1.2主要特点
Main characteristics
1.2.1 转环立式旋转、反冲精矿。平环强磁磁选机的磁介质堵塞问题是国内外几十年未解决的技术难题。DLS系列磁选机采用转环立式旋转方式，对于每一组磁介质而言，冲洗精矿的方向与给矿方向相反，粗颗粒不必穿过磁介质堆便可冲洗出来，从而有效地防止了磁介质的堵塞。
Vertical ring ration and pulsating beneficiation. Magnetic medium jam of flat high intensity magnetic separator uses vertical ring rotation, the material feeding direction is opposite to the direction of beneficiation for each batch of magnetic medium, thus the coarse granular can be washed away without going through the batch of magnetic medium, the magnetic medium jam is effectively prevented.
1.2.2 设置矿浆高频振动机构，驱动矿浆产生高频振动流体力。在高频脉动流体力的作用下，矿浆中的矿粒始终处于松散状态，可提高磁性精矿的品位。
Equipped with high frequency vibrator, the slurry is driven to generate pulsating hydro-force. Under the action of pulsating hydro-force, the mineral granules in the slurry are always scattered, which improves the efficiency of high intensity magnetic beneficiation.
1.2.3 平环高梯度磁选机对给矿粒度要求比较严格，我们研究了独特磁系结构及优化组合的磁介质，使DLS系列磁选机的给矿粒度上限达到2.0毫米，简化了现场分级作业，使之具有更为广泛的适应性。
Flat ring gradient magnetic separator imposes strict limitation on the fineness of the mineral. We made magnetic medium of unique magnetic system structure and optimized combination, which raises the upper limit of mineral grain- size to 2.0mm, simplifies the work for grading mineral and increased adaptability of the separator.
1.3注意事项

We can design and manufacture special magnetic separators upon specific requirement of customers.
③ 指导用户安装调试设备，并为用户培训操作人员。
We will direct the installation and operation of the equipment, and train operators for customer.
④*冬天设备停机时，应谨防冻裂励磁线圈铜管和整流器内冷却水管路，在可能发生冰冻之前可用压缩空气吹干管路中积水。
In the winter, when the equipment is not used, you should keep the copper pipe of the exciting coils and cooling water pipe of the commutator away from frost. Use the compressed air to blow-dry the main pipe line.
对于吊运中厚板，通常选用MW84或MW04系列起重电磁铁。因为中厚板易于形成磁路饱和，所以MW84系列电磁铁一般设计成多个励磁线圈结构，电磁铁与被吸物形成多个磁回路，从而增加了有效吸附面积，尽可能减少搬运过程中弯曲变形，至于电磁铁的长度主要由钢板宽度确定。
