Oct 28 2013 Dust Control MITIGATION TECHNIQUES The most common methods for controlling demolition dust are surface wetting and airborne capture With surface suppression the goal is to prevent dust problems by wetting the source before particles can become airborne usually with hand held hoses or movable sprinklers (See Figure 1 ).Granite fines or rock dust is a by product obtained during crushing of granite rocks and is also called quarry dust This present work is an attempt to use Quarry Dust as replacement for Sand.
Abstract Crushed stone dust is material obtained from aggregate crushing industries Use of such stone dust materials creates lots of problems in environment and public due to excess storage and dust accumulation Considering this aspect an experimental study was conducted on expansive soil by mixing it with locally available crushed stone dust.The use of water spray bars near crushing operations has been shown to significantly reduce dust problems One research study showed that the use of spray bars resulted in a nearly 50 reduction of dust emissions measured at a distance of 33 ft (10 m) from the crusher (DETR 2000) Other situations that cannot be directly controlled by site.
