Introduction to production process of self-heating vertical decarbonization equipment
Coal gangue is the main solid waste discharged during coal mining and washing processes.Developing efficient decarbonization and activation processes for coal gangue are critical to producing building materials on a large scale and generating considerable economic benefits.Anhui Huaihai New Materials Co.,Ltd has designed a self-heating decarbonization production process based on coal gangue vertical decarbonization equipment,and put it into regular production.This process can achieve decarbonization and activation of coal gangue with particle size of 5~50 mm and different calorific value with no need for additional fuel,and consume 200 000 tons of coal gangue annually.The produced decarbonized coal gangue has superior performance parameters than the requirements of GB/T 2847-2022,and can be used as cement admixture or partially replace cement clinker with broad market prospects.
