阅读说明：本技术 一种环保高效物理选矿机及双重选矿方法 (Environment-friendly efficient physical concentrator and dual-concentration method ) 是由 吴世瑞 林国桥 于 2021-09-14 设计创作，主要内容包括：本发明公开一种环保高效物理选矿机及双重选矿方法,主要包括由振动筛、综合收料密封罩和数控除尘器组成。综合收料密封罩将整台振动筛及其排料溜槽的大部分包裹起来,其内由上至下,分别设置抽风管、吹风管、隔板、导板、粗矿石溜槽、粗矿砂溜槽、细矿砂收料斗、粗矿粉收料斗。工作时,先由振动筛进行筛分,上层筛网筛选出粗矿石、下层筛网筛选出粗矿砂；细矿砂粉则透过下层筛网,掉在其下的导板,由导板导向振动筛的尾部,再向综合收料密封罩的下部漂下,在抽风气流的作用下,颗粒大降落快,所以,细砂粉随气流进入数控除尘器,并由其下的收料斗收集；颗粒稍大的矿粉,分别漂落在综合收料密封罩下部的细矿砂收料斗、粗矿粉收料斗内。(The invention discloses an environment-friendly high-efficiency physical concentrator and a double-concentration method. The comprehensive material receiving sealing cover wraps the whole vibrating screen and most of the material discharging chute of the vibrating screen, and an exhaust pipe, an air blowing pipe, a partition plate, a guide plate, a coarse ore chute, a coarse ore sand chute, a fine ore receiving hopper and a coarse ore powder receiving hopper are respectively arranged in the comprehensive material receiving sealing cover from top to bottom. When the device works, the device is firstly screened by a vibrating screen, coarse ores are screened out by an upper-layer screen mesh, and coarse ore sand is screened out by a lower-layer screen mesh; fine ore sand powder penetrates through the lower-layer screen mesh, falls off the guide plate below the lower-layer screen mesh, is guided to the tail part of the vibrating screen by the guide plate, then floats to the lower part of the comprehensive material receiving sealing cover, and is subjected to large particle falling speed under the action of air draft airflow, so that the fine sand powder enters the numerical control dust remover along with the airflow and is collected by the material receiving hopper below the numerical control dust remover; and the mineral powder with slightly larger particles floats in the fine ore sand receiving hopper and the coarse ore powder receiving hopper at the lower part of the comprehensive receiving sealing cover respectively.)
