Mineral additives are materials which are used in wide range of industries including construction, cosmetics, agricultural and bio technology. Such materials as plasters, paints, abrasives etc. are produced using mineral powders. Main qualities of mineral additives are purity of chemical composition, grading properties and shape factor. To obtain powder like material most common method is milling. One of most effective milling method for refining of brittle material is grinding by collision in disintegrator. One of advantage of this method is that high milling energy is transferred to the milling material in short period of time. In present research three types of mineral materials were treated in disintegrator with specific energy E s applied 8.4 and 25.2 kWh/t: natural quartz sand 0.3/1mm, quartz -limestone 0.3/2.5mm sand and dolomite screenings 0/4mm. Results indicate that powder like material with d90 form 6 6 to 141 µm could be obtained at E s 8.4 kWh/t while increase of E s reduces d90 value to 48 to 72 µm and the milling efficiency was effected by the sand type.
