The Caleva Gear Extruder high density Extrusion and Spheronization kit is a small scale production kit with an output between about 40 to 60 kg per hour linked with a Caleva Spheronizer 500.
The Caleva Gear Extruder 40 is a cost effective gear extruder ideal for many pharmaceutical and other industrial applications where a dense, high quality, extrudate is required.
Gear extruders have significant and real advantages when high density extrudate is required and especially with products that can be sensitive to heat.
The principle of operation is different to other extruders. The product is allowed to fall between two rotating gears. The base of the gear tooth has holes so that the product is pushed through the base of each gear into the hollow centre and falls out of the front of the gear.
This process is the type of extrusion that generates the least possible amount of heat during the extrusion process.
If you need a high density Extrudate and your product is sensitive to heat then talk to us and discover if a gear extruder is the right choice for you.
