In the past, animal manure was thought to be a valuable source of nutrients for plants, but it has now become a burden. Because of its handling and transportation costs a lot. At that time, the nutritional content of commercial fertilizer is more cost-effective than animal manure. To eliminate the pollution of animal feces to water, air and soil is a problem that people care about.
Cow dung is one of a byproduct of agricultural activities which has produced large quantities of animal wastes in the form of manures in many parts of the world in recent years .Although some of manure can be used as fertilizer, not all of the manure can be used in this way to consume, and excess is a kind of environmental responsibility.This has also resulted in waste of resources, so another possibility is that the use of feces as a direct or indirect source of fuel.
With the rapid development of dairy industry, dairy manure pollution has become a big problem. When summer comes, the smell is strong. In addition, the reproduction of all kinds of bacterial pathogens, seriously affect the population of health and environmental hygiene. At the same time, not fully fermented cow dung, will produce methane gas, causing air pollution. According to the relevant information, the environmental pollution of dairy cattle manure has been more than industrial pollution. Therefore, the dairy manure pellets are more and more popular, effectively solve the problem of environmental pollution in aquaculture, and achieved good social and economic benefits.
Cows eat a variety of leaves, grass, wheat straw, corn and so on, and thoroughly chew everything. Cow dung is 0.7 ~ 0.8 times the calorific value of coal, the calorific value of 1.3t pellets, cow dung is equivalent to 1t of the calorific value of coal calorific value. If the pill in support of burning furnace burning dung, cow dung particle combustion efficiency than coal combustion boiler combustion efficiency 1.3-1.5 times. So 1T pellets heat utilization rate is approximately equal to the cow dung 1t coal heat utilization rate.So their feces is a lot of combustible fiber, so cow manure into pellets to burn.
In a word,cow manure pellets made by pellet making machine are increasingly used as a fuel for the use and promotion, which not only promote the development of animal husbandry, but also to protect the environment. So it can get better social benefit and economic benefit.
