我矿洗选场的主要设备是振动筛和皮带输送机,其运转正常与否,直接影响到生产效率的高低。自1986年投产运行以来,因振动筛网孔过大(15×15毫米),10毫米以下的碎矿均白白丢掉,矿石回收率仅为65%左右。另外,因输送皮带较长(60米),有二分之一长度为坡段,拉紧机构又是软性装置,很难调整其松紧程度。所以在输送物料过程中皮带常打滑,为此而将皮带调整紧些,其接头又易被拉断或脱扣。这些都影响到生产
The main equipment of mine washing field is the vibrating screen and belt conveyor. Whether its operation is normal or not affects the production efficiency directly. Since it was put into operation in 1986, the ore crushed ore is completely lost due to the oversize sieve holes (15 × 15 mm) and the crushed ore below 10 mm. The ore recovery rate is only about 65%. In addition, due to the conveyor belt is longer (60 meters), one-half of the length of the slope section, tensioning mechanism is a soft device, it is difficult to adjust the tightness. Therefore, the process of conveying materials in the belt often slippery, adjust the belt for this purpose, the joints are easily pulled off or trip. These affect production
