Production
The cement enterprises tend to set up their cement clinker grinding plant in the place close to the raw mineral field.Its Production capacity ranges from 200t/d to 8,000t/d.
At present, the ceramsite sand production line as one kind of the light weight aggregate plant or light weight expanded clay aggregate production line tends to adopt the industrial rotary kiln.
Materials are conveyed to the storage bin by the bucket elevator after being crushed by the jaw crusher. The vibrating feeder can deliver the materials to the main engine to be ground continuously and uniformly, and the ground powder is blown to the powder concentrator by the air blower.
Compared with other air flow grinder, mixing grinder and ball mills, this industrial production of slag-powder has doubled productivity which makes it the ideal equipment to produce superfine powder.
The active lime production line, also called quick lime plant, active lime making plant, quick lime line or active lime line, is used to make quality active and quick lime for the modern market.
The flotation separation line is mainly applied to separate copper, zinc, lead, nickel, gold and other non-ferrous metals, and to do rough or fine separation of ferrous metals and non-metals.
