ABSTRACT:
The invention relates to a method for the comminuting of natural or synthetic mineral products having a size of 10 nm to 30 mm, which are obtained from the upstream process in pre-comminuted form for example in a roller mill for inter-particle comminution, wherein these solids are further comminuted in a working process initially dry then wetted with liquid and in this liquid are comminuted so as to obtain a suspension that can be pumped, which suspension is subsequently ground to the desired final fineness by means of agitating mills.
