Pelletizing Extrusion Machinery

Pelletizing Precision and Consistency

Davis-Standard helps customers achieve high quality pellets through field-tested experience in underwater pelletizing, water ring pelletizing and air ring pelletizing processes. Our modular extrusion and pelletizing solutions are ideal for conventional, micro and macro pellet production.

Our engineers address key factors in pelletizing equipment design to ensure consistent melt temperature, melt flow index and melt pressure throughout the pelletizing process. We also offer more model sizes and multiple options for screen changers, heating systems, dryers, and water systems to ensure greater efficiency, value and quality.

Extrusion Feed Devices

Modular Davis-Standard pelletizing systems can be designed to receive solid or molten feed material for all polymer types and processes. Selecting the best and proper extrusion equipment technology to meet your virgin resin production, compounding, scrap reclaim or other processing needs is an important factor for profitability. Our systems come in a full range of model sizes and equipment types, giving you the freedom to build your pelletizing line around the components needed for your requirements.

All subsystem and support equipment such as screen changers, diverter valves, heating systems, classifiers, dryers, water systems, control panels can be included to provide a total system concept. Product can be fed from a reactor, holding vessel, single or twin screw extruder, continuous mixer, mill, gear pump or other feed devices. Additives can be incorporated and mixed with the main product through a feed port, injection pump, or satellite side arm extruder. Degassing of volatiles or product filtration may be included where required. The product is then discharged to the downstream pelletizing equipment on a continuous basis. The end result is superior quality, highly reliable machine lines that turn pellets into bigger profits for you.

Underwater Pelletizing Systems

Davis-Standard’s universal underwater system – the Pelletor® - offers everything you need to produce high-quality, uniform pellets. We offer several options to conventional, micro or macro pellet production using unique designs. These designs assure perfect knife-to-die plate alignment regardless of thermal or mechanical variation of the feed equipment. Very broad product viscosity ranges may be easily achieved.

The Pelletor works in either underwater, water or air ring cutting methods or both. Solution oriented options and features allow ease of operation, highest processing performance, and highest product quality. Since we offer a full range of model sizes, you have the freedom to build your pelletizing line around the system components that meet your exact criteria. All subsystem and support equipment such as screen changers, diverter valves, heating systems, classifiers, dryers, water systems and control panels may be included to provide a total system concept. The end result is superior quality and highly reliable machine lines that turn pellets into bigger profits for you.
