Cement grinding process standard technical measures

This makes the local cement production enterprises are facing severe challenges. The new standard for the quality of cement made more stringent requirements, especially cement fineness and particle size distribution, the majority of local vertical roller mill technology obviously can not meet this requirement must be cement grinding process and equipment innovation, in order to meet the cement strength standards. Strength properties of cement particles of cement strength of cement paste depends on its chemical composition of mineral composition and physical state, from the perspective of cement grinding, cement particle characteristics have a greater impact on the cement hydration process and strength. Fineness of cement coarse affect the strength to play with cement fineness sieve residue and specific surface area, said local cement companies to use more than a square hole sieve sieve residue and percentages hereinafter referred to control. In contrast to foreign cement is much thinner, I sieve sieve over a cement accounts that I cement fineness sieve sieve almost no remaining. vertical roller mill reasonable particle size distribution of different cement grinding cement grinding system of particle size distribution is different, the same clinker grinding when conditions change, and its particle size distribution also changes, which directly affect cement performance. Reasonable particle size distribution of cement clinker and make active in admixture can be fully tapped and utilized. The particle size distribution of cement production control targets were always listed cement companies. Activity in the full use of cement and improving the performance of Silicon considered existing silicon of ordinary cement fineness of cement particles may have one not involved in the growth process of silicon strength, vertical roller milltoo coarse particles can not fully hydrated, since only the silicon the role of micro-aggregate of particles too fine agglomerate or increased water demand of cement, which causes an increase in the porosity of the alkaline, silicon strength is lowered, which mix the particles in the fully hydrated, to increase the strength of age no effect. So cement particles must have a reasonable particle size distribution, in order to obtain the highest strength.
