根據河道的環(huán)境不同，一般來說，石子比較少、直徑比較小的河道用自震式比較好，維修方便，節(jié)省動力約3KW。而石子很多，直徑又比較大的河道就要用滾筒式的篩子了。經過篩分后的石子一般直接流入河道，如果有濟價值也可選鐵礦機器由傳送帶輸送到岸上出售；河沙轉入磁選系統(tǒng)。磁選系統(tǒng)主要是磁選機和水洗精選系統(tǒng)。抽沙船選鐵礦機器磁選機的磁表強度一般要達到3800-4500高斯，規(guī)格為750*2200-2400，這樣配套才能達到0%的凈選率。水洗的作用是提高毛鐵粉的品位，一般可在30-45之間自由調節(jié)。尾沙排除系統(tǒng)的作用是將選去鐵粉的尾沙排到遠離本機械的地方，以保證抽沙船機械能正常的工作。一般有自流式、傳送帶式、抽沙船泵式三種形式當然這也是根據河道的具體環(huán)境來定選鐵礦機器的。
According to the environment of the river is different, in general, gravel is relatively small, relatively small diameter of the river with the shock type is relatively good, convenient maintenance, saving power of about 3KW. While many stones, and relatively large diameter of the river must use roller sieve. After screening the gravel in general directly into the river, if the economic value of the optional iron ore machine from the conveyor belt on the sale; river sand into the magnetic separation system. Magnetic separation system is mainly magnetic separator and washing selection system. Pumping sand selected iron machine magnetic separator magnetic strength to achieve general 3800-4500 Gaussian, specifications for the 750 * 2200-2400. So in order to achieve 0% supporting the net election rate. The role of water washing is to improve the grade of the iron powder, the general can be freely adjusted between 30-45. Tail sand exclusion system will choose to iron tailings discharged to the place far away from the machine, to ensure the pumping sand machine normal work. There is general gravity type, transmission belt, pumping sand pump type three kind of forms of course, this is according to the specific environment of the river to selected iron machine. |
