Precautions of rotary kiln calcining lime

Before drying kiln, it needs to ensure there is enough pulverized coal to be supplied, to ensure the stable operation of rotary kiln, and the uninterrupted flow, as well as the system of rotary kiln heat distribution is balanced. In the process of drying kiln, it also focus on the system and instrument display, such as temperature, pressure, also includes the rotary kiln cylinder of different period of body surface temperature and electric current of the motor and seal. Operators for temperature control, is generally 500 degrees before maintaining temperature at 20 degrees per hour, 500 degrees is controlled at 50 degrees per hour, and will fill in the details of the drying kiln in the note column. Drying kiln, drying kiln temperature curve is very important, are not allowed to make the high or low temperature of drying kiln. In the process, it also notes that refractory drainage condition, when there is abnormal situation, it needs to discuss appropriate adjustment countermeasures together with technical people. Also in the drying kiln process of rotary kiln, staff will do detailed check for the various bearing temperature, drying kiln to finish before production, but also conduct a comprehensive lubrication work inspection, to supplement or replace the parts in time to make changes.Also in the drying kiln process of rotary kiln, staff will do detailed check for the various bearing temperature, drying kiln to finish before production, but also conduct a comprehensive lubrication work inspection, to supplement or replace the parts in time to make changes.
