The difference between organic fertilizer dry granulator and wet granulator

When purchasing an organic fertilizer granulator, many customers are confused. Facing the equipment classification, they don’t know what kind of equipment to choose. The following is a detailed introduction for reference.

We often receive many inquiries from customers about fertilizers related to the organic fertilizer granulator. Many customers find it difficult to distinguish what kind of fertilizer they need; the difference is to choose the appropriate granulation method according to the use requirements of the material. Organic fertilizer granulator is just a general term, and there are subdivisions and branches under it. It is mainly divided into two categories: dry method and wet method:

Dry organic fertilizer granulation:

It mainly refers to products with relatively low moisture content in materials. Generally, moisture content below 10% is a zero threshold value. (There are also very few materials that can reach 16%, such as: some materials themselves only contain crystal water) Dry granulation produces mostly irregular particles (such as; common granular potassium fertilizer) or more generally, small crushed stones similar in shape. With the current domestic industrial upgrading and environmental protection requirements becoming more and more stringent, many chemical and building material powders need to be made into particles.

Wet organic fertilizer granulation:

There are many kinds of equipment and methods in wet granulation for materials with a moisture content of more than 20%.

Such as: disc granulation, drum granulation, screw granulation, these methods have been continued many years ago, and have made great progress through continuous improvement and continuous improvement of the use environment and processing requirements of different materials.

For example, the granulation of organic fertilizers, which has been popular in recent years, mostly has a particle size between 1mm and 6mm, and the above methods are used.

Compared with wet granulation, dry granulation consumes less energy and is more environmentally friendly. It does not need to be dried, and does not add water and binders, so it will not change the material properties; this is also the difference between dry granulation and wet granulation. Several advantages of granulation. It is more suitable for industrialized mass production. In another case, some materials require relatively small particle size, and products between tens of mesh and one hundred mesh can also be reduced by airflow, spray, and flash drying.

Advantages of organic fertilizer granulation production:

Organic fertilizer processing and granulation is now a project with very promising market prospects, especially in recent years, due to strict environmental protection inspections, the pollution of livestock and poultry manure cannot be solved. Many farmers want to solve the pollution problem caused by livestock and poultry manure, which is better The solution is to use a complete set of organic fertilizer equipment to process organic fertilizer. The complete set of organic fertilizer equipment has an annual output of 10,000 to 30,000 tons, and an annual output of 30,000 to 100,000 tons. Cheap powdered organic fertilizer production line, or choose simple organic fertilizer processing equipment, namely organic fertilizer turning machine, semi-wet material pulverizer, drum screening machine.
