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material being processed from at least one point between the preheating zone and the clinker calcining zone wherein the withdrawn material has a predetermined condition of activation so that it is useful alone or in a mixture with other ingredients in the manufacture of the binder.
Claims7
An apparatus for production of a hydraulic binder which comprises:
- means defining a preheating zone for particulate material used in the manufacture of cement, said preheating zone including a plurality of sequential stages each stage providing a progressively greater degree of deacidification to the raw material passing therethrough,
- means for introducing raw material into said preheating zone,
- means defining a calcining zone receiving the preheated output of said preheating zone, and
- discharge means between said preheating zone and said calcining zone for withdrawing a portion of the preheated material of a predetermined degree of deacidification which is less than complete deacidification.
