Pre-homogenization
the chemical composition of limestone depends on the area of operation, this fluctuation causes the crude milling process is more difficult the preparation of the components (limestone, clay, iron) in such a way of having a stable process and a clinker in high quality in the process of calcination.
to do this is, the process of prehomogeneización that offers the following advantages: "Best use of quarry materials"; "Greater uniformity of raw flour and therefore greater regularity of the clinker".
pre-homogeneización method, used is the longitudinal stacking or mixing layers (method Chevron). The material that falls to the base is picked up and moved by a conveyor of buckets that download in a tape that leads him to the hangar downloading directly to the dosing hopper of the mills of crude oil.
