  • BALL MILL METHOD FOR DETERMINING THE

    11 This method determines the resistance of aggregate in flexible base material to disintegration in the presence of water The test provides a measure of the ability of the material to withstand degradation in the road base and detects soft aggregate that is subject to weathering The result of this test is the Wet Ball Mill (WBM) valueThe result of this test is known as the Wet Ball Mill (WBM) value Apparatus The following apparatus is required: ♦ wet ball mill machine, consisting of a watertight steel cylinder, closed at one end, with inside dimensions of 2588 ± 3 mm (10188 ± 1/8 in) in diameter and 2731 ± 3 mm (1075 ± 1/8 in) in lengthChapter 1 – Soils Tex116E, Ball Mill Method forThe Bond ball mill test is designed to predict power in wet ball mill grinding circuit operating at a 250% circulating load However, moving away from this condition reduces the accuracy of the test Further, the Bond ball mill test does not predict the behavior of large rocks in a grinding circuit where the mode of breakage is impact dominatedTesting method for ball mills Outokumpu Technology Oyj
