An inefficient ball mill is a major expense and could even cost you product quality. The best ball mills enable you to achieve the desired fineness quickly and efficiently, with minimum energy expenditure and low maintenance. With more than 4000 references worldwide, the FL ball mill is proven to do just that.
The resulting clinker (rounded nodules between 1mm and 25mm across) is ground to a fine powder in a cement mill and mixed with gypsum to create cement. The powdered cement is then mixed with water and aggregates to form concrete that is used in construction. Clinker quality depends on raw material composition.

Quality is a term that encompasses a large number of parameters with respect to the product delivered from the flourmill to the baker. Essentially, it means satisfying the baker's requirement for consistent performance from the flour. The challenge for millers is to achieve this while maintaining acceptable performance from the mill. 8.4.1.
A 1.5 mio t/a cement plant is having a closed circuit ball mill for cement grinding: The mill has been operating with satisfactory performance in-terms of system availability and output, however power consumption was on higher side. 3.1 System Description Mill Rated capacity 150 t/h OPC at 2800 blaine I chamber liners
Cement mortar strength and cement concrete strength are not directly related. Cement strength is merely a quality control measure. The tests of strength are performed on cement mortar mix, not on cement paste. Cement gains strength over time, so the specific time of performing the test should be mentioned. Compressive Strength

Section 1 gives a general introduction of the cement ball mill, its quality parameter-the blaine and soft-sensing techniques available in literature to predict it. Nonlinear model development using kernel principal component analysis is dealt with in section 2. Illustrative applications on the development of soft-sensor for blaine from real ...
Cement grinding in the cement mill generates considerable amount of dust. It has been established that about 7–10% of cement may be lost due to uncontrolled emissions from the cement mill. Lines 1&2 and Line 3&4 operate three (3) and four (4) stacks, respectively, all provided with bag house filters.
Quality control of the slurry in the cement industry is based on weight ratio control of raw materials. Raw materials composition is usually assumed constant and know due to difficulties in direct measurement. ... The mill model parameters must be estimated from input/output measurements taken at different rates. The avaible information is: 1 ...
