      磁選機?筒體轉數大小對工作有什么影響呢
      作者:管理員    發布于:2016-09-02 04:09:18   

      1)磁選機筒體轉數:

      1) separator cylinder speed:

      一般地說永磁磁選機直徑小的采用高轉數,例如Φ600毫米直徑采用40轉/分,直徑大的采用低轉數例如Φ750毫米直徑采用35轉/分。

      Generally speaking, high speed permanent magnetic separator with small diameter, such as Phi 600 mm diameter by 40 rpm, large diameter with low speed such as Phi 750 mm diameter by 35 rpm.

      磁選機轉速的大小主要對處理能力影響較大。轉數高處理能力大,轉數低處理能力低。轉數高的磁選機在運轉中,由于速度比較快,磁性小些的連生體和脈石上來的機會就少,只有那些磁性較高的礦粒才可能選別上來,因而精礦質量就高些。

      The size of the magnetic separator is mainly affected by the processing power. High speed large capacity, low processing capacity and low speed. High speed magnetic separator in operation, due to the faster, smaller magnetic coenobium and gangue up far less opportunity, only those particles may be higher magnetic separation, so concentrate on higher quality.

      反之轉數低,速度相對較慢,由于磁感應作用使磁性弱些的礦粒也有機會選別上來,造成精礦質量受到影響。因此必須根據礦石特點,指標要求,選擇合適的磁選機轉數。

      But the relatively slow speed, low speed, the magnetic induction effect to some weak magnetic mineral particles also have the opportunity to choose don't come up, which affected the concentrate quality. Therefore according to the ore characteristics, requirements, select the appropriate number of magnetic separator.

      2)磁系偏角:

      2) magnetic declination:

      由國家正式批準生產的磁選機,在靠傳動側的軸頭上都裝有磁偏角指示裝置,搬動調整螺母就可調節磁系偏角的大小。磁偏角的角度過大過小都不好,過小影響精礦質量,使磁性較小的顆粒有機會選別上來,但會使尾礦品位降低,對回收率有好處;角度過大,對提高精礦質量有好處,因為只有磁性大的顆粒才有機會被選上來,磁性小的就沒有機會上來而進入尾礦,使尾礦品位增高,降低回收率。

      By the state formally approved the production of magnetic separator, on the side of the drive shaft is provided with a magnetic declination indicating device, moving the adjusting nut can adjust the angle of magnetic system. The declination angle is too large or too small are not good, too small to affect the magnetic concentrate quality, smaller particles have a chance to choose don't come up, but will reduce the grade of tailings, is good for recovery; angle is too large, is good for improving the quality of concentrate, because only the magnetic particles have a chance of being elected. There is no chance of a small magnetic up into the tailings, the tailings grade increased, reduce the recovery rate.

      所以,磁偏角大小多少合適必須根據作業要求來調整,磁選機一般生產現場磁偏角均調整在15°—20°左右。調整好的磁系偏角,在生產中如果操作條件及要求沒有變化,不要輕易隨便動

      So, how much the right size declination according to the requirement of work must be adjusted, the general separator production site were adjusted in 15 degrees declination - 20 degrees. Adjust the magnetic declination, in production if the operating conditions and requirements did not change, don't move
