Outotec vertical stirred mills do ... International MiningThe grinding chamber is filled up to 70% with grinding beads. Rotating discs stir the charge and grinding takes place between beads by attrition. The number of discs (grinding stages) depend on the application and can be up to 30. Feed slurry is pumped into the mill via bottom connection.
A Comparative Study on a Vertical Stirred Mill Agitator ...A series of stirred mill experiments were performed with two types of agitator designs a standard pin type and CSIRO's designed double helical screw stirrers. The effects of operating parameters such as grinding time, stirrer speed, and pulp density on grinding performance was investigated using a magnetite concentrate.
Investigating grinding media dynamics inside a vertical ...Although stirred mills are normally described as high efficiency mills, a significant part of the input energy is not utilised for the grinding process, but rather dissipated by heat and sound due to collisions and friction among beads and the chamber wall.
CL Attritors Limestone Grinding Mill | Union Process®, Inc.Stirred Vertical Ball Mill Limestone Grinding System. The economical CL Attritor Stirred Vertical Ball Mill is used for wet grinding limestone for flue gas desulphurization. The process uses limestone feed stock of approximately 6mm in size and wet grinds the limestone to 95% minus 325 mesh. The CL Attritor operates in continuous processing mode.

METHODOLOGY TO PREDICT PRODUCT SIZE DISTRIBUTION .mills for grinding in fine size ranges is inefficient and, therefore, vertical stirred mills are becoming increasingly popular in the mineral processing industry. This work presents hypotheses of a new methodology to predict the product size distribution of a vertical stirred grinding mill using the population balance model. Initially,
mill Technology Stirred The IsaMill is a stirredmedium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older highthroughput 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.
parts of stirred mill High Energy Ball Milling How It Works . Spare Parts Request Form; High Energy Ball Milling. In discussions on high energy ball milling, the more generic term ball mills is often used in place of the terms stirred ball mills or Attritors, but the differences between the types of mills are quite distinct.
Optimization of some parameters of stirred mill for ultra ...Mar 10, 2011· In this study, optimization of some parameters of stirred mill on ultrafine grinding of refractory Au/Ag ores was performed. A threelevel Box–Behnken design combining a response surface methodology (RSM) with quadratic programming (QP) was employed for modelling and optimization of some operating parameters in ultrafine grinding.
