Our Terms and Conditions of Sale


For over 50 years Caleva Process Solutions have designed and manufactured high quality products that have shaped the way our clients understand extrusion and spheronization.

We work in close partnership with our customers from various backgrounds in their developments that surround the need to make pellets and extrudates using the processes of extrusion and spheronization.

If you are involved in the pharmaceutical, catalyst or ceramic industries (beads) and are thinking about extrusion and spheronization to make pellets then talk to Caleva.


Please talk to us if you would like advice about:

  • R&D development
  • Pilot plant development or full scale production with extrusion and spheronization
  • Planning to develop or manufacture pellets, extrudate or beads
  • Spheronizing any product - we want to help!

In addition to extruders and spheronizers we uniquely offer laboratory equipment such as:

  • Mixer Torque Rheometer -  to optimize formulation development
  • Mini Coater Drier - a small-scale fluid-bed laboratory tablet and spheroid coater/drier capable of coating as little as a single tablet or a few grams of spheroids (pellets), and;
  • Caleva Multi Lab - what we believe is the smallest laboratory high shear granulator available (batch size from 10 to 50g)
