  • Foundry sand
    Patent number: 6516863
    Abstract: Apparatus and methods for preparing foundry sand mixes, using a pre-mix tank to pre-mix water and particulate bond material to make a water/bond slurry, then feeding the slurry to a mullor or other foundry sand mixer. The slurry is received in the mullor/mixer, mixed with return sand, and then discharged for use in making foundry molds. Preferably, the particulate bond material is added to the pre-mix tank as a falling stream of such particles, and a disperse spray of water is projected onto the particles with sufficient gentleness to not deleteriously distract the particles from their downward path.
    Type: Grant
    Filed: July 3, 2002
    Date of Patent: February 11, 2003

The slurry is received in the mullor/mixer, mixed with return sand, and then discharged for use in making foundry molds. Preferably, the particulate bond material is added to the pre-mix tank as a failing stream of such particles, and a disperse spray of water is projected onto the particles with sufficient gentleness to not deleteriously distract the particles from their downward path.
