The granulation process of a complete set of earthworm manure organic fertilizer processing equipment

 The humic acid in earthworm manure is different from that in general organic fertilizers because earthworms regularly digest and mix many organic nutrients to transform them into water-soluble substances, which are easily absorbed by plants. Planting crops with earthworm manure not only has the effects of drought resistance and fertilizer retention, promoting roots and seedlings, and not reducing production, but also significantly improves the quality of crops and restores their natural flavor. It can also be used as an additive for poultry and livestock feed, making it convenient, clean, and safe to use.

The complete set of earthworm manure organic fertilizer processing equipment pre-treatment: After the compost raw materials are transported to the yard, weighed by a scale, sent to a mixing and stirring device, mixed with organic wastewater from production and domestic use in the factory, added with composite bacteria, and roughly adjusted the moisture and carbon nitrogen ratio of the compost according to the raw material composition. After mixing, they enter the next process.

The complete set of earthworm manure organic fertilizer processing equipment undergoes one-time fermentation: the mixed raw materials are fed into a fermentation tank using a loader and stacked into a fermentation pile. A fan is used to forcibly ventilate from the bottom of the fermentation tank upwards for oxygen supply. At the same time, the pile is turned over for about 2 days and supplemented with water (mainly organic wastewater from production and domestic use) and nutrients. The fermentation temperature is controlled between 500C and 650C for aerobic fermentation. The one-time fermentation cycle of this project is 8 days, Every day, one pool of raw materials is fed out and one pool of semi-finished products is produced. After the fermented semi-finished products are discharged, they are ready to enter the next process.

Complete set of earthworm manure organic fertilizer processing equipment for post-processing: Further screening of the compost product, and treatment of the screened material according to the moisture content. After sieving and granulating, the material is sent to a dryer heated by biogas in the biogas digester for drying. After adding medium and trace elements in proportion, it is stirred and mixed to make a finished product, which is then packaged and stored for sale. The screened material is returned to the crushing process for reuse.

Three forms of granulation for processing fertilizers in compound fertilizer production lines

图片
  In the  drum granulator , steam, ammonia gas or phosphoric acid or nitrogen solution, phosphorus ammonia slurry, and barite slurry are introduced into the drum to complete the granulation process of chemical reaction and heat supply in the cylinder; or the cold granulation process of compound fertilizer with a small amount of water is added. The materials to be granulated are rolled and rotated in the cylinder, and agglomerate into balls under certain humidity and temperature, Complete the ball making process. NPK fertilizer granulator  of compound fertilizer is produced by non drying process at room temperature, with one-time molding and output of 1-4t / h. Complete set of equipment process layout compact, scientific and reasonable, advanced technology. Energy saving and consumption reduction, no three wastes discharge, stable operation, reliable operation and convenient maintenance. It is suitable for granulation of compound fertilizer, medicine, chemical industry, fe...

  Raw materials for preparing granular potash fertilizer by  drum granulator Powdered potassium chloride (0-0-60) or powdered potassium sulfate (0-0-50); binder, including magnesium chloride, magnesium sulfate, magnesium oxide, bitter earth powder; filler, including clay, bentonite, gypsum, etc. Production process of potassium fertilizer granules by drum granulator 1. Water and magnesium chloride (or magnesium sulfate) are added in the reactor according to the proportion, and the solution is formed by stirring and dissolving. Then, powdered magnesium oxide is added according to a certain proportion, and further stirred evenly to form the required magnesium oxychloride hydrate (or magnesium oxysulfide hydrate). 2. The powdered potassium chloride or potassium sulfate is added into the drum  npk fertilizer granulator , and the granulation additive magnesium oxychloride hydrate (or magnesium oxysulfide hydrate) with the mass fraction of 0.5% - 10.0% on dry basis is sprayed in...

How does an organic fertilizer composter produce organic fertilizer from chicken manure?

图片
  Chicken manure  organic fertilizer manufacturing process , the raw materials used include: dry chicken manure 45-50%, fermentation bacteria, cake fertilizer, mud fertilizer, sterilization and deodorant. Biological fermentation and ordinary fermentation are used to produce chicken manure bio-organic fertilizer. The product obtained by the organic fertilizer manufacturing process is a kind of chicken manure bio-organic fertilizer. After application, it can greatly increase the production of food, economy, vegetables, fruits and other crops, improve the quality of agricultural products, and improve crop properties. Environmentally safe and non-toxic, it is a new type of environmentally friendly fertilizer. The characteristics of chicken manure organic fertilizer are as follows: 1、 Chicken manure contains a lot of organic matter because of its short digestive tract. Chicken manure is used as organic fertilizer, which has good fertilizer utilization rate and high nutritional valu...
