The drum granulator is a commonly used fertilizer production machine . In the steam granulation process, the pellets are mainly clad, so the material circulation volume should be larger, so this can provide a larger coating process Nuclear, and the water injection volume should be smaller, so that the water absorption of the core can be reduced. When pelletizing by bonding or "gathering", the moisture content of the material is smaller, because at this time, the material in the rotary drum is mainly composed of fresh materials with small particle size and mutual bonding. The liquid ratio required for bonding should be large, because the space between the fine powder particles to be bonded with each other should be filled with water. The main structure of the rotary drum granulator is an inclined rotary cylinder, the drive can be constant speed or variable speed. When the liquid content of the feed powder is appropriate, agglomeration occurs and rolls in the drum. The drum ...

Sulfur coating technology is a kind of microcrystalline polymer material with sulfur and paraffin as main raw materials on the basis of large granule urea, so as to achieve slow controlled release of nitrogen nutrients. Sulfur coated urea should meet the following three indicators: 1. The content of N was 31 / 34 / 35 / 37. 2. Under the condition of 38 ℃ still water and constant temperature, 10%, 15%, 20% and 25% of total nitrogen content were released in 24 hours. 3. 60% - 70% of total nitrogen was released in seven days. The key technology of sulfur coated urea coating can be used in NPK fertilizer granulation, drum granulation and other slow and controlled-release fertilizers, realize curtain coating granulation of various solid granular fertilizers, and produce various slow and controlled-release fertilizers such as super granular urea, sulfur coated compound fertilizer, lignosulfonate urea, humic acid urea and water-soluble resin. The coated controlled-release fertilizer ...

In the NPK fertilizer manufacturing process , a coating process is added to make a slow-release fertilizer. Slow-release fertilizer is also called controlled-release fertilizer. The release rate of nutrients in fertilizers can be controlled to a certain extent for continuous absorption and utilization by crops. After the fertilizer is coated, it can reduce the loss of fertilizer nutrients, especially nitrogen, in the soil. Can reduce the frequency of fertilization, save labor and cost. To increase crop yield and income, the application of slow-release fertilizer can improve crop resistance to disease and lodging. The amount of coating agent is controlled according to the length of particle preservation in NPK fertilizer manufacturing process. So what are the precautions about the coating of NPK fertilizer granulation? Fertilizer granule coating machine is composed of screw conveyor, mixing tank, oil pump, main machine, etc. It can effectively prevent the caking of organic fertilize...

Fertilizer equipment plays an important role in the production of organic fertilizer. The daily maintenance of fertilizer manufacturing equipment is also very important. Otherwise, it will be damaged suddenly and delay the work. At the same time, it is not conducive to the maintenance and maintenance of the machine itself and reduce the service life. Therefore, we should pay special attention to the use of organic fertilizer equipment to ensure the smooth operation of fertilizer manufacturing equipment. The following describes the equipments required for biofertilizer production , as well as safe operation precautions. 1. It is easy for the newly installed organic fertilizer equipment to loosen the tyre, which must be checked frequently to see whether the machine works normally. 2. Pay attention to check the wear degree of the easily worn parts, replace the worn parts at any time, and place the underframe plane of the moving device. Dust and other things should be removed first to...
