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

 Eura Unrath - Scientific Photographer at Roboto Industries - Teo wrote my business plan and found some revenue models I hadn't considered. I am looking forward to working with Teo on some of the things in the plan. Great work. Great at finding potential problems and working through to the best answer. I had a good time working with him too. If you need a business plan, Teo does a great job! - March 17, 2012, Eura was Teo's client |
