Saw mills generate a lot of dust which must be extracted from the mill. Dust is drawn into the main extraction system by a negative pressure created by a fan usually a centrifugal fan. The dust laden air then passes through a cyclone separator where most of the wood dust is separated from the air stream; the clean air is then discharged ...

After milling, the material is moved to storage silos or slurry tanks until pyroprocessing. In this stage, a pulse jet dust collector and cartridge is needed for the milling process as well as material handling, conveying, and storage processes. STEP TWO COAL GRINDING. Most cement plants today use coal as fuel for the pyroprocessing stage.

Separator particle separation performance is assessed using the Tromp curve, a graph of percentage separator feed to rejects against particle size range. An example is shown in Fig. Data required is the PSD of separator feed material and of rejects and finished product streams. The bypass and slope provide a measure of separator performance.

In a general cement, between 60 and 70% of the material should be between 3µm and 30µm in size. Excess large particles (greater than 50µm) can cause problems by reducing strength due to incomplete hydration, where as excess small particles (less than 2µm) can reduce strength and cause the cement to crack by setting exothermically.
