20000 gauss high gradient dry powder magnetic drum separator

          20000 gauss high gradient dry powder magnetic drum separator

Introduction of high gradient dry powder magnetic separator

with the combination effect of strong background magnetic field, and the high ration magnetic force of second magnetic field, generated by the magnetic matrixes.

the ability to capture the weak magnetic Fe2O3 low impurity content in nonmetallic fine-grained minerals will be greatly enhanced to achieve the purpose of separating material.

The magnetic system is designed as horizontal pole-opposite semi-closure magnetic structure, and the separating chamber(working area) can be adjusted. when the working clearance is changed to 8mm, the intensity of the background magnetic field is over 0.95T.

the magnetic induction intensity at the end angle of the separation medium bar on the two system can reach 1.9T-2T. The magnetic field gradient can reach 1.6T/cm, which is widely applicable to the varieties in magnetic properties of different minerals.

the separating selection and grouping of equipment is carried out on separating medium rods. the production of high magnetic gradient and the capture of Fe2O3  impurities and determined by a series of factors, such as the material of medium rod, shape, relative size, arrangement mode, spacing and packing rate of the magnetic separator.

 Aplications  of  high gradient dry powder magnetic separator

Equipment Structure of  high gradient dry powder magnetic separator

The equipment consist of two magnetic system and its internal magnetic system, installed horizontally on the machine frame, which are driven to rotate oppositely by motor mechanism.

The whole equipment is protected by steel housing, on the top of which is equipped with Micro-Tremor(the vibrator is used to produce vibration to lose the minerals, thus reducing the resistance when the particles are inducted to drum surface.), negative pressure dust collector, and reception trough that is connected with auto weighing quantitative feeder. the undersides of equipment is discharge mouth of concentrate minerals , passage dam-board, and cleaning system.

Working principle of high gradient dry powder  magnetic separator

 From the discharging port of silo undersides, the mineral material firstly is conveyed by automatic weighing quantitative feeder, and fed into  reception trough quantitatively in a continuous way.  under the effect of micro tremor(vibrator), the minerals ,in loose, uniform and suspension state, fall into the working chamber.(between integrated magnetic system, the chamber cavity can be adjusted.),and is swept tangentially in motion by magnetic flux(magnetic comb) ,the impurities (Fe2O3,Ferric Oxide) is separated, selectively caught and absorbed onto the drum surface, by separation medium rod. along with the rotation , the Ferric Oxide is carried away from working area.

at the non-magnetic area, separation medium rod lose its magnetic force instantly.  by the work of cleaning device, the impurity fall into hopper, thus achieving continuous iron separating and removal.

Model Selection of  high gradient dry powder magnetic separator

Due to varieties of minerals in different world, we can customize the equipment according to the following factors:

the content of Fe2O3 in minerals, natural existing state ,particles size distribution, specific magnetization coefficient( specific susceptibility ), monomer liberation degree, selected grain-size of ore, iron removal requirements, processing capacity per machine, and technical specification sheet.

For the previous wet grinding production line, no matter how many iron-removal steps the plant have, what you do is, air-dry and heat dry the mineral, process with our equipment.

Successful Project Case of  high gradient dry powder magnetic separator

(1), high purity sand quartz, Feeding granularity: 0.21-0.10mm,the Fe2O3 content is reduced from 0.05% to 0.005%. (Project location: Hebei province, Xintai City)

(2), processing mineral: kyanite (cyanite). the Fe2O3 content is reduced from 2.79% to 0.6%.( project location:Henan province, Nanyang city)

(3), Processing mineral: feldspar. Feeding granularity: 0.18-0.10mm, the Fe2O3 content is reduced from 0.56% to 0.12%. (Project location: Hebei province, Handan city.)

(4), Processing mineral: andalusite. Feeding granularity: 1.6-0.5mm, the Fe2O3 content is reduced from 2.79 % to 0.55 %. (Project location: Xinjiang province, )

The above project demonstrate:

the weak magnetic impurities with specific susceptibility of 1.9x ---7.5x m³/kg in non-metallic minerals can be separated efficiently.
