Patent number: 11649595Abstract: An inner drum for use in a dryer/mixer in connection with the production of an aggregate-binder mix includes a plurality of mixing paddles disposed on the outer surface of the inner drum and arranged in a plurality of rows. The mixing paddles are configured to rotate through a mixing chamber as the inner drum rotates within an outer drum of the dryer/mixer to mix aggregate and binder together. Interstitial spaces are formed between rows of mixing paddles and material leads, where aggregate material preferentially travels as the inner drum is rotated, extend along the mixing chamber. At least one interstitial mixing paddle is located on the outer surface of the inner drum and in one of the interstitial spaces at one of the material leads. The interstitial mixing paddle rotates through the mixing chamber as the inner drum rotates to also mix the aggregate and binder together.Type: GrantFiled: April 1, 2022Date of Patent: May 16, 2023Assignee: Astec, Inc.Inventors: Kevin Risley, Chase Walker, Michael C Varner, Andrew Hobbs, Greg Renegar

Patent number: 11484832Abstract: A carbon reduction assembly adapted for use with wet and dry coal combustion products (“CCPs”). The assembly includes a direct-fired carbon reduction section having a dry material inlet device that is adapted to receive the dry CCPs and a direct-fired carbon reduction section burner unit that is adapted to reduce carbon content in the dry CCPs. The assembly also includes a direct-fired dryer section that is operatively connected with the direct-fired carbon reduction section and has a wet material inlet device that is adapted to receive the wet CCPs and a direct-fired dryer section drum that is adapted to dry the wet CCPs. The assembly further includes a control unit that is operatively connected with the carbon reduction section and the dryer section. An amount of hot gas generated by the carbon reduction section is conveyed to the dryer section, and the assembly is adapted to produce dry fly ash.Type: GrantFiled: January 7, 2022Date of Patent: November 1, 2022Assignees: Astee, Inc., Municipal Enterprises Ltd.Inventors: Wendell Feltman, Kevin Risley, Patrick Rooney, Jerry Scott, Devin Frank Whitehead, Malcolm Leland Swanson
