Twin Shaft Mixer
An introduction to the twin shaft mixer:
A twin-shaft mixer is a type of mixing equipment that is widely used in the chemical industry, food industry, pharmaceutical industry and other fields. It humidifies and stirs the material while conveying it by using a pair of screw shafts with stirring blades rotating synchronously in the opposite direction.
The working principle of the twin-shaft mixer is to force the turning and stirring of the material to be mixed by means of two axial movements perpendicular to each other so as to achieve the purpose of mixing. It usually consists of a mixer cylinder, mixer blades, motor and transmission device.
This type of mixer has high mixing efficiency, compact structure, stable operation, clean and environmentally friendly. It is suitable for various production lines

Assembling structure of double shaft mixer:
The double-shaft agitator mainly consists of a casing, a screw shaft, a drive, a coverplate, a chain cover, etc., with the following specific structure and performance features:
1) The shell is mainly composed of plates and profiles, which are welded and formed in the manufacturing plant and assembled with other parts, and is the supporting structure of the double-shaft mixer.
2) The spiral shaft assembly is the main component of the double shaft mixer, and its components mainly include the left and right rotating spiral shafts, the bearing seat, the bearing bush, the bearing cover, the gear, the blade and other parts.
Principle of operation of twin-shaft mixers:
- The material to be mixed is fed into the mixing vessel through the inlet opening.
- Two mixing shafts are driven by the motor. They rotate in opposite directions. The shafts are fitted with helically arranged mixing blades to ensure efficient mixing of the materials.
- The mixing paddles attached to the rotating shafts ensure thorough mixing of the products as they rotate.
- In the overlapping area of the twin shafts, materials with different rotational directions are displaced and interact. This increases the overall mixing efficiency. This dynamic interaction ensures complete mixing of the materials. This contributes to the superior performance of the twin shaft mixer.
This range of twin shaft mixers has the following characteristics
1) Practical design: the shell is tightly sealed, so there will be no ash flying out and leaking. The spiral shafts rotating to the left and right require a high degree of manufacturing precision and have a good process performance.
2) Good mixing effect: Adopting double shaft design, mixing blades rotate and flip simultaneously, which can fully mix and stir materials, making mixing effect more uniform.
3) High production efficiency: The double-shaft mixer is able to turn and tilt simultaneously during the mixing process, increasing the mixing speed of the material and improving the production efficiency.
4）Long service life: the gears have protection guards, so the operation can be safe and effective. After wear and tear, the blade structure is reasonably designed and simple, easy to replace.
5) Stable construction: The double-shaft mixer adopts a stable and durable construction that has high stability and safety.
In the fertilizer industry, the role of the twin-shaft mixer is the mixing of raw materials with different compositions for the preparation of high quality fertilizer products.
For the quality of the product, the homogeneity of the fertilizer ingredients is very important. The use of twin-shaft mixers effectively avoids the problem of non-uniform or lumpy composition and enhances the quality stability of fertilizer products.
