The more widely known name for the brown coal pelletizer is the ball press machine, mainly used in the production of low and medium nutrient compound fertilizers, as well as the granulation of organic, inorganic compound fertilizers, and elemental fertilizers.

Brown coal pelletizing is one application of the high-pressure double-roll granulation process. It involves compressing brown coal powder through the action of twin rollers, molding the powdered brown coal into spherical, cubic, or other granular forms. After molding, the qualified particles go through screening before entering the next stage of the process.

The brown coal pelletizer, as the main unit in the granulation production line, is divided into seven main stages:

1. 1.Raw Material Preparation: Initially, brown coal needs to be crushed and finely ground for subsequent processing.
2. 2.Binder Addition: A suitable amount of binder is added to the fine brown coal particles to bind them together and form granules.
3. 3.Mixing: The brown coal particles with added binder are mixed thoroughly to ensure proper binding.
4. 4.Pelletizing Machine: The mixed brown coal particles are fed into the pelletizing machine, where mechanical force is applied to shape them into granules.
5. 5.Drying: The formed granules undergo drying to remove excess moisture.
6. 6.Screening: The dried granules are screened to separate any non-conforming particles, ensuring product quality.
7. 7.Packaging: Qualified granules are packaged for sale or storage.

The entire brown coal pelletizing production line boasts high automation, elevated production efficiency, and the ability to effectively process brown coal into granules, thereby enhancing its added value and market competitiveness. Moreover, the production line employs advanced processes and equipment to guarantee product quality and production safety.
