Working Principle:

Mini Dome Granulator is bench-scale, single screw extruder, which is capable of extruding wetted powders into granules ranging from 0.3-2mm in diameter. The wetted powders, which is typically prepared in a kneader or hand mixing, is gravity fed into the feed hopper. The single screw transport the wetted powders to the extrusion zone where it is then wiped through a conical die (screen) to produce extrudates of a controlled diameter. The extrudates break off by their own weight and are collected for the next processing step.  

Mini Dome Granulator is specially designed for R&D in lab and small scale production. The extruded granules can be dried or spheronized, depending on the desired end result.

Technical Features:

• Low pressure extrusion with negligible heat generation due to unique design of conical die (screen) and extrusion head.
• The hole size of conical die (screen) is 0.3-2mm. And it's very easy to change the die. 
• All the extrusion parts are made by SUS304 or SUS316L stainless steel and can be easily dismantled for cleaning. 
• Special drive shaft sealing design can 100% make sure contamination free of product.
• Robust,simple and compact design requires minimum maintenance. 
• Axial flat die can be installed when the required hole size is bigger than 2mm. 

Technical Parameters:

Note: Our Dome Granulator can also work with flat die when the hole size is bigger than 2mm.
