How To Solve The Temperature Control Problem Of Internal Mixer?

2023-05-06

The temperature accuracy of the internal mixer is directly related to the results of ingredient research and development. Generally, the heating methods used are electric mold heating and oil heating. The power used by the electric heating of the Internal Mixer and the processing method of the mold are different, and the results are different. The specific solutions are as follows:

Internal mixer surround type electric heating

Unlike the Dispersion Kneader, the power of a single heating wire of the internal mixer can reach 2.1KW. The temperature difference between the two ends of the effect is more than ten degrees, and more tens of degrees. The main reason is that the heating wire cannot be tightly fitted or is not in contact with the inner wall at all, forming a hollow dry smelting. Using this method, the main performance is that the heating wire will be deformed after dry burning for a period of time, difficult to replace, and uneven temperature. However, because the power of the heating wire is relatively large and the structure is relatively strong, it is not easy to be burned out.

Internal mixer single-head rod electric heating tube

The maximum diameter of a single heating wire single-ended rod is 19.8, and the normal power is 1.7KW. This method has a relatively uniform temperature and an accuracy of ±2°C. The disadvantage is that the heating speed is slow and the power is low. If the power is increased, the heating tube will be easily burned out, and the replacement time and frequency will be increased.
