With shaft preheater kiln, the material is preheated in the preheater tower that carried the material into the rotary kiln is calcium carbonate decomposition zone,

meanwhile, in order to play preheater kiln production potential, while maintaining a reasonable Preheat the thickness of the case for greater reference speed rotary

kiln, kiln quicker, and you must lengthen the firing zone, so that the material in the firing zone stay as long as necessary, for the above reasons, with shaft preheater

rotary kiln burning zone generally higher than long hollow rotary kiln burning zone, raw materials, "shadow" far away from the kiln, difficult to see, therefore, with a

shaft preheater kiln, the judge burning zone temperature mainly to see the flame color, skin color kiln, firing and cooling with material lifting height with clinker

particle-based, while watching the raw materials, "shadow" position supplement. Shaft preheater kiln and working conditions, mainly based kiln exhaust gas

temperature, exhaust gas temperature and exit cyclone outlet cyclone vacuum to judge. Same with cyclone preheater kiln, rotary kiln exhaust gas temperature level,

on the one hand depends on the kiln calcination conditions, on the other depending on shaft preheater heat exchange needs. Kiln exhaust gas temperature

fluctuation is smaller, kiln thermal system more stable. Vertical tube exports and cyclone outlet exhaust gas temperature is to determine shaft preheater working

conditions and heat consumption of clinker size of the main parameters. Li opposing cylinder barrel volume of feed exports and cyclone outlet exhaust gas

temperature is very sensitive to the impact of changes. If the feeding tube quantity reduction legislation, the vertical tube and cyclone exhaust gas temperature will

rise, if the vertical tube cutting, vertical tube exports and cyclone outlet exhaust gas temperature will suddenly rise, cyclone vacuum outlet but also to determine

working conditions and cyclone kiln main parameters of ventilation systems must be closely monitored in the cyclone cone cyclone parts should be installed to

monitor congestion instrument (such as a table or r-rays negative level meter, etc.) in order to cyclone began clogging timely signaled that can timely manner. The
