Water control of drum granulator during granulation

fertilizer granulator Oct 29, 2020

In chemical processing industry, rotary drum granulator is widely used in organic fertilizer production line and NPK fertilizer production line. In the granulation process of the drum granulator, the coarsening in the pellet is mainly in the form of cladding, so the material circulation volume should be larger, so as to provide a coarser core for the cladding process, and the water injection volume should be smaller, so as to reduce the water absorption of the core.

When pelletizing by bonding or “gathering”, the materials are smaller, because the materials in the drum are 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.

Difference between the production machines of organic fertilizer and compound fertilizer

fertilizer granulator Oct 29, 2020

The internal quality of organic fertilizer mainly depends on raw material fermentation and product formula. The key factors affecting the fermentation of organic fertilizer production process are: microorganism, carbon nitrogen ratio, carbon phosphorus ratio, water content, pH value, aeration control. If one factor is not properly controlled, the whole fermentation will be affected, resulting in incomplete fermentation of materials or long fermentation time. If the material fermentation is well formulated, the effect is better than inorganic fertilizer, and the cost is also low. It can also improve the living environment of plants and become green fertilizer. The formula of organic-inorganic compound fertilizer is different from that of inorganic fertilizer, and there are also differences in different soil and crop formulas. The organic fertilizer manufacturing process is different from that of compound fertilizer, and the fertilizer production machine is also different.

Difference of production technology between compound fertilizer and organic fertilizer

The machines required for the organic fertilizer manufacturing process is mainly divided into two parts, fermentation part and production granulation part. NPK fertilizer manufacturing process is mainly granulation processing. The granulation part of organic fertilizer is also different from that of inorganic fertilizer.
Because organic raw materials are different from inorganic raw materials, the production of inorganic raw materials can be mainly based on the formula of raw materials, which is mainly chemical reaction. If the formula is proper, the operation is skilled, the pelletizing rate is very high, and the production is relatively easy. Roller granulator is suitable for dry granulation of NPK fertilizer and disk granulator is suitable for wet granulation.
For organic fertilizer, granulation is difficult even if the raw materials are fermented well, because the characteristics of organic raw materials are light, rough, low adhesion, and a wide variety of organic raw materials. Raw materials have different characteristics, so when selecting fertilizer granulating machine, special attention should be paid, otherwise not only the output will be affected, but also the appearance of the product is not beautiful. Rotary drum granulator is generally used for granulation of organic fertilizer and compound fertilizer.

When selecting the organic fertilizer production machine, we should pay attention to the following points: output of organic fertilizer production, organic raw materials, fermentation mode, fertilizer granulator machine, mechanization degree of organic fertilizer equipment. These are key factors in purchasing equipment. In short, organic fertilizer production is a relatively complex process, but the risk is relatively small, which can bring rich profits to the enterprise.

Main advantages and disadvantages of granulation process and technology of potash fertilizer

fertilizer granulator Oct 21, 2020

The potassium fertilizer is fed into the disc granulator, so that the material gradually piles up by itself until it reaches the required particle size. When the raw materials are piled up on the disc, the binder can be added to support the agglomeration of the materials. Since water will be added to the disc during granulation, additional drying process is required for the fertilizer production line when using this method of rolling raw materials into balls.

Advantages and disadvantages of potash fertilizer granulation

1. The granulation of potash fertilizer has many advantages. This non pressure agglomeration technology can produce particles with smaller density, so that the particles can decompose rapidly. Because most of the potash fertilizer can be used as fertilizer after processing, the ability to decompose and provide nutrition faster is the inducement to choose potash fertilizer particles. It is an ideal product for fertilizer compounds with fixed formula requirements that require rapid nutrient delivery. The round granular potash fertilizer is also easy to handle, and the fineness of potash fertilizer is lower than that of compacted particles.

2. The main disadvantage of potash granulation is that the processing cost is high, and potash particles are considered as high-quality products. Therefore, it is not generally produced like compacted particles. However, it is worth mentioning that the disc granulator is the ideal choice (as opposed to the fertilizer extrusion production process) due to the hardness of potassium salt in the treatment of some potassium salt derivatives.

Granulation technology of potash fertilizer

Disc granulator machine is widely used in the field of potash fertilizer granulation, NPK fertilizer granulator can also be used in the processing of potash fertilizer and a variety of compound fertilizers. The disk type fertilizer granulator is a new type of fertilizer granulator: its granulation rate can reach more than 95%, the main gear of the granulator is quenched with high frequency, the service life is doubled, the disk of the disc pan granulator is of arc structure, lined with high-strength fiberglass, and the bottom of the disk is strengthened by a number of radiation steel plates; it is durable and never deformed. After the potassium fertilizer powder enters into the pelletizing plate, the material continuously rotates and is sprayed by the pelletizing plate, so that the materials stick together to form spherical particles.
