Praha is a leader in the mining industry, mainly with sand and gravel equipment, milling equipment, mineral processing equipment, building materials equipment, etc..
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.
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.
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.
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.
Compared with the simple one, the dry mix mortar plant is more advanced because the materials can be packed automatically by the valve pocket packing machine or the open pocket packing machine after being mixed.
