Description
This system is made up of:
- Caleva Variable Density Twin Screw Extruder (VD-TSE70), together with
- The industry leading Caleva Spheronizer 700
Designed for continuous or intermittent production within industrial environments. An example of reliable and efficient British engineering at its best - this is the option for your pellet production and is backed by the highly acclaimed support from Caleva Process Solutions.
The Caleva system gives you the ability to vary the density of the extrudates or pellets. This allows you to fine-tune your process to be ideal for your product properties and the intended use of your pellet or extrudate. This allows you to scale-up from your formulation development with any laboratory benchtop extruder. If you have not completed your laboratory formulation development, then you might consider the laboratory Variable Density Extruder or the Caleva Multi Lab as the VD-TSE70 is the logical next step in the scale-up pathway.
Twin Screw Variable Density Extruder
This surprisingly compact and efficient extruder has produced up to 200 kg of extrudate per hour using axial extrusion. A range of different die patterns (hole diameter and depth) and shapes (such as clover-leaf and trilobe holes - suitable for industrial materials in the petrochemical and catalyst industries) are available. Test your product with us and learn why the Caleva Variable Density Production Extruder is your most flexible option.
Caleva Spheronizer 700
Caleva spheronizers have been the industrial production standard for 50 years. Our Spheronizer 700 is the safest and most advanced currently available. You can have confidence based on Caleva's experience and focus on the provision of large-scale spheronizers that are in used in production by both large manufacturers and smaller contract manufacturers around the world.
Recommended Spares & Consumables
The product manuals fully describe our recommendations for consumables and recommended spares. All spares and consumables are designed for robust use and are covered by Caleva's warranty
Consumables are items that could easily be lost or misplaced during cleaning and turnaround procedures.
Recommended spares should be considered based on the materials used in the equipment and an appreciation of the wear rate expected. Pharmaceutical materials generally have a relatively low wear rate. Catalyst materials will have a higher wear rate. In either case the parts that wear are:
Spheronizer
Spheronizer Disc
Adaptor Shaft Seal
Extruder
Left Hand Screw Auger
Right Hand Screw Auger
Left Hand Pressing cam
Right Hand Pressing Cam
Extrusion Barrel
Dies
We recommend a regular review of a requirement for spare parts for the following reasons:
- To maintain higher outputs and reduce cleaning turnaround
- Share the wear rate - a second set ready to install at cleaning phases makes for a quick turnaround and shares the wear
- In applications where wear rate is going to be high then these parts will need to be replaced regularly - having spares line side will help avoid any downtime
