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.
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.
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 stone crushing plant also called rock crushing plant or stone crusher plant refers to the dedicated device used for the construction sand and stone production.
The sand production line also called the sand making line, sand production plant or sand-making production line is made up of the feeder, jaw crusher, fine crusher, vibrating screen, sand washer, belt conveyor and integrated electronic control device etc.
The magnetic separator enjoys the great freatures of high efficiency, low energy consumption, strong processing capability and strong economical effect, as well as wide application ranges.
