El component principal de la pedra calcària és el carbonat de calci, i l'adob de pedra calcària és un adob mineral que es basa en pols de pedra calcària. Està compost principalment per carbonat de calci i carbonat de magnesi, i també conté oligoelements com manganès i bor. El fertilitzant de pedra calcària es refereix específicament al contingut de magnesi, mentre que la calç es refereix generalment al calci. Els fertilitzants de pedra calcària tenen un paper vital en l'agricultura. El fertilitzant de pedra calcària processada es pot utilitzar per millorar el pH i la salut del sòl, augmentant així la productivitat agrícola.

2 Types Shunxin Limestone Pellets Granulating Equipment

Large Scale Pan Pelletizer
Double Roller Extrusion Granulator on The Market

Disc Granulator for limestone fertilizer granulation

El disc granulator uses physical action to continuously roll and compact the pedra calcària powder in the disc to form pellets. Disc granulator is suitable for small and medium scale limestone granulating production, it adopts wet granulation method. Limestone powder is gradually polymerized to form spherical particles in an inclined rotating disc by the action of water or binder. It not only has a simple structure and flexible operation, però també té una alta taxa de granulació de més de 93%. Per aquest motiu, it is known as one of the first choices of many mineral fertilizer manufacturers because of its high efficiency.

Double Roller Extrusion Granulator for limestone fertilizer granulation

Double roller extrusion pelletizer utilizes pressure to extrude limestone powder into granules, and then crushed to form pellets. It adopts dry granulation method while processing. Thus it is suitable for materials with a moisture content of less than 10%. The granulation process of this equipment has low energy consumption and the finished granules are of high strength. A més, its cost investment is lower than the above two equipment, if your budget is not enough, then the double roller extrusion granulator is more suitable for you.

What processing steps could improve the quality of limestone fertilizer？

Granular limestone is easier to distribute evenly in the soil, can more effectively adjust soil pH and improve fertilizer utilization.

Granulation can significantly reduce dust flying during the use of limestone, reducing the impact on the environment and personnel.

Granular limestone facilitates packaging, storage and transportation, reducing losses and costs.

Through granulation, limestone can be subjected to a certain degree of slow release treatment. Així, it makes its nutrient release slower and more sustained.

The granulated limestone product has a more regular shape, which improves the market competitiveness and added value of the product.

What is the processing steps of the Limestone Fertilizer Production?

The limestone raw materials are coarsely crushed using a jaw crusher to break large pieces of limestone into smaller particles for further processing. Aleshores, the limestone particles after preliminary crushing are ground into uniform powder by Raymond mill. The limestone raw material fine powder is to facilitate the subsequent mixing and granulation process.

Before granulation, the limestone ground into fine powder needs to be fully mixed with other auxiliary materials, such as binders, nutrients, etc.. This step ensures even distribution of ingredients in the fertilizer particles and improves fertilizer effectiveness.

The limestone fine powder is then becomes the uniform pellets by the granulating machine. Depending on the granulation technology, it can produce different shapes and sizes of limestone fertilizer pellets. During this process, you need to add appropriate amount of moisture or binders to aid granulation. Shunxin granulators, including disc granulator, rotary drum granulator and double roller extrusion granulatorsthat you can choose for your granulation production.

Since the granulated limestone fertilizer contains a certain amount of moisture, so you will need a dryer to reduce the moisture content and improve the storage stability of the fertilizer. A més, you will also need a cooler to cool down the dried fertilizer pellets, peventing deterioration in fertilizer quality due to excessive temperature.

The fertilizer particles that do not meet the size requirements are separated through the rotary screen machine to ensure the uniformity and quality of the product.

Finalment, you can use an automatic packaging machine to quantitatively package the desired limestone fertilizer particles, ready for sale or use.
