Abstract

Abstract The Bureau of Mines and several member companies of the National Industrial Sand Association have been working in many areas to reduce personal exposure to respirable dust. Areas investigated have included ventilation, improved hardware design, improved housekeeping practices, and addition of moisture to products. This article reviews information to date on various methods of using moisture to reduce respirable dust concentrations in mineral processing plants. Individual studies present an inconclusive case for additional work in this area. Together, however, these studies indicate a good potential for the development of an economical and practical plantwide dust control technique. Naturally, these techniques may only be applicable for certain mineral products. Methods used in the individual studies to evaluate dust reductions included observation, gravimetric filter analysis, and instantaneous light-scattering methods. Various methods of moisture addition included the use of foams, steam, and wa...

湿度应用于粉尘控制
矿产局和国家工业砂协会的几家成员公司一直在许多领域开展工作,以减少个人接触可呼吸性粉尘。调查的领域包括通风、硬件设计的改进、内务管理的改进以及产品水分的增加。本文综述了迄今为止关于利用水分来降低矿物加工厂呼吸性粉尘浓度的各种方法的信息。个别研究对这一领域的额外工作提出了不确定的理由。然而,这些研究表明,发展一种经济实用的全厂粉尘控制技术具有良好的潜力。当然,这些技术可能只适用于某些矿物产品。在个别研究中用于评估降尘量的方法包括观测、重力过滤分析和瞬时光散射法。各种增加水分的方法包括使用泡沫、蒸汽和水。
