Product overview
   Electromagnetic high frequency vibrating screen is applied in classification work of mill grinding classification process.In appropriate feed concentration, feed particle (200 mesh fraction content) and the demand of granularity and the difference between the feed particle size is less than 30% under the condition of sieving rate is as high as 70% above.Can greatly reduce the cycle load and oversize qualified grain content in the content, improve the processing capacity of mill.(usually 5-10%) less on the screen.Improve grinding efficiency to reduce the amount of grinding, improve the grade of iron essence pink and yield.
    由于篩分效率高，可大幅度降低循環(huán)負(fù)荷和篩上物中合格粒級(jí)含量，從而提高磨機(jī)的處理能力（一般可提高5-10個(gè)百分點(diǎn)）；篩分過(guò)程對(duì)篩下物粒度控制嚴(yán)格，可消除過(guò)粗礦粒對(duì)精礦質(zhì)量的不利影響礦漿在篩面高頻小振幅振蕩作用下，有按密度分層的作用，高密度小顆粒易于沉降至料層底部而透篩，因此可明顯提高篩下物料的質(zhì)量。目前在大型礦山選礦廠及中小型選礦廠得到廣泛應(yīng)用。成為冶金礦山選礦行業(yè)細(xì)篩分級(jí)工藝廣泛采用的設(shè)備。
    Due to the high screening efficiency, can greatly reduce the cycle load and oversize of qualified grade levels, so as to improve the processing capacity of mill (general 5-10%) can be improved;Strict screening process for undersize material granularity control, can eliminate too coarse particles of the negative impact of the concentrate quality pulp in high frequency under the action of small amplitude oscillations of screen surface, has the effect of density stratified sampling, the high density small particles are easy to fall into the bottom layer and through sieve, thus can obviously improve the quality of the undersize material.At present in large mine concentrator and small and medium-sized concentrator is widely used.Be widely used in metallurgy mineral fine screen classification process for mining industry equipment.

電磁高頻振動(dòng)篩性能及特點(diǎn)

Features
1、 篩面高頻振動(dòng)，篩箱不動(dòng)。整機(jī)經(jīng)二次減震支撐，動(dòng)載荷極小，可隨意擺放安裝。
1, high frequency vibrating  surface, screen box is immobility.The whole machine by the secondary suspension, dynamic load, can be installed in random.
2、 篩面震動(dòng)頻率50HZ,振幅1-2毫米。震動(dòng)強(qiáng)度達(dá)8-10倍重力加速度，是普通振動(dòng)篩強(qiáng)度的2-3倍。篩面自清理能力強(qiáng)，篩分效率高處理能力大。
2, Screen surface vibration frequency is 50 hz, the amplitude of 1-2 mm.Vibration intensity of 8 to 10 times the gravitational acceleration is common vibrating screen strength 2-3 times.Screen surface self-cleaning ability, ability to process high screening efficiency.
3、 篩面有三層不同的篩網(wǎng)組成。底層為鋼絲繩芯聚氨酯拖網(wǎng)，與振動(dòng)裝置接觸。拖網(wǎng)上面為兩層不銹鋼絲編織網(wǎng)粘接在一起的復(fù)合網(wǎng)，復(fù)合網(wǎng)上層與物料接觸，上層網(wǎng)可根據(jù)篩分工藝要求確定網(wǎng)孔尺寸。篩網(wǎng)開(kāi)孔率高，使用壽命長(zhǎng)。篩網(wǎng)兩段有張緊掛鉤便于安裝。入料緩沖篩板減小物料對(duì)篩網(wǎng)的沖擊，延長(zhǎng)使用壽命。
3, There are three layers of different mesh screen surface.The underlying polyurethane trawling for wire rope core, contact with vibration device.Trawling for above two layers of stainless steel wire woven mesh bonding together of complex network, composite layer in contact with the material online, the upper mesh is according to the requirement of screening technology of mesh siz is hie.Screen mesh opening rate is high, long service life.There is a tight link to facilitate installation screen two paragraphs.Into the buffer material sieve plate reduce the material impact on screen, prolong service life.
4、 高頻振動(dòng)篩安裝角度可隨時(shí)調(diào)節(jié)，已使用不同物料性質(zhì)及不同篩分作業(yè)。機(jī)械的安裝角度25-30度范圍。
5、 篩機(jī)震動(dòng)參數(shù)采用單片機(jī)調(diào)節(jié)控制。對(duì)每個(gè)震動(dòng)系數(shù)的震動(dòng)參數(shù)可單獨(dú)調(diào)節(jié)設(shè)定。除一般工況震動(dòng)參數(shù)外，可設(shè)定簡(jiǎn)短瞬時(shí)強(qiáng)震參數(shù)以隨時(shí)清理篩網(wǎng)，保持篩網(wǎng)不堵。
6、 電磁鐵震動(dòng)系統(tǒng)采用優(yōu)質(zhì)的橡膠件連接，長(zhǎng)期運(yùn)轉(zhuǎn)功耗小。

4, high frequency vibrating screen installation angle can be adjusted at any time, have been used different material properties and different screening operation.Mechanical installation Angle range of 25 to 30 degrees.
5, Screen machine vibration parameters adopts single chip microcomputer control adjustment.For each motion parameter can be set in a separate adjustment coefficient of vibration.In addition to the general condition of motion parameter, instantaneous earthquake parameters can be set a brief to clear the screen at any time, keep the screen wall.
6, Electromagnet vibration system is made of high quality rubber parts connection, long running low consumption.
