Foundry Sand Muller

A machine for mixing sand and binders by a kneading and squeezing action for use in sand molds. The mixture is usually sand, clay, and water, but synthetic chemical binders may be used.A Muller is a device used to mix casting sand to make it usable for casting. The idea is to mix the sand with the clay to give the sand grains a uniform coating of clay to achieve maximum binding and still leave it porous enough to allow the hot gasses to escape.Müller cells are living optical fibers that guide light through the inner retinal tissue. Thereby they enhance the signal/noise ratio by minimizing intraretinal light scattering and conserve the spatial distribution of light patterns in the propagating image.Foundry sand consists primarily of clean, uniformly sized, high-quality silica sand or lake sand that is bonded to form molds for ferrous (iron and steel) and nonferrous (copper, aluminum, brass) metal castings.
