Aggregate Crushing Plant

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.

Sand Making Plant

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.
