Definition Wet scrubbers accomplish particulate collection by employing water or another liquid as the collection media. There are many scrubber designs, but most particulate scrubbers work by creating a wetted target for particle collection. This wetted target plate can be a bed of water or a zone where the particle and water droplet collide. Benefits […]

Baghouse collectors: an overview
Mining Doc
Introduction Baghouse dust collectors capture the particulate in an air stream by forcing the airflow through filter bags. A baghouse works by taking the inlet dust-laden air and initially reducing the velocity to drop out larger particles. The baghouse then filters the remainder of the particles by passing the air through a fabric bag. Separation […]

Reverse air collectors: an overview
Mining Doc
Reverse air collectors use a traveling manifold to distribute low-pressure cleaning air—3–7 pounds-force per square inch gauge (psig)—to the filter bags for reconditioning. They have no compressed air requirements and involve no freezing of air lines. On the negative side, they have larger footprints than conventional collectors and maintaining their cleaning mechanisms is difficult. They […]

Mechanical shaker collector
Mining DocMechanical shakers use a mechanical rapping device to remove the excess dust cake; however, the airflow through the collector must be temporarily stopped to clean the bags. These shakers involve low maintenance and low operating costs, but they require large amounts of space, have limited design flexibility, and have low air to cloth ratios (2:1). […]
Important influence factors of cut blasting
Mining DocCutting blasting is the key to the blasting excavation of rock tunnel, and the main factors influencing the blasting effect are the cutting method and blasting parameters. Cutting blasting is a physical and chemical process of rock and explosive, which is accompanied by high temperature, high pressure and high strain. There are four main factors […]
Collector discharge devices
Mining DocIntroduction The dust collected in a baghouse falls into a hopper below the bags. This hopper must have a discharge device that not only releases the accumulated dust but also ensures a seal between the baghouse and outside air to maintain negative pressure within the unit. Common hopper waste discharge devices available for baghouses are […]
The challenges of scaling operations in underground mines
