Preheater with calciner and rotary kiln, rotary kiln is between the preheater and calciner add another one, it will be divided into three stages of clinker formation process, each of the three devices, namely raw materials In preheater preheating and drying is carried out most of the raw material decomposition in the decomposition furnace, while clinker burning and partial cooling is carried out in a rotary kiln. The calcined clinker to add 50-60% of the total fuel decomposition furnace, the fuel in the decomposition furnace raw materials intimately mixed with the fuel combustion process and the endothermic decomposition of the raw material in the suspension process, is carried out under very rapidly, raw material in the kiln feed has been 85-95% when the decomposition of calcium carbonate, calcium carbonate decomposition rate as high into the kiln, thus making the production can be significantly improved, while the size of the kiln and fuel consumption remain unchanged , the decomposition rate is higher the higher the yield. Decomposition kiln new technology has the following significant advantages: 1, high yield per unit volume of the kiln, the suspension preheater kiln with 2-2.5 times, i.e. in the kiln under the same specification, the output ratio with suspension preheater kiln 1-1.5 times as high. 2, due to high yield per unit volume of the kiln, and thus small kiln, carbonate decomposition with about half the length of the dry kilns are moved to the kiln, kiln length so short, small footprint, easier to manufacture and install , infrastructure investment decreased.
