Dust treatment in the crushing workshop of the beneficiation plant is a systematic project, which requires specific dust conditions (temperature, humidity, particle size, acidity and alkalinity, cohesiveness, infiltration, etc.), pipeline layout, collection methods, and equipment at specific dust process points. Comprehensive consideration of all aspects such as operating cycle. We have summed up the dust management experience in the crushing workshops of hundreds of mines in quarries, copper mines, iron ore, lead-zinc mines, etc., and put forward the following problems that are prone to dust management in mine crushing workshops.
