Fine milling of ammonium sulphate

I need to reduce 20 ton / day of ammonium sulphate granulate, 0.5 to 3 mm size, to a fine powder passing 98% through 200 mesh .

What type of mill would give the lowest cost/ton ratio in terms of energy and labor input .

A classifing mill is desirable to avoid subsequent processing.

As you have already hinted at generally an Air Classifier mill is the most energy efficient technique. It also gives you a simple, one system, one pass process to produce a consistent particle size distribution.

There are several companies who can supply such milling systems. if you need any advise on who to approach please contact me by email.

Dear Sir

Our G&A AIRMILL is suitable to grind ammoniumsulphate in a single step to a fineness of 98% less than 200 micron or even finer.

A classifier is not necessary.

With the AIRMILL technology a classifier is not required

- lower investment costs

- less wear (no recirculation)
