Jul 01, 2011· Raw meal fineness. There are no rigid standards for raw meal fineness. It is determined empirically and should be as coarse as a given kiln system can tolerate. Typically, a raw meal is ground to about 15% residue on 88 μm sieve and correspondingly to 1.5–2.5% residue on 212 μm.

Jul 24, 2016· Typically, raw meal should be ground to 15% +170# (88µ) and 1.5-2.5% +50# (300µ). A narrow particle size distribution is optimal because fines tend to increase dust loss by entrainment in exhaust gas, while coarse particles are harder to react in the kiln and result in high free lime, and/or excessive fuel consumption.

Sep 01, 2019· In the cement manufacturing process, the particle size of the raw meal is expressed as sieving residues. A higher value indicates a coarser product. The powder with sieving residues higher than a prescribed value indicates a poor raw meal feeding for the following calcining process, resulting in high energy consumption and low product quality.

"Ask dr cleland" feature is for people in the cement industry around the world to ask for his advice. The idea of the feature is that lots of people ask Dr Clark for his advice on issues they are currently facing. The "kids" of the IKN grate must be restricted. Inadequate air flow through the grate will lead to …

Raw Meal extracted from the silo (now called Kiln feed) is fed to the top of the preheater for pyroprocessing. Slide 33: CLINKERISATION Cement Clinker is made by pyroprocessing of Kiln feed in the preheater and the rotary kiln.

Raw Mill Parameters 1.1 Feed Size The largest particle size should be maximum 3 - 4% of the roller diameter Typical feedsize distribution: passing 100mm 95% passing 60mm Maximum 10% passing 1mm Reducing feedsize can increase production, but avoid excessive fines which can increase vibration 1.2 Table Speed

onto the raw mix conveyor. Unfortu-nately, with the limestone extracted from the quarry near Titan, as the particle size changed, the chemistry of the material changed; in particular, the silica content varied substantially across the particle size range. As the level in the blended limestone silo changed, the particle size distribution
