Abstract
Ovaj rad prikazuje rezultate terenskog mjerenja energije drobljenja na eksploatacijskom polju „Očura“. Hipoteza rada je da smanjenjem veličine čestica raste energija potrebna za njihovo sitnjenje. Na separacijskom postrojenju eksploatacijskog polja „Očura“ uzorci su drobljeni u čeljusnoj (primarnoj), konusnoj (sekundarnoj) i udarnoj (tercijarnoj) drobilici. Pomoću mjernog sustava mjerena je potrošnja električne energije elektromotora prilikom drobljenja u pojedinim drobilicama. U čeljusnoj drobilici izdrobljeno je 16 pojedinačnih uzoraka te je određivana njihova specifična energija. U konusnoj i udarnoj drobilici izdrobljen je materijal iz čeljusne drobilice, ali odjednom. Uspoređivana je specifična energija drobljenja u čeljusnoj, konusnoj i udarnoj drobilici. Statističkom analizom utvrđivana je ovisnost između mase uzorka, specifičnoj energiji drobljenja, prosječnoj snazi drobljenja i maksimalnoj snazi tijekom drobljenja.
Abstract (english)
This thesis shows the results of crushing energy measurements on the field on „Očura“ surface mine. The hypothesis of the thesis is that lowering the particle size raises the energy needed for their comminution. Samples of rock were crushed in jaw (primary), cone (secondary) and impact (tertiary) crushers on the „Očura“ processing plant. Electrical energy consumption of the crushers motor was measured with the measuring system during sample crushing. In the jaw crusher, 16 individual samples were crushed and their specific crushing energy was calculated. In the cone and impact crushers the material form the jaw crusher was crushed all at once. Specific crushing energy of jaw, cone and impact crushers was compared. Dependence between samples mass, specific crushing energy, average crushing power and maximum crushing power was determined by statiscial data processing.
