我厂选矿车间破碎流程,按原设计要求,进入粗碎前的最大粒度为350毫米,但由于矿山采矿方法及井下运输等多种原因,运进选厂矿石最大粒度均超过350毫米,有的高达800～900毫米,从而造成矿石在受矿仓下漏斗处卡壳。工人为了(扌通)下大块,得花费1～3个小时,甚至停产;大块给到皮带上有时滚下来,造成工伤或打坏皮带支架等事故。 According to the original design requirements, the maximum particle size before rough crushing is 350mm. However, due to various reasons such as mine mining methods and underground transportation, the maximum particle size of ore beneficiation plants exceeds 350mm, and some As high as 800 ~ 900 mm, resulting in ore by the funnel at the funnel Department stuck. Workers in order to (扌 pass) under the big block, it takes 1 to 3 hours, or even discontinued; chunks to the belt sometimes roll down, resulting in injuries or damage to belt brackets and other accidents.
