In the case of the dust collected at the cement mill filter, the R90 μm residue showed an average value of 3.93%, and R64 μm was about 11.92%, while the dust from the separator filter showed an R90 μm residue of about 0.2% and an average R64 Rm residue of 0.66%, which means that most of the dust particles have dimensions below these values.
Cement kilns are used for the pyroprocessing stage of manufacture of portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.

how to control residue in ball mill in cement plant. Raw Material Preparation - Cement Plants and … From the early 1900s, both for cement grinding and for grinding hard raw materials, whether by wet or dry process, the standard arrangement was a ball mill for preliminary grinding (to below 0.75 mm), followed by a tube mill for fine grinding.

This residue material affects the properties of cement, especially its compressive strength. To control the non-cementing material in Portland cement, ASTM standard allows the insoluble residue to be not higher than 0.75%. This limitation is much lower than the allowance provided by the British standard which is 1.5%.

Water Spray in Cement Mills. Water spray installed generally in second compartment of ball mill to control cement temperature. Cement discharge temperature should be kept below about 110 o C but, the same time should allow some 60% dehydration of gypsum to optimize cement strength without excessive false set.
Re: Cement mill Residue Dear Mr Jatin, You have not mentioned circuit of your mill.I assume that it might be a closed circuit cement mill. Best possible way to reduce residue on 45micron is by increasing circulation factor across the mill.The other way is to decrese cut size of your dynamic separator by increasing cage rotor speed. R.M.SAHU, INDIA
Elemental Analysis of Cement. Eltra. Applications. Knowledge Base. To produce high-quality cement, the mineralogical and chemical composition of raw materials as well as intermediate and finished products has to be determined. At each stage of the production, samples have to be taken, processed and analysed to ensure quality control without gaps.

A few of them are, The first auto kiln control system based on fuzzy logic in India, The world's largest cement and slag grinding Vertical Roller Mill during 1997,The second such Cement Vertical Roller Mill during 2001, The third Cement Vertical Roller Mill again with 60% additional capacity and first in the world market in 2005.
Therefore, cement particle distribution is the key part of cement production quality control. When the cement fineness is relatively small, 80 and the sieve residue cannot reflect the grinding condition, so 32 or 45 & M should be used as the quality control standard.
Coal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300°C. Inert kiln exhaust gases with oxygen content ...
