Abstract
Przedmiotem zgłoszenia jest granulowany środek wapnujący, który charakteryzuje się tym, że zawiera w swoim składzie dolomit zmielony w ilości od 94 do 98% mas., lignosulfonian magnezu w ilości od 0,25 do 2% mas., siarczan magnezu w ilości od 0,6 do 2% oraz wodę w ilości od 1,0 do 3% mas. Zgłoszenie obejmuje też sposób wytwarzania granulowanego środka wapnującego z mączki dolomitowej, polegający na tym, że kamień dolomitowy rozdrabnia się do rozmiaru cząstek przechodzących przez sito o wymiarach oczek kwadratowych 0,5 mm, z czego co najmniej 80% przechodzi przez sito o wymiarach oczek kwadratowych 0,2 mm, po czym otrzymaną mączkę dolomitową granuluje się w sposób ciągły przy użyciu granulatora bębnowego lub talerzowego w obecności cieczy granulacyjnej, po czym wilgotny granulat suszy się do wilgotności poniżej 5% mas., a następnie poddaje się klasyfikacji sitowej, oddzielając granule o wielkości od 2 do 6 mm, zaś nadziarno kruszy się do rozmiarów poniżej 1 mm i zawraca się łącznie z podziarnem do procesu granulacji. Przedmiotowy sposób charakteryzuje się tym, że jako ciecz granulacyjną stosuje się roztwór wodny lignosulfonianu magnezu i siarczan magnezu, przy czym stosunek masowy lignosulfonianu magnezu do siarczanu magnezu w roztworze granulacyjnym zawiera się w zakresie od 1 : 1 do 1 : 3, zaś łączne stężenie lignosulfonianu magnezu i siarczanu magnezu w roztworze granulacyjnym wynosi od 8% do 20 % mas.The subject of the application is a granulated liming agent, which is characterized in that it contains ground dolomite in an amount of 94 to 98% by mass, magnesium lignosulphonate in an amount from 0.25 to 2% by mass, magnesium sulphate in an amount from 0, 6 to 2% and water in an amount of 1.0 to 3% by mass The application also includes a method of producing granulated liming material from dolomite flour, in which the dolomite stone is crushed to the size of particles passing through a 0.5 mm sieve, of which at least 80% passes through a 0 mm sieve , 2 mm, after which the obtained dolomite flour is granulated continuously using a drum or disk granulator in the presence of a granulating liquid, after which the wet granulate is dried to a moisture content below 5% by mass, and then sieved, separating granules of the size from 2 to 6 mm, and the oversize crumbles to sizes below 1 mm and is recycled with the sub-grain to the granulation process. The subject method is characterized in that an aqueous solution of magnesium lignosulfonate and magnesium sulfate is used as the granulation liquid, the mass ratio of magnesium lignosulfonate to magnesium sulfate in the granulation solution being in the range from 1: 1 to 1: 3, and the total concentration of magnesium lignosulfonate and magnesium sulfate in the granulation solution ranges from 8% to 20% by weight
