8.3.4. Reduction Ratio in Rod Mills. The reduction ratio, R, in rod mills varies from 2 and 20 depending on the characteristics of the ore. The usual reduction ratio is about 8. According to Bond , the reduction ratio is a function of length and diameter of the mill. The optimum reduction ratio, R RO, can be written as (8.2) R RO = 8 + 5 L D .

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 -50% of the mill volume and its size depends on the feed and mill size.

of an industrial tubular ball mill, some researches were done such as monitoring level of coal powder filling in an industrial ball mill as a function of mill`s power draw or investigation on the ball filling ratio under batch wet conditions, due to load density alters [2, 3]. In addition it is to be.
The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
The roller crusher is employed for coarse crushing, or when massive size reduction ratio is important. The roller surface typically seems teeth or groove to boost cleaving force. Traditionally, plants used ball mill to grind clinker and gypsum into cement.
To investigate the relation between reduction ratio and mechanical properties of killed mild steel plates, the following tests were carried out. (1) Six 10-t ingots from a coarse austenitic-grained heat melted with a basic open hearth furnace were hot-rolled into several plates of different .

Have an open when searching for this. It is definitely the most expensive and most important part in your ball mill, but if you look around enough you can surely find one for free. The motor should probably run at a least 500 rpm. Higher is fine; it'll just mean you'll need a greater reduction ratio.
