TECHNICAL How to Spec a Mill Gear

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. Ball mills are smaller still and use a larger percentage of balls to perform most of the work. Large-di-ameter mills allow for use of gear ratios

The ignition time (t ig) of the mechanically induced self-sustaining reaction (MSR) process involving the formation of TiB 2 from Ti/2B elemental mixtures was used to study the influence of the ratio (k = -ω v /ω d) between the rotational speed of the supporting disc (ω d) and vials (ω v) on the milling efficiency of a Pulverisette 4 planetary mill.The variation of the inverse of the ...

Reduction Ratio

Friction reduction ratio is the function of the average velocity of fracturing fluid, the gelled agent concentration, and the proppant concentration. Based on the linear regression of 1049 experimental and field data, Lord et al. put forward the following empirical formula to calculate the friction reduction ratio of HPG fracturing fluid (Lord, 1987):
