The cement industry is an industry within which we excel in solving many process and storage problems in both preventing the build-up of particulate, for example within plant Boilers, ID Fans, Filters, ESPs etc and in ensuring that product does not cause blockages and poor flow, for example within Bins, Silos & Hoppers, Mixers etc.
Calciners: Acoustic cleaners can aid hot air flow through the range of modern calciners and prevent material bridging in both the unit itself and ductwork.
Dynamic Cyclones: These can be prone to impeller blockage and damage which in turn can lead to cyclone blockages and prevent efficient up-stream equipment operation. Acoustic cleaners maintain correct airflow and efficient solids separation by eliminating particulate build up.
Grate Coolers: Blockages here are a real challenge, whether with a fixed or dynamic inlet section. A single acoustic cleaner can replace a multi air cannon installation. Unlike air cannons, an acoustic cleaner actually prevents the occurrence of build-ups and continually aids thick bed material flow. In addition, it eliminates the need for large volume of air produced by air cannons and therefore does not disturb the operation of the kiln
Kiln Inlet: Acoustic cleaners prevent particulate build up and these benefits could be applied at the kiln inlet to help prevent nose ring formation
Mechanical Pre Collectors: Particulate build up in these units significantly reduces their efficiency and can place additional dust loading onto the electrostatic precipitator or filter. Acoustic cleaners can prevent particulate build up around the impellers and between tubes, thus ensuring that they always operate to maximum efficiency.
Mills: Acoustic cleaners can maintain material flow and prevent blockages in the pre-grind silos. They can also be highly effective in preventing material build up in the downstream separators and fans. The positive end result is to provide even, consistent material flow, which results in consistent quality.
Planetary Coolers: Those kiln systems, which still retain this type of cooler, would benefit from the installation of acoustic cleaners to prevent bridging and ensure complete evacuation.
Pre Heaters: Acoustic cleaners can be employed within the towers, gas risers, cyclones and fans to provide highly effective, remote and automatic cleaning by preventing the material build up from occurring in the first place
Static Cyclones: Acoustic cleaners prevent blockages and prevent material build up both within the cyclone and the associated ductwork, thus ensuring constant air flow and maximum particulate removal.
These are some of the process areas where Primasonics acoustic cleaners have successfully been employed within the Cement Industry. The list is not exhaustive, indeed should any facility incorporate a power generation plant then remember that Primasonics acoustic cleaners have also been successfully employed in boilers, superheaters, economizers and air heaters.
