广西栗木锡矿高屋坪采选厂是一个由400吨/日的老选矿厂扩建成800吨/日的选矿厂。由于设备比较残旧,不配套,流程不完善,加上由原来处理井下矿石改成现在处理露天回采的残矿石,原矿性质发生变化,直接影响了生产。改建两年来,一直是该矿的亏损大户。针对这种情况,1987年初,他们一方面加强生产管理,积极推行承包经营责任制;另一方面对选矿厂不合理的工艺流程进行改进,半年就甩掉了亏损帽子。他们主要采取了五条措施。(一)取消影响生产、消耗高不合理的电动设备。拆除了2台30千瓦的4英寸砂泵,3台7.5千瓦的2.5英寸砂泵,1台7.5千瓦的浓泥振动筛,1台30千瓦的球磨机。全年可节约资金7万元以上。(二)取消选矿流程中作用不大的弧形筛。由于原矿残渣碎屑多,弧形筛筛孔小,容易堵塞,筛分效率低,使处理量难以提高,同时因增加用水
Guangxi Li Mu tin mine Gaozhao Ping mining plant is a 400 tons / day of the old beneficiation plant expanded into 800 tons / day of the concentrator. Due to the equipment is relatively old, not complete, the process is not perfect, coupled with the original treatment of underground ore into the residual ore is now dealing with open-pit mining, the nature of the ore changes have a direct impact on the production. Reconstruction two years ago, has been a big loser of the mine. In response to this situation, in early 1987, on the one hand, they stepped up their production management and actively implemented the responsibility system of contracting management. On the other hand, they improved the unreasonable technological process of the concentrator and eliminated the loss hat in half a year. They mainly adopted five measures. (A) to cancel the impact of production, high consumption of unreasonable electric equipment. Two 30-kilowatt 4-inch sand pumps, three 7.5-kilowatt 2.5-inch sand pumps, a 7.5 kilowatt shale shaker and a 30 kilowatts ball mill were removed. The annual savings of more than 70,000 yuan. (B) to cancel the dressing process is not a big role in the arc sieve. As the original ore debris and more arcuate sieve hole is small, easy to plug, low screening efficiency, so difficult to increase the amount of treatment, while increasing water
