With the rapid development of the national economy and the continuous progress of the chemical industry, cement rotary kiln is becoming more and more important in the industry. Hongke Heavy Industry is a well-known manufacturer specializing in the production of cement rotary kiln. Its technology and technology can provide better cement rotary kiln equipment for customers.
This paper describes the drying techniques of cement rotary kiln by Hongke Heavy Industry Experts. The bottom of cement rotary kiln is made of refractory concrete, while the walls and roofs are made of refractory bricks. Before the cement rotary kiln is put into operation, the new furnace must be baked in order to dry the moisture in the masonry.
The main steps of cement rotary kiln drying are:
(1) laying iron plates at the bottom of the cement rotary kiln and burning wood on the iron plate, thus drying and laying material. After drying, remove the iron plate and clean the furnace.
(2) Fire stoves are built at four relatively symmetrical water jacket ports of cement rotary kiln, firewood is burned in the furnace, and waste gas is burned through the water jacket ports to dry the masonry. After drying, remove the stove and secure the water jacket.
(3) use gas, heavy oil, firewood and heavy oil to combine oven. When drying cement rotary kiln, do not overheat, ensure that the temperature of the kiln rises to 200 degrees within 12 hours after ignition, and then keep this temperature for a period of time, then the drying will be finished.
In the drying process of cement rotary kiln, the uniformity of temperature in the furnace is very important. Besides the adjustment of wood, it also needs the adjustment of natural air extraction from the furnace. After drying in cement rotary kiln, there are a few bulging bubbles on the surface of heat-resistant concrete at the air distribution board of the bottom of the kiln, which may block the side eye of the wind cap, so it is necessary to remove bubbles. Practice has proved that using the above methods to bake the kiln will not produce cracks in the brick joints of the wall and the heat-resistant concrete of the cement rotary kiln, and the baking effect is better.
