What is a rotary kiln?
Rotary kiln refers to rotary calcination kiln (commonly known as rotary kiln) and belongs to the category of building materials equipment. Rotary kilns can be divided into cement kilns, metallurgical chemical kilns, and lime kilns according to different materials processed. Cement kilns are mainly used for calcining cement clinker, divided into two categories: dry process cement kilns and wet process cement kilns.
What are the different types of rotary kilns?
According to the appearance, it can be divided into variable diameter activated carbon rotary kiln and diameter rotary kiln. According to the use, it can be divided into cement rotary kiln, ceramsite sand rotary kiln, aged soil rotary kiln, lime rotary kiln, etc. Gas-fired rotary kiln, coal-fired rotary kiln, mixed fuel rotary kiln.
1. Variable diameter rotary kiln
Rotary kiln with front and back diameter changes. Generally, the diameter changes before and after about 30cm. Compared with the traditional diameter rotary kiln, it has the advantages of energy-saving and high output, but it is difficult to process the variable diameter rotary kiln, and it is more difficult to process than the traditional diameter rotary kiln. More stringent requirements for equipment.
2. Diameter rotary kiln
It is a rotary kiln with the same diameter before and after. Our common type of rotary kiln was invented by German Dietz in 1883. After more than 100 years of evolution, rotary kilns have become universal equipment. It has a better effect and higher output than traditional shaft kiln. The processing is simple, but it is more energy-consuming than the variable-diameter rotary kiln.
