Cement manufacturing offers particularly difficult challenges to dust collection. Based on data from installations, it’s been estimated that as much as 1% of mining throughput can be lost to the surrounding environment. For a 700 TPH quarry, that’s about seven tons per hour lost from conveyors, crushers and screens, and that does not include losses from stockpiles.
The most obvious dust generation points may seem to be conveyor transfer points and feed points from screens and crushers. But often, oversized feed-outs from screens or transfer of large product into bins will generate significant dust.
