在增产节约、增收节支运动中,煤炭洗选加工行业大都致力于改革产品结构,生产适销对路产品,以增加企业经济效益,而对于一些新工艺却往往重视不够。浮选精煤脱水采用新型助滤剂即是增加经济效益的措施之一。目前绝大部分选煤厂尚未推广应用。为使新型助滤剂能在煤炭加工工业中发挥更大作用,本文着重介绍新型助滤剂的研制与应用情况。一、新型助滤剂的研究 1、研究课题的提出我国选煤厂中,广泛采用圆盘真空过滤
In increasing production and saving, increasing revenues and reducing expenditure, most of the coal washing and processing industries are devoted to reforming the product structure and producing marketable products to increase the economic benefits of enterprises. However, they often fail to pay enough attention to some new processes. Flotation coal dewatering using a new filter aid is one of the measures to increase economic efficiency. At present, most coal preparation plant has not yet been popularized. In order to make the new filter aid to play a greater role in the coal processing industry, this article focuses on the development and application of new filter aid. First, the new filter aid research 1, research topics proposed Coal preparation plant in China, widely used disc vacuum filtration
