Design, Development and Analysis of Roller Unit Assembly and Guide ring of Calcination Drum

Solid waste refers to reuse solid and semi solid waste matters except the night soil. As per Municipal solid waste Management and Handling rules -2000 , solid waste management is in the obligatory function of urban local bodies, but in actual practice the solid waste management is given the last priority and the duties are either not performed or poorly performed consequently the city has to face numerable problems related to environment and sanitation .The solid waste management approach in India is extremely inefficient, using old and obsolete system technology for storage collection processing, treatment and disposal. Hence by taking into ill effects due to improper disposal of wastes due to which the atmosphere becomes ugly and unhygienic; different methods for recycling are used. Composting is one of the methods which is the biological decomposition of biodegradable solid waste under controlled predominantly aerobic conditions to a state that is sufficiently stable for nuisance-free storage and handling and is satisfactorily matured for safe use in agriculture. In order to perform this process it is necessary that the wastes should be bifurcated into degradable and non degradable ones. This can be done by the specially designed equipment named Calcination Drum.
