试验室XCRS400×300型鼓形湿法弱磁场磁选机技术参数
Technical Parameters of Laboratory Drum Wet Low-intensity Magnetic Separator

XCRS型湿式磁选机主要应用于金属选矿实验室。它利用湿式方法对细粒强磁性矿石进行磁选，选别形式为顺流式。磁选机体积小、重量轻，操作简单、维护方便。该设备不宜进行带有腐蚀性液体的选矿试验。本产品由原地矿部唯一指定企业生产，执行行业标准。

鼓形磁选机转鼓内装开式磁系，当给矿时能迅速地分选出磁性矿物，磁性矿物在槽中被磁力吸在鼓面上，受磁力搅拌下甩掉污泥，最后随鼓面旋转借助于冲水排出机外。

XCRS Wet Magnetic Separator is mainly designed for labs for metallic mineral processing. It conducts concurrent magnetic separation of fine-grain ores with strong magnetism by use of Wet Method. It is small in volume, light in weight, simple in operation and convenient in maintenance. However, it is unsuitable to be used in beneficiation tests with corrosive liquors. The product is produced by the only enterprise designated by the former Ministry of Geology and Mineral Resources, in compliance with the Industrial standards.

Drum Magnetic Separator is provided with an open magnetic system in its rotary drum to rapidly separate magnetic minerals, which will be absorbed by magnetic force on the surface of drum and threw off sludge in agitation by magnetic force before being washed out of the separator with the help of rotation of drum surface.

XCQS型湿式磁选机是由磁选机主体及鼓形电源两部分所组成。磁选机主体主要包括：（1）机架（2）磁鼓（3）矿槽（4）喷水管（5）传动装置（6）给矿箱

XCQS wet magnetic separator consists of two parts, the main body and drum power supply. The main body the magnetic separator mainly includes: (1) frame (2) magnetic drum (3) ore tank (4) spray pipe (5) transmission device (6) feed tank.

鼓形电源为一单独的硅桥式整流电源、其输出是通过调压器手柄进行调整的。

The drum power supply is a separate silicon bridge rectified power source whose output is adjusted through the handle of voltage regulator.

1、机架：由角钢焊制，为整个机器的支承部分。

1. Frame: The frame is welded by angle iron. It is the supporting part of the whole machine.

2、磁鼓：内装有四个激磁线圈及磁铁芯，并在其排矿侧装有一个没有激磁线圈的附加磁极，以利于卸矿，这五个在磁极形成扇形固定在心轴上，心轴通过支轴承瓦固定在机架上，圆筒系用非磁性材料铝及不锈钢制成，扇形线圈的连接以造成在每磁极掌上磁场极性的交变、矿粒每通过一个磁极即翻转达180度，在磁搅拌的作用下，可以改善磁性产品的质量。在心轴的一端，为方形的外伸结构，可以用手板，使磁鼓内磁极绕轴向旋转，以适应不同矿种的选别需要。

2. Magnetic drum: Four excitation coils and magnetic cores are installed inside the magnetic drum. Besides, an interpole is without excitation coil is installed at the side of the magnetic drum along which the ore is discharged, to facilitate the discharging of ores. These form a sector and are fixed on the mandrel. The mandrel is fixed on the frame through bearing bushing. The drum is made of non-magnetic aluminum and stainless steel. The connection of sector coil causes the alternation of magnetic field polarity on every magnetic pole palm. The ore grains turn 180°each time it passes one magnetic pole. Under the action of magnetic stirring, the quality of magnetic products can be improved. At one end of the mandrel is square extension structure which can be pulled by hand, to get the magnetic pole in the magnetic drum to rotate axially so that it can meet the requirements for the sorting of different ore types.

3、传动装置：安装在机架的底部一侧，为了降低整机的重心，传动部分由三项交流电动机及蜗轮、蜗杆变速箱所组成，变速箱的输出通过链条传动至磁鼓，带动磁鼓旋转（磁极是不随之转动的），磁鼓的转速为恒转速25转/分，磁鼓旋转力方向与给矿方向一致。

3. Transmission device: The transmission device is installed at one side of the bottom of the frame. To lower the center of gravity of the machine, the transmission part is composed of three phase alternating current motor, worm gear and worm gear box. The output of gear box is transmitted to the magnetic drum through chains, to drive the rotation of magnetic drum (the magnetic pole does not rotate with it). The magnetic drum rotates at a constant speed of 25 R/min. The direction of rotary force of the magnetic drum is consistent with the direction of ore feeding.

4、矿槽：

4. Feed Tank

由铝及不锈钢板焊制而成，用螺丝固定在机架上；在矿槽的给矿侧设有保持液面高度的溢留口，在排精矿槽体下部设有接精矿嘴以便接矿。

The feed tank is welded by aluminum and stainless steel plate. It is fixed on the frame with screws. An overflow mouth to keep the liquid level is set at the side of feed tank along which ores are fed. Concentrate feeding mouth is set at the bottom of the concentrate discharging tank to receive ores.

5、喷水管：

5. Spray Pipe

安装在机架上的一根带孔铜管，与室内水源相接，用于磁鼓上精矿的冲洗；喷水角度可以通过旋转喷水管进行调节。

A copper pipe with hole installed on the frame is connected to the indoor water source and is used to wash the concentrate on the magnetic drum. The spray angle can be adjusted through the rotation of spray pipe.

6、给矿箱：

6. Feed Tank

箱体由不锈钢板焊接而成，其作用是保证给矿时的均匀性。

The feed tank is welded by stainless steel plate which is used to ensure the homogeneity during material feeding.
