AccuRate/Schenck AccuRate Datasheets for Feed Screws and Mixer Screws

Feed Screws and mixing Screws are screws or augers placed in bins, silos, extruders, hoppers, or molding machine to provide uniform flow. As the screw turns, process material is mixed and conveyed.

Product Name Notes
A standard helix used for most applications. The helix pitch equals the diameter of the helix.
Excellent for adhesive/cohesive materials like TiO2 and Calcium Carbonate. The reduction of material build up and pulsing is also realized with a twin screw system.
For materials that cannot come into contact with metal or for applications that do not allow metal-to-metal contact.
Helix has two discharge flights and is used in batching applications to reduce the deviation caused when the flight stops and a small amount of material drops off the end.
Polished, machined, stainless steel bar stock that is typically used for food and pharmaceutical applications.
The center rod is used for added strength in smaller diameter helixes and to reduce possible flooding. Cannot be used with adhesive/cohesive materials.
The increased spacing between the flights promotes filling of the flights on very cohesive materials. The helix pitch is two times the size of the helix diameter.
Used when you need the larger diameter flights to get cohesive materials to drop into the flights, but has reduced output compared to a full pitch open flight helix. The...
Used with a tight fit poly nozzle adapter for adhesive/cohesive materials such as TiO2, Zinc Oxide, and Iron Oxide. The helix continuously cleans the nozzle walls to prevent material build...
Used with an over size nozzle with end bushing on pellets, beads, and irregular materials. Provides a clearance between the helix and nozzle adapter to prevent binding.
