Cement is a hydraulic binder It is a finely ground inorganicmaterial which when mixed with water forms a paste which sets and hardens by means of hydration reactions and processes After hardening it retains its strength and stability even under water The declared cement is Portland cement CEM I 52 5 N according to EN 197 1 Application.May 10 2016 few repairs and little maintenance Portland cement is made by heating limestone (calcium carbonate) with other materials With two crusher s (rotary ha mm er and roll) and total crushing.
The manufacture of Portland cement is a complex process and done in the following steps grinding the raw materials mixing them in certain proportions depending upon their purity and composition and burning them to sintering in a kiln at a temperature of about 1350 to 1500 ⁰C During this process these materials partially fuse to form nodular shaped clinker by broking of chemical bonds of.PEW series Jaw crusher features big crushing ratio reliable operation easy maintenance and low operating cost It is the new generation product designed PFW Impact Crusher offer them the best crusher machine much advanced machinery and better service.
In the most general sense portland cement is produced by heating sources of lime iron silica and alumina to clinkering temperature (2 500 to 2 800 degrees Fahrenheit) in a rotating kiln then grinding the clinker to a fine powder The heating that occurs in the kiln transforms the raw materials into new chemical compounds.2 Raw material preparation In the cement production line producing each 1 ton of Portland Cement need grinding at least 3 tons of materials (including raw materials fuel clinker mixed materials gypsum) Grinding operation consumes power about 60 of total power in cement plants raw material grinding takes than 30 while coal mill used in cement plant consumes 3 cement.
