Stirred Mills – Ultrafine Grinding - ScienceDirect
01/01/2016· The horizontal IsaMills are generally used as a regrinding mill to liberate the finely dispersed mineral of economic interest. The feed is usually the cyclone overflow from conventional grinding circuits such as a ball mill circuit. The grinding media fed with the mineral slurry occupies 70–80% of the internal volume of the mill. The feed travels towards the discharge through the openings in the discs and also along the annular space between disc and millStirred mills - for wet grinding - Metso Outotec,Ideal for grinding finer products, stirred mills are known for their energy efficiency and compact design, reducing floor space requirements.

The stirred mill has an impeller that places the seals and bearings into the batch. The stirrer axis is fitted with five slotted stainless steel shafts andImpact of the stirred mill grinding mechanism on the,,1.1 Grinding mechanism of a vertical mill with vane rotors STM/Outotec’s HIGmill™ is a “stirred media” grinding mill where the stirred effect is caused by rotating vane grinding discs (rotors) together with stator rings situated on the shell. The shape of the mill offers a small footprint. The general structure and its main components are presented in the Figure 1.TECHNOLOGY SELECTION OF STIRRED MILLS FOR ENERGY,,Stirred mills are in general applied to fine and ultra-fine grinding applications. For the purposes of this paper, grinds of up to 75 µm are regarded as conventional, between 75 and 30 µm as regrind, below that and up to 10 µm as fine grinding, and finally below 10 µm as ultra-fine grinding.
Stirred Media Detritors (SMD) - Metso Outotec
Stirred Media Detritor (SMD) is a fluidized media grinding mill. It utilizes the rotational energy of the impeller arms to impart a high-energy motion to the media and slurry mixture inside the mill. This results in particle-to-particle shear and compressive forces that produce the desired grinding mechanism for fine grinding.
