A Study on Simple Grindings Methods of Sulphate Raw Materials

One of the important working procedures in premixed feed additives production is the grinding of sulphate raw materials. Dehydration through stoving will result in high cost and the feed products can hardly find a good market in China at the present time. As a result of our study, two simple processing methods are suggested in this paper,i. e. grinding of sulphate raw materials without stove-drying, which makes the grinding process more simple and much cheaper.
