Introduction

A Double Screw Extrusion Granulator is a vital piece of equipment in the manufacturing and chemical industries. It is used for producing granules from powder materials by mixing, compressing, and heating, employing a pair of co-rotating screws. These granulators are integral in ensuring high productivity and efficient processing for various applications.

Working Principle of Double Screw Extrusion Granulator

The double screw extrusion process involves two intermeshing screws that rotate inside a closed barrel. Material is fed into the system and transported through the barrel where it undergoes a sequence of mechanical processes including mixing, shearing, and heating. The end product is extruded through a die, resulting in consistent granules with a uniform shape and size.

Advantages of Double Screw Extrusion Granulators

• High efficiency in processing due to effective heat and mass transfer.
• Consistent product quality with uniform size and shape.
• Versatility in handling a wide range of materials.
• Enhanced mixing capacity compared to single screw extruders.

Applications

Double Screw Extrusion Granulators are employed in diverse industries including pharmaceuticals, agriculture, and food processing. They are particularly valuable in the production of fertilizers, where precise formulation and granulation are crucial for product performance.
