CrustBuster/Speed King was the first to bring you the tapered screw blender. Now, we offer it with a staggering array of options and features! Our Vertical Screw Blender is made from 304 grade stainless steel, and is available in a wide variety of sizes, from 5 tons all the way up to a super 10. It's fast too, featuring a 60 Tons Per Hour (TPH) ingest rate, and only a 10-15 second per-ton blend time once the material is added.
