Microwave reducing system for iron ore is popular used in mine industry. This microwave machinery also can be used for sintering alumine, gold, glass ceramic and others. The temperature can be heated to above 1200 centigrade degree.
The principle of microwave heating
Microwave is a sort of electromagnetic wave which frequency is 300MHz to 300GHz .The water molecule in medium materials is polar molecule,under the effect of the rapid change of electromagnetic field,its polarity orientation will alter with the changes of the external electric field with the high-speed,causing the movement and friction of molecule.so that the microwave field energy can be converted to heat energy in mudium to rise the temperature of materials.accomplishing heating ,puffing and a series of physical and chemical processes ,and so ,mircrowave heating is achieved.
The microwave generator includes magnetron, transformer, capacitor, diode and others. In the past, many producer like to use wind -cooled ways to work, but our company has developed new work ways--water cooled which can have long work life and ensure the safe of other spares.
