Abstract
A method and apparatus for the production of a hydraulic binder of the type used for plaster and masonry mortar within a cement producing installation including a preheating zone and a clinker calcining zone. In accordance with the invention, the cement producing plant is modified to the extent of providing for the removal of a predetermined portion of the material being processed from at least one point between the preheating zone and the clinker calcining zone wherein the withdrawn material has a predetermined condition of activation so that it is useful alone or in a mixture with other ingredients in the manufacture of the binder.
Claims11
A method for the production of a hydraulic binder of the type used for plaster and masonry mortar in a cement producing installation wherein raw material is processed sequentially through a preheating zone and a heated clinker calcining zone having a raw material inlet and discharging heated exhaust gases into said preheating zone, which comprises:
- removing a predetermined portion of the material being processed from at least one point between the preheating zone and the clinker calcining zone while the material has a predetermined condition of activation at a temperature of at least 450.degree. C.
