Product description
In order to increase the material evenly distributed in the rotor parts of the cross section in good contact with the drying medium, in the cylinder body installation raise plates. Rotary dryer is used for drying materials with a certain humidity or granularity in milling of ores, building materials, metallurgy and chemical industry. Gyro drying machinery has a strong adaptability of materials and it can dry various materials. The operation is very simple and liable. For this reason, it is used widely.
Descriptions:
It is made up of main kiln body and supporting Drive set cooling pipe and supporting drive set, fuel system, electricity Control secondary air set, exhaust dust set and warm-up kiln body etc. The machine has function like: give an alarm for over temperature, give an alarm for over loading, auto control for working temperature, oxygen atmosphere is adjustable in the kiln etc.
