What is the production record for rotary kilns in China?
Thread Content
Our factory uses a rotary kiln with a diameter of 3 meters to produce zinc oxide powder. The interior lining of the kiln is made of ordinary phosphate refractory bricks. Production continued from December 9, 2006, until November 20, 2007, when the kiln was shut down for brick replacement. Excluding the 3 periods of shutdown for maintenance, the effective production time to date is 268 days. I wonder if there are any other factories in China with a longer annual operating period than ours
I’m not very familiar with your industry. In other industries, such as the chromium salt industry, our factory’s baking kilns can operate for over a year; I’ve just heard that in some cases this period can reach up to three years. The reason for this might be the difference in materials, as well as the properties of the bricks, such as their wear resistance and insulation capabilities.
My factory has been in operation for about 100 days. I’m very envious of you; could you share some of your experiences?
There’s not really any experience involved; it comes down to precise operations. When it comes to material feeding, it’s essential to maintain uniformity – avoiding fluctuations in the amount of material fed. The speed of the kiln and the temperature inside it also need to be strictly controlled. In short, stability is of utmost importance.
Thank you! I haven’t considered this issue yet.
One I saw had 259 days by September, and it was still running at that time
I work in the paper industry; we also have rotary kilns, but they’re different from yours!
For the one on the 8th floor, is it made of zinc oxide refractory material? Does the 259-day period exclude maintenance time? If so, are ordinary phosphate refractory bricks still used? Thank you!
We burn molecular sieves. The temperature inside the cylinder is between 700 and 800 degrees. It can be used for 5 years without the need to service the furnace body. Ordinary refractory bricks.
It is a clinker kiln used in the alumina sintering process, with a firing zone temperature of over 1300°C. The time since its last major repair has been counted from then; as of September, it had been 259 days, and at that time it was still in operation. It’s not known whether another major repair has been carried out yet. This post was last edited by haibao on 2007-12-21 16:25]
Hello, poster! I’m a newcomer to the paper industry; I use rotary kilns to burn limestone to produce slaked lime. I was wondering if all these rotary kilns are more or less the same? Could you tell me something about the startup and commissioning of a single rotary kiln? The sequence before and after startup, inspection items, precautions, and more! Thank you first!
