摘要: Apparatus in which cement clinker is crushed at a temperature of 1,000* to 1,450* C., is then brought, while passing through a reducing atmosphere for between 1.5 and 6 minutes, down to a temperature in the range 700* to 1,100* C., is then subjected to rapid cooling by the application of atomized water to reduce the temperature to approximately 300* C. while excluding oxygen, and is finally collected in free air, thorough contact with the reducing atmosphere and the subsequent rapid cooling being ensured by carrying out these stages while the clinker is vibrated down an incline from the exit of the crusher to its point of collection in the atmosphere.
