摘要
The purposes of powder agglomeration are the production of dust-free granules or specific properties by granulation. Good experience in the extrusion compression of powders containing moisture or binding agents has been obtained in the last few years with co-rotating self-cleaning twin-screw extruders. Based on the building block principle of the screw barrels and screw geometry, the machines can be easily adapted to the various products such as catalyst carriers, carbon powders, additives, and other chemical products.
