When stacking in tunnel kiln, no matter what form of stack is stacked, it is necessary to let the air flow pass through the middle of the stack or the hole of the brick as much as possible. The side gap should be minimized, the effective heat transfer area of the stack should be increased, and the heat transfer route should be shortened. This method is not only conducive to preheating and roasting, but also conducive to cooling. Different forms of billet stacking have a great impact on the air flow distribution on the cross-section of the whole kiln. For example, the measurement in one place has proved that when the edge gap of the kiln is more than 15 cm, only 5% of the air flow can pass through the middle of the billet stack, while 95% of the air flow flows from the edge gap and around the billet stack. Chongqing Building Materials Design and Research Institute has done billet stacking mining

Recently, some customers of the hydraulic lifting clamp and brick separator reported that the pressure was very stable in the morning, but the pressure could not rise at noon. From the northwest to the southeast, some customers had encountered such a situation. According to the experience of solving problems later, there was no case of such phenomenon caused by the failure of the overflow valve or the pressure relief of the oil cylinder. The temperature difference between day and night in northwest China is large. In southeast China, this phenomenon is easy to occur when the temperature rises in the beginning of spring. The pressure cannot rise naturally to affect the brick clamping, thus affecting production. In fact, the reason for this phenomenon can be seen from the above description, which is related to the temperature and season, and the temperature has a great impact on the mechanical circuit and valve block

It is composed of several brick burning caves and a huge smoke chimney. The temperature in the cave is quite high, about a thousand degrees. The main location of the kiln is above the cave, and the location of the earth bricks is in the cave. The material of the kiln is basically coal. Brick kilns can generally be divided into the following categories: rotary kilns rotary kilns refer to rotary calcining kilns (commonly known as rotary kilns), which belong to building materials equipment. Rotary kilns can be divided into cement kilns, metallurgical and chemical kilns and lime kilns according to different materials. Cement kilns are mainly used to calcine cement clinker, which can be divided into two categories: dry production kilns and wet production kilns. Metallurgical chemical kilns are mainly used for magnetization roasting of lean iron ores in metallurgical steel plants
