Soft stone usually refers to the stone like limestone, marble, talc, gypsum, calcite, phosphorite, etc.
The classic production line for the soft stone is JAW CRUSHER (primary crusher) + IMPACT CRUSHER (secondary crusher), and with the auxiliaries of vibrating feeder, vibrating screen & belt conveyors.
Regarding of the detail condition, two kinds of techniques are usually adopted in producing manufactured sand, dry way and wet way. Both methods can produce high quality manufactured sand as concrete aggregate. Especially, the dry way can produce not only the manufactured sand used in SMA road surface, but also the powder used in asphalt concrete.

2012-09-30 To beneficiate low-grade ore, it is first pulverized into finer particles called pulverized ore. Both fine and pulverized ores are then subjected to pre-treatments before they are charged into the BF; that is, the fine ore is processed into sintered ore by sintering, and pulverized ore is processed into pellets by pelletizing.
Theory and Practice of Sintering of Iron ore. Sintering of iron ore is a generic term which is used to describe the process whereby a sinter mix (raw mix or green mix) of iron ore fines, fluxes, fuel (coke breeze) and plant return fines (e.g. mill scale, blast furnace dust, and returned sinter fines etc.) are converted into a particular form of ...

Iron Ore Sintering Furnace Wholesale, Furnace Suppliers . Pig iron blast furnace steel blast furnace 1. THE TASK OF BLAST FURNAC IRONMAKING The task of blast furnace is to use reducing agent (coke, coal, etc) to turn iron ore or ferrous materials into liquid pig iron under high temperature.
Iron ore is typically characterized chemically, physically, and mineralogically. The effect of iron ore characteristics on sintering is mainly through their impact on the granulation and densification processes. With the rapid change in iron ore supplies and composition, steel mills now have to adjust the composition of the ore mixture to their ...
Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. In this chapter, the sintering process is first described and the key steps of the sintering process, namely, granulation and thermal densification, are identified.

portion of −20 ˚m in iron ore concentrate favoured the granulation and the productivity in conventional sintering, but the portion of +45 ˚m had the reverse effects. With increases in finer commercial concentrates (10–40 mass%) combined with low grade ore (10–20 mass%) in iron ore blends, the productivity also did not obviously change.
