The energy saving of granulator can be divided into two parts: one is the power part, the other is the heating part.
Power part energy saving: most of the use of frequency converter, energy saving is by saving the residual energy consumption of the motor, such as the actual power of the motor is 50Hz, and you actually only need 30Hz in production, the excess energy consumption will be wasted, the frequency converter is to change the power output of the motor to achieve the effect of energy saving.
Heating part energy saving: heating part energy saving is mostly using electromagnetic heater energy saving, energy saving rate is about 30%-70% of the old resistance ring.
1. Compared with resistance heating, the electromagnetic heater has a layer of insulation layer, which increases the utilization rate of heat energy.
2. Compared with resistance heating, the electromagnetic heater directly acts on the feed tube heating, reducing the heat loss of heat transfer.
3. Compared with resistance heating, the heating speed of electromagnetic heater is more than a quarter faster, reducing the heating time.
4. Compared with resistance heating, the heating speed of the electromagnetic heater is fast, and the production efficiency is improved, so that the motor is in the saturation state, so that it reduces the power loss caused by high power and low demand.
