The particle size of anthracite or coke is required to be below 50mm, the low-melting ash content is not excessive, and the addition amount of the anthracite or coke is 7.5-8.5% of the weight of the limestone. The screened limestone and fuel are added into the kiln from the kiln top at fixed time and fixed quantity, calcined at 900-1200 ℃ and cooled to obtain the finished product, and in addition, the shaft kiln is the thermal equipment for continuously calcining clinker by feeding from the upper part and discharging from the lower part. Consists of a kiln body, a feeding and discharging device, ventilation equipment and the like. The method is widely used for calcining various refractory raw materials and lime, and has the advantages of less investment in capital construction, less occupied area, high efficiency of cooking, low fuel consumption and easy preparation and automation.
It is generally necessary to weigh anthracite and limestone by a feeding system and then transport them to a feed inlet of a shaft kiln, then pour the mixture of anthracite and limestone into the interior of the shaft kiln, and fire the mixture by using a high temperature in the interior of the shaft kiln, but generally the anthracite and limestone are not completely mixed but are stacked on each other after weighing, so that when the mixture is poured into the interior of the shaft kiln, if the anthracite and limestone are insufficiently mixed, the limestone firing efficiency is reduced, the feeding system is fixed for a single time, and the shaft kiln needs to add the mixture according to the firing condition in the furnace, so that the design of a storage space and a controlled discharge amount is lacking at the top end of the shaft kiln.
