Granulated liming agent and method for producing granulated liming agent from ground dolomite

摘要

the object of the application is wapnuju0105cy granular measure, which is characterized by the fact that contains in its composition dolomite ground of from 94 to 98%.lignosulfonate, magnesium in quantities of from 0.25 to 2% mas., magnesium sulphate in quantities of from 0.6 to 2%, and water in quantities of from 1.0 to 3%.the application also includes a way to produce granular measure wapnuju0105cego meal dolomitowej, namely thatthat stone dolomitowy is chopped to particle size passing through a sieve of mesh size of 0.5 mm.of which at least 80% to pass through a sieve of mesh size square 0,2 mm,after what the meal dolomitowu0105 granuluje in continuously using granulatora lining or talerzowego in the presence of liquid granulacyjnej,after the wet granules dried to a moisture content below 5%.and then subjected to classification sieve separating granules size from 2 to 6 mm,and nadziarno crumbles to the size below 1 mm and turns together with podziarnem to granulation process.the method is characterized by the fact that as a liquid granulacyjnu0105 apply aqueous solution lignosulfonianu magnesium and magnesium sulphatethe mass ratio lignosulfonianu magnesium to magnesium sulfate in solution granulacyjnym contains in the range from 1: 1 to 1: 3.the total concentration lignosulfonianu magnesium and magnesium sulfate in solution granulacyjnym ranges from 8% to 20%.
