根据我国地方中小型煤矿急待发展洗选、筛选加工的需要,洛阳矿山机械研究所充分挖掘潜力,设计出了用于中等易选煤的JYX—Ⅰ和 JYX一Ⅱ型机械组合式选煤厂。JYX—Ⅰ和 JYX一Ⅱ型组合式选煤厂,属于年处理15万吨和10万吨煤的简易型选煤厂,主要由原煤运输,筛分破碎和跳汰等设备(不包括煤泥泵和清水泵等)组成。这种组合式选煤厂的生产工艺是:斗式挖运机将原煤挖起并运到筛分机上进行筛分(筛孔为50毫米或20毫米),大于50(或者20)毫米的块煤进入旋转破碎机。破碎后的0～50(或0～20)毫米粒级产品,与筛下物一起在水力作用下沿溜槽进入跳汰机分选。跳汰机选出的矸石和中煤分别由斗子提
According to the urgent needs of our country’s local small and medium-sized coal washing, screening processing needs, Luoyang Mining Machinery Research Institute fully tap the potential, designed for medium easy coal JYX-Ⅰ and JYX a Ⅱ type of mechanical combined coal preparation plant . JYX-Ⅰ and JYX Ⅱ combined type coal preparation plant belong to simple coal preparation plant with annual processing capacity of 150,000 tons and 100,000 tons of coal, mainly including coal transportation, screening, crushing and jigging equipment (excluding slime Pump and water pump, etc.). The production process of the combined coal preparation plant is as follows: a bucket-type digger picks up the raw coal and sends it to a sifter for screening (50 mm or 20 mm holes), blocks of more than 50 (or 20 mm) Coal enters the rotary crusher. Broken 0 to 50 (or 0 to 20) mm particle size products, together with the undersize under the action of the chute along the chute into the jig sorting. Jig and coal were elected by bucket bucket mention
