Lime Slaking Technology

The technological aspects of lime extinguishing in bladed two and three-section devices are considered. The main characteristics of the devices for extinguishing lime are given - performance, water consumption, electricity, quantity and composition of waste gases. Presented the scheme and characteristics of the mobile hydrator, the performance of 1 t/hour. Options for extinguishing ground and crushed lime are presented. It is shown that when the crushed lime is extinguished of low quality, it is possible to improve the quality of hydrateed lime by removing unextinguished grains on the rumble, whiz or air classifier. A comparative analysis of the various lime extinguishing schemes was carried out: extinguishing of ground lime, extinguishing crushed lime with a rumble and a mill, extinguishing crushed lime with an air classifier. Thus, when lime is extinguished in the blade, it is possible to obtain hydrated lime of the 1st and 2nd grade from both ground and crushed burnt lime. With crushed lime, it is possible to improve the quality of hydrateed lime, but the extinguishing scheme is complicated and formed up to 20% of solid waste.
