Although disc granulators have traditionally been widely used in the production of fertilizers such as compound fertilizers and organic fertilizers, with the continuous advancement of technology and the improvement of environmental requirements, their application fields have gradually expanded to other industries. Here are several potential growth directions besides fertilizers:
1. Environmental protection field
Sludge granulation treatment: Municipal sludge, papermaking sludge, etc. are treated and granulated for easy transportation and reuse, especially suitable for sludge resource utilization projects.
Granulation of desulfurization gypsum: The by-products of desulfurization in thermal power plants can be formed by granulators and used for building materials and other purposes.
Granulation of fly ash: Granulation treatment of industrial waste such as fly ash to reduce dust pollution and achieve resource utilization.
2. Biomass energy
Organic waste granulation: Organic waste such as straw, livestock manure, and kitchen waste are fermented and dried before granulation, and used as biomass fuel or soil amendments.
Microbial fertilizer and humic acid fertilizer: combined with agriculture, granulation is beneficial for the survival, transportation, and field application of microorganisms.
3. Building materials industry
Granulation of ceramic particles and bentonite: The granulation of bentonite, coal gangue, and other materials is used to manufacture lightweight aggregates or adsorbent materials, which are widely used in fields such as construction, adsorbents, and filtration media.
Particle forming of refractory materials: In the production of refractory bricks, castables, etc., it is sometimes necessary to prefabricate powder raw materials into one Determining particle size helps improve product performance.
4. Metallurgy and Mineral Processing
Mineral powder pellets: such as iron ore powder, nickel ore powder, etc., are granulated to facilitate blast furnace smelting, reduce dust loss, and improve Improve smelting efficiency.
Granulation of battery materials: Some new energy battery materials, such as lithium iron phosphate precursors, are also modified by wet granulation Good granularity distribution and fluidity.
5. Food and feed industry
Feed additive granulation: such as trace element premix, mineral powder, etc., in order to avoid stratification and improve uniformity, a disc granulator can be used.
Pet feed small batch granulation: Some special formulations of pet food or aquatic feed can also use disc granulation technology.
Summary:
The future growth point of the disc granulator lies in its advantages of low energy consumption, strong adaptability, and controllable particle size, which are suitable for the balling process of various powder or fine particle materials. Under the trend of "dual carbon" goals and resource recycling, industries such as environmental protection, energy, biomass, and new materials will be its key expansion directions.
