What Is Grain Slags

Grain Slag is the process of put blast furnace Grain Slag of hot melt state into water for rapid cooling, there are two ways which are blast furnace Grain Slag water quenching or pre-furnace water quenching, is an industrial solid waste, with the continuous improvement of iron production, substantial growth in the amount of Grain Slag produced, causing a lot of accumulation which it is bound to affect the development of enterprises and the social environmental governance.

Usage Of Grain Slag

Slag cement, slag aerated blocks, aerated water with residue brick are all the new application method of grain slag. It is mainly used as below:

1. Slag cement products: Portland blast furnace slag cement, gypsum slag cement, lime slag cement. Lime slag cement can be used for steam curing precast concrete products, water, underground, road and other unreinforced concrete and mortar industry and civil building mud;

2. Produce slag bricks and wet grinding slag concrete products: slag bricks, wet grinding slag concrete, aerated steam-cured brick, aerated concrete blocks, fly ash aerated brick, unburned brick, brick pad;

3. Used for insulation packing: Instead of diatomite used for heat insulation filler, can save cost;

4. The production of slag powder: blast furnace slag can be used for raw material of produce slag powder after grinding by ultra-fine mill, can be used for building materials, roads, chemical, cement, water, brick and other industries.

Grain Slag Powder Processing Technological Process

Phase one: raw material crushing Grain Slag blocks will be crushed to 15mm-50mm fineness by crusher.

Phase two: grinding Grain Slag material will be sent to the storage hopper by the elevator, and than the feeder will send the material to the main mill for grinding.

Phase three: classifying Ground material will be classified, coarse powder will fall back to the main mill to be ground again.

Phase four: production collecting Qualified powder will flow with the air and be collected in the dust catcher, then the finished powder will be transported to the product storage bin through discharge port. Lastly, the powder will be loaded by tank car or packed by packing machine.
