The Modelling Of Autogenous Grinding Sciencedirect

Sep 01, 1989018332This groups the attri- tion and impact modes of Digre. In ball milling the amount of grind- ing work done by attrition and impact is close to 100. In autogenous grinding Digre estimates that attri- tion and impact are only 20-50 of total and abrasion is the main mode of grinding. Coarse lumps are quotproducingquot fines by different mechanisms.

Improving Autogenoussemiautogenous Grinding

The comminution process indicates that the most energy-efficient comminution system would be one where the particles leave the breakage field as soon as they reach product size. Contrary to the free falling gravitational vertical flow in crushers, the grinding mills energy efficiency essentially depends on ore characteristics and the discharge rate of broken particles, which...

Case Boliden Autogenous Mill Application 131017

An autogenous mill is a mission critical application found in the concentrator section of a mine. The mills primary task is to grind ore into a suitable size for the next step in the concentration process. There are many different types of mills ball mills, rod mills, SAG Semi-Autogenous Grinding and autogenous mills.

Tion of slurry inside the mill. Each autogenous mill was subsequently run in open circuit in the fully autogenous mode and, as planned, each was followed by one ball mill in closed circuit with six 508 mm vertical hydrocy- clones. This configuration resulted in a finer flotation feed size an unintended result with respect to the original ...

Molecular Dynamics Of Comminution In Ball Mills

Dynamics to the simulation of autogenous dry comminu-tion in a tumbling ball mill 18. To this end we devised a novel algorithm which accounts for the fragmentation of particles. First we will demonstrate that experimen-tally known results, in particular those by Rothkegel and Rolf 1,2, can be reproduced up to a good degree of ac-curacy.

Technical How To Spec A Mill Gear Power Amp

Mill, it needs to have a bore larger than the mill outside diameter. The mill out-side diameter is a function of the grind-ing process selected. Autogenous mills are the largest in diameter since the feed grinds itself. A semi-autogenous mill uses some metallic or ceramic balls to assist the grinding process and can be slightly smaller.
