Hi 

I am working in a quartz processing plant. 

We have a VSI and after the sieve the output is with 1-10mm -50% and <1mm -50 %.We can separate the iron particles from our permanent magnetic bars(15000 Gauss) for the range of 1-10mm. But we couldn't for the ones with <1mm.

  1.  Cant we get the output about 80% from 1-10mm and 20% from <1mm?
  2. or is there anyway to remove the iron from <1mm ?

Do you have the VSI in closed circuit with a screen?  If so, change the top screen aperture to a finer size to increase the circulating load around the VSI - this will reduce over reduction.  You can also open the ports on the VSI (if it has them) to coarsen the material.  Also you can increase the feed size to the VSI or slow it down.

Just my thoughts I dont have a lot of VSI experience!
