By negasyascheysya of lime are also decomposed by roasting limestone, perezhzhennye oxide particles of calcium and magnesium salts, vitrified tumors, resulting in peresypnyh furnaces in the interaction of lime and ash fuel. The longer the process takes place covers, the more high-quality product is obtained. In industrial-scale suppression is mechanized. The choice of scheme depends on what product to get – "hydrated lime," or lime putty. Most of the lime in pushonku extinguished. Quenching in a hydrator pushonku produce periodic or continuous. By periodically operating hydrator include cylindrical or drum gasilnye barrel-shaped with a capacity of about 15 meters.
Drums with a speed of 3 to 5 rev / min. set horizontally on rollers. In the pre-loaded drums crushed in hammer or cone crushers with lime size pieces 3 – 5 mm. Lime is quenched with steam coming through paropodvodyaschee device. The duration of suppression, including loading and unloading of the product is 30 – 40 min. After dropping particles of lime neprogasivshihsya sent to the bin or silo for staying (silage), where the process of extinction continues, which leads to higher quality material. Setting-up "pushonki" compared to the production of lump lime has several advantages: neprogasivshiesya particles are separated at the factory, transportation convenient packaged pushonki, such a product has a longer storage period. However, the cost pushonki higher since its release requires the organization of hydrated and packaging plant site. The process of clearing the dough is more durable and complex. It applies if the lime is designed for use at the production site or at sites in the vicinity (Such as a mortar).
