Again, if you have a better mill, you could use the ball ended endmill to hog away most of the material in a roughing pass and then change to the engraving cutter for the last little bits. I found that milling the coin in a spiral path from the center out produced best results, as compared to milling following the X and then Y axis, but you may

Below is the write-up of how a ball mill works, is used to crush ore and an explanation regarding its effectiveness in gold mining. The Purpose of Milling First of all, in order to get the best out of how this particular equipment is used it is important to get acquainted with knowledge on what it is, and is made of.
A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.
this is a high energy ball mill that opens up a whole world of possibilities. It takes a bit longer though.
gold processing - gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for
Mates & Gold show how to process paydirt and reef gold in a home-made ball mill. Hard Rock Mining Gold and Silver Ore and processing it There are a number of different haulage methods for transporting rock through a mine to the portal.
Here you can see an overview of the ball mill with the drum removed. Construction is super simple. Just three pieces of wood plank banged together to make a platform for mounting all the parts. The platform is made from a 1X10 wooden plank 14 inches long. It sits on two pieces of 1X4 wood.
Cement mixer turned into ball-mill to process gold ore. A neat idea and I wish I could have talked to the man who tried it. All I can do is talk to people who know he tried it. After some searching I located two o... Read more ».

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed
Small Ball Mill of 2t/h for Gold Ore. Gold is a kind of rare mineral resource in the nature after being extracted from common ores and comes with highly industrial value. With the development of technology, the sales volume of gold ore processing equipment has been gradually increased, so is in the demand of small ball mill in the market.

Posted December 29, 2012. I would suggest that you build a rod mill if you want to get the material down to a fine power, a ball mill usually is used to make bigger item smaller, e.g. big rocks down to little rocks, and then the material goes into a rod mills to take it down to a powder.
The milling of the materials is a very useful procedure in various domains in life as well as in the constructive domain. Click HERE to subscribe to Make it...

1 to 15 TPH Small Scale Miner’s Ball Mill. Our small-scale miner’s Ball Mills use horizontal rotating cylinders that contain the grinding media and the particles to be broken. The mass moves up the wall of the cylinder as it rotates and falls back into the “toe” of the mill when the force of gravity exceeds friction and centrifugal

Ball milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force. Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation.

Tube mills are usually fed balls smaller than 2 in., whereas 4- or 5-in. balls are more commonly used for ball-mill grinding. A much higher grinding capacity is obtained in tube mills by using steel media instead of pebbles, but in making such a conversion serious consideration must be given to the ability of the steel shell to withstand the
