Cow dung

Cow dung is a waste produced by many cattle farms. A large dairy farm may produce tens of tons of cow dung a day. If it is not treated in time, it may pollute our environment and water sources. After analyzing cow manure, it is found that it is rich in minerals and nutrients, and the organic content is higher than chicken manure. This is why many people make cow manure into fertilizer pellets. Studies have found that cow dung is the best choice for pelleting. Cow dung can not only be made into fertilizer pellets, but also into fuel pellets. This is because cows eat a variety of foods, such as grass, leaves, grains, wheat straw, etc., and chew the food thoroughly. Therefore, cow dung is composed of many combustible fibers, and it is also a good choice to make fuel pellets.

Working Principle

1. Cow dung drying: different from making other biomass fuel pellets, the first step for making cow manure fuel pellets would be drying. Because there is too much water contained in the cow manure. If crush the cow manure first, the too wet manure may probably block the crushing machine. After drying, the moisture of mature is decreased to below 15%.

2. Manure crushing: after drying, the manure will become loose and can be processed by the crushing machine. The crushing machine will pulverize the cow dung into powder with the diameter of 2-5mm.

3. Manure pelletizing: when the manure powder is fed into the manure pellet machine, it will be pressed by the great pressure inside the pellet machine. Then manure fuel pellets are made. Ring die pellet mill and flat die pellet mill are available for your selection. Whether to choose the small one or large one depends on your own needs.

4. Pellets cooling: cow dung fuel pellets discharged from the pellet mill are high in temperature and moisture content, then goes the cooling step. After that, the pellets can be burned in the boiler, or used as fertilizer in soil. The pellets can also be sieved when cooling, so that poor quality pellets and powder materials will be collected and reproduced.

5. Pellets packaging: once the cow dung fuel pellets are formed and cooled, they can be packaged in bags or stored in bulk.

Compared with other fuels, cow dung is cheaper than propane, most natural gas and electricity. In addition, it is also very effective. Where wood is very scarce, cow dung can be used as a substitute and used to reduce wood consumption pressure. In addition, cow dung requires a short collection time and is easy to obtain. Cow dung contains a reasonable amount of energy and can be used as a sustainable and renewable fuel source. It can also reduce the disposal costs of odors and other nuisances associated with large-scale farms.

Feasibility of Cow Dung Fuel Pellets

Because of the many disadvantages of directly using cow dung as fuel, cow dung fuel pellets seem to be a better choice. After pelletizing, the volume of cow dung fuel pellets is three times smaller than the original volume, but the burning time will be extended by three to four times. During the combustion process, no obvious dust or ash is discharged, and the density of the discharged ash is much lower, which can meet environmental protection standards.

Features of cow dung fuel pellets

1.Wide application. Cow dung fuel pellets can replace coal to be used to supply heat or as fuel. It is especially suitables for densely inhabited district.

2.It has no season limitation and can be used all the year round.

3.Making cow dung fuel pellets can reach conversion and appreciation of waste material.

4.Environmental friendly. As one green energy, sulphur content, ash content and nitrogen content of cow dung fuel pellets is much lower than coal, fossil oil, etc.

5.Low cost and high additional value. With locally abundant cow dung and cow dung pellets production line, you can make cow dung fuel pellets.

6.Big density and convenient to store. Cow dung fuel pellets has small volume and high density which makes it convenient to convert, store, transport and use.
