Forged Low Carbon Steel – both 4 and 5 are the cheapest metal balls obtainable. They are only recommended for rough grinding, where metallic contamination is not objectionable.
Other, more special types include bronze or brass, aluminum, tungsten carbide, etc.
Special note:No matter how good the metal ball might be, care must be exercised in the operation of the Mill if excessive wear with its resultant contamination is to be avoided. (See other sections in this chapter; also sections on Cleaning and Discharging.) The following general rules should be carefully adhered to regardless of the type media used.
There should be enough material in the batch to cover the grinding media.
Grinding time must be watched carefully to avoid excessive grinding.
Excessive buildup of heat should be avoided. In paint grinding, this may lower the operating viscosity beyond the critical point. A reduction in Mill speed may help to avoid overheating, but it is more desirable to circulate a cooling medium around the cylinder. If the Mill is not jacketed, a water spray can be used with satisfaction.
The smallest grinding media should be employed. These not only reduce the danger of overheating but, as is well known, the smaller grinding media provide faster and better results.
When using extenders, their abrasive nature may cause excessive wear. To avoid this, some operators are able to hold out the extenders until the grinding is almost completed and then add them for the final operation. Get ball mill,ball mill,rotary kiln From http://www.ballmill8.com

Carl Madden - Search Engine Marketing Consultant at Osato Tree - There are many times I have been stuck on something, but now I that I am working with Teo Graca, I know I can get unstuck quickly. He has a way of getting at the meat of the solution to any problem when it comes to business planning. I really don't know anyone with such a well rounded skill set. I think that is what makes it possible for him to do what he does. I highly recommend Teo and Net-Teams! - March 15, 2012, Carl was Teo's client |
