Anticorrosion technology of organic fertilizer production machine 1. Electrostatic powder spraying. The application of traditional coatings and coatings in the production of organic fertilizer production equipment is liquid, which contains a lot of esters, ketones, hydrocarbons and other solvents, bringing a series of problems to the production, storage, transportation and construction. ...
The main characteristics of NPK fertilizer production by counter roll pelletizing equipment are as follows: Processing compound fertilizer containing a certain proportion of nitrate nitrogen. Nitrate nitrogen is widely used due to its high temperature and humidity, but it has strong hygroscopicity, and it will be deliquescence into mud under high temperature and humidity, which makes the ...
Wet organic fertilizer granulator is designed and manufactured by a new process of wet continuous push rod granulation. This organic fertilizer granulation machine can not only granulate a variety of organic matters, especially for coarse fiber materials which are difficult to be granulated by conventional equipment, such as crop straw, wine residue, fungus residue, medicine residue, animal ...
Cow dung organic fertilizer production line is a complete set of equipment for processing organic fertilizer with cow dung as raw material. After dehydration by organic fertilizer equipment, the moisture content is about 40%. Crops such as straw and rice bran (containing N, P, K) can also be used as filling materials, and then biological bacteria agent is sprinkled on it. 1kg bacteria agent is ...
1. The double roller granulator does not need to heat and humidify the material, which not only saves investment, but also saves energy. It can also adapt to the granulation of heat sensitive materials, such as ammonium bicarbonate and some organic fertilizers. 2. There is no waste water or waste gas discharged in the production process, which will not pollute the environment. 3. The process ...
Usually, the feeding device is located above the side-by-side rolls, and the material is forced into the roll gap between the two rolls by the friction between the material in the feeding system and the rolls. Under the rotation of the roller, the material is brought in and squeezed into pancake (sheet) shape. ...
In the organic fertilizer production line, chicken manure is mixed with appropriate amount of straw powder. The amount of mixing depends on the water content of chicken manure. Generally, 45% water content is required for fermentation. It is appropriate to knead chicken manure into a ball by hand. Water can be seen between fingers, but no water dripping, and it is suitable to disperse when the ...
Organic fertilizer production machine is not a single piece, but a set of series, a complete set of processing machinery and equipment contains a number of machines and equipment. The small and simple organic fertilizer production line includes: feeding, conveying, crushing, fermentation flip / dump, screening and packaging processes; The medium-sized and large-scale complex organic fertilizer ...
There are many factors influencing the process of composting organic waste. This paper provides an experimental and theoretical evaluation of the leaf composting process to elucidate the importance of these various factors during composting of leaves. The analysis is performed specifically for the environmental conditions encountered in cold climates. Theoretical models are developed to evaluate ...
The two principal biological treatment methods available are aerobe treatment (composting) and anaerobe treatment (digestion/fermentation). In Norway so far, aerobe treatment has been the most popular solution. Both windrow composting and tunnel composting systems are in use. The first anaerobe treatment plant of ...
