Pelleting Equipment

How to improve the granulation rate of using rotary drum pelleting machine?

Drum steam granulation is a process to realize thermal granulation. The equipment by improving the temperature of the material, and increase the solubility of salt in the pelletizing water system material, so that the water required by the material granulation can be obtained under low moisture, so as to effectively reduce the heat consumption required in the drying process, improve production efficiency. Therefore, the performance of granulation is the key to the yield and quality of compound fertilizer produced by drum granulation machine. Today, let’s discuss how to improve granulation performance.

1. The main factor of pelletizing rate of organic fertilizer is the frequency and time of material rolling in pelletizing machine.

The working principle of the wet type of pelleting equipment is that the material of organic fertilizer depends on the surface tension, add the right amount of liquid phase, and disperse the material into small particles. When running at high speed, many small particles roll into a ball. In a certain time to control the correct category line, improve the ball qualified rate. In production, if the pelletizer and material friction is not at the same time, there will be these two conditions. The machine is that the machine internal smooth degree is large, so that the friction force decreases, causing the material can not roll, resulting in unable to produce finished particles. If we have this situation, we can adjust the speed of the machine and install a small copy board inside. There is another case is the machine wall internal sticky more serious, this causes uneven material particles, because the material wall will know to rise to the highest, together from the top of the top down. There are two main reasons for this situation. One is that the inside of the machine is not smooth. This situation can be solved by increasing the internal finish of the pelletizer. There is another kind of material viscosity is too high, this situation we use to change the material formula, reduce humidity, reduce viscous materials can be solved.

2.The key to make qualified finished particles by the granulation mechanism of organic fertilizer is to stabilize the material ratio.

Drum granulation production technology is to bury steam pipe in the material bed, and then install spray pipe above the material bed, under normal circumstances to provide steam heat and water. Through steam to improve the humidity and viscosity required by the material, will not cause excessive water content, reduce drying load, make water distribution evenly. If the humidity of the material is not enough, it can also be supplemented with water. If the material humidity is not uniform, it will be difficult to form a ball or affect the uneven shape of particles. It may be that the steam nozzle is not properly installed. We can increase the steam nozzle to increase the receiving area of steam to solve this problem.

3.The pelletization rate is also based on reasonable material ratio.

The material ratio referred to here mainly refers to: 1. Reasonable collocation of raw material fineness. According to the operation summary of a number of organic fertilizer manufacturers, the fineness of the whole raw material should be matched as follows: 100-60 mesh raw materials account for about 30%-40%, 60 mesh raw materials with a diameter of 1.00 account for about 35%, small particles with a diameter of 1.00-2.00 account for about 25%-30%. In principle, the finer the material, the smoother the surface of the finished particle. However, in the production process, the use of super proportion of high fineness materials is prone to some bad problems, such as often appear too large particles, irregular particles, materials stick to the wall and so on. 2. Viscous materials and dispersive materials need to be reasonably matched. In production, the proportion of viscous materials is high, and it is easy to form balls. The proportion of dispersed materials is high, and the balls agree to disperse, and the fine powder will be relatively large. In general, in the conventional formula, the proportion of sticky raw materials for low concentration fertilizer is 45%-50%, and the proportion of sticky raw materials for high concentration fertilizer is 35%-40%, which also needs to be combined with the fineness of the material. If the collocation is not good, there may be no fine powder, no particles, or particles are not round, uneven size and other problems.

4. Chemical reactions between materials should be considered in preparation.

After some materials are made up, free water can be precipitated in the production process, making material moisture exceeds the standard and hindering normal production. After some raw materials are matched, the humidity of mixed materials will be greatly reduced. In the production process, normal production cannot be realized due to a large amount of moisture absorption. Therefore, chemical reactions between materials must be considered in the formulation to achieve a reasonable match.

4. Comprehensive water content of mixed materials.

The water content of synthetic raw material has a direct effect on granulation. After mixing, some materials are mixed into mud even without steam and water, making normal production impossible. Therefore, keeping the water content of the material low is conducive to the addition of steam during granulation, thus improving the temperature and viscosity of the material, and improving the compatibility and pelletization of the material.

5. Reasonable amount of return material.

Generally qualified particles are about 55%, so the amount of material returned is higher, which directly affects the production efficiency of finished particles. The disadvantage of the drum granulator is that the finished product has less particles, more powder, and large amount of return, which affects the luster and roundness of particles. If the return amount can be controlled between 30% and 35%, the formation of large particles can be effectively controlled.

How to Select the Organic Fertilizer Pan Granulator?

The annual output of 30,000 tons of organic fertilizer disk granulator is divided into plane torsion disk granulator and skewed disk granulator two categories, is the production of spherical particles of organic fertilizer building. In the actual production application, how should we choose the organic fertilizer disk granulator?

Select the disk granulator, first familiar with the function of the disk granulator characteristics. Planar torsion plate type of granualtor is characterized by the main body of the fixed mechanism, the disk inside the torsion, will enter the disk of the material by centrifugal torsion, rotating into a ball. Plane torsion disc granulator running speed is relatively high, good adhesion, relatively large density, low yield requirements of the material is more suitable. It is characterized by high particle symmetry and fast discharging.

Skewed disc pelletizer adopts a relatively ancient process, the base of the disc pelletizer is fixed, driven by the motor delay machine operation, and then driven skewed disc pelletizer outside the disk torsion, into the material rotation into the ball. The rotation speed of this kind of disc granulator is low, and the skew Angle can be adjusted. It is suitable for the production of spherical particles of organic fertilizer, compound fertilizer, chemical raw materials, biological fungal fertilizer and biological fertilizer. It is characterized by high yield and easy operation and application.

Familiar with the function of the pan making pellets equipment, can reasonably select the disc granulator to provide sponsorship. With the updating of organic fertilizer buildings, the new horizontal centrifugal organic fertilizer granulator has become the protagonist of the disk granulator, and the output and particle symmetry has been promoted to a new level. Horizontal centrifugal spherical particle organic fertilizer granulator adopts the operation principle of drum granulator, connects the rotor of organic fertilizer mixer, and becomes a new type of organic fertilizer granulator of round ball particles after improvement. This kind of granulator has high output, low power consumption, less failure, saving labor, and good continuous granulation effect.

Advanced Craft of Making Organic Fertilizer Granules

The production process of making organic fertilizer granulation mainly consists of screening and magnetic separation of about 30%-35% of the organic waste containing about 30%-35% of the water content after fermentation, and then granulating and drying to prepare round-particle organic fertilizer. Adding functional bacteria can produce bio-organic fertilizer. Adding nitrogen, phosphorus, and potassium (total nutrient content less than 15%) can produce organic and inorganic fertilizers.

After the fermented organic waste is subjected to magnetic separation and screening, the raw materials of the binder and other components that need to be compatible are metered and mixed according to the ratio requirements, and are upgraded to a multi-dimensional high-efficiency mixer by a bucket elevator for rapid mixing. The mixed material slips out into the mixed silo, and is fed uniformly and continuously to the stirring teeth type of granulating machine by the disc feeder to form columnar particles; the columnar particles are polished by the round particle polishing and shaping machine to form spherical glumes. The belt conveyor is sent to the drying, cooling, and screening machine (three-in-one model), and the particles are dried at low temperature and large air volume (<65°C) in the front section of the drying cooling and screening machine, and then enter the cooling section for air cooling and sufficient cooling. After the material enters the cylinder of new type fertilizer pelleting machine, the sieved finished particles are sent by the elevator to the finished product silo, and are measured by the packaging system, packaged and stored. The large sieved particles are crushed and then returned to the mixing and granulation System. The small particles sieved (basically no powder) can be made into small packages and sold directly.
