• The extrusion rate can be from 5g samples to commercial extruders capable of extruding 500 kg or more per hour.
  
   
• Caleva will design with you and build specifically for your needs.
  
  
• The choice between gear, screen and screw extruders for development should be made with care as it can influence equipment cost well into the life cycle of a product.
  
  
• Contact us for guidance as the choice depends on the formulation characteristics and the density of the extrudate required. 
  
   
• The right equipment for you would depend on the specific needs of your application.

• Extrusion is an integral part of the extrusion and spheronisation process.
  
  
• A wet mass formed in granulation step is forced through dyes and shaped into small cylindrical particles having a uniform diameter.
  
  
• The extrudate formed must have enough plasticity to deform but not be so sticky as to adhere to other particles when placed into the spheroniser.
