Formulation development with Caleva
The process of spheronization consists of four key steps:-
- To optimize and achieve the right binder addition & mixing time for your formulation
- Mixing or granulation - a mixer or granulator is required
- Extrusion - an extruder is required
- Spheronization - a spheronizer is required
- Drying and possibly coating - a coater and drier may be required
This is all made simple by the Caleva suite of R&D...
Does the Caleva Mixer/Granulator/Blender allow me to mix and test small batches of product?
We are frequently asked for information about the ability of the small mixer/granulator/blender, a must have tool for any laboratory needing to complete these processes quickly with small sample sizes. Recent trials provide new information about the capability of the Caleva mixer/granulator/blender (MGB) and its ability to act as a stand alone mixer when mixing powder samples of different sizes...

An opportunity to shape and form catalyst materials/particles
Caleva have had some considerable success with working with the extrusion of small quantities of catalytic material using the Caleva Multi Lab. (the first steps of blending and mixing can also be completed in the same Multi Lab base machine)
Caleva Study on the Importance of Granulation
Our customer, a major pharmaceutical, biotech & nutraceutical manufacturer with an extensive portfolio of products. For reasons of confidentiality we do not name them.
One of our Production Extruder & Spheronizer Systems for manufacturing on a large-scale was used in trials by the manufacturer, but the pellets produced were not acceptable. As the product was already registered, the composition...
Production Capacity Estimates for Extrusion and Spheronization Systems
We are often asked about the production capacity of our extrusion and spheronization systems. To provide this information there needs to be an understanding of the process parameters that will be used and that have been determined at the development stage. With that information, the advice that we give can be both meaningful and useful in the planning stages.If you have proven your concept at the...
A Brief Non-Technical Guide To Spheronization (Marumerization*)
What is Spheronization?
Spheronization is the process where extrudates (the output from an extruder) are shaped into small rounded or spherical granules. In practice these usually vary in size from 0.4 to about 3.0 mm. The use of these spheroids can be relevant for a wide variety of industries.
Why Consider Spheronization?
The products produced from this process can be useful in several ways:
Shaped Catalyst Body Preparation with MTR and Caleva Screw Extruder
Shaped Catalyst Body Preparation. Zeolite HZSM-5 (ACS Materials, M38) was mixed as a dry powder with alumina (Sasol, Catapal D (Boehmite)) and the required amount of Milli-Q water to ensure an optimum solid-to-liquid ratio for extrusion (measured using a Mixer Torque Rheometer, Caleva). The paste, containing a ratio of 70:30 wt % zeolite:binder, was extruded using a Mini-Screw Extruder (Caleva),...
Caleva explain the basic Mixer Torque Rheometer concepts - Video
The MTR can process from 10g to 25 g of your material, depending on the formulation, meaning barely any material is wasted in experiments. The machine will very quickly tell you the ideal amount of liquid to add. The user may have a start point in mind but this may result in a formulation that is too wet or too dry. The iterations may be repeated, but this can be wasteful in terms of materials...
