2. The maintenance cost of organic fertilizer equipment is also an important factor affecting the operating cost of organic fertilizer dryers. Reduce equipment maintenance costs, can strengthen the daily maintenance of equipment, regular inspection and maintenance, to ensure the normal operation of equipment, but also can use advanced process technology and equipment, reduce the failure rate.

3, labor costs are also an important part of the operating costs of organic fertilizer dryers. The operation of the dryer requires certain skills and experience, and the salary level of the operator will also affect the operating cost of the dryer. The training of operators can be enhanced to improve operational skills and efficiency, while automation and intelligent technology can also be adopted.

4, material properties and output are also important factors affecting the operating costs of organic fertilizer dryers. Different material properties require different drying processes and equipment, and the yield will also affect fuel consumption and equipment utilization. Therefore, it is necessary to select appropriate drying equipment and process parameters according to different material properties and yields to reduce the operating costs of organic fertilizer production lines.
