How to get high quality coal dust for lime calcination?What you get on the market is generally finished coal, and to get coal dust suitable for lime calcination, use Henan LBY Heavy Industry LM Vertical Mill.Since its establishment, Henan LBY Heavy Industry has obtained 21 patents, has 14 product certificates and has won 13 corporate awards.Among them, on September 12, 2022 was awarded the name of “National Green Factory”, both the brand and the product are the first choice of coal powder for lime calcination.
Lime calcination is generally divided into combustion system, lime rotary kiln main body, raw material screening system, wind system and dust removal and environmental protection system.The coal briquettes for combustion in the first part of the combustion system require the use of LM Vertical Mill in order to obtain pulverized coal.The pulverized coal for lime calcination needs to meet the safety requirements for ash, volatile matter and moisture before it can be burned.Low melting point compounds can cause sticking and ringing in the kiln, which can corrode the kiln lining and lead to lower product yields.The value of the volatile fraction needs to be maintained between 32% and 38%, because too high a volatile fraction can explode and create a hazard.If the moisture content is too high, the combustibility of the pulverized coal will be reduced, affecting the fuel consumption.Only Henan LBY Heavy Industry LM Vertical Mill can meet the high requirements for ash, volatile matter and moisture of pulverized coal at the same time.
Henan LBY Heavy Industry’s design and development department has developed 27 types of targeted LM Vertical Mill specifically for the non-metallic ore, coal dust and slag industries.LM Vertical Mill perfectly combines crushing, drying, grinding, classifying and conveying into one, with compact layout design and small footprint.LM internal grinding rollers are directly on the grinding disc to grind the material, and the grinding rollers are equipped with grinding roller sleeves, which can effectively reduce energy consumption and extend the service life.The LM uses hydraulic pressurization to increase the grinding force and the LM powder separator uses cage and conical rotors to increase the output and improve the precision of powder separation.
