5476377 Method and grate cooler for hot bulk material December 19, 1995
The invention relates to the cooling of hot bulk material, particularly cement clinker, ore material or the like, in a grate cooler, in which the bulk material is transported on the cooler grate surface toward an outlet and exposed to cooling gas from below. At least a part of the relati
5437721 Method of producing cement clinker August 1, 1995
The invention relates to a method of producing cement clinker from fine-grained cement raw material which after preheating and calcining is burnt in a clinker burning zone divided into two stages and is then cooled. Optimum process conditions, particularly in the clinker burning zone
5375776 Method and apparatus for the comminution of material for grinding December 27, 1994
The invention relates to the comminution of material for grinding, particularly for the production of cement, wherein the material for grinding is comminuted in a mill and the comminution product is classified in a classification zone into fines and oversize material and the oversize
5219544 Method of purifying the exhaust gases from plants for the production of cement clinker June 15, 1993
The invention relates to a method of purifying the exhaust gases from plants for the production of cement clinker, in which the filter zone through which the exhaust gases flow contains at least one adsorption stage in which an adsorbent is provided which is suitable for fixing NH.su
5169611 Method of purifying the exhaust gases from plants for the production of cement clinker December 8, 1992
The invention relates to a method and apparatus for purifying the exhaust gases from plants for the production of cement clinker, in which in a multi-stage filter zone hot exhaust gases coming from a preheating zone are first of all cleaned of dust in a first filter stage and then in a
5129820 Method and apparatus for cooling fired bulk material July 14, 1992
The invention relates to a method and apparatus for cooling fired bulk material in which the height of the material bed on a grate conveyor in a first cooling zone is set by the conveying speed of the grate and by gravity. Thus in a particularly simple way the height of the material bed
