Model Selection Guide
Choosing magnetic separator correctly should consider the iron content,the iron removal requirement,working environment and the technical data of the magnetic separator itself.
When the iron content is very much in the material,should choose the continuous Self-cleaning Electromagnetic Separator,Permanent magnetic separator.(RCDC, RCDD, RCDF, RCYC, RCT, CFLT series).
3.When the iron content is not too much in the material,should choose the Manual Cleaning Electromagnetic separator  or Permanent magnetic separator. (RCDA RCDB RCDE and RCY series) Reducing the suspension height appropriately can remove the iron better.
 4. Working in the serious dust environment,should choose complete sealed structure magnetic separator,such as RCDB,RCDZ, RCDE,RCDD, RCDF series Electromagnetic separator or RCYB,RCYD series permanent magnetic separator.
5.when the electricity power capacity is limited,appropriate to choose permanent magnetic separator.
 6.When the magnetic separator installed in the front of the conveyor, the material with impact force and in the condition of loose, the material of the driving wheel (which is in bottom of the magnetic separator ) should be non ferromagnetic materials
7. When the magnetic separator installed in the middle of the conveyor,to improve the effect of iron removal,can add a WCG series non ferromagnetic straight roller under the belt.
8.If material contains non ferromagnetic metal material which can't be attracted by the magnetic separator,should install the GJT(JYG) series metal detector to test,alarm,pick the metal out manually after stop the machine.
9.Magnetic separator has below feature:
 Remove the big and long iron easier than small and short piece, romove the sharp shape iron easier than the round piece,Remove the iron in the condition of moving easier than rest.In the  environment with  high standard of iron removal,should choose high performance magnetic separator or adopt multilevel magnetic separator.
When choosing the  multilevel magnetic separator,the magnetic separator in the back should be higher in iron removal performance than the magnetic separator in the front.Or, the magnetic separator in the back will be lower efficiency in iron removal.
When the iron content is just a little in the material,adopting GJT(JYG)series metal detectors to use accompany with the strong excitation electromagnetic separator,can save electricity powder and work well in iron removal.
12.There are many methods of iron removal to magnetic materials,if the situation is complicated,please contact with our technical department,we can design the magnetic separator specially  according to your special work environment. 
Note: The machine dimension and Data in this Catalog just for your reference of choosing the model.
