This machine absorbs solid fertilizer technology from both domestic and foreign sources, and is a new generation of practical fertilizer processing equipment developed in combination with China's national conditions. Based on the soil nutrient status, crop fertilizer requirements, characteristics, and target yield of fertilizer sales in different regions, the required amount and proportion of different nutrients are calculated. After mechanical mixing, it is generally not packaged in special packaging and can be stored for a long time before being directly sent to the field for practical use.

The overall requirements for basic fertilizers in blended fertilizers are uniform particle size, low moisture content, good particle strength, and no clumping during storage. The consistency of particle size is not only required for the upper and lower limits of particle size, but also for their similar particle distribution. Therefore, analyzing the particle size distribution of different raw materials before mixing fertilizers is an important step to ensure the quality of blended fertilizers.

This device has a novel design and strong practicality. It mainly consists of a feeding system, a high-precision mixing system, a storage system rack, and an electrical control system. It has the advantages of no material storage in the feeding system, uniform production in the mixing system, self flowing packaging, and continuous production.
