[QUOTE=MaZaGAngeE;57620]for limestone what is the best crusher with minimum power , maintenance cost ?

Feed size : 50*50 cm

output size : range 1- 600 micron

2- 300 micron

3- 200 micron

4- 100 micron

production rate : 50 tons per hour .

also i'll use its output as a feed for ball mill to reduce particle size down to 5 micron .

[B]

i was thinking for this line :

jaw ( 50*50 to 100 mm ) then using a belt conveyor an impact crusher ( reduce product down to our range ) then a separator .

The question your asking us to answer directly at no cost to you is one with too many variables, and you should be asking a crushing equipment seller/system designer such as Crusher Dynamics Inc. as it entails a properly designed turn key system.
