Brief introduction of the process of producing livestock manure organic fertilizer by organic fertilizer granulation process, the organic fertilizer granulator of the fertilizer production process is drum granulator, so the fertilizer granulation process also is called drum granulation process:
The treated poultry manure (cattle manure, sheep manure, chicken manure, pig manure, duck manure, etc.) is directly transported to the raw material silo (or raw material agitator).
It is conveyed into the drum granulator, and at the same time, saturated steam (or water) is introduced, and the material forms a rolling material by the friction generated by the rotation of the drum granulator, and the pressing force generated by the rolling makes the liquid phase contain The material agglomerates into small particles that become the core and adhere to the surrounding powder to form acceptable particles.
It is transported to the organic fertilizer dryer for heat exchange with the heat from the hot blast stove.
The particles are sorted into the hot sieving, and the fine particles are directly returned to the drum granulator, and the core continues to participate in the adhesion of the particles into balls.
The screened semi-finished granules are transported to an organic fertilizer cooler to cool the fertilizer by natural cold air or strong cooling air.
The product is conveyed to the finished sifter, and the large particles are pulverized by the pulverizer and returned to the drum granulator to continue to participate in the ball formation.
The qualified products after screening are sent to the coating machine for coating treatment.
Transfer to the fully automatic packaging scale for weighing, packaging and storage.
Drying, cooling and workshop dust are emptied by a cyclone dust collector, labyrinth dust chamber and wet scrubbing.
The use of drum granulation to produce livestock manure organic fertilizer has the following advantages:
Steam is introduced into the material layer in the drum to increase the temperature of the granulated material, so that the salt of the granulated material is dissolved, and a high liquid phase is obtained at a low moisture content to satisfy the liquid phase required for granulation of the material. At the same time, the amount of evaporated water in the drying process is reduced.
The inner wall of the drum is lined with a plurality of soft rubber sheets or polypropylene sheets, and vent holes are opened at corresponding positions on the cylinder body. When the inner liner is turned from the bottom to the top at the same time, the inner lining is drooped due to its own weight, so that the lining adheres to The material on the lining falls due to gravity, which automatically cleans the material.
During operation, the operator can observe the material into the ball at any time, and take corresponding measures as needed to ensure the normal operation of the system. We are 20 years old plant of organic fertilizer production equipment, our organic fertilizer equipment model is complete, it is ex-factory price.
