Industrial lubrication systems in cement plants operate under demanding conditions. Dust contamination, high oil circulation rates and continuous equipment operation can make filtration a surprisingly important part of overall maintenance. A recent cement plant application in Saudi Arabia provides an interesting example of how filtration equipment can be adapted to these conditions. The Application The project involved a 5,000 TPD cement production line and the centralized lubrication system of a heavy-duty ball mill gearbox. The lubrication system circulated approximately 1,500 L/min of ISO VG 46 gear oil. Because the gearbox depends on continuous oil circulation for lubrication and cooling, filtration performance had to be considered together with flow requirements. The Main Filtration Challenges 1. Heavy Dust Contamination Cement plants naturally generate significant amounts of dust. The Saudi project also operated in a desert environment, creating additional contamination challenge...
Industrial filtration systems do not always fit a standard equipment configuration. When the required housing material, filter bag size, connections or installation conditions are different, a custom bag filter housing may be a more practical option. What Can Be Customized? Several parts of an industrial bag filter housing can be configured according to project requirements. Housing Material Common choices include carbon steel, SS304, SS316 and SS316L. Material selection should consider the filtered fluid and operating conditions. Filter Bag Configuration The housing can be configured for single or multiple filter bags. Compatibility with #1, #2, #3 and #4 filter bags should be confirmed before fabrication. Connections and Flanges Inlet and outlet size, connection type, flange standard and connection position may need to match an existing pipeline. Pressure and Temperature Operating pressure and temperature should be confirmed when determining the appropriate housing configuration. Ins...
