The measures to realize the improvement of in-kiln decomposition rate of Rotary Kiln

The following measures can be taken to realize the improvement of in-kiln decomposition rate of Rotary Kiln.
(1) The volume design of the decomposition furnace should take into consideration the flammability of the fuel and make sure that the materials have sufficient staying time inside the furnace. Influenced by the grade and the fineness of the coal powder, the staying time needed by the raw materials and coal powder should be shorted, so is the space needed for independently burning the coal powder.
(2) The volume design of the decomposition furnace should take into consideration the decomposition speed of the raw materials which is not only related to the property of the limestone, but related to the atmosphere inside the decomposition furnace.
(3) When setting the position and number of the material and coal feeding point, it is necessary to consider to reserve sufficient space for the combustion of the fuel before the raw materials are fed into the furnace. Especially for the anthracite that is not combustible, we should also consider the position and direction of the tertiary air induced to make sure that the coal powders are evenly and sufficiently burnt.

The cavity shape of jaw crusher China

The cavity shape of jaw crusher China will directly influence such technical indexes such as productivity, granularity composition, particle size, service life of the crushing plate and electricity consumption. At present, the crushing cavity of large jaw crusher produced in China generally adopts traditional linear type cavity with full tooth. This cavity shape has low productivity, high specific energy consumption, easy blockage, big and uneven product granularity. Recently, Great Wall Machinery has done great research on the crushing cavity and has researched and developed new type of cavity shape to put into production. The practice has shown that when the pendulum stroke and pendulum times of movable jaw are the same, curve type cavity has such advantages as high production capacity, big crushing ratio, even product granularity, low content of over-crushed particles, small abrasion of the lower lining board of the cavity and low specific energy consumption.
The decomposition rate of Rotary Kiln shows the decomposition degree of the carbonate in the raw materials to see whether the equipment design of the preheating and decomposition system is rational and whether the technical parameters are suitable. The kiln decomposition rate is the main index of measuring the normal operation of the decomposition furnace. High decomposition rate means that the role of the decomposition rate has been fully played, for this reason, it is necessary to properly improve the decomposition rate of the rotary kiln.

The working mechanism of jaw crusher

The working mechanism, which is crushing cavity, of jaw crusher is formed by a fixed jaw and a mobile jaw. On both jaw plates, there are lining boards made of manganese steel and they are fixed onto the jaw plate with bolts and wedge. As lining boards directly participate in the crushing process, to improve the crushing effect, on the surface of the lining boards, there are horizontal ripples which are set opposite each other in lumps and bumps. At present, the tooth form of jaw crusher China is triangle or trapezoid on which there are vertical bars. With the application and development of computer technology, the design of tooth form has developed from traditional test method and experience method to applying computer for optimized design, thus gaining optimum crushing effect.
As the abrasion of all the parts of the lining boards in the crushing process is pretty uneven, especially that bottom part near the discharging mouth, lining board is usually made transversely zygomophic, so that it can be reused reversely after the lower part is abraded to extend its service life which is a little different from cone crusher. The lining boards of large jaw crusher China are composed of many blocks which are all interchangeable; with the purpose of prolong its service life.
