Ceramic roller is the "core" of kilns. Nowadays, the kilns become longer and longer, and wider and wider. And the kiln temp that need to burden as well increased correspondingly. According to the introduction of xie tao, the executive director of scien ceramic, who have research and development of cambered ceramic roller, telling us that because of the high temp and the weight of ceramic tiles, the rollers working in the kiln will bend down slightly. In this case, the "bend down" will cause "short shot", ie not in the same line while running in the kiln. When the kiln become longer and longer, the "short shot" like this way will be more and more obviously, even have bump against tiles to tiles and tiles to kiln. Such bumping will cause directly the appearance of "waste products"

It is reported that there are 3 ways to solve the knotty problem of "short shot" in domestic. One of them is to make the kiln bigger, thus to reduce the bumping between tiles and the inner walls of kiln, the other one is to put less tiles in a time, or make the time of putting tiles longer. For example, 4 tiles in a time before, but now, in order to guarantee quality, one time can only put 3 or even 2 pieces of tiles. If this happen, then it is consume very large, but production capacity decrease greatly. Moreover, a lot of ceramic machinery enterprises introduce cambered ceramic rollers in abroad with high price.

Diameter change of cambered ceramic rollers about 1mm to 2mm, although can't see with your naked eyes, but the slight arch, can make the " bend down" of ceramic roller back to the origin line rightly under high temp pressure, and thus make the tiles running through in order. Because of immature techonology, it can't have mass production in domestic in the past, only can rely on import; But the patented product of scien not only fill up the blank of that field in domestic, let the domestic ceramic enterprises have the hope of breaking away from import period, but also make more ceramic enterprises increase production capacity rapidly, and have energy conservation and emission reduction. The people of scien say that about 60% of the domestic ceramic enterprises have such demand, and it can increase 30% of production capacity of the ceramic enterprises. The cambered ceramic roller can be adjusted the " arch" according to the requirement of manufacturers, and it can be used just put it through the kiln.
