Description
Ribbon mixer - Low viscocity dry powders and pasty mixtures
Ribbon or belt mixing technology allows high-quality mixing at low speed. The materials are preserved and the risk of overheating is reduced. The resulting low attrition allows to maintain the initial characteristics of powders or granules blended, such as density, particle size or shape. The mixing principle is based on cross and repeated exchanges in the longitudinal direction established by the helical belt of the rotor. The slow movement of rotation is particularly suitable for heat-sensitive, fragile and abrasive materials.
Discontinuous belt mixers consist of a rotor shaft with opposite coils, located in a mixing tank.
Batch belt and ribbon mixer are available in 2 versions:
- Loading through hopper: MRRA
- Loading through cuff: MRRC
Operating mode |
Constitution of the belt and ribbon mixer:
- A central filling opening or alongside the tank
- A central outlet opening
- A vent mouth
- Two closing plates for the ends of the tank to support the end bearings (adjustable and equipped with a shaft sealing unit)
- A gearbox with transmission
Equipment advantages
- Homogeneity of the mixture
- Excellent batch reproducibility
- Gentle treatment of the material without damaging it
- Possibility of complete discharge
- 100% loading rate possible
