Its absorption and utilization rate is relatively high. More importantly, it can be applied to drip irrigation and other facility agriculture to realize water and fertilizer integration, achieve water, fertilizer and labor saving efficiency. In the production process of water-soluble fertilizer, crushing equipment is needed to crush the raw materials of fertilizer to improve the production and processing efficiency of water-soluble fertilizer.

Although the rolling and extruding of the crushing rollers on the raw materials reduces the maintenance of the crushing structure, large pieces of raw materials often cannot enter the crushing rollers and the crushing disc for crushing, causing some raw materials to remain in the device, reducing the processing efficiency. When a large amount of raw materials are processed, the size of the raw materials after crushing in one pass often cannot meet the sieving requirements. Due to the large amount of raw materials processed at the same time, the raw materials often move with the rotation of the crushing rollers in the crusher, making it difficult to quickly crush again, thus reducing the crushing efficiency.

[0004] 2. Part of the raw materials of water-soluble fertilizer can also be dissolved in water. To prolong the service life of the equipment, the equipment needs to be cooled down when crushing the raw materials. The cooling efficiency of the equipment outside and the cooling of the crushing structure through heat transfer is low. Cooling the equipment inside with cold water may cause the dissolution of water-soluble raw materials, which is not convenient for subsequent processing. Cooling with air may cause the escape of granular raw materials. Various cooling methods are difficult to cool the raw material crushing equipment of water-soluble fertilizer, increasing the maintenance cost of the equipment. UTILITY MODEL CONTENTS
