除铁机分类介绍

作者:管理员     发布于:2017-04-11    

除铁机,又名磁选机。一般指非金属精选磁选机,即去除原材料中的铁质和其他磁性物质,常用于陶瓷、矿业、化工、研磨等行业。例如在矿业中,原料一般先使用大中型的磁选机粗选,粗选后的原料含铁量降低到一定程度,可以供某些对铁含量要求不高的行业使用。而目前,国内外使用的磁选机(除铁机)种类很多,分类方法不一,根据不同特征有以下几种分类方法。

Iron removal machine, also known as magnetic separator. Generally refers to the non-metallic magnetic separator, that is, the removal of raw materials of iron and other magnetic materials, commonly used in ceramics, mining, chemical, grinding and other industries. For example, in the mining industry, the general use of raw materials in large and medium sized magnetic separator roughing, raw material after the iron content to a certain extent, can be used for some iron content requirements of the industry is not high. At present, there are many kinds of magnetic separators (except iron) used at home and abroad, and the classification methods are different.

一、按磁选机(除铁机)的磁源可分为永磁磁选机与电磁磁选机。

First, according to the magnetic separator (iron removal machine) can be divided into permanent magnetic separator and magnetic separator.

二、按选别过程的介质可分为干式磁选机与湿式磁选机。

Two, according to the selection of the process can be divided into medium dry magnetic separator and wet magnetic separator.

三、按磁场类型可分为恒定磁场、脉动磁场和交变磁场磁选机。

Three, according to the type of magnetic field can be divided into constant magnetic field, pulsating magnetic field and alternating magnetic field magnetic separator.

四、按机体外形结构分为带式磁选机、筒式磁选机、辊式磁选机、盘式磁选机、环式磁选机、笼式磁选机和滑轮式磁选机。其中主要以磁场强度、选别介质结构型式来区分。弱磁选机主要用于选别强磁性矿物,如磁铁矿、钛磁铁矿、硅铁。

Four, according to the body structure is divided into belt magnetic separator, drum magnetic separator, roller type magnetic separator, magnetic separator, magnetic separator, magnetic separator and magnetic separator. Among them, the magnetic field intensity and the selective medium structure. Weak magnetic separator is mainly used for the selection of strong magnetic minerals, such as magnetite, ilmenite, ferrosilicon.

五、根据磁场强弱可分为:

Five, according to the strength of the magnetic field can be divided into:

1.弱磁场磁选机,磁极表面磁场强度H0=72~136千安/米,磁场力HgradH=(2.5~5.0)×1011安/米2;

1 weak magnetic field magnetic separator, the magnetic field strength of the magnetic pole H0=72 ~ 136 thousand /, magnetic field force HgradH= (2.5 ~ 5) * 1011 M / m;

2.中磁场磁选机,磁极表面磁场强度H0=160~480千安/米;

2 magnetic field magnetic separator, magnetic pole surface magnetic field strength H0=160 ~ 480 thousand;

3.强磁场磁选机,磁极表面磁场强度H0—480~1600千安/米,磁场力HgradH=(1.5~6.0)×1013安2/米3。

3 strong magnetic field magnetic separator, magnetic pole surface magnetic field strength H0 - 480 ~ ~ 1 million 600 thousand /, magnetic field force HgradH= (1.5 ~ 6) * 1013 m 2/.

经过多年的发展研制出多种形式的湿式强磁选机来适应企业磁选品位低、嵌布粒度细及矿物组成复杂的弱磁性矿物使用,如环式、笼式、圆盘式。中等磁场磁选机(除铁机)主要用来分选局部氧化的强磁性矿石。

After years of development, the development of a variety of forms of wet high intensity magnetic separator to adapt to the low grade magnetic separation, fine grain size and mineral composition of the complex of the use of weak magnetic minerals, such as ring, cage, disc type. Medium magnetic separator (iron removal machine) is mainly used to sort local oxidation of strong magnetic ore.
