Read Onoptimization of cement clinker grinding circuits a task with large economical and environmental perspectives. Predictive control of cement processes inclu-ding the grinding circuits has been reviewed by S anchez and Rodellar (1996). Studies of resi-dencetime distribution forthe transportof charge through continuous ball mills have concluded that
Read OnThe benefits of using limestone as a partial replacement of Portland cement (PC) are well established in the literature. Economic and environmental advantages by reducing CO 2 emissions are well known. This paper describes the influence of the producing method (intergrinding or separate grinding) and particle size distribution on properties of Portland …
Read OnAs considering economy, the cement resulted in the way of adjusting the particle-size distribution through separately collecting the fineness cement in the regular cement-grinding process of normal cement production line without …
Read OnThis paper describes the influence of the producing method (inter-grinding and separate grinding) and particle size distribution (PSD) on early-age properties of binary and ternary blended cements. Various experiments were carried out to determine properties of cement paste including normal consistency, time of setting, heat of hydration and ...
