Agricultural fertilizers play a key role in improving crop yields and quality. In the fertilizer production process, grinding various raw materials is an important step. Shanghai Zenith has developed and produced new products such as vertical roller mills and European grinding mills, offering integrated grinding solutions for fertilizer raw materials such as phosphate ore, potash ore, and organic fertilizer raw materials. These raw materials can be processed to a suitable fineness to meet the requirements of subsequent fertilizer production processes, improve fertilizer utilization and effects, and promote the sustainable development of agriculture.
Material of suitable size is fed into the main machine for grinding, and the fine powder after grinding is sent to the analyzer for grading under the action of the air flow of the fan, so that the fine powder with qualified fineness can enter the collecting stage.
The dust gas enters the cyclone collector through the outlet pipe. Under the action of centrifugal force, most of the finished fine powder is separated. Redundant gas is discharged and sent to pulse dust collector. Then it becomes clean gas. Fine powder collected by cloth bags is transported to the conveying stage through screw conveyor.
The finished powder collected by dust collector and cyclone collector is sent by screw conveyor to the next process or into finished product tank.
Finer phosphate rock powder can increase the contact area of phosphate fertilizer in the soil, making it easier to be dissolved by acidic substances in the soil, thereby improving the effectiveness of phosphorus and allowing crops to better absorb and utilize phosphorus.
Fine-grained potassium fertilizer can dissolve faster in the soil, so that potassium can be supplied to crops in a timely manner to meet their potassium needs during growth. This is especially beneficial for some crops that are sensitive to potassium, such as bananas and potatoes, and is more conducive to improving crop yield and quality.
Maintain the activity of organic matter and the effectiveness of nutrients in fertilizers, while ensuring appropriate decomposition and action speed in the soil to continuously provide nutrition for crops.
