Compost grinder machine applied in compost processing at Qatar
Composting is the purposeful biodegradation of organic matter, such as yard and food waste. The decomposition is performed by micro‐organisms, mostly bacteria, but also yeasts and fungi.
Compost is a combination of food waste and brown waste that is being decomposed through aerobic decomposition into a rich black soil. The process of composting is simple and practiced by individuals in their homes, farmers on their land, and industrially by cities.
Compost soil is very rich soil and used for many purposes. A few of the places that it is used are in gardens, landscaping, horticulture, and agriculture. The compost soil itself is benefi‐cial for the land in many ways, including as a soil conditioner, a fertilizer to add vital humus or humic acids, and as a natural pesticide for soil. In ecosystems, compost soil is useful for erosion control, land and stream reclamation, wetland construction, and as landfill cover.
Price of machinery reflects capacity and maintenance requirements. Cheaper machines generally have lower processing capacities and higher maintenance requirements, as they may not have features that allow them to manage some contaminants. Size reduction machinery types include compost hammer mills grinders machine and shredders/chippers. Each has its advantages and disadvantages depending upon situation, feedstock and end-product type. These machines may be mobile (trailer-mounted and towed behind a truck) or fixed. The following summarises some of these features.
Grinders smash and crush large pieces of wood into smaller pieces, relying on a screen or grate to control the maximum particle size of the size-reduced material. These machines (appropriately sized) are capable of grinding a range of materials including pallets, railway sleepers and composite wood products. Stationary grinders can process between 10 and 50 tonnes of material per hour, depending upon the size of machinery used, screen size, type of material processed and moisture content. As these machinery types are usually gravity fed (top -loading), some types of materials (in particular those of low density), may not move through a grinder efficiently. As material is fed into the top of a grinder, it may, in some instances, be expelled from the grinder, creating additional safety hazards for operators and workers in the vicinity of the machinery. Also, due to their relatively short feed openings, long pieces of wood cannot be processed easily. Size-reduced material produced by tub grinders may be of variable sizes. This range in size may be a problem if uniformity of particle size is a requirement of an end-product .
Alternatives to gravity fed grinders include horizontal feed grinders. These machines address the previously mentioned safety issues, as material is fed into enclosed compartments. In addition, their horizontal layout allows these grinders to accept longer pieces of wood than do vertical feed grinders.
