利用給礦(kuang)高差產(chan)生的(de)(de)(de)壓(ya)力(li)(li)(li)使(shi)礦(kuang)漿(jiang)從(cong)給礦(kuang)管(guan)以切線方向(xiang)進入(ru)機(ji)內，通過強(qiang)壓(ya)穩(wen)流環，迫使(shi)礦(kuang)漿(jiang)作(zuo)旋(xuan)轉(zhuan)(zhuan)運動，產(chan)生較強(qiang)的(de)(de)(de)旋(xuan)轉(zhuan)(zhuan)流，離心力(li)(li)(li)、摩擦阻力(li)(li)(li)。當旋(xuan)轉(zhuan)(zhuan)流往下(xia)運動到底盤時，金(jin)粒首先進入(ru)底盤的(de)(de)(de)漸開(kai)線和螺旋(xuan)線溝槽內，隨著(zhu)旋(xuan)轉(zhuan)(zhuan)礦(kuang)漿(jiang)的(de)(de)(de)帶動，金(jin)粒和重礦(kuang)物沿溝槽底端(duan)中心流動，聚集在(zai)底端(duan)平面上并(bing)從(cong)精礦(kuang)管(guan)排出。尾(wei)礦(kuang)在(zai)軸向(xiang)力(li)(li)(li)的(de)(de)(de)作(zuo)用下(xia)從(cong)溢(yi)流管(guan)排出腔外(wai)。該設(she)備對礦(kuang)漿(jiang)濃度及給礦(kuang)壓(ya)力(li)(li)(li)變化適應(ying)性(xing)強(qiang)，不需動力(li)(li)(li)，與(yu)其他(ta)設(she)備比較對細粒金(jin)分選效(xiao)果好。

The pulp delivered form feed pipeline flows into the sweepwasher in the direction of tangent line via the pressure pro-duced by difference in height of feed pulp level.The pulp is forced to do rotary motion via barretter with strong pressure.The motion produces strong rotary flow,centrifugal force and frictional force.When the rotary flow moves downward to the bottom disk,gold grain will firstly enter into the ditch of involute and helix on the bottom disk.Gold grain and heavy minerals will flow along the bottom center of ditch with the motion of spiral pulp.They will be concentrated on the flat surface of the bottom and be discharged by concentrate pipeline.The tailings sand will be discharged by overflow pipeline under the action of axial force.The equipment has good adaptability to the change of pulp concentration and feed pressure.Power is unde-sirable in the equipment.Compared with other equipment,the equipment has good beneficiation effect on fine-grain gold.

注：機器采用內襯耐(nai)納特橡膠或(huo)玻璃鋼、聚氨脂(zhi)制造(zao)，耐(nai)磨防(fang)腐(fu)。

Remark:The equipment is manufactured by using LINATEX rubber or glass fiber reinforced plastics as interna lining with the properties of anti-friction and anti-corrosion.
