Belt or ribbon mixer - Discontinuous

Description

Horizontal ndustrial mixer - Bulk materials and powder handling

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
The external axis conveys the material from both sides towards the center, while the inner axis conveys the material to the sides, producing a convective mixing. The product is gently mixed in a relatively short time: from 5-15 minutes depending on the complexity of mixtures and the amount of each ingredient.

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
