Determine the production capacity: For example, annual output in tens of thousands of tons, or hourly output in tons. This is essential for determining the price.
Determine the shape of the granules: Options include powder, columnar, flat spherical, or standard round. Commonly used granulation equipment includes disc granulators, rotary drum granulators, wet granulators, double-roller extrusion granulators, flat die granulators, and ring die granulators. The selection of the granulator should be based on the local fertilizer market. Different granule shapes require different equipment processes and result in different prices.
Determine the equipment configuration level: Higher configurations come with higher prices but reduce labor requirements and ensure stable, high-yield production. High-end configurations typically include automatic batching systems, automatic packaging systems, automatic quantitative feeding systems, and cyclone dust collectors combined with wet scrubbers.
Determine the type of fertilizer to be produced: Whether it is for compound fertilizer or organic fertilizer. For the same production capacity, organic fertilizer equipment generally needs to be larger in size than compound fertilizer equipment because organic materials have higher moisture content and the added microbial strains are sensitive to high temperatures. Organic fertilizers are generally categorized into four types: pure organic fertilizer, organic-inorganic compound fertilizer, bio-organic fertilizer, and compound microbial fertilizer. Different types require slight variations in equipment.
Select the compost turner (fermentation equipment): Common fermentation methods include windrow composting, shallow trench composting, deep trench composting, tower composting, and rotary drum composting. Different methods require different equipment. Generally, shallow trench turners are more suitable for aerobic fermentation principles. The advantage of shallow trench turners is that they better align with aerobic fermentation, preventing anaerobic conditions, ensuring thorough fermentation, and accelerating the process.
Determine the environmental protection requirements: In areas with lower environmental standards, heavy sedimentation dust collectors are sufficient, resulting in lower equipment investment. In areas with strict environmental standards, heavy sedimentation dust collectors combined with wet scrubbers are required to meet air emission quality standards.
