Can chicken manure compost be pelletized?

With the rapid development of modern animal husbandry, chicken manure processing has become the focus of the industry. Composting and pelletizing chicken manure not only effectively solves the problem of chicken manure pollution, but also produces high-quality organic fertilizers and carries out secondary recycling of resources. Today, let’s learn more about the green agricultural practice of composting and pelletizing chicken manure by Fude Machinery.

Chicken manure compost pelletization method

  • Disk Granularity Method

The disc pelletizer is a wide range of equipment used to pelletize chicken manure compost, which works by feeding fermented and decomposed chicken manure into a rotating disc rotating at a constant speed, driven by an engine. The material is continuously rolled and gathered in the disk by centrifugal force, friction and gravity and gradually formed into particles by spraying binder. The size and shape of the particles can be controlled by adjusting these parameters, the rotational speed and the inclination of the disk, as well as the speed of material transportation. The disk mill granulation method offers the following advantages, as the balls are formed quickly, round particles and good strength, and are suitable for mass production.

  • Extrusion pelletizing method

The extruder pelletizer adopts the principle of roller extrusion or thread extrusion to pelletize, take double roller extrusion as an example, and then the chicken manure is placed between two parallel rollers with mold cavities. When the drums rotate, the material is pressed under pressure into the die cavity to form particles with a certain shape. The particles, prepared by the extrusion pelletizing method, have high strength and correct shape, however, the investment in equipment is relatively large, and the requirements for the particle size and humidity of the material are more stringent.

  • Granular Rounding Method

The annular throwing round pelletizer utilizes a high-speed rotating annular disc to throw the chicken manure upward, forming round particles under the effect of centrifugal force and friction, obtained by this method, has a round shape and smooth surface, suitable for when there are high requirements on the appearance of the particles, and, at the same time, the energy consumption of the equipment is relatively large when it is in operation.

Chicken manure compost granulation process

  • Transportation of raw material:The fermented and decomposed compost from the chicken manure is transported via belt conveyor to the loading holes of the pelletizer, screw conveyor and other equipment.
  • Pelletizing:The material is converted into pellets using appropriate pelletizing equipment according to the selected pelletizing method.
  • Screening: The granular material is passed through a vibrating screen to select the appropriate size granules. Unsuitable large granules and fine powders are returned to the pelletizer for disposal through a recycling system.
  • Drying:If the moisture content of the granules is high, they are dried in a dryer to ensure that the moisture content of the granules meets the requirements for storage and use, usually below 10%.
  • Cooling: The dried pellets have a relatively high temperature, so they are cooled by means of a cooler to prevent them from aggregating due to high temperatures during storage.
  • Packaging:The cooled pellets, meeting the requirements, are weighed and packaged for storage and sale.

Chicken manure compost pelletizing equipment selection

  • Production scale:Small farms or farmers can choose lower productivity, simple structure of the granulation equipment. For example, small disc granulator; large-scale organic fertilizer producers should choose a large output of equipment with a high degree of automation to meet the needs of large-scale production.
  • Product quality requirements:If you have high requirements for the shape, strength, particle appearance, etc., you need to choose the right granulation equipment according to the specific needs, for example: circular granulator may be more suitable for the production of high-quality organic fertilizers; for the production of Pu province
  • The requirements for agricultural organic fertilizer can be disc granulator or extruder.
  • Equipment performance and price: Compare pelletizing equipment produced by different manufacturers, study equipment quality, stability, energy consumption and other productivity indicators, and compare equipment costs to choose cost-effective products. In addition, the after-sales service of the equipment should also be considered to ensure timely maintenance and technical support in case of equipment failure.
Organic Fertilizer Pellets

Chicken manure composting and granulation is an important way to realize the efficient use of chicken manure resources, which not only solves the problem of aquaculture waste recycling, but also provides high-quality organic fertilizer for agricultural production. With the continuous development of technology and the improvement of people’s environmental awareness, composting chicken manure granulation technology, no doubt, will play an increasingly important role in the development of green agriculture.
