Crushing limestone to 30 mesh?

Question

I am mining limestone lums of size 200 mm to 300 mm. I want to reduce the size below 30 mesh powder. What kind of grinding media will help me to go further to 30 mesh powder with lower cost. I want 10tones/hr capacity plant. Please give me suitable suggestion.

Answer 1

VSI impact crusher will do job nicely. http://www.crusher-china.com/crushing-ma...

Limestone is a beautiful material to be produced by a VSI (vertical shaft impact crusher).

COST per ton is not highly abrasive, will be around 0.2 cents per ton. Limestone impacts and breaks easily, can do up to 600-800 STPH depending on the crusher model picked.

I have sold about 15 of these type of crushers in limestone and sand and gravel and well proven technology.

You are going to yield a nice CUBICAL, ANGULAR product. Pluses low mtce crusher, easily to use, maintain, operate and change impellers vs other types of devices. http://www.crusher-in-china.com
