Organic Fertilizer Production Line-----Taking 1000 cattle as example

In terms of most customers, they may do not have a clear definition on  the capacity of production line. Therefore, it is difficult for them to choose and purchase suitable equipment. Here, we will take 1000 cattle as an example to introduce the needed equipment and proper capacity.

Generally speaking, one cow produces 20 kg cow manure for each day. That is to say, 1000 cattle will produce 20 tons/per day in total. Therefore, you can choose production line with capacity of 2 tons/h. After you have a general plan in your mind, you can begin to choose equipment to organize complete production line.

There are 5 steps for you to produce granular cow dung fertilizer, and you may use different equipment in different steps.

  1. Composting: In this process, you need to guarantee the water content of cow manure is 50% to 60%. If there are too much water, you can adopt solid-liquid separator to decrease the water content. And then you can add some hay, saw dust, straw and bacteria to make compost. In addition, you need to turn the compost pile regularly after the temperature increase to 70 ℃. And we recommend windrow composting equipment to you for quick compost.
  2. Mixing: In this process, you can add some functional bacteria or other materials to increase the function of cow manure fertilizer. In order to blend them evenly, you can adopt Tongda disc mixer or horizontal mixer.

  3. Granulating: In this step, granulator will convert powdery organic fertilizer into granules under the principle of wet granulation. New type organic fertilizer granulator, pan/disc granulator and rotary drum churning granulator are available.
  4. Drying, cooling and screening: These three steps are coherent. Granular fertilizer made by granulator will be sent to drying and cooling system to decrease moisture. And then, the conveying system will send them to rotary screen machine. In this process, unqualified pellets will be selected out and sent back for secondary granulation. 

  5. Packaging: Different with unqualified pellets, pellets with qualified size will be sent for packaging. The cow manure fertilizer will be quantitatively weighed and bagged by automatic packing scale.

How does vermicomposting work?

Image
The vermicomposting procedure incorporates two distinct stages in regards to night crawler movement: (I) a functioning stage during which night crawlers process the natural substrate, in this manner altering its physical state and microbial creation, and (ii) a development stage set apart by the dislodging of the worms towards fresher layers of undigested substrate, during which the microorganisms assume control over the decay of the night crawler handled substrate. The length of the development stage isn't fixed, and relies upon the effectiveness with which the dynamic period of the procedure happens, which thusly is dictated by the species and thickness of worms , and the rate at which the buildup is connected. All the more explicitly, the effect of night crawlers on the deterioration of natural waste during the vermicomposting procedure is at first because of gut related procedures (GAPs), i.e., by means of the impacts of ingestion, absorption and osmosis of the natu...

How to Make Quality Compost?

Image
Fertilizing the soil starts when a heap of waste is made. Living beings quickly begin to devour the accessible oxygen and convert the materials into carbon dioxide, water vapor, and warmth. Fertilizing the soil is something other than heaping the material and giving it a chance to sit, be that as it may. Fertilizing the soil is the dynamic administration of excrement and bedding to help the deterioration of natural materials by microorganisms under controlled conditions. Successful fertilizing the soil is influenced by four main considerations: •  Aeration •  Nutrient parity •  Moisture content •  Temperature In the event that these four components are appropriately controlled, treating the soil will occur at an exceptionally fast pace. Air circulation  is the key component in proficient fertilizing the soil. Treating the soil is a vigorous procedure, implying that it requires heaps of oxygen. Air can be given by mixing...

How does cow manure become organic fertilizer by composting?

Image
Manure from cow  can be converted into organic fertilizer by composting. Generally talking there are two phases to the fertilizing the soil procedure. These two stages can not be seen independently from each other and happen all the while in various parts of the windrow. The main period of the procedure is known as the "hot spoiling", "sanitisation" or "disassembling" stage. Amid this stage the center of the windrow will ideally have a consistent temperature of 60-62 degrees Celcius. This temperature ought to be come to withing 48-72 hours of setting up the windrow and turning it for the first time by   cow manure composting equipment . After around 3 weeks a greater part of the accessible supplements have been eaten up by the microorganisms and transformed into less unstable mixes. Another military of microorganisms begins to wind up dynamic which fabricate since quite a while ago anchored mixes which append to the earth, transforming it into what we...
