FAQs

Are you working with thick, viscous or sticky granulations?

Scenario/Solution

We are currently working with many of our clients to ease this process. To find out how, contact us now to discuss our new High Viscosity mixing blades.  Our new High Viscosity Mixing Blades, designed for making those sticky, viscous, difficult, granulations much simpler.

High Viscosity mixing blades
 

Our design team have been working tirelessly to come up with a solution to a constantly asked question.

"Is there a better way to granulate with our viscous materials?"

Our clients have been experiencing, stuck blades, inhomogeneous granulations and extremely long mixing times, until now. The HVM blades have been designed in conjunction with our customers and now after extensive testing are available for our Caleva Muti Lab. The two rotating blades at a 1:2 ratio creates mixing pockets to make those difficult materials into successful homogeneous granulations...read more

Challenge

"Aaron, as you know we are extruding hard ceramic powders using small organic molecules as binders. One of the challenges we still have is that the temperature due to the high localized pressure decomposes the organic molecule. We think that that's why our extrudates change color. We would be very interested to hear about any improvements on that. Other than that we are really satisfied with the equipment." Alejandro López Research Engineer/Materials Developer at Uppsala University
 

Caleva Insights & Solution

"Alejandro, it's really great to hear from you. I hear your challenges, I too have come across similar issues due to temperature gain during extrusion. I have found however that by cooling the raw materials before extrusion really helps to maintain their properties. Would cooling your organic molecules be an option for you? Alternatively, our larger extruders are supplied with cooling jackets to combat this issue too. I hope this helps." Aaron Quinn International Sales Manager at Caleva
