Praha is a leader in the mining industry, mainly with sand and gravel equipment, milling equipment, mineral processing equipment, building materials equipment, etc..
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.
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 ore processing plant is divided to copper ore processing plant, iron ore processing plant, tin ore processing plant, magnetite iron ore beneficiation line and chrome ore beneficiation plant etc.
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.
