Product Description

1 Introduction to electromagnetic heating of 80KW granulator

The electromagnetic heating system of 80kW granulator first rectifies 380v50 / 60Hz AC into DC, and then converts DC into high-frequency high-voltage power with frequency of 8-20kHz. 

When the high-frequency high-voltage current with high-speed change flows through the coil, it will produce an alternating magnetic field with high-speed change. 

When the magnetic force line in the magnetic field passes through the magnetic metal material, it will produce countless small eddy currents in the metal body, making the metal material itself heat at high speed, so as to achieve the purpose of heating the material in the metal barrel.

3 Advantages of 80KW granulator electromagnetic heater

1. The electromagnetic induction heating mode of 80kW granulator is used to replace the original heating ring heating, open fire heating and heating pipe heating, which completely solves the problems of too high ambient temperature and serious environmental pollution. Compared with the original heating mode, it saves 30% power and costs for you.

2. After the transformation, the material barrel generates heat by itself, so that the heat will not be lost to the air under the thermal insulation of the thermal insulation layer.

3. 80kW granulator electromagnetic heaters adopt unique design structure, with uniform heating surface temperature and accurate temperature control, so as to prolong the service life of barrel and screw rod.

4. The electromagnetic heater of 80kw granulator has high heating efficiency and uniform heating, which can significantly reduce the heating time and improve the product output and quality.

5. The 80kW granulator electromagnetic heater hardly radiates heat to the peripheral space, with high power density, and can be heated to a temperature above 350℃;

6. The heat conversion efficiency of the high-efficiency and energy-saving mode is more than 90%, and the power consumption is about 30% lower than that of the resistance coil heating mode under the same conditions;

7. The heat is concentrated inside the heating body, the external heat dissipation is almost zero, the surface of the equipment can be touched by the human body, and the ambient temperature is reduced from more than 60℃when the original resistance coil is heated to normal temperature, which greatly improves the working conditions on the production site, effectively improves the production enthusiasm of workers, reduces the heat stroke rate and reduces the ventilation and cooling cost of the plant;

8. The effect of electromagnetic heater of 80kw granulator is more obvious in water material, and the effect of dry material machine is also good.
