Laboratory mixer and extruder

The MX0.4 mixer and VTE1 extruder are some of the smallest catalyst shaping machines available on the market and are especially convenient for laboratories and researchers. They allow for catalysts to be tested as extrudates instead of powders. This results in more reliable and accurate catalytic tests, especially for lab-made catalysts. Indeed, the fact that industrial catalysts generally exist as extrudates and not powders means it is vital to conduct tests on extrudates as well as powders. 

Two steps must be executed in order to obtain extrudates from oxide gels or powders: mixing (thoroughly mixing oxides, water, and binders together) and extrusion, whether continuous (for large product volumes) or in batches (for small volumes as those achieved in R&D labs).

The MX 0.4 is a unique lab-scale mixer designed for mixing high viscosity products. It is used for catalyst extrude preparation to achieve suitable rheological properties before extrusion. 
The VTE1 is a lab-scale extruder designed for shaping catalysts into extrudates. It is particularly well adapted to the extrusion of oxides and clay pastes after thorough mixing.

Both are well adapted to the mixing or extrusion of small quantities of oxides and clay pastes such as zeolite powders with binder and water; titanium dioxide with water; alumina gel or alumina powder with water and silica-alumina powder with water. 

Some benefits of  using this equipment includes the flexibility for mixing products of different rheologies and a high resistance to corrosion. Finally, the equipment is compact and easy to clean and maintain.
