文章描述了干法预处理低品位硅藻土原料的试验过程。从各种品位得到的硅藻土产品作为助滤剂被用于饮料工业中的预涂滤层。本文进行了如下的研究:1.原料的特性(化学、矿物及颗粒组成等);2.硅藻土原料及中间产品恰到好处的选择性破碎研究;3.硅藻土空气分级好处的研究。以上述研究为基础,研究出了生产不同的硅藻土产品的干法加工技术。
The article describes the dry pretreatment of low-grade diatomite raw materials of the test process. Diatomaceous earth products obtained from various grades are used as prefiltering layers in the beverage industry as filter aids. In this paper, the following studies have been carried out: 1. The characteristics of raw materials (chemical, mineral and particle composition, etc.); 2. Selective crushing studies of diatomite raw materials and intermediate products; 3. Based on the above research, the dry process technology for producing different diatomite products has been developed.
