Magnetic Separation Process Flow and Equipments Introduction

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) January 10, 2012 -- Magnetic separation: based on magnetic differences between mineral,Primary jaw crusher uneven in magnetic field between the mineral separation realize a mineral processing. At present, the use of magnetic separation machine type many different classification method.
(l) according to the magnetic separation machine magnetic source can be divided into permanent magnetic separation machine and electromagnetic magnetic separation machine

(2) according to the magnetic field strength can be divided into: weak magnetic field intensity magnetic separation machine, magnetic separation machine in magnetic field, strong magnetic field intensity magnetic separation machine
(3) according to choose the process can be divided into the media don't dry magnetic separation machine and wet magnetic separation machine
(4) according to the magnetic field types can be divided into constant magnetic field, pulse magnetic field and alternating magnetic field intensity magnetic separation machine;

(5) according to the body shape structure is divided into belt magnetic separation machine, magnetic separation machine,Iron ore concentrator roller of cavitation magnetic separation machine, magnetic separation machine, ring type disc magnetic separation machine, magnetic separation machine and slide cage type wheel magnetic separation machine.
1. The magnetic separation technology application
Usage: black metallic ore dressing-iron ore magnetic separation; Non-ferrous metal and rare selected-tungsten tin separation, copper molybdenum separation, copper lead separation;Ball mills Heavy medium in the heavy medium magnetic dressing the magnetic separation recycling; Raw material processing non-metallic minerals from the iron impurity, kaolin except iron; Wastewater treatment.
(1) of the magnetite weak magnetic separation

Our country anshan iron company big GuShan iron ore to deal with poor magnetite anshan type, undressed ore iron content 30% ~ 40%, 42% ~ 46% sio2 content. The principle of the process for stage grinding stage choose don't flow, choose don't equipment is permanent magnet type magnetic force to take off the mud slots and permanent magnet tube type magnetic separation machine.
(2) the hematite, mirror of iron ore,Flotation cells siderite reduction roasting-low intensity magnetic separation, strong magnetic separation used for ferromanganese ore, black tungsten rough concentrate and zirconium, rough concentrate stones, titanium iron ore, coal and high territory.VSI sand maker
2. Electricity choose process

Electricity is different with the selected mineral materials and charge under the action of electric field outside the separation happened as the theoretical basis. The application of the inherent material choose different friction properties, electric conductivity and charged dielectric properties. Because the electrostatic force and granular surface charge is proportional to the size and strength of electric field, so electrostatic force, and slice of fine for the light particles affect larger. Therefore, particles can get effective separation.
The industrial application of choose process can be divided into several categories:
1) minerals and coal separation (concentration and choose coal department);
2) food purification (food);
3) waste disposal (waste management);Drum dryer
4) electrostatic classification (according to grain size and shape will solid classification);
5) electrostatic deposition (removed from solid granular material or from gas pollution from the liquid).
3. Magnetic separation equipment
(1) the wet weak magnetic field magnetic separation machine permanent magnet cylinder

This kind of magnetic separation machine is mainly used for sorting strong magnetic materials.
(2) electromagnetic magnetic pulley
The equipment running direction along the material or polarity of the single polarity alternating magnetic multipole the composition. Electromagnetic induction intensity of magnetic pulley can be up to 0.1 ~ 0.15 T, feed size 10 to 100 mm. The size of the block for ￠L (600 ~ 1000) (1700 ~ 2400) mm. It in the role and permanent magnet concentrator magnetic pulley the same.
(3) permanent magnet tube type magnetic separation machine

Equipment structure: it by the main part of the cylinder and the magnetic is formed.Spiral classifier price Magnetic system and magnetic field characteristics: magnetic ferrite are sr. Application: fine grain of strong magnetic mineral grains of dry choose, magnetic materials of purification, powder material eliminate magnetic impurities.
(4) the wet weak magnetic magnetic separation machine
The equipment is, tub magnetic cylinder, such three main parts.
(5) superconducting magnetic separation machine high gradient
Equipment structure: cycle of superconducting magnetic separation of the high gradient machine is a set of superconducting magnetic filters. Main part is superconducting coil, refrigeration institutions, sorting institutions, gives the ore institutions, etc. The superconducting magnetic machines can be used as:
1) magnetic separation process of basic research laboratory equipment;

2) simulation device operating conditions of large among the test with;
3) small in production.
