The grinder is a type of equipment used in RDF (Refuse Derived Fuel) plants to break down solid waste into smaller particles. RDF plants typically receive a mix of various types of waste, including municipal solid waste (MSW), commercial waste, and industrial waste, which are sorted, processed, and converted into a fuel that can be used to generate energy.
Grinders are essential in RDF plants as they reduce the size of the waste to a uniform particle size, making it easier to handle and process further. The grinding process also helps to remove contaminants such as metal, glass, and stones from the waste stream.
There are various types of grinders used in RDF plants, including hammer mills, impact mills, and shear shredders. Hammer mills use rotating hammers to break down the waste, while impact mills use rotating blades to cut the waste. Shear shredders use a combination of cutting and tearing actions to break down the waste.
Grinders play an important role in RDF plants, as they help to improve the efficiency of the waste-to-energy process, reduce the volume of waste, and minimize the environmental impact of waste disposal.
