Description
Przedmiotem niniejszego wynalazku jest sposób wyrobu pylu z rodzimych mi¬ neralów do gaszenia ognia i przeciwdziala¬ nia wybuchom w kopalniach. Sposób ten odznacza sie tern, ze w czasie mielenia na delikatny pyl surowego materjalu, którym moga byc ziemie w naturalny sposób wy- mulone i uwolnione od higroskopijnych domieszek (np. gliny), twarde odpryskuja- ce kamienie (np, piaskowce) dodaje sie lupki zawierajace wiele kwarcu, lub inne kamienie bardziej miekkie np, wapniowce (np. weglan wapniowy, lub siarczan wap¬ niowy), przyczem ilosc tych domieszek do¬ biera sie stosownie do mielonego materja¬ lu i dodaje sie je w stanie zupelnie suchym.Mielenie materjalów zupelnie suchych ma na celu unikniecie niedogodnosci, wynika,- jacych z mielenia wiekszych materjalów w stanie wilgotnym.W tym celu materjal surowy i domie¬ szki ogrzewa sie oddzielnie w suszarkach bebnowych, przyczem reguluje sie tempe¬ rature w ten sposób, zeby materjal nie ulegl zadnym zmianom fizycznym lub chemicz¬ nym. Tern zapobiega sie niedogodnosci wy¬ nikajace z tego, ze niektóre mineraly wchlaniajac wilgoc twardnieja. Stosunek mieszaniny róznych gatunków kamienia do¬ biera sie tak, zeby otrzymac pyl o jak naj¬ lepszych wlasnosciach. Równoczesne mie¬ lenie materjalów wlasciwych i domieszek daje lepsze wyniki i jest tansze od oddziel¬ nego mielenia poszczególnych materjalów i mieszania gotowych pylów. PLThe present invention relates to a method of producing dust from native minerals for extinguishing fires and preventing explosions in mines. This method is characterized by the fact that when grinding into a fine dust of raw material, which can be soil naturally mud and free from hygroscopic impurities (e.g. clay), hard stone chips (e.g. sandstones), slides are added containing a lot of quartz or other softer stones, e.g. limestone (e.g. calcium carbonate or calcium sulphate), whereby the amount of these admixtures is selected according to the material to be ground and is added in a completely dry state. completely dry to avoid the inconvenience of grinding larger materials when wet. To this end, the raw material and admixtures are heated separately in tumble dryers, and the temperature is regulated so that the material does not deteriorate. any physical or chemical changes. This avoids the disadvantage that some minerals harden when they absorb moisture. The ratio of the mixture of different types of stone is selected so as to obtain dust with the best properties. Simultaneous grinding of proper materials and admixtures gives better results and is cheaper than separate grinding of individual materials and mixing of the finished dusts. PL
