plant, crushed ore stockpile. The live capacity of the stockpile is approximately 10,000 tonnes. Crushed material is withdrawn from the in-plant stockpile via three apron feeders situated below the stockpile. Ore is conveyed from the apron feeders to the SAG mill by conveyor 02-CVR-01. The ore is milled in a 6 MW, semi-autogenous

Abstract. Actual physical models and discrete element method are used to analyze stress-strain state of broken rocks at the moment when an apron feeder starts discharge from floor storage. It is shown that conventional designs of discharge units of floor storages fail to eliminate broken rock dilatancy which is a determinant of the peak load on ...

Figure 1: Belt or Apron Feeder . In the case of vibratory feeders, there is a tendency for feed to occur preferentially from the front. To overcome this problem, it is recommended that the slope angle of the front face of the hopper be increased by 50 to 80 as illustrated in Figure 2. Alternatively, the lining surface of the front face in the
