Introduction

除铁器分为永磁除铁器和电磁除铁器，一般与皮带输送机或者给料机配套使用，有时也与管道连接使用。如何根据不同的物料，不同的生产环境选择最佳的除铁设备，也是大家咨询较多的问题。今天我们就重点介绍一下与皮带输送机配套使用的选型方法。

The iron remover is divided into permanent magnet iron remover and electromagnetic iron remover, which is usually used with belt conveyor or feeder, and sometimes used with pipes. How to choose the best iron removal equipment according to different materials and different production environment is also a problem that everybody consulted more. Today, we will focus on the selection of the matching method with the belt conveyor.

除铁器选型时要注意什么呢？下面几点不可忽视：

What should be paid attention to when the iron is selected? The following points should not be ignored.

用户在选用除铁器时，必须先考虑的是输送胶带的带宽、带速、倾角，物料的性质、湿度、粒度、厚度，物料中的含铁量的多少、铁磁物的粒度、性质，除铁要求、使用环境（温度、湿度、粉尘、有无腐蚀性等）、除铁器本身的特性，安装的位置、空间等。

The user in the selection of separators, we must first consider the conveyor belt width, belt speed, angle, nature, humidity, particle size, thickness of material, material containing iron amount, particle size, magnetic properties of iron, iron requirements, use of the environment (temperature, humidity, dust, there is no in addition, corrosion resistance and other properties of the iron itself), location, space etc..

当物料中含铁量较多时，应选用连续自动除铁的自卸式电磁除铁器（如市场上的RCDC、RCDD、RCDF系列），自卸式永磁除铁器（如RCYC、RCYD系列），永磁滚筒（如RCT系列），电磁滚筒（如CFDL系列）。

When the number of iron containing material in amount, should choose continuous automatic removal of iron dump type electromagnetic separator (such as the market RCDC, RCDD, RCDF Series), dump type permanent magnetic separators (such as RCYC, RCYD Series), permanent magnet drum (RCT Series), magnetic drum (such as CFDL).

当物料中含铁量较少时，应选用永磁除铁器（如市场上的RCYB系列），电磁除铁器（如RCDA、RCDB、RCDE、CF系列）。

When there is less iron in the material, the permanent magnet iron remover (such as the RCYB Series in the market) and the electromagnetic iron remover (such as RCDA, RCDB, RCDE, CF Series) should be selected.

当物料中的铁磁物特别少时，选用金属探测仪和强磁自卸式电、永磁除铁器配套使用，达到自动监测自动除铁，具有省电节能、寿命长、除铁效果好等特点。

When the ferromagnetic material in the material is very few, the metal detector and the strong magnetic self discharging electric and permanent magnet iron remover are used together to achieve automatic monitoring and automatic iron removal. It has the characteristics of electricity saving, energy saving, long service life and good iron removal.

当使用悬挂式电、永磁除铁器时，如物料过厚可与无磁托辊配套使用，提高除净率，也可适当降低悬挂高度，以达到理想的除铁效果。

When hanging electric and permanent magnetic iron remover is used, if the material is too thick, it can be matched with the magnetic idler, improve the net removal rate, and also reduce the suspension height, so as to achieve the ideal iron removal effect.

当使用环境（如粉尘、烟尘、灰尘）较严重时，应选用全密封结构的电磁除铁器、永磁除铁器。

When the use of the environment (such as dust, dust, dust) is more serious, a fully sealed structure of electromagnetic iron remover and permanent magnet iron remover should be selected.

当物料中含有除铁器不能吸附的非磁性金属材料时，应选用金属探测仪检测出金属物，自动停机报警后人工除铁。

When the material contains non-magnetic metal material that can not be adsorbed by iron, the metal detector should be used to detect metal objects, and automatically shut down and alarm, then remove iron manually.

当用户不使用输送胶带而采用溜槽、管道、链板机、提升机等设备输送物料时，应采用管道式永磁除铁器。

When the users do not use the conveyor belt and use the chute, pipe, chain board machine, elevator and other equipment to transport materials, the pipe type permanent magnet iron remover should be used.

对于除铁要求较高的场合，如要求悬挂高度大于额定悬挂高度，或物料厚度大于额定厚度时，应选用大于本规格的除铁器或采用多级除铁。

For occasions requiring high iron removal, for example, if the required suspension height is higher than the rated suspension height or the material thickness is greater than the rated thickness, the iron remover larger than this specification or multi-stage iron removal shall be
