What are the requirements for filters used in a cement plant?
In raw mill/kiln system/clinker cooler especially for reverse air bag house (RABH) fibre glass with silicon, graphite and teflon (SGT) finish bags are required. If acidic fumes are higher due to impure coal etc. same fabric with PTFE membrane lamination is to be used for better life. For cement grinding acrylic/mixed felt as well as polyester non-woven needle felt with/without water repellent bags are to be used.
What are the product trends?
With regard to process filter the latest technological / product trend is to use fiber glass bags as well as hybrid (combo of polymide P84, fibre glass and PTFE). How process optimisation helps in reduction of environmental impact? The process optimisation definitely helps in reduction of environmental impact; say if we use appropriate fabric with high filtration efficiency will give low stake emission (even less than the government norms).
What is the scope of hybrid filters in the Indian cement industry?
In cement industry, use of hybrid filters is increasing fast. The hybrid filters are costlier than the existing but if you calculate the payback period then there are advantages like longer life and higher efficiency.
