Separation Technology 4G th Generation |Secondary Separation 4G G Ultracut Classifier high performance classifier from Reject cone (TM) The 4G G classifier is equipped with the static and dynamic vane technology similar to the 3rd gen Classifier. Blades are aero dynamically designed for lower resistance and therefore lower power and lower wear. 4G th Generation Classifier:(added secondary classification) Secondary Separation from the Reject Cone by measured circulating air and separation device in the

Building Smarter Manufacturing With the Internet of Things (IoT) Advantages: Better than PLC and PC based controller & management system as these are largely disconnected from IT and Operational system IoT would resolve the wiring issues by 80%. We have experts with more than 10 years of experience in handling and developing IoT. ALTERNATIVE FUEL (Utilization of MSW (Municipal Solid Waste) in Cement Plant) INTRODUCTION Cement production is the second most energy

consuming large scale industrial process. Cement industry is an essential key factor in the waste management system for a safe and environmental friendly recycling of waste derived materials. No negative influence on the properties of the cement and its application occurs. WASTE MATERIAL HANDLING Waste material incineration Effective method to cater to waste and for power generation. Incineration is expensive to the public as its having maximum number of unit operations. Incineration plant should be replaced by recycling concept. Its impossible to reduce the emission of gases( Dioxine, Furans and SOx, NOx) and residue ( Ash disposal, heavy metals) Co-processing in cement plant Cost Efficient for the public Environmental friendly solution with almost no emission of heavy metals, dioxine, furans, SOx, and NOx. No influence on product(Clinker). Saving of imported fossile fuel and reduction of CO2 emissions. COMPARISON OF WASTE PROCESSING IN CEMENT

PRODUCTION AND WASTE INCINERATION Waste coprocessing in cement plant Waste processing in the incineration plant Saving of primary fuels (Coal, Gas, Oil) 100 % substitution of primary fuel according to the calorific value of the waste addition of primary fuel (oil or gas) necessary for ignition and complete combustion of the waste An organical compounds of waste (ashes) Ashes are completely recycled into the product clinker and cement Ashes have to be processed or in most cases deposed in landfills Heavy metal content of waste and related emissions Due to the alkalinity of the process complete immobilization of heavy metals in the crystal structure of clinker (Except Mercury) Heavy metals will be mainly evaporated and extremely expensive and complicated

filtering and washing systems have to be installed. Formation of dioxins and fuarans by chlorine and flourine compounds in the waste Combustion at 1450 c with Complete cracking of all Oranical compounds into the base molecule methane. Time window of denovosynthesis of dioxine neglectable. combustion at appr. 850 c with high retention time for complete combustion. time window for denovosynthsis of dioxins and furans high. after burning of waste gas sometimes necessary. Transportation of Waste Cement plants are located at the source of limestone. Transportation is necessary waste incineration plants are installed at the source of the waste. CLASSIFICATION OF WASTE DERIVED MATERIAL Waste Derived Material Non Re-generatable material Industrial Waste Solid - Electrical Waste

- Waste plastic - Crating material - Tire/Tire chips Liquid - Used lubricants - Photo chemical waste Municipal waste Solid - Plastic waste - Sewage sludge - Food rests Re-generatable material Agricultural Waste Solid - Wood chips - Saw dust - Agricultural husks - Raps oil resins - Animal and bone meal Liquid - Sun flower oil rests - Raps oil Gaseous - Bio gas - Composition gas FLOW SHEET- PREPARATION OF MSW COPROCESSING OF RDF IN CLINKER MANUFACTURING PROCESS SCOPE OF BQB (In association with Leading European companies)

Techno-commercial feasibility study the current operation philosophy and assessing the bottlenecks. Cooperating with local waste management systems, industrial and communities Design and installation of Preparation, Handling, Dosing and Feeding technology Suggestion to improve the combustion in calciner. Suggestion to control the emissions like heavy metals, Dioxine furans, SOx, NOx and CO2. Our Associates EURO KILNS ALL KIND OF KILN MECH. WORKS THANK YOU
