Product characteristics of the roller extrusion granulator for earthworm manure organic fertilizer

 Earthworm manure organic fertilizer has an organic matter content of about 30%, and after two rounds of fermentation and animal digestion, the organic matter formed is of high quality, easily soluble in the soil, and easily absorbed by plants. Promote soil particle structure, improve soil permeability, water retention, fertility, and facilitate the reproduction and increase of microorganisms, enhance the ability of the soil to absorb and store nutrients, and solve the problems of frequent, large amounts, easy loss, and low utilization rate of chemical fertilizers from the source. The organic matter particles digested by earthworms are small, with a surface area increased by more than 100 times compared to before digestion, providing more opportunities for soil to come into contact with air, fundamentally solving the problem of soil compaction. According to research results from domestic research institutions, the effect of one kilogram of earthworm manure can be equivalent to 10 kilograms of farmyard manure, which is both economical and convenient to use.

Product characteristics of organic fertilizer roller extrusion granulator:

1. The material is forcibly compressed and formed by mechanical pressure, without adding any wetting agent, which does not damage the chemical properties of the material and does not reduce the effective content of the product. The purity of the product is guaranteed.

2. The process flow is brief, with low energy consumption, high output, automated production process, and cyclic operation, suitable for large-scale continuous production.

3. Dry powder is directly granulated without the need for subsequent drying processes, which is more conducive to the connection and transformation of existing production processes.

4. The particle strength is high, and the increase in bulk density is more significant than other granulation methods. Especially, the organic fertilizer roller extrusion granulator is suitable for increasing the stacking proportion of products, and the particle strength can be adjusted. By adjusting the pressure of the roller, the strength of the finished product can be controlled.

5. The size of the roller skin ball socket of the organic fertilizer roller extrusion granulator determines the size of the material diameter, usually 3-8mm.

6. Customizable organic fertilizer roller extrusion granulator roller skin can be obtained by changing the groove form of the roller surface to obtain materials in different shapes such as sheet, strip, and flat ball.
