A method to identify wet ball mill's load based on
In this paper, a novel method of wet ball mill load identification based on CEEMDAN, RCMDE and SRNN is proposed. Firstly, CEEMDAN-RCMDE is used to extract the load features of the ball mill. Then, taking the advantage of SRNN's fast training speed and strong generalization ability, a mill load identification model based on SRNN is …

Autogenous Mill | SpringerLink
The autogenous mill will grind the material to the extent that the content of the particles with particle size <0.074 mm accounts for 20–50% of total quantity of product, and crushing ratio is 4000–5000, which is over 10 times that of ball mill and rod mill. The maximum particle size of the lump ore fed into autogenous mill is 300–350 mm.

Ball Milling
Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134–141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
