The rotary kiln is the main equipment for roasting cement clinker with a lot of advantages. We all know that temperature is the key factor influencing the work of rotary kiln, but do you know how to control and adjust it?
Rotary kiln slip ring thermocouple temperature measurement system uses thermocouple to measure the temperature of rotary kiln internal materials and the air. The two ends of the thermocouple are respectively connected in the two slip rings; each slip ring is respectively coupled with a carbon brush, brushless is fixed to a connecting rod, via a wire connecting to the DCS. Its principle is similar to that of tram power system, so we often call it the rotary kiln slip ring temperature measurement system.
As for the measurement system, a slip ring can only pick one of the hot ends of the thermocouple, several thermocouple cold end share a slip ring. If we want to measure the temperature within the rotary kiln, but also measure the external temperature of the cylinder and the barrel temperature and can depict a precision higher cylinder temperature simulation diagram, you need more than 100 and even more slip rings. However, in most of the existing situation, rotary kiln has generally only three slip rings only used to measure the temperature of the preheating zone, fired zone and insulation zone.
The advantages of this new technology of the rotary kiln include easy installation and compact structure. With the development of science and technology, such a measuring method is precise to be used for measuring the temperature of all kinds of kilns including the rotary kiln.
