CLINKER GRINDING IN CEMENT PRODUCTION

Clinker (in cement industry) is transitional product in cement production. Upon heating mixture obtained from limestone (about 75%) and clay (about 25%) partial melting occurs and clinker granules are formed. Clinker and gypsum (about 5 %) are mixed and finely milled to obtain cement. Gypsum control the setting properties of the cement.

Clinker Substitution Cembureau

The use of other constituents in cement and the reduction of the clinker-to-cement ratio means lower emissions and lower energy use. Ordinary Portland cement can contain up to 95% clinker (the other 5% being gypsum). The current average clinker-to-cement ratio over all cement

Chemicl parameters defining clinker composition

Lime Saturation Factor (LSF) The Lime Saturation Factor is a ratio of CaO to the other three main oxides. Applied to clinker, it is calculated as: LSF=CaO/(2.8SiO 2 + 1.2Al 2 O 3 + 0.65Fe 2 O 3) Often, this is referred to as a percentage and therefore multiplied by 100. The LSF controls the ratio of alite to belite in the clinker.

Difference between Clinker and Cement Civil Engineering

Clinker Cement; 1: Clinker is a nodular material which is used as the binder in cement products. Cement is a binding agent that sets and hardens to adhere to building units such as stones, bricks, tiles etc. 2: Clinker is a granular substance containing spherical pellets of diameter 3-25 mm.

Optimal fluorite/gypsum mineralizer ratio in Portland

The results obtained in the simulation showed the same behavior as the experimental results. The behavior obtained showed that increases in fluorite and temperature led to decreased free lime in the clinker, while the lowest fluorite/gypsum ratio (2/15) improved clinkering (green areas).
