Comminution circuits for gold ore processing ScienceDirect
Publisher Summary. For the vast majority of ounces of gold produced, comminution costs in the form of power, grinding media, and liners represent the single largest cost category of milling. Since, semi-autogenous grinding (SAG) ball-mill circuits represent the single largest type of gold milling comminution circuits, the chapter Roll Crushers. A. Gupta, D.S. Yan, in Mineral Processing Design and Operation, 2006 6.1.3 Roll Crusher Circuit Design. Roll crushers are generally not used as primary crushers for hard ores. Even for softer ores, like chalcocite and chalcopyrite they have been used as secondary crushers. Choke feeding is not advisable as it tends to produce particles of Crusher an overview ScienceDirect Topics

Crushing Plant Design and Layout Considerations 911 Metallurgist
Mine haul-truck capacity is an important factor at primary crusher installations, because it is cost-effective to integrate truck cycle time at the crusher station with mine/shovel operations. If a primary crusher dump pocket is undersized and unable to handle the mine’s trucks, then operators must slowly meter the ore into the receiving hopper.The semimobile primary crushing station can effectively reduce the transportation distance and transportation cost of ore. (3) Mobile primary crushing station (Fig. 2 ) first appeared in limestone mines in the 1950s, which was generally located near the stope working face and moved with the advance of mining operation.Primary Crushing Station SpringerLink
