Die Roller Extruder

Detailed Information on Die Roller Extruder

Umang’s Die Roller Extruder is designed for continuous extrusion processes, especially effective for wet granulation techniques. This method applies pressure to a mass, forcing it to flow through an orifice, which determines the shape and size of the particles. The shape is defined by the orifice, and the length is controlled by the cutter. The size of the die roller holes directly affects the size of the extrudates. Die roller extrusion is an established technique with two main parts: The die roller with holes of the desired size and the knurling (pressing) roller. These rollers press the wet mass to form the extrudates. Needles inside the die roller create perforations, and these are cut into lengths by the cutter. This design creates denser granules compared to other methods and is especially suited for extruding hard materials. Operation of Die-Roller Extruder The extruder operates on a plug flow ’first in, first out’ principle without stagnant areas. Product holdup at the end of a run only amounts to a few grams. Pre formulated wet mass is loaded into the circle feeder. Activate the machine. The wet mass feed is regulated into the nip area between the two rollers. The material feed is forced through the perforations of the die roller by the pressing action of the Knurling Roller (Pressing Roller) against the Die roller. The extrudes of uniform diameter comes through the perforations of the die roller inside. They are cut into length and guided, with the help of a cutter provided. The extrudes easily fall to collecting tray due to the tilted design. Overflow material comes through the bottom opening of extrusion chamber can be recycled through circle feeder.

Improved Surface Finish: The rolling action of the die rollers can produce a smoother and more consistent surface finish on the extruded product, which is especially beneficial for applications requiring high-quality surface aesthetics. 2. Increased Production Efficiency: Capable of processing large volumes of material at a high rate, suitable for mass production. 3. Reduced Material Waste: Precise control over the extrusion process minimizes material waste, leading to cost savings and more sustainable production practices. 4. Enhanced Mechanical Properties: The rolling action can enhance the mechanical properties of the extruded material, such as tensile strength and durability, by promoting better alignment of the material structure. 5. Scalability: Die roller extruders can be scaled to meet various production needs, from small-scale laboratory setups to large-scale industrial operations.
