How adaptable is the rotary drum granulator to various materials

fertilizer granulator Aug 5, 2024

The rotary drum granulator has good adaptability to various materials due to its working principle and design characteristics, but the granulation effect and process control of different materials may vary. The following is an analysis of the adaptability of rotary drum granulators to different materials:

Organic materials:

High adaptability. Organic materials such as livestock manure, plant residues, etc. usually have a certain viscosity and humidity, which is conducive to forming particles through centrifugal force in a rotary drum granulator. Organic materials may require crushing and appropriate humidity adjustment before granulation.

Inorganic materials:

Good adaptability. Inorganic materials such as phosphate powder, potassium salt, sulfur, etc., although they may lack viscosity themselves, can improve granulation efficiency by adding appropriate binders or through physical and chemical interactions between materials. The granulation of inorganic materials usually requires finer humidity and temperature control.

Compound fertilizer:

High adaptability. Compound fertilizers are usually made by mixing organic and inorganic materials, combining the advantages of both, which can effectively improve the formability and stability of particles. Compound fertilizers may require finer mixing and pretreatment of raw materials before granulation.

Biodegradable materials:

Good adaptability. Biodegradable materials such as biomass waste and biodegradable plastics usually have good formability, and the granulation effect can be improved by adjusting the humidity of the raw materials and adding an appropriate amount of binder.

Special materials:

Adaptability needs to be evaluated. For some special materials, such as those containing high salt content, highly viscous materials, or materials containing hard particles, additional pretreatment steps may be required, such as cleaning, screening, or adding specific additives, to ensure the smooth progress of the granulation process.

additive:

Good adaptability. Additives such as binders and wetting agents can effectively improve the formability of materials and the stability of particles. Reasonable selection and use of additives can significantly improve granulation efficiency and product quality.

Overall, the rotary drum granulator has good adaptability to materials and can handle a variety of materials from dry to wet, from powder to granular** However, for specific materials, it may be necessary to improve their granulation performance through pre-treatment such as crushing, mixing, humidity adjustment, etc. In practical applications, selecting the appropriate granulator and adjusting granulation parameters (such as speed, feed rate, water spray system, etc.) are crucial for obtaining high-quality granular products.

In addition, the chemical properties of the material, such as pH value, salt content, nutritional composition, etc., can also affect the granulation process and the quality of the final product. Therefore, when using a rotary drum granulator to process materials, the characteristics of the materials should be fully considered, and the optimal granulation conditions should be determined through experiments or reference to granulation experience of similar materials.

The difference and process between carbon based fertilizer and organic fertilizer production lines

fertilizer granulator Aug 5, 2024

Many people confuse organic fertilizer with organic carbon fertilizer and think that applying organic fertilizer is to supplement organic carbon. In fact, there are great differences between them in water solubility and organic component functional groups.

Difference between carbon based fertilizer and organic fertilizer

Organic fertilizer generally refers to carbon-containing organic materials made from animal manure, animal and plant residues, and leftovers processed from animal and plant products through an organic fertilizer production line. The main raw materials of organic fertilizer are excrement and straw, which are treated by compost turning machine and fermented and decomposed. Although organic fertilizer contains a lot of carbon, its water solubility is generally less than 10%, mostly around 3%, so the carbon availability is very low. It is difficult for crops to supplement carbon nutrition.

Organic carbon fertilizer refers specifically to fertilizers that are highly water-soluble and contain organic carbon compounds such as sugars, alcohols, and acids (including humic acid) that are easily absorbed by plants.

1. At present, organic carbon fertilizers are classified according to chemical types, including organic acids, such as acetic acid, propionic acid, amino acids, etc.; sugars, such as monosaccharides, disaccharides, and polysaccharides; alcohols, such as ethanol, propanol, and aldehydes.

2. According to the state of existence, it can be divided into solid state, liquid state and gas state.

3. According to the degree of structural complexity, it can be divided into simple carbon nutrients, such as monosaccharides, acetic acid, amino acids, etc.; complex carbon nutrients, such as humic acid, polysaccharides, hormones, peptides, vitamins, etc.

The organic carbon nutrition with complex structure is directly applied to crops, which can save more light energy and have more obvious fertilizer efficiency. Among them, humic acids and amino acid peptides with complex results are high-end products.

The production technology of carbon based fertilizer can be divided into fermentation treatment and chemical degradation treatment. Among them, humic acid and fulvic acid produced by efficient chemical degradation technology with lignite as raw material have high water solubility, do not flocculate in hard water, and have high physiological activity, which is a kind of high-end organic carbon fertilizer. We provide carbon based fertilizer production process, NPK fertilizer manufacturing process and organic fertilizer production line according to user needs.

Why is it necessary to make granules during the processing of organic fertilizer production lines

fertilizer granulator Aug 5, 2024

There are two kinds of fertilizer products processed by fertilizer production equipment: powdery fertilizer and granular fertilizer. Among them, granular fertilizer is more in daily processing. The main purpose of producing granular organic fertilizer by organic fertilizer production equipment is to facilitate bagging and transportation, and prevent the secondary fermentation of organic fertilizer. In the manufacturing of NPK fertilizer, fertilizers with different nutrients are made into compound fertilizer according to the formula to make the nutrients more balanced. In addition, in terms of the degree of sale, it is better to sell granular fertilizer.

The reason why fertilizer is granular

1. It is more convenient to apply. Organic fertilizer has a lighter specific gravity. It is easy to be blown away by the wind when applied in farmland, and it is easy to apply when it is made into granules.

2. Some inorganic components can be added to fertilizer to improve fertilizer efficiency. However, if the powder is added with inorganic ingredients, it is easy to absorb moisture and agglomerate, so it can be made into granules with rotary drum granulator for storage.

3. The water content of powdered materials must be low and must be crushed. The major limiting factor in the production of organic fertilizer is that the water cannot be removed, and it needs to be dried. The pellets can be made without drying. The pelletizing process generates high heat and only needs to be cooled, which is very convenient.
For organic fertilizer production lines, it is very beneficial to carefully analyze and understand information on various aspects of market development. This is why we carefully analyze our current situation in the market in the middle of development, so that we can better implement our development plans in the market, have a strong development position in the market like mechanical equipment, and better play our role in the market.

What kind of raw materials can be processed by the rotary drum granulation machine

fertilizer granulator Aug 5, 2024

The rotary drum granulator can process various types of raw materials, including:

Organic materials:

Such as animal manure (chicken manure, pig manure, cow manure, etc.), crop straw, garden waste, food processing by-products, etc.

These raw materials usually contain abundant organic matter, and after appropriate pretreatment (such as drying, crushing, mixing), they can be used to produce organic fertilizers.

Inorganic materials:

Inorganic salt fertilizers such as phosphate, potassium, ammonium sulfate, etc.

These inorganic raw materials usually have good water solubility and can be used directly as raw materials or mixed with organic materials to improve the physical properties and nutritional composition of fertilizers.

Compound fertilizer:

Mixing organic and inorganic materials in a certain proportion and processing them through a rotary drum granulator can produce organic-inorganic composite fertilizers.

This compound fertilizer combines the advantages of organic and inorganic fertilizers, providing both abundant organic matter and necessary inorganic nutrients.

Biodegradable materials:

Biomass waste, biodegradable plastics, etc. can be used to produce biodegradable granular fertilizers after appropriate treatment and formula adjustment.

Special raw materials:

Industrial by-products such as sludge and slag, after appropriate pretreatment, can also be used as raw materials for granulation.

additive:

In order to improve the shaping effect and nutritional value of particles, appropriate additives such as binders, wetting agents, preservatives, etc. can be added.

When using a rotary drum granulator to process raw materials, it is necessary to consider the physical properties of the raw materials (such as particle size, moisture content, viscosity, etc.) to ensure that the raw materials can be smoothly formed during the granulation process. For some special raw materials, pre-treatment may be necessary, such as drying, crushing, or mixing, to meet the working requirements of the rotary drum granulator. In addition, the chemical properties of the raw materials (such as pH value, salt content, etc.) can also affect the granulation process and the quality of the final product. Therefore, when selecting raw materials, it is necessary to comprehensively consider their availability, economic benefits, and environmental impact.

How much space is needed to place equipment for building an organic fertilizer production line

fertilizer granulator Jul 31, 2024

Requirements of organic fertilizer production site

The small organic fertilizer production line covers an area according to the equipment configuration. The simple organic fertilizer production line occupies a small area, while the large fertilizer production line with complete equipment covers a large area. The simplest fertility equipment configuration covers an area of about 100 square meters, and the smallest fermentation site also needs 100 square meters. The entire plant area also includes warehouses and expected warehouses, which should be included before site planning.

 It is suggested that when you choose the plant area, you should try to choose the larger one instead of the smaller one. If the production scale is larger in the later stage, you only need to add other equipment. If the site selected is small and only suitable for the current use, you will have to choose a new site once the scale is expanded in the later stage.

We produce complete sets of organic fertilizer equipment. We plan NPK fertilizer manufacturing process and organic fertilizer production line for customers free, and design different production processes. In addition, we can configure different production equipment and processes according to different scales and different raw materials (such as livestock manure, straw, mushroom residue, etc.).
When selecting a suitable fertilizer granulation machine, you must know what fertilizer pellet type you want to produce. Maybe you want to have flat ball-shaped fertilizer pellets. Also, you should choose good fertilizer and granules-making plant manufacturers. They can provide professional suggestions, like proper fertilizer granulation equipment maintenance. Remember, maintaining your granulator effectively can prolong your fertilizer pellet mill’s service lifetime.
