Although the pan pelletizer has traditionally been widely used in the production of fertilizers (such as compound fertilizers and organic fertilizers), its application has gradually expanded to other industries with continuous technological advancements and increasing environmental requirements. Here are several potential growth directions beyond fertilizers:

1. Environmental Protection Sector

Sludge Pelletization Treatment: Municipal sludge, papermaking sludge, and other types are processed and pelletized to facilitate transportation and reuse, making it particularly suitable for sludge resource utilization projects.

Flue gas desulfurization gypsum pelletization: The byproduct from thermal power plants desulfurization process can be formed into pellets using a pelletizer for applications such as building materials.

Fly ash pelletization: The process involves pelletizing industrial waste such as fly ash to reduce dust pollution and achieve resource utilization.

2. Bioenergy

Pelletizing organic waste: Organic waste such as straw, livestock manure, and food waste is fermented and dried before being pelletized for use as biomass fuel or soil amendment.

Microbial fertilizers, humic acid fertilizers: Combined with agriculture, granulation facilitates microbial survival, transportation, and field application.

3. Building Materials Industry

Granulation of expanded clay and bentonite: After granulation with bentonite, coal gangue, and other materials, it is used to produce lightweight aggregates or adsorbent materials, widely applied in construction, adsorbents, filtration media, and other fields.

Forming of refractory material particles: In the production of refractory bricks, castables, and similar products, it is sometimes necessary to preform powdered raw materials into specific particle sizes to enhance product performance.

4. Metallurgy and Mineral Processing

Pelletized ore: such as iron ore powder and nickel ore powder, which facilitates blast furnace smelting through pelletization, reduces dust loss, and improves smelting efficiency.

Battery material granulation: Some new energy battery materials (such as lithium iron phosphate precursors) also employ wet granulation to improve particle size distribution and flowability.

5. Food and Feed Industry

Feed additive pelletization: For materials such as trace element premixes and mineral powders, a disc pelletizer can be used to prevent segregation and improve uniformity.

Small-batch pelletizing of pet feed: Certain special formulations of pet food or aquafeed can also adopt the disc pelletizing process.

Summary:

The future growth potential of the disc pelletizer lies in its advantages of low energy consumption, strong adaptability, and controllable particle size, making it suitable for the balling process of various powdered or fine-grained materials. Under the overarching trend of the "dual carbon" goals and resource recycling, industries such as environmental protection, energy, biomass, and new materials will be key areas for its expansion.
