Hongxing rotary kiln is low energy consumption and stable operation

Rotary kiln outside decomposition technique is the dry hollow kiln, made Bohr kiln, suspension preheater technology developed on the basis of a relatively advanced core technology. The original rotary kiln outside decomposition kiln for straight cylinder, this kind of kiln makes preheater heat exchange and decomposition furnace precalcining efficiency low, resulting in kiln system low yield. But after years of production practice has proved efficient kiln outside decomposition rotary kiln high production efficiency, low energy consumption, stable operation. support rollers, bearings, tires and support rollers are used to ring to support the weight of the rotary kiln used. Tire ring is set in the kiln shell, between it and the kiln shell is not fixed, rotary kiln shell and tire ring plus a piece of iron between the separated ring and the tire to retain a certain gap between the kiln shell, not too much not too small. If the gap is too small, the expansion of the rotary kiln shell limited by the tire ring, brick kiln easy to destroy. If the gap is too large, the kiln shell and the relative movement between the tire ring, friction is more interest, but also make an elliptical deformation of the rotary kiln shell is more serious.

In some hot rotary kiln, because of withstanding the high temperature material corrosion, erosion and abrasion, more use of magnesite chrome brick, magnesium aluminum bricks, high aluminum bricks and so on, these bricks of the thermal conductivity, heat loss of kiln body is large, in order to save energy and prolong the service life of kiln lining, in the build by laying bricks or stones to work outside layer heat insulation brick. These two kinds of brick can only build by laying bricks or stones into two respectively each link of the circle, it could not make kiln masonry form a whole. Lining bricks often is not due to wear and corrosion damage, but due to temperature fluctuations change, make it an uneven shrinkage, especially with the thermal insulation layer of bricks, it is easy to a single piece of drop, serious can cause the ring fall off, had a great influence on rotary kiln lining body life.

At the present, Hongxing mining machinery has set up three state level machinery research institutes, and we also produce various kinds of horizontal kiln, complete set of cement equipments and free service for assembling various kinds of production line. cement making production line: http://www.china-ore-beneficiation.com/ourgoods/cement_production_line.html
