I don't know why it has taken me almost 40 years to ask for a guided tour of IMCO. I guess I just needed a productive place to use the photos. My friend Scott was happy to show me around. He has worked there for as long as I have been hauling all this stuff.
Of course, I wanted to see the clay mixing equipment first. IMCO'S clay mixer blends in 2000 pound batches, whereas mine tops out at 150 pounds. A de-airing pugmill is said to produce an effect equivalent to 6 months of aging on the clay. Without either aging or pugging, a freshly blended clay body is pretty much unworkable. IMCO's machine is a brute, which exerts a vacuum pressure I can only envy.
Most of the facility is dedicated to grinding and blending non-plastic materials (no clay content), especially slate, for various industrial applications. The vast network of chutes, drive belts, vacuum ducts, plumbing, hydraulics, electrical, and I don't know what all, make for great imaginative fodder.
