The analysis of the state of dust collection in the production of Portland cement is presented. A new scheme of purification of aspiration air from ball mills, when crushing clinker, using slotted filters and jet-filtration dust collector. The description and operating principle of recommended dust collectors are given. This scheme will improve the cleaning efficiency and reduce the hydraulic resistance during dust collection.
