美国密苏里州沃伦顿石灰石矿用10码~3装载机直接给移动式破碎机给料时,其生产率要比7(1/2)码~3较小型装载机低些。用10码~3装载机供料,似乎来自矿山的矿石量很大,但破碎机容量不够,来不及处理。结果,装载机给破碎机装料需15～20秒钟。这就降低了生产率,而7(1/2)码~3的斗容则是最适用的规格。沃伦顿矿使用一台 Dresser 560BPay 轮 The limestone mine in Warrenton, Missouri, USA, uses a 10-yr-3 loader to feed mobile crushers directly, with a lower productivity than a smaller 7 (1/2) yr-3 smaller loader. With 10 yards ~ 3 loader supply, it seems that a large amount of ore from the mine, but the crusher capacity is not enough, too late to deal with. As a result, the loader charges the crusher for 15 to 20 seconds. This reduces the productivity, and 7 (1/2) yards ~ 3 bucket capacity is the most suitable specification.
