Types of Extruder Granulator Machines

Extruder granulator machines are classified based on their design and operation:

• Single-Screw Extruders: Utilize a single screw to convey and compress the molten material, creating a uniform melt.
• Twin-Screw Extruders: Employ two intermeshing screws for more efficient mixing, shearing, and conveying, resulting in better granule quality.
• Underwater Pellet Cutters: Submerge the extruder die in a water bath, where molten strands are rapidly cooled and cut into granules.
• Strand Cutters: Cut molten strands into granules after they extrude from the die and before cooling, offering higher throughput and smaller granule sizes.

Features of Extruder Granulator Machines

Extruder granulator machines come with a range of features to meet specific application requirements:

• Throughput: Determines the volume of material processed per unit time, measured in kilograms per hour (kg/h).
• Granule Size: Controls the size and distribution of granules, ranging from coarse to fine.
• Die Design: The shape and configuration of the die influence the shape and consistency of granules.
• Materials of Construction: Machines are typically made from durable materials such as stainless steel to withstand high temperatures and corrosive environments.
