Characterising the mix

  • Species mix by volume and the housing system, because these decide moisture more than the species itself.
  • Bedding and feed residues — sawdust, straw and spilled feed all change C/N and porosity.
  • Water content measured, not estimated: a 10-point moisture error changes the amendment volume by a third.
  • Contamination — baler twine, plastic wrap, stones and sand from yards.
  • Delivery pattern — daily removal or seasonal clean-out.

Manure compost production detail

Notes from our own records on animal manure compost production lines and the equipment involved.

As we all know, organic fertilizer becomes more and more popular, due to its strong function and obvious fertilizer efficiency. On the other hand, the raw material of organic fertilizer is usually organic waste, such as manure from livestock and poultry, livestock waste, sugar mil sludge and so on. Besides common composting ways, you can also adopt animal manure composting technology. And the final products, animal manure compost or animal dung, is a kind of high-quality organic fertilizer. The animal manure compost production include two parts, preliminary production and deep processing. And we will give you a detailed description below.

How to make animal manure compost? The animal manure composting technology utilize the combined effects of animals and microorganism to convert organic waste into useful components. There are many types of organic waste can be used as raw materials, such as cow dung, chicken manure, food waste, sewage, strew and so on. Before adding manure wastes, you should make the organic waste semi-decomposed. Because the temperature of compost pile may achieve 60℃ to 70℃ at the beginning of composting, which is too high to live for vaulable organic manure wastes contents.

How to conduct deep processing of animal manure compost with YUSHUNXIN equipment?

In order to further processing animal manure compost, you need conduct the following steps, mainly including crushing, granulating, screening and packaging process. Crushing process: Crushing the animal manure compost is prepared for granulation. Because granulating process need uniform fertilizer powder. In order to get powder, you can adopt YUSHUNXIN crushing machine to deal with potential fertilizer caking and make powder that meets the granulation standard. There are new type vertical crusher, semi-wet material crusher for you to choose. Granulating process: Granulation is the most important step for granular animal manure compost production. Granulating machine is necessary in this step, which can convert fertilizer powder into granular fertilizer by wet pelleting. The animal manure compost pellets are convenient for storage and application. Therefore, you can adopt YUSHUNXIN granulator to make granular fertilizer. Our machines for granulating fertilizer power include new type organic fertilizer granalator, rotary drum churning granulator and disc granulator.

Screening process: After granulation, you can apply screening machine to select out pellets with unqualified size so as to ensure the final quality. And the unqualified pellets will be sent back to crushing machine for secondary granulation. This process is mainly for obtaining uniform pellets.

Packaging process: After processing, uniform will be sent to packaging machine by conveying equipment, such as YUSHUNXIN screw conveyor and mobile belt conveyor. The packaging of animal manure compost is mainly for storage and transport in a convenient way. In this process, you can apply YUSHUNXIN single (double) bucket auomatic packing scale, which can automatically control quantity for each bag. What’s more, the weight of each bag is adjustable, which can meet your different requirements.

What’s the features and functions of animal manure compost? Animal manure compost is a kind of high-quality organic fertilizer. For one thing, the production of animal manure compost is a natural, ordourless and aerobic process, which is economically friendly. For the other thing, the abundant nutrients in vermiconpost can provide good growing environment. It is rich in nutrients. Besides macroelements and multiple microelements and 18 kinds of amino acids, the vermicompost respectively has 30% organic matter and humus. What’s more, there are some valuable antagonistic microbe and unknown auxin. Abundant organic matters: The standard for evaluating lands’ fertile degree is the content of organic matters. The organic matters content of animal manure compost is 30%, which can be absorbed by soil and plants easily.

Rich in microorganism groups: Animal dung organic fertilizer is rich in beneficial microorganism content, which will quickly inhibit the reproduction of harmful bacteria. Meanwhile, the metabolism of microorganisms can improve physical and chemical property of soil, so as to fertilize the soil. Rich in humid acid: The humid acid content of animal manure compost is 21% to 40%, which can improve soil structure and balance PH value. The vermicompost is available for various crops as base fertilizer or top dressing. In a word, YUSHUNXIN can provide you various machines for animal manure compost production and customized services. If you have demand on organic fertilizer making machines or other related problems, please contact us.

FAQ

Plant engineering questions

Can different animal manures be composted together?

Yes, and blending is often beneficial: poultry manure supplies nitrogen while cattle or horse manure supplies carbon and structure. The blend must be characterised for moisture and C/N as a mixture, not as separate streams.

How long does manure take to compost?

Four to six weeks turned in windrows, two to three weeks in aerated piles, and one to two weeks in a controlled vessel — plus two to four weeks of curing before the material becomes a stable product.

What is the biggest cause of failure in manure composting?

Moisture. Manure arriving wetter than the design assumed either goes anaerobic or requires far more amendment than budgeted. Measuring moisture on arrival, and designing the amendment system on the worst month, prevents most of it.
