Specific surface is a measure of the total surface area of the particles in a given mass of cement: SI unit m 2 /kg. Assuming spherical particles of cement, the mass of a particle of diameter D μm is M = 3150 × π D3 /6 × 10 -18 kg (for particle density 3150 kg/m 3), and the surface area is A = π D2 × 10 -12 m 2.

On-line real-time particle size measurement system Generally we can say that if a cement plant has a capacity < 50 Tonnes/Hour then a simple system incorporating only a single sampling eductor is required. A primary auger must be used to extract a representative quantity of sample, which can thence be sub-sampled for greater quantities of cement.

06.05.2011· Re: Function of classifying liner in 2nd chamber. To break bigger size particles you require bigger balls and vice-a veras.(Size of material is big in 1st chamber where bigger size balls are used).The size of particle at the discharge of 1st diaphragm and begining of 2nd chamber is small.This has to be rduced progressively to finer state.
Industrial versus Laboratory Clinker Processing Using
Unlike industrial mills, laboratory grinding mills operated over given time interval do not account for CL, therefore leading to different cement particle size distribution (PSD) curves [11, 12]. This consequently alters cement properties such as water demand, rheology, and hydration processes such as heat release, setting time, volume change, and strength development [ 13,14 ].
