The extracted bauxite generally has a block size of around 300-500mm and contains a small amount of moisture. Generally, a secondary crushing system consisting of jaw crushers and hammer crushers is used to control the particle size to ≤ 8mm. After entering the factory, the bauxite can be stacked separately according to the different ridge positions of the product. Use according to the indicators when using. Manganese (Mn) element is usually added during the production of ceramic sand to lower the sintering temperature and dye the product dark. At present, most domestic manufacturers use low-grade (content~50%) manganese ore or manganese ash as the source of manganese element. Generally, a ball mill that combines drying and grinding is used, accompanied by an efficient powder selector, to form a closed-loop system. This way, the efficiency of grinding is high. The hot air for drying materials can come from the waste gas of the rotary kiln for waste heat utilization; Special hot air stoves can also be set up. The raw material powder produced by grinding is stored in the raw material warehouse. Generally, 2-3 warehouses are set up, which can be used for separate discharge or multiple warehouses can be used for combined discharge. The raw material powder is fed into a small silo, and a spiral measuring device or a speed regulating belt scale device is installed under the silo to measure the amount of raw material. The raw material enters the disc ball making machine. At the same time, a flow meter can be used to measure the amount of water, which is sprayed into the disc ball making machine by a pipeline pump. During the rotation process of the ball making mach

ine, various particle sizes of material balls can be produced. After the material balls are discharged from the tray, they are sent to the screening device by the belt conveyor. The qualified ones enter the rotary kiln, and the larger ones return to the raw material grinding process. Different numbers of disc ball making machines can be equipped according to the output of different kilns. The ball making system has a high degree of automation and continuous process. After being equipped with a bag filter, it can achieve the standard of post dust and purify the working environment of the post. The material ball enters a rotary kiln with a certain slope for calcination. As the rotary kiln rotates, the material ball rolls towards the kiln head, and at the same time, coal powder is sprayed into the kiln from the kiln head for combustion. The material ball is calcined into high-strength ceramic sand in the rotary kiln. The coal powder burner can use a single air duct coal injection pipe, which is simple, reliable, and has a high primary air volume; Multi duct burners can also be used, which can reduce the primary air volume to 8% of the required air volume for coal powder combustion, increasing the secondary air volume entering the kiln and achieving significant energy-saving effects. Multi duct burners are divided into external axial flow air, coal air, internal axial flow air, etc., and the flame shape is very easy to adjust. The measurement of coal powder can be carried out using rotor type measuring scales or Coriolis force scales to accurately control the coal quantity and stabilize the thermal system inside the kiln. The ceramic sand from the cooling machine can be directly transported to a multi-stage vibrating screen
