What is the working principle of a double shaft mixer

The working principle of a dual axis mixer is mainly based on the synchronous rotation of two symmetrical spiral shafts. This mechanism works together in multiple ways to achieve uniform mixing and humidification of materials. The following is a detailed analysis of its working principle:

Basic working mechanism

• Spiral shaft rotation: When the dual axis mixer is started, the two symmetrical spiral shafts begin to rotate synchronously. These two shafts not only serve to transport materials, but also promote material mixing through their rotational motion.
• The function of stirring blades: The design of stirring blades is crucial, as they can effectively push materials in different directions and form a flow state. With the rotational motion of the dual axis and stirring blades, the material is rapidly stirred, cut, thrown, and mixed.

Humidification process

• Mixing with water: While conveying powdered materials such as dry ash, the double shaft mixer also humidifies the materials through a water addition device. Water is supplied by a spray device consisting of water pipes and nozzles. The nozzles are arranged axially along the spiral axis to form a water curtain, which is conducive to the humidification and mixing of materials.
• Uniform humidification: Through the rotation of the spiral shaft and the flipping of the stirring blades, the material and water come into full contact and mix, achieving the effect of uniform humidification. This process ensures that the humidified material neither emits dry ash nor seeps out water droplets, making it easy for subsequent loading and transportation or transfer to other conveying equipment.

• Convection mixing principle: The dual axis mixer also utilizes the upward throwing motion of the material inside the mixer to form a convection layer, generating instantaneous weight loss and achieving the optimal mixing state of the material. This principle helps the material to form a continuous circulation and flipping in all directions within the machine slot, intersecting and shearing with each other, thereby achieving a fast, soft, and uniform mixing effect.
• Efficient mixing: Due to the low operating speed and high mixing efficiency of the dual axis mixer, the material moves smoothly during the mixing process, reducing material wear and breakage and ensuring mixing quality.

Structural characteristics

• Main components: The dual axis mixer is mainly composed of a casing, a screw shaft assembly, a drive device, piping, a cover plate, a chain cover, and other components. The casing is tightly sealed to prevent fly ash from flying out and leaking; The spiral shaft assembly has high precision and good process performance; The mixing blade material is wear-resistant and not easy to stick to dust.
• Design advantage: The blade structure of the dual axis mixer is designed reasonably and simply, and is easy to replace after wear and tear; The nozzle is made of stainless steel material, which is corrosion-resistant, durable, and easy to replace; There are inspection holes on both sides for easy daily maintenance and upkeep.
