In the fertilizer production line, the fertilizer granulator is the key equipment, and the choice of its motor power directly affects the production efficiency and energy consumption. Many enterprises in the purchase of equipment, that the greater the motor power, the higher the output of pelletizer, more stable operation. But in fact, the motor power is not the bigger the better, reasonable matching is the key.
1. Excessive power increases energy consumption and reduces economic efficiency
The greater the motor power, the higher the energy consumption. If the power of the granulator used in the NPK fertilizer production line is far more than the actual demand, the machine may not be able to fully utilize the rated power during operation, resulting in waste of electrical energy and increased production costs. In the long run, unreasonable motor configuration will reduce the economic benefits of equipment.
2. The service life of the device is affected and the maintenance cost is increased
Excessive motor power may cause the equipment to withstand excessive load impact during operation, increasing the wear of mechanical components. For example, the instantaneous current when the motor is started is too large, which may cause additional damage to components such as bearings and reducers and shorten the service life of the equipment. At the same time, the motor load is too low may also lead to increased wear of the carbon brush, increasing maintenance costs.
3. Granulation effect may decline
The operation of the fertilizer granulator needs a reasonable power match, if the motor power is too large, the speed may exceed the optimal granulation speed, resulting in insufficient stay time of the raw material in the granulation disc or cylinder, making the particle molding unstable and affecting the quality of fertilizer. On the contrary, a motor with a reasonable matching power can ensure uniform granulation of materials and improve the product pass rate.
4. Choose the right power to improve production efficiency
Reasonable motor power selection should be based on production line capacity, material characteristics and equipment structure. For example, for NPK fertilizer production lines, different types of granulators (such as disk granulators, extrusion granulators, etc.) have different motor power requirements. Enterprises in the purchase, should be combined with the actual production needs, communicate with the equipment manufacturers, choose the most suitable motor power, rather than blindly pursue high power.
