The granulation process and advantages of the cow and sheep manure stirring tooth granulator

 The specialized granulation equipment for organic and compound fertilizers utilizes the high-speed rotating mechanical stirring force and the resulting aerodynamic force to continuously mix, granulate, spheroidize, extrude, collide, compact, and polish fine powder materials in the machine, achieving pure organic granulation. No adhesive is added during granulation, and the moisture content of the raw materials can be around 20-40%, thus achieving the purpose of granulation.

The rotating stirring tooth granulator for cow and sheep manure cylinder is a molding machine that can manufacture materials into specific shapes. The drum granulator is one of the key equipment in the compound fertilizer industry, suitable for cold and hot granulation as well as large-scale production of high, medium and low concentration compound fertilizers. The main working method is wet granulation of pellets. By using a certain amount of water or steam, the basic fertilizer is humidified in the cylinder and undergoes a thorough chemical reaction. Under certain liquid phase conditions, with the help of the rotational motion of the cylinder, the material particles are squeezed and agglomerated into balls.

The rotating stirring teeth granulator for cow and sheep manure cylinder adopts a special rubber plate lining or acid resistant stainless steel lining plate, achieving automatic scar removal and tumor removal, and eliminating the traditional scraper device. This machine has the characteristics of high ball forming strength, good appearance quality, corrosion resistance, wear resistance, low energy consumption, long service life, and convenient operation and maintenance. Performance parameters: Rotary drum granulator, which is equipped with steam, gas ammonia, or phosphoric acid or nitrogen solution, phosphoric acid ammonia slurry, and heavy calcium slurry, to complete the chemical reaction and heating process of compound fertilizer granulation in the cylinder; Alternatively, in the cold granulation process of adding a small amount of water to the compound fertilizer, the materials that need to be granulated are rotated through the cylinder, causing rolling rotation when there is no material in the cylinder, and then agglomerated into balls at a certain humidity and temperature to complete the granulation process.

The particle shape of the specialized granulation equipment for organic and compound fertilizers is spherical, with a particle size standard generally between 3-6mm and a granulation rate of ≥ 90%. The size of the particle diameter can be adjusted appropriately by the material mixing amount and the spindle speed. Generally, the lower the mixing amount, the higher the rotation speed, and the smaller the particles. The finer the basic particles of the material, the higher the sphericity of the particles, the better the ball forming quality, and the stronger the particles. After granulation, they can be sieved, reducing drying energy consumption. (Suitable raw materials for processing organic fertilizers include animal manure, waste residue, edible mushroom residue, sludge, crop straw, crude fiber, organic waste, etc.)

  There is a huge demand for bio organic fertilizers in China, especially for some economically efficient and high-quality bio organic fertilizers, which are more popular among farmers. Therefore, opening an organic fertilizer equipment processing fertilizer factory can yield substantial returns. Organic fertilizer trading market. The production of green fruits and vegetables cannot be separated from organic fertilizers. A large amount of organic fertilizer is piled up and wasted in urban areas, and there is a huge demand gap for organic fertilizer in rural areas. If a rural organic fertilizer trading market is established, a bridge between supply and demand can be established, and the production of organic fertilizer through processing of bio   organic fertilizer equipment   can turn waste into treasure. How much does the entire set of equipment for processing bio organic fertilizers cost? 1. Determine the size of  organic fertilizer equipment , such as the annual p...

Main production process guidance of organic fertilizer production equipment

Image
  Organic fertilizer is a natural fertilizer, but also an important part of sustainable development of human agriculture, so people pay more and more attention to the production of organic fertilizer. The following introduces the main production process of  organic fertilizer production equipment  and the relevant situation of organic fertilizer fermentation equipment. Organic fertilizer production process is generally divided into: fermentation, crushing, ingredients, mixing, molding, drying, cooling, screening, packaging. Of course, some high-end fertilizers will add slurry to make the fertilizer look more beautiful. 1. The first is the fermentation equipment. Most organic fertilizer manufacturers will use the composting fermentation. The key point of composting fermentation is the strain. Only when there are good strains can we get high-quality organic fertilizer. Then there is the crushing equipment. The more commonly used crushing equipment in the organic fertilizer ...
