试验室FG型单螺旋分级机技术参数
Technical Parameter of Laboratory Single spiral classifier

螺旋分级机适用于矿石、非金属物料进行脱水、脱介、脱泥和干湿式分级。

This classfiers suitable for dewatering,medium,drainaging amd spraying in ore clressing for medium and fine naterial wet and dry classifying in mine.

螺旋分级机是借助于固体粒大小不同，比重不同，因而在液体中的沉降速度不同的原理，细矿粒浮游在水中成溢流出，粗矿粒沉于槽底，由螺旋推向上部排出，来进行机械分级的一种分级设备，能把磨机内磨出的料粉级于过滤，然后把粗料利用螺旋片旋入磨机进料口，把过滤出的细料从溢流管排出。该机底座采用槽钢，机体采用钢板焊接而成。螺旋轴的入水头、轴头、采用生铁套，耐磨耐用，提升装置分电动和手动两种。

Spiral classifier is a type of classifying equipment which realizes mechanical classification under the principle that materials settle in the liquid at different speeds due to different grain sizes and weighs: Fine grains float in the water and move out in case of overflow while coarse grains sinks to the bottom of tank which are then pushed upward by spiral. It can filter material powder grinded in the mill, and then get the coarse materials into the feed inlet of mill through the spiral slices as well as discharge the filtered fine materials out of the overflow pipe. The base of such machine is made of channel steel. Its body is welded with steel plate. Cast steel covers are used for the water inlet and spindle nose of spiral shaft which is wear-resisting and durable. The machine’s lifting device can be used manually or electronically.
