2. Design of Slag Grinding Production Line Gypsum, dry slag and pulverized coal are measured by the belt weigher before mixed together according to particular proportions. Mixed materials will be sent to the mill for grinding, and during this process, iron remover is employed to remove magnetic metals in these materials.
Grinding The first step of the grinding process requires the slag to be dried down to about 2.5% moisture. These dried granules are then pre-ground with two high to the ball mill, a large tube 15 feet in diameter and 50 feet long partially filled with small steel balls, which further grind the material to ASTM C989 and AASHTO Get Price

The slag is transported by the elevator into the vertical mill for grinding. The slag powder is then collected by the powder separator and dried using a hot blast stove. The dried slag powder is transported into the vertical mill for regrinding, after which the slag powder will be collected using a powder separator.
The hot air used for drying is supplied with a hot wind generator. Slag contains iron grain, which could damage the rotating table and aggravate grinding efficiency. Hence, the removal of these iron grains before commencing the grinding process, using an external circulation system with a magnetic-separator device, is crucial.
Granulated Blast Furnace Slag (GBFS) contains a high level of moisture, it is hard to grind and very abrasive. 2 Natural pozzolans may not be as hard to grind as GBFS but may contain high moisture levels and be abrasive. 2 Both of these materials require grinding systems designed to deal with high moisture, hardness and abrasiveness.

Abrasive blasting materials, such as coal slag garnet and copper slag, are often used for cleaning metal surfaces to remove rust and to prepare a surface before the application of a coating. The pre-blast and post-blast (spent) abrasive materials contain traces of heavy metal constituents such as Cr, Mn, Ni, Pb Fe, and Ba.
In recent years, the grinding of special materials such as slag fine powder, slag, and water slag has received more and more attention. Taking slag as an example, concrete mixed with fine slag powder significantly improves and improves the comprehensive performance of concrete, and wins good economic benefits for customers.
New slag drier is not just for the sake of drying, but for improving the grinding efficiency and production efficiency, thus gaining more benefits. Slag is definitely use its own activity. If the temperature is too high, the activity will be destroyed, which will finally affect the customer's long-term, potential, and the fundamental interests.
