Handling and processing of basic materials often come with unrequested dust emissions. Sometimes, a massive mechanical stress (crushing) is necessary, and dust generation can not be avoided. Consequently, the emitted dust fraction must be collected and separated from the ambient air to eliminate nuisance and health risks.
Air filtration equipment like bag filters, cyclones and scrubbers have to withstand the respectively rough environments. Besides the reliable compliance with clean gas requirements, high durability and a low wear design are essential. Sensitive components should be avoided. Due to plant sizes and depending on application, explosion and fire suppression must be provided.
