Description
Fremgangsmåte til brikettering av malmer. Procedure for briquetting ores.
Det nye ved oppfinnelsen består deri] at det til de findelte malmer tilsettes et bindemiddel som består av en findelt leire-kalkblanding, fortrinnsvis mergel og en oppløsning av sulfater som magnesiumsulfat, jernsulfat i vann, stivelse og en opp-løsning av hydroksyder som kaliumhy dr ok-syd, natriumhydroksyd i vann. Etter at disse bestanddeler er blitt intimt blandet med den findelte leire-kalkblanding, blir blandingen knadd og presset til briketter. The novelty of the invention is that a binder is added to the finely divided ores, which consists of a finely divided clay-lime mixture, preferably marl and a solution of sulphates such as magnesium sulphate, iron sulphate in water, starch and a solution of hydroxides such as potassium hydroxide ok-syd, sodium hydroxide in water. After these ingredients have been intimately mixed with the finely divided clay-lime mixture, the mixture is kneaded and pressed into briquettes.
I henhold til en foretrukken utførel-sesform av oppfinnelsen går man frem på følgende måte: Mergelen findeles til en partikkelstør-relse på under 5 mm. Det anvendes mergel som har et innhold av CaCOs på ca. 50— 90%. Magnesiumsulfat (MgSCk) løses opp i varmt vann av ca. 50—100° C, i en mengde av 5g MgS04 til 1 liter vann. Av denne MgSOi-oppløsning tilsettes 1 %, altså ca. 10 ml, til hver kg mergel under blanding. Fuktighetsinnholdet av mergelen med tilsetning skal ikke være høyere enn ca. 10 %. According to a preferred embodiment of the invention, the process is as follows: The marl is crushed to a particle size of less than 5 mm. Marl is used which has a CaCO content of approx. 50— 90%. Magnesium sulfate (MgSCk) is dissolved in warm water by approx. 50—100° C, in a quantity of 5g MgS04 to 1 liter of water. 1% of this MgSOi solution is added, i.e. approx. 10 ml, for each kg of marl during mixing. The moisture content of the marl with addition must not be higher than approx. 10%.
Ennvidere blir kaliumhydroksyd (KOH) Furthermore, potassium hydroxide (KOH) becomes
løst opp i varmt vann, nemlig ca. 10 g KOH pr. liter vann. Denne KOH-oppløsning settes til en stivelse som sagostivelse, potet-stivelse, maisstivelse osv., og dette i en mengde av ca. 10 g pr. kg stivelse. Denne blanding settes til den med MgSCU behand-lede mergel, og dette i en mengde av ca. 50 g pr. kg mergel. dissolved in hot water, namely approx. 10 g KOH per liters of water. This KOH solution is added to a starch such as sago starch, potato starch, corn starch, etc., and this in an amount of approx. 10 g per kg of starch. This mixture is added to the MgSCU-treated marl, and this in an amount of approx. 50 g per kg of marl.
Denne blanding opphetes til ca. 50° C. This mixture is heated to approx. 50° C.
Ca. 4—6 % av blandingen beregnet på ■nalmvekten settes til malmen og blandes ■ntimt med denne. Deretter blir malmen med tilsetning behandlet i et knaverk og presset i en briketteringspresse ved ca. 75° C eller høyere. About. 4-6% of the mixture calculated on the ■alm weight is added to the ore and mixed closely with it. The ore with addition is then processed in a knave mill and pressed in a briquetting press at approx. 75° C or higher.
Ved hjelp av det nye bindemiddel opp-nås det en bedre binding av briketten enn med de kjente bindemidler, og pressene blir ikke tilsmurt. Dessuten får brikettene en glatt overflate. With the help of the new binder, a better binding of the briquette is achieved than with the known binders, and the presses are not smeared. The briquettes also have a smooth surface.
Ved tilsetningen av kaliumhydroksyd til stivelse blir stivelsens bindekraft ytterligere forhøyet. By adding potassium hydroxide to starch, the starch's binding power is further increased.
Ennvidere kan det til massen som skal briketteres ytterligere settes ca. 0,2 % eller Furthermore, to the mass to be briquetted, approx. 0.2% or
noe mer eller mindre parafin som hydro-fobt middel. something more or less paraffin as a hydrophobic agent.
På grunn av det høye kalkinnhold i det nye bindemiddel blir den ved forhyttings-prosessen erholdte slagg meget høyverdig til fremstillingen av gjødningsmidler. Due to the high lime content in the new binding agent, the slag obtained in the recoating process is very valuable for the production of fertilisers.
Hvis det i stedet for mergel anvendes en annen leire-kalkblanding, blir den findelte leire og den findelte kullsure kalk blandet intimt med hinannen, og frem-gangsmåten utføres forøvrig på den samme If a different clay-lime mixture is used instead of marl, the finely divided clay and the finely divided carbonated lime are intimately mixed with each other, and the procedure is otherwise carried out in the same way
måte som beskrevet foran. I leirekalkblan-dingen utgjør bindemidlets innhold av kalk ca. 20—60 vektsprosent og av leire ca. 80— 40 vektsprosent. De andre bestanddeler av way as described above. In the clay-lime mixture, the binder's content of lime amounts to approx. 20-60 percent by weight and of clay approx. 80— 40 percent by weight. The other constituents of
blandingen anvendes i passende mengde-forhold. Det kan naturligvis anvendes for-skjellige leire-kalkblandinger. Andre leire-kalkblandinger kan også komme til an-vendelse ved siden av mergel. the mixture is used in appropriate proportions. Naturally, different clay-lime mixtures can be used. Other clay-lime mixtures can also be used alongside marl.
Det er ovenfor beskrevet foretrukne utførelsesarter av oppfinnelsen, men andre utførelser er mulig innenfor rammen av oppfinnelsen. Preferred embodiments of the invention have been described above, but other embodiments are possible within the scope of the invention.
