The working principle and granulation advantages of the roller extrusion granulator

 The roller squeezing granulator is powered by an electric motor to connect the belt, driving two roller molds to rotate in opposite directions. There are evenly distributed semi-circular grooves on the mold, and the mold rotates to the contact point to form a circle. The particle size caused is determined by the selected grinding tool and formed in one go. Suitable for organic fertilizers, compound fertilizers, feed, chemical and other fields.

The roller extrusion granulator belongs to the extrusion sliding model, and its working principle is driven by an electric motor to drive the belt and pulley, which are transmitted to the driving shaft through a reducer, and synchronized with the passive shaft through an open gear, working in opposite directions. The material of the roller extrusion granulator is added from the feeding hopper, formed by roller extrusion, demolded and pelletized, and then transported to the crushing screen studio through a pair of chains. The finished particles (balls) are screened and separated, and then the returned material is mixed with new material before pelletizing.

The roller extrusion granulator has the following advantages: 1. Circular operation, achieving continuous production and high yield of finished products; 2. The material is mechanically compressed and formed without any additives, ensuring the purity of the product. 3. The particle strength can be adjusted, and the finished product strength can be controlled by adjusting the pressure of the drum; 4. The extrusion granulator is suitable for various raw materials, and the particle strength can be freely adjusted according to different materials. 5. Compact structure, easy maintenance, simple operation, short process flow, low energy consumption, high efficiency, and low failure rate.

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...
