山川浮选机网：磁选机的基本结构及工作原理

磁选机的基本结构
　　
　　湿式永磁筒式磁选机主要由圆筒、辊筒、刷辊、磁系、槽体、传动部分6部分组成。圆筒由2-3mm不锈钢板卷焊成筒，端盖为铸铝件或工件，用不锈钢螺钉和筒相连。电机通过减速机或直接用无极调速电机，带动圆筒、磁辊和刷辊作回转运动。磁系为开放式磁系，装在圆筒内和裸露的全磁。磁块用不锈钢螺栓装在磁轭的底板上，磁轭的轴伸出筒外，轴端固定有拐臂。扳动拐臂可以调整磁系偏角，调整合适后可以用拉杆固定。槽体的工作区域用不锈钢板制造，机架和槽体的其他部分用普通钢材焊接。
　　
　　磁选机的工作原理
　　
　　矿浆经给矿箱流入槽体后，在给矿喷水管的水流作用下，矿粒呈松散状态进入槽体的给矿区。在磁场
　　
　　磁选机的作用，磁性矿粒发生磁聚而形成“磁团”或“磁链”，“磁团”或“磁链”在矿浆中受磁力作用，向磁极运动，而被吸附在圆筒上。由于磁极的极性沿圆筒旋转方向是交替排列的，并且在工作时固定不动，“磁团”或“磁链”在随圆筒旋转时，由于磁极交替而产生磁搅拌现象，被夹杂在“磁团”或“磁链”中的脉石等非磁性矿物在翻动中脱落下来，最终被吸在圆筒表面的“磁团”或“磁莲”即是精矿。精矿随圆筒转到磁系边缘磁力最弱处，在卸矿水管喷出的冲洗水流作用下被卸到精矿槽中，如果是全磁磁辊，卸矿是用刷辊进行的。非磁性或弱磁性矿物被留在矿浆中随矿浆排出槽外，即是尾矿。

Mountains and flotation machine nets: magnetic separators basic structure and working principle

The basic structure of magnetic separators

Wet disposes mainly by permanent magnet separators cylinder, the rollers, brush roller, magnetic department, tub, transmission part 6 parts. Cylinder by 2-3mm stainless steel plate roll welded tube, cover for aluminum parts or components, connected with the stainless steel screw and cylinder. Motor through the reducer or use directly infinitely adjustable-speed motor, driving the cylinder, magnetic roller and brush roller for rotary motion. Magnetic department to open magnetic department, packed in collective cylinder and bare all the magnetic. Magnets with stainless steel bolts into magnetic yoke on the bottom of the shaft, magnetic yoke out the fixed at cylinder shaft turn arm there. Pull (turn arm can adjust, adjust the appropriate PianJiao magnetic department with bars can be fixed. The tub with stainless steel plate manufacturing working area, frame and other parts of the tub with ordinary steel welding.

The working principle of magnetic separation machine

By feed box inflow pulp, after the increment of flow PenShuiGuan for ore under the action of a loose, mineral grains into the tub to state mining area. In magnetic field

The role of magnetic separators, magnetic particles formed magnetic gather happened "magnetic group" or "magnetic chain", "magnetic group" or "magnetic chain" by magnetic effect in in the pulp, poles movement, and to be adsorption in the cylinder. Because the polarity of the cylinder poles along the direction of rotation is arranged alternately, and fixed at work, "magnetic group" or "magnetic chain" with cylinder rotate, the magnetic poles caused alternately due to stir phenomenon, be mingled in the "magnetic group" or "magnetic chain" of the gangue not churn of magnetic minerals, was eventually suck off the surface of the cylinder magnetic group "or" "magnetic Ephraim" is concentrates. Concentrate with cylinder turned to the edge of the magnetic force of weakness, and during discharging water flushing of ore hoses were discharged under the action of the concentrate slot if is the magnetic magnetic roller, unloaded ore is to use brush roller. The magnetic or weak magnetic mineral slurry is left in the pulp from outside with, namely is tailing slot.
