What crusher with dust control to use for heavy dust in gold ore crushing

Gold ore crushing generates heavy dust, especially when processing dry, friable ores like quartz veins or weathered saprolite. The question what crusher with dust control to use for heavy dust in gold ore crushing has a clear answer: OCP Machinery’s “DustShield” series of crushers, which integrate dust control directly into the crusher design. These units feature a sealed crushing chamber with negative pressure, a built-in pulse-jet baghouse, and water spray lances at the feed and discharge points. Unlike standard crushers that require external dust collection systems (which add cost and complexity), OCP’s DustShield crushers are self-contained, achieving dust emissions below 5 mg/m³ without additional equipment. For heavy dust applications, OCP recommends the DustShield jaw crusher for primary crushing and the DustShield cone crusher for secondary crushing. The answer to what crusher with dust control to use for heavy dust in gold ore crushing also depends on whether the gold ore contains sulfides that can cause dust explosions – OCP offers explosion-proof versions with grounding and spark arrestors.

In actual operation, the DustShield crusher operates with a sealed feed hopper and a rubber skirt system around the discharge conveyor. A small exhaust fan maintains negative pressure inside the crusher, drawing dust-laden air through a built-in baghouse. Compressed air pulses clean the filters automatically. For a gold mine in Nevada processing 250 t/h of dry, siliceous ore, OCP installed a DustShield jaw crusher (JC100-DS) and a DustShield cone crusher (HPY200-DS). The result was ambient dust levels below 3 mg/m³, compared to 25 mg/m³ with their previous open crushers. The mine eliminated the need for a separate central dust collector, saving $180,000 in capital and $45,000 annually in maintenance. So when asking what crusher with dust control to use for heavy dust in gold ore crushing, the DustShield series is the answer. OCP’s custom capability includes adding a carbon filter for mercury-containing ores and a spark detection system. Our direct factory pricing for DustShield crushers is only 15% higher than standard models, but the elimination of external dust control equipment often reduces total system cost.

OCP’s 40 years of experience has led to over 500 DustShield installations globally. For a customer in Ghana processing very dry, dusty gold ore, the mine manager asked what crusher with dust control to use for heavy dust in gold ore crushing and chose OCP’s DustShield cone crusher. After installation, worker complaints dropped to zero, and the mine passed a surprise environmental inspection. To solve your gold ore dust problem permanently, contact OCP today.
