Catalyst Extrusion Equipment

Diamond America designs extrusion equipment to handle all catalyst/ceramic carriers in the petrochemical, DeNox and water purification industries to ensure peak efficiency. From forming tiny pellets to solid or hollow rods, our custom designed extruders provide continuous production of the catalyst configuration you desire.

Catalyst Equipment Features:

  • Increased throughputs due to screw and barrel design
  • Reduced maintenance and increase wear life due to higher quality of construction
  • Positive feed achieved through improved twin-feed throat and screw design
  • Designed for modular construction to allow for easy repair and replacement
  • High capacity bearings provide increased pressure capability while gear-motors provide compact performance without concern for belt slippage or maintenance

Diamond America’s Table Top Extruders are perfect for running small batches or testing applications in a laboratory setting.

We offer Table Top Extruders in 1” and 2” models. Customized features and options — dies, feeders, cutters, etc. — are available and are designed and built per customer specification.

Twin Feed Extruders

Twin Feed Extruders
Application: Catalyst, Food, Mastics

Diamond America’s Twin Feed Extruders feature our counter-rotating feed screw design. It provides our customers with the ability to process the most challenging materials while maintaining a positive feed to the extrusion screw. Our completely original design changes the geometry of the screws, barrel liners and feeders used in the extrusion process. As a result, we are able to reduce unwanted friction and eliminate stagnation while operating at peak energy efficiency. 

Built to handle the hard stuff — Petrochemical Catalysts, DeNox Catalysts, Carbon, Rubber (EPDM and Recyclable), Silicone, Clay, and Ceramics — as well as Food Manufacturing (Confectionary, Pet Food, Pasta).

Twin Feed Extruders are available in 2”, 4” or 6” base models, and can be customized to include various die assemblies (profile or pellet processing), temperature control options, and rotary or guillotine cutters.

With proven results in several markets, from catalyst, mastics and ceramics to food, plastics and consumer products, Diamond America manufactures extrusion equipment designed to work and built to last.

Not every application, processing condition and end product is created the same. Our first step in the development a customer’s extruder is thorough research. This includes testing your materials in our lab to determine the ideal extrusion process for producing the high quality structured products our customers demand.
