Raw Material Preparation

A breakthrough in dry blending occurred in the 1950s, when Fuller developed the air-fluidised blending silo (patent US 2844361: 1958). Compressed air is injected into the silo through porous pads in the base, causing the raw meal to become fluidised.

In commonly existing configuration, this dust is transported to blending silo with raw meal when raw mill is running and when raw is stopped for more than two hours the dust is transported to a surge bin. From surge bin the kiln dust can be either transported to silo or fed carefully at controlled feed rate with kiln feed to kiln.

So I am sorry to say that a value of 1.2 is almost no blending at all. However, this does not necessarily mean that there is a problem with the variability of the kiln feed. In the special case where the chemical variability of the raw meal being fed into the homogenising silo is already very low and the same as that of the kiln feed exiting
