Kiln Product News: ore mining after calcining kiln before to go through some of the post-processing to go through some processing mined ore , lime kiln calcination kiln before firing out of the finished product quality , as well as the color of the limestone from the limestone to analyze impurities in the finished product quality. Lime Kiln finished determinants Judging from the appearance of limestone , limestone color will be more. Common are: gray, gray and black , gray , all red. In general awareness among the excellent physical and chemical properties of limestone, its appearance is generally considered to gray color mainly black . In essence, the low calcium content of the limestone , with the appearance of color is not fundamentally linked. Before or after the mining of raw materials into the kiln firing , usually through the washing process , the purpose is to ensure a clean surface material , reducing the presence of impurities . Potassium impurities wrapped limestone , while the sodium oxide content is small ( < 1% ) , however , have a much lower melting point thereof during the life of an oxide or other compound becomes . Is one of the reasons for the formation of ring kiln . Kiln active oil spray principle , active oil spray perfect to use in a rotary kiln , the structure is composed of a pneumatic pump , nozzle and valve block assembly and other related equipment constituted . In the rotary kiln operation, the solenoid valve is opened so that blowing the situation , when the gas line pressure to a given value, the pressure detection switch will be closed and the pump began to launch operations . Oil from the kiln quantitative dispensing valve to the nozzle , the nozzle atomizing the outer gear sprayed . Rotary kiln reactor delay control function can promote a closed pneumatic solenoid valve lag in the oil , cleaning function is completed , the net residual blowing nozzle , to avoid nozzle clogging . After cleaning suspension , a smooth time segment is completed, the system aborts oil . Setting a good job according to manipulate time segment , the operating time for the next segment , repeat the above process the job .
