Ribbon Mixer Overview and Applications

Ribbon mixer consists of a U-shaped container, ribbon stirring blades, and transmission components. The long, U-shaped cylindrical structure ensures low-resistance movement of the mixed materials (powders, semi-fluids) within the cylinder. The forward and reverse rotating ribbons are mounted on the same horizontal axis, creating a low-power, high-efficiency mixing environment. The ribbon blades are typically double or triple-layered; the outer spiral gathers the material from both sides to the center, while the inner spiral conveys the material from the center to both sides, creating more vortices in the flow. This accelerates the mixing speed and improves mixing uniformity.

Ribbon mixer discharge methods: Powder materials use a pneumatic large-opening gate structure, offering advantages such as fast discharge and no residue; high-fineness materials or semi-fluid materials use a manual or pneumatic butterfly valve. Heating or cooling jackets can be configured. Heating methods include electric heating and thermal oil heating. For cooling, cooling water can be directly injected into the jacket; the jacket has a large heat exchange area and a fast cooling speed. Small-sized mixers use a direct-drive reducer, resulting in a simple structure, high operational reliability, and convenient maintenance. Large-sized mixers use a belt pulley-driven cycloidal reducer; the elastic connection of the belt drive offers the advantage of protecting transmission components in case of overload.

Ribbon mixer applications: Used in food, chemicals, biological products, aquaculture, ceramics, refractory materials, plastics, compound fertilizers, etc., for mixing solid-solid (powder with powder) and solid-slurry (powder with slurry) materials. It is particularly suitable for mixing viscous materials.

Ribbon mixer operation procedure: Before use, a no-load test run should be performed. Before the test run, check the tightness of all connections, the amount of lubricating oil in the reducer, and the integrity of the motor. Then, close the main power switch for the no-load test run. The material should be loaded enough to submerge the slurry shaft. After adding material, the trough cover must be closed before starting the machine to prevent material from overflowing. The cover is equipped with a sight glass basket to observe the mixing process.
