3 layers silica sand dryer drawing

The unused OH-face of aluminum sheet of the silica and aluminum sheet unit in the Kaolinite clay structure may attract the unsatisfied face of another silica sheet to make a three layer stack and shown in Figure 3.4 and SEM image is illustrated in Figure 3.5 . This makes the basic unit of Montmorillonite clay structure with the thickness of

    Sand, perlite, grog, and vermiculite contain free silica and are, therefore, highly toxic by inhalation. Vermiculite is also frequently contaminated with asbestos. There is a danger of accidents if clay or water can be added while the mixer is in operation. Bags of clay and glaze materials can be very heavy, and lifting can cause back problems
