Chat OnlineApr 09 2015 · Tumbling mills. Tumbling autogenous (AG) mills are drum mills which consist of horizontally rotating slightly inclined cylinders of large diameter and small length and fitted with lifting bars. Coarse feed is entering the mill from one end and outlet is at the other end.
Chat OnlineGrinding in tumbling mills may be inefficient particularly where energy is wasted by impact that does not break particles. Autogenous (AG) and semi-autogenous (SAG) mills often operate in an unstable state because of the difficulty in balancing the rate of replacement of large particles from the seed with the consumption of the charge.
Chat OnlineThe IsaMill is a stirred-medium grinding mill in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput mills (such as ball mills and rod mills). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.

Chat OnlinePin mills are used to reduce the size of medium- to low-density materials such as talc and clay. Pin mills use centrifugal forces to smash large particles against pins. Equipment Design A colloid mill rotor is an intermeshing rotor used for the size reduction of materials by multiple impacts with the maze of pins.
Chat OnlineTumbling mills and some theoretical and practical aspects of milling are discussed. Attention is directed towards the difficulty of relating the dynamical analyses of the motions of particles within mills to the existing treatments of breakage processes. This synthesis may be advanced by a study of milling that utilizes the matrix analysis of breakage processes.
