(54) SPOSOB PŘÍPRAVY PEVNÝCH GRANULÁTOV VHODNÝ NAJMÁ PRE ICH DROBENIE A ZARIADBNIENA JEHO REALIZÁCIU 1(54) PREPARING THE FIXED GRANULATES SUITABLE FOR YOUR SMOKING AND FITTING ITS IMPLEMENTATION 1

Vynález aa týká technologie při drobení pevných granulétov a rieái problém zníženiapráce na rozdrobenie kovov. Váetky doterajšie sposoby ako aj zariadenia na drobenie granulátov, drobia granulátyo takej teplote ako je teplota okolia.The invention relates to a technology for crumbling solid granules and solves the problem of reducing the work of crushing metals. The prior art as well as the granulate crumbling devices break the granulates at a temperature such as ambient temperature.

Nevýhodou týchto riešení je, že výlažnosf na daný příkon zariadení je poměrně nízká aproblémom je i drobenie velmi pevných materiálov.A disadvantage of these solutions is that the yield to the given power input of the devices is relatively low and the problem is also the crumbling of very solid materials.

Uvedené nedostatky odstraňuje sposob přípravy pevných granulátov, vhodný najma pre ichdrobenie, ktorého podstata spočívá v tom, že pevný granulát sa podchladí pomocou tekutýchplynov na teplotu 100 až 150 K a potom sa rozdrobí mlecím zariadením. Podstata zariadeniaspočívá v tom, že pozostáva z chladiče, ktorý je opatřený zásobníkom granulátu. Na chladičje napojený zásobník tekutého plynu a tiež pomocou odvodného potrubia i mlecie zariadenie. Výhoda sposobu, ktorý je predmetom vynálezu je v tom, že podchladením granulátu sa zvý-ši výlažnoat drobenia a dajú sa urobil i velmi pevné materiály. Tieto výhody sú výsledkomtoho, Že podchladením granulátu na teplotu blízku teplote tekutých plynov, lomová húževna-tosi niekolkokrát poklesne oproti lomovej húževnatosti granulátu pri teplote okolia, granu-lát se stává křehkým, čím sa potom zvýši účinok drobenia.The above drawbacks are eliminated by the process of preparing solid granules, particularly suitable for their hardness, characterized in that the solid granulate is cooled with liquid gas to a temperature of 100 to 150 K and then crushed by a milling device. The essence of the device is that it consists of a cooler provided with a granulate reservoir. A liquid gas reservoir is connected to the cooler and a grinding device is also provided by means of a drain pipe. An advantage of the process of the invention is that by cooling the granulate, crumbling is increased and very solid materials are made. As a result, by cooling the granulate to a temperature close to the liquid gas, the fracture toughness decreases several times over the fracture toughness of the granulate at ambient temperature, making the granulate brittle, thereby increasing the crumbling effect.

Zariadenia na drobenie pevných granulátov je znázorněné na připojeno® výkrese, kde jenakreslené schématicky v nárysnom řeze. 200899A device for crumbling solid granules is shown in the accompanying drawing, where it is illustrated schematically in an elevation view. 200899
