This extruder is controlled by PLC, it is easy to use. It is equipped with cutting knives so that the granule length is adjustable.
DOUBLE SCREW EXTRUDER
The popularity of twin screw extruders is attributed to its versatility and applicability to a remarkably wide range of materials. Besides this, extruders allow continuous processing and are capable of delivering high value, high quality products in large quantities. The growing number of industrial applications of extrusion technology in the last few decades has led to an increasing interest in understanding the extrusion process. However, the complexity of the extrusion process such as the shear, mixing, flow performance and the material interaction make the study very challenging and empirical approaches have made little contribution to the fundamental understanding of the process.
JUNZHUO MACHINERY single/double screw extruder is suitable for most low pressure wet extrusion processes used in solid dosage processing. Extrusion performed by two detachable, contra rotating gears. This action generates minimum heat and does not work the product excessively. This makes it ideally suited for extruding pharmaceutical products. Feeding can be done manually or automatically by auger feed.

Working Principle
The motor power is driven from the v-belt wheel to the gear box, power is distributed through the drive parts inside the gear box, and the double screws start working. Add raw material into feeding hopper, the wet mixed powder is extruded by the left and right screws and forced through screen mesh to be columnar particles.The granule length can be adjusted by cutter.

Twin screw extruders consist of two intermeshing, co-rotating screws mounted on splined shafts in a closed barrel. Due to a wide range of screw and barrel designs, various screw profiles and process functions can be set up according to process requirements. The major advantage of intermeshing co-rotating twin screw extruders is their remarkable mixing capability which confers exceptional characteristics to extruded products and adds significant value to processing units.
In twin screw extrusion processing, the raw materials may be solids (powders, granulates, flours). Extruded products are chemically modified polymers, textured food and feed products, cellulose pulps, etc.
