Improving particle size distribution in cement production ...

In the past, cement producers gauged cement fineness (i.e., cement particle size) by evaluating the specific surface area (SSA) or Blaine fineness and the sieve residue at various sizes. However, many producers now use particle size analysis techniques to assess fineness and help monitor the efficiency of the mill. In the traditional Blaine SSA Fineness method, the fineness of cement is ...

Cement mill - Wikipedia

These consist of a pair of rollers set 8–30 mm apart and counter-rotating with surface speed around 0.9 - 1.8 m.s . The bearings of the rollers are designed to deliver a pressure of 50 MPa or more. The bed of material drawn between the rollers emerges as a slab-like agglomeration of highly fractured particles. The energy efficiency of this process is comparatively high. Systems have been designed, including a de-agglomerator and separator, that will deliver material of cement fineness. However, particle size distrib…

Cement Particle Size Analysis - Sympatec

Responsible for quality and uniformity of the different cement types is most of all, (next to the chemical composition of raw materials), the grain size distribution of cement, which is a result of the component’s grinding fineness. If the cement’s chemical composition doesn’t vary, only the grinding fineness determines the strength class: The higher the grade of fineness, the faster the ...

21/08/2020· Determination of cement fineness shall not be limited to only Blaine value or a sieve residue — information on the whole particle size distribution (P.S.D.) must be used. Here the P directly effects the other two P’s — Performance characteristics of cement made and Power consumption to produce the cement.

Cement Kilns: Size Reduction and Grinding

A particle of negligible size and mass m just remains in contact with the mill lining at the "12 o'clock" position if the centrifugal effect (mv 2 /r) is equal to the gravitational force (mg), where v is the peripheral velocity in m/s and r is the radius inside the lining in metres. The circumference of the mill is 2πr metres so v = 2πrN/60 where N is the speed in rpm. Substituting v in the ...
