4.1工作原理：
4.1 Operating principle:
DTCXG－ZN50型磁选管是在C形电磁铁的两极之间，装有玻璃管，作往复移动和旋摆。被分选的试样，在通过磁场区域时，磁性物附着于管壁，非磁性物在机械运动中被水冲刷而排出。
DTCXG – ZN50 magnetic tube is between the two poles of C-shape electromagnet and a glass tube is installed as reciprocating and swing. When the sorted sample passes through the magnetic field region, the magnetic substance are attached to the tube wall. The non-magnetic substances are discharged after flushed by water during mechanical movement.
4.2结构简介：
4.2 Structure introduction:
DTCXG－ZN50型磁选管的组成，如图1所示：
Composition of DTCXG – ZN50 magnetic tube is shown in figure 1:
a.支座(8)安装在底座(16)上，用来支撑C形铁芯(4)和激磁绕组(5)。
a. The support (8) is installed on the base plate (16) and used to support C-shape iron core (4) and field winding (5).
b.在铁芯上磁***装有连接环箍(14)，用来连接传动支架(13)。松开环箍上两边螺母，可调节玻璃管安装角度，一般为30度，调整完后，拧紧连接环箍上两边螺母。注意不要拧得过紧，以传动机架不能转动为止。
b. The connection tie hoop (14) is installed at pole end of the iron core and used to connecting the driving support (13). Loosen the nuts at both sides of the tie hoop to adjust the installation angle of the glass tube, which is 30° generally. After adjustment, screw the nuts down at both sides of the tie hoop. Do not tie it over-tightly; it will be suitable if the drive frame can not be turned any more.
c.玻璃管(15)被嵌在铜套(12)中，通过支架架在两磁极之间。用手先拿住玻璃管，松开调节螺栓，可以调节玻璃管位置，调好后拧紧螺栓。
c. The glass tube (15) is embedded in copper sheathing (12) and supported between two poles through a support. Hold the glass tube with hand at first; loosen the adjusting bolt to adjust the position of the glass tube. Screw down the bolt after adjustment.
d.电机通过曲柄使玻璃管作旋摆运动。
d. The motor drives the glass tube to perform swing movement through the crank.
玻璃管与水平线角度调节范围0度～40度。玻璃管行程40mm，旋摆45度。
Regulation range of the angle between the glass tube and the horizontal line is 0°～40°. The glass tube is 40mm in stroke and 45° in swing.
