  • Brief introductions for Gravity Jigger Separator

    Now Gravity Jigger Separator has formed series whose application is expanded.  Such type of jig uses electromagnetic stepless speed regulation which features even rotation, smooth ore current, strong adaptability to selected materials,  good separation effects of medium and fine grains,   and water saving. Since such jigs have large  handling capacity and wide range of sorting particle sizes as well as are easy  for operation and maintenance, they are mainly used to sort alluvial gold,  tungsten ores, tin ores, hematite, and beach placer.

    Traditional  jigs mostly adopt circumferential off-center drive. Their jigging pulsation  curves are mostly sine waves. The ascending and descending water flow velocity  and action time produced by septal movement are basically the same. These  hinder the loosening of jig beds and layering of ore grain according to gravity.  Therefore, the sorting ratio and recovery rate of equipment are affected.

     

     

    Equipment Features of Gravity Jigger Separator

    Saw tooth wave jigs are a kind of energy-saving gravity equipment development and  improved on the basis of traditional jigs according to the theoretic layering  law of jig beds. Their jigging pulsation curves take the shape of sawtooth  waveform which gets the ascending water to travel more rapidly than the  descending water. The ascending time is short while the descending time is  long. The problem that the ascending and descending water flow and action time  produced by sine wave and pulsation wave are the same is solved. The looseness  of the bed is strengthened and suction function is alleviated so that the heavy  ore grains in the minerals are able to precipitate fully and the sorting ratio  ability and recovery rate of equipment are largely improved. Compared with sine  wave jigs through industrial tests, the recovery rate of sawtooth wave jigs are  higher than that of sine wave jigs respectively in Sn:3.01%, W:5.5%, Pb:1.63%,  and Zn:2.04%. The water consumption is reduced by 30%to 40%. The area of  flooring area is reduced by one-third and the stroke can be adjusted. Since  electromagnetism governing-speed motors are adopted for dragging to enable the  jig frequency to be steplessly regulated and their parameters reached advanced  domestic level, such jigs are one of the ideal types of energy saving gravity  separation equipment.

     

    Equipment Installation of Gravity Jigger Separator

    For gravity jigger separator, the  bottom surface of the frame must be installed horizontally to ensure the  gradient of the screen in the tank is within the design scope.
