evenly humidify the granular or powdery materials to make the powdery The material reaches a controllable humidity, which facilitates the transportation of the material or transfers to other conveying equipment. This equipment is mainly used for humidifying and mixing raw materials in the fertilizer industry. Make the material stir thoroughly. Compatible with conveying function.
Double shaft mixer structure:
1. Main motor and cycloid reducer (transmission machinery);
2. Meshing transmission gear;
3. Front and rear thrust bearing assembly;
4. Active and passive spiral stirring shaft;
7. Material inlet and outlet;
Working principle of Double shaft mixer:
When the dry powder material is quantitatively fed into the trough body through the feed port by the feeder, the power transmission machine drives the spiral main shaft equipped with multiple sets of blades to rotate and drives the driven screw shaft and the main shaft to make a constant velocity relative to the meshing transmission gear. Rotate, so that the materials are mixed and pushed to the humidification section of the tank. After the materials are pushed to the humidification section, the humidifier automatically sprays the materials, and then the mixing section after the tank is fully agitated. When the materials reach controllable After humidity, it is discharged from the discharge port and enters the next process.
Structural features of Double shaft mixer:
1. The shell is tightly sealed, and there is no fly ash or ash leakage.
2. Components mainly include left and right screw shafts, bearing seats, shaft sleeves, bearing caps, gears, sprockets, oil cups, blades, and other components. The left and right screw shafts require high manufacturing precision and good process performance. They have strict requirements on the matching of bearing seats, shaft sleeves, and bearing caps. There are 8 gear modules, the number of teeth is 60, the tooth profile angle is 20°; the sprocket pitch is 50.8, the number of teeth is 25, and the tooth profile is GB1224-85. The gears and sprockets are protected by a protective cover, which makes the operation most effective. The oil cap is a kind of pressure oil cup, which is convenient and effective to add lubricating oil. The blade material of the double-shaft mixer adopts composite ceramic material, which is wear-resistant and not easy to stick to dust. The blade structure design is reasonable and simple, easy to replace after wear, long service life.
3. The water and humidification pipeline is mainly composed of pipes, joints, and nozzles.
Performance characteristics of Double shaft mixer:
The double shaft mixer has high mixing efficiency and a small footprint. The agitator is driven by a reducer, which rotates smoothly and has low noise. The structure is reasonable, with top in and bottom out. The joint surfaces are tightly sealed, and the operation is stable.
