Ploughshare or blade mixer

‹‹ ››

Mixing 100% solid materials or incorporating liquids up to high viscosity

Available in two operating versions: continuous or discontinuous (batch).

Operating mode

These mixers are based on the principle of mechanical fluidisation of the product. The particular shape, position and rotation speed of the mixing tools, creates a centrifugal vortex motion, which allows the materials to be projected in a three-dimensional way and to merge with each other. This ensures that components with a different particle size and bulk density are perfectly blended and mixed with high precision within the shortest possible time.

Continuous mixers

The management of flow rate and duration of stay of the material in the tank are performed according two technologies:

1. internal diaphragm angularly set: preferred version for monoproducts processes where the setting rarely intervenes

2. slide valve with height adjustment from the exterior enabling simple and easy adjustment for batch changes

Advantages of continuous mixing:

  • Operating time / high availability
  • Minimum wear / low maintenance

Discontinuous mixers

Batch mixers for solid materials enable an excellent mixing quality in a short time. These standard mixers are widely used in the agri-food and chemical industries. The reduced size of the mixer and its high finishing minimize the retention and offer a response to all mixing processes.

  

Main avantages

  • Excellent reproducibility of batches 
  • Manufacturing in carbon steel, 304L, 316L and 316L L stainless steel
  • Dispersion: 20 gr./t.
  • Maximum mixing homogeneity

Options

Liquid spraying blowpipe

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.
dispersion choppers

Disperser

For agglomeration, granulating and coating process.
Dispersers, also known as choppers or knives, are tools that break the lumps and agglomerates and allow the production of high quality and homogeneous final product.

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).

Pressurized_balloon.jpg

Pressurized balloon for addition of liquid

A pressurized balloon allows the addition of liquid during the mixing phase
In order to ensure the introduction of fluids (oil, fat, aromas ...), we offer pressure tanks or metering pumps to ensure the spraying of the liquid at the heart of the mixture. This option must be combined with the implementation of choppers / dispersers.
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.
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.
