Ribbon mixer

‹‹ ››

Pour les pulvérulents secs et mélanges pâteux à basse viscosité

Main characteristics of  the mixer

The ribbon batch mixers consist of a rotor shaft with opposite axis, mounted in a mixing tank.

Main advantages

  • Homogeneity of the mixture
  • Excellent batch reproducibility
  • Gentle handling of the materials without any damage 
  • Possibility of complete discharge
  • Possible loading rate of the mixer at 100%
     
 

Operating mode

The external axis conveys the material from both sides towards the center, while the inner axis transfers 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 amounts of each ingredient. Usually, ribbon mixers are used for PVC dry blends production, dry powdery materials and low viscocity pasty mixtures.

Options

Liquid_injection_device.jpg

Liquid injection device

For the addition of additive in the mix.
The liquid spray device is located at the level of the ploughshares and the dispersers and thus enables the controlled addition of liquids in small quantities in the preparation. The chopper, positioned beneath the device, creates a vortex for better dispersion of the liquid.

Pneumatic_sampling_device.JPG

Pneumatic sampling device

Validation of the quality of the batch.
The sampler collects a small amount of the mixture to verify its quality.
Temperature_sensor.jpg

Temperature sensor

Set on the mixing tank
The temperature sensors transmit reliable temperature measurements for applications dealing with sensitive products (eg for sanitary / cosmetic / pharmaceutical applications).

Integral_discharge_hatch.jpg

Integral discharge hatch

For a full discharge of the mixer
The integral discharge hatch allows to limit cross-contamination by reducing the maximum retention of product in the mixer.
Opening size: 15 ° or 60 °
Double_casing.PNG

Double casing - heating / cooling

To adjust the temperature of the mix inside the mixer
The double casing of the mixer allows heating its contents through the circulation of the coolant fluid in the doule casing, or cooling by circulation of chilled water.
Blowing_box.JPG

Air or nitrogen blowing box

For the management of air or nitrogen blowing
The pneumatic control box has a function of controlling the flow and air or nitrogen pressure for the sealing of the bearings.
