In the production work of the organic fertilizer pellet making machine, various failures will occur, which is a normal phenomenon. There are many reasons for the failure, some are caused by long-term use and aging, and some are caused by human operation errors, but no matter what kind of failure occurs, it is caused by improper daily maintenance.
If you make mistakes, there will not be so many failures and problems. Therefore, we need to review, but also need to seriously treat all kinds of failures of the organic fertilizer pellet making machine, and we need to seriously find the reasons and take measures to solve and deal with them.
A drum organic fertilizer pellet is a molding machine that can make materials into specific shapes. Rotary drum fertilizer pelletizer machine is one of the key equipments in the compound fertilizer industry. It is suitable for cold and hot granulation and large-scale production of high, medium and low concentration compound fertilizers.
The main working method is wet granulation of agglomerates. Through a certain amount of water or steam, the basic fertilizer is fully chemically reacted in the cylinder after humidity adjustment. Produce extrusion force to agglomerate into balls.
1. Process flow of compound fertilizer
The technological organic fertilizer pellet making machine process of compound fertilizer can be divided into: raw material batching, raw material stirring, raw material granulation, particle drying, particle cooling, particle classification, finished product coating, and finished product packaging.
(1) Raw materials:
Raw materials such as urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, heavy calcium, common calcium), potassium chloride (potassium sulfate) are allocated in proportion (according to market demand and local soil testing result).
(2) Stirring of raw materials:
Stir the prepared raw materials evenly to improve the overall uniform fertilizer content of the fertilizer granules.
(3) Raw material granulation:
The evenly stirred raw materials are sent to the organic fertilizer pellet making machine for granulation (can be granulated by turning stock, or by extrusion granulation).
(4) Particle drying:
The granules made by the organic fertilizer pellet making machine are sent to the dryer to dry the moisture contained in the granules to increase the strength of the granules and facilitate storage.
(5) Particle cooling:
The temperature of the dried fertilizer granules is too high, and it is easy to agglomerate. After cooling, it is convenient for bagging, storage and transportation.
(6) Grading of particles:
The cooled particles are classified, the unqualified particles are crushed and re-granulated, and the qualified products are screened out.
(7) Finished coating:
Coating the qualified products to increase the brightness and roundness of the particles.
(8) Finished product packaging:
Store the processed pellets, that is, the finished product, in a ventilated place.
2. Features of compound organic fertilizer machine technology
(1) The applicability of raw materials and its wide range: It is suitable for the processing of crude fiber organic wastes with a moisture content of about 30%, such as fermented livestock and poultry manure, sugar mill filter mud, urban sludge, paper sludge, distiller’s grains, straw, peat and so on. Direct granulation by organic fertilizer pellet making machine can produce pure organic fertilizer, organic inorganic fertilizer and bio-organic fertilizer with spherical particles.
(2) High spheroidization rate and high survival rate of biological bacteria: The new technology can make the spheroidization rate reach more than 90-95%, and the new technology of low temperature and large air volume drying can make the survival rate of microbial bacteria reach more than 90%.
(3) The organic fertilizer pellet making machine process flow is short and the operating cost is low. The organic raw materials used in this process do not need pre-treatment such as drying and crushing. The process flow is short and the operating cost is low. Organic raw materials with a moisture content of about 30% should be dried to less than 13%, pulverized to more than 80 mesh, and the amount of organic materials added should not be greater than 30%).
3. Advantages of RICHI compound fertilizer production line:
- The organic fertilizer pellet making machine has low investment, quick returns and good economic benefits.
- The complete set of organic fertilizer pellet making machine is compact in layout, scientific and reasonable, and advanced in technology.
- Energy saving and consumption reduction, no discharge of three wastes, stable operation, reliable operation and convenient maintenance.
- The raw material has wide adaptability and is suitable for granulation of various raw materials such as compound fertilizer, medicine, chemical industry, feed, etc. The product has a high granulation rate.
- It can produce various concentrations and various types of compound fertilizers (including organic fertilizers, inorganic fertilizers, biological fertilizers, magnetic fertilizers, etc.). Especially the granulation of rare earth, potash fertilizer and ammonium bicarbonate series compound fertilizer fills the domestic gap and ranks at the forefront of the country.
4. Key equipment – organic fertilizer pellet making machine
(1) Introduction of organic fertilizer making machine:
The main working mode of the rotary drum organic fertilizer pellet making machine is wet granulation of granules. Some water or steam or gas ammonia or nitrogen solution is passed in the machine to make the basic fertilizer in the cylinder to adjust the humidity, and then carry out chemical reaction and heating compound mixing.
Fertilizer granulation process or compound fertilizer cold granulation process supplemented with a small amount of water, under suitable temperature and humidity conditions, with the help of the rotation of the cylinder, the extrusion force is generated between the material particles and agglomerated into a ball.
(2) Composition of drum organic fertilizer pellet machine:
①Bracket part:
The whole rotating part of the organic fertilizer pellet making machine body is supported by the bracket, and the force is relatively large, so the part of the supporting wheel frame of the machine is welded by medium carbon steel plate and channel steel, and has passed strict quality control and special process requirements, and has reached this level. the purpose for which the machine is used.
In addition to this, the more important thing is the supporting theory fixed on the shelf. Considering that it will cause great friction with the rolling belt of the body, Richi Machinery specially selects high-quality anti-corrosion and wear-resistant materials to improve the service life of the organic fertilizer pellet making machine.
Casting integrated technology is also adopted, and there are hooks at the four corners of the supporting wheel frame, which is convenient for loading, unloading and transportation.
② Transmission part:
The transmission part of the whole organic fertilizer pellet making machine is the most important part of the whole machine. The work of the whole machine has this kind of quality. The transmission frame is welded with high-quality channel steel and has passed the strict requirements.
The main motor installed on the transmission frame both the reducer and the reducer are made of high-quality products with reliable quality. The motor of the organic fertilizer pellet making machine drives the pulley, the V-belt and the reducer to drive the main shaft to make the body work.
③Big gear:
It is fixed on the organic fertilizer pellet making machine body and meshes with the transmission pinion to drive the machine body to work in the opposite direction.
④Rolling belt:
It is fixed on both sides of the body to support the whole body.
⑤Body part:
The most important part of the whole organic fertilizer pellet making machine is the body part, which is welded with high-quality medium carbon steel plate, and has a special rubber lining plate or acid-resistant stainless steel lining plate built-in to realize automatic scar removal, cancel the traditional scraper device, and pass strict quality. Control and special process requirements to achieve the purpose used by this organic fertilizer pellet making machine.
