1 EIA, an independent arm of the Department of Energy, is the primary public source of energy statistics and forecasts for the United States. The estimated amount of new generating capacity is taken from the Excel output spreadsheet for the Annual Energy Outlook 2008 report. Note that EIA forecasts assume no change to the laws and regulations
Grid ball mill is widely used in smashing all kinds of ores and other materials, ore dressing and national economic departments like building and chemical industries etc. The size of ore shall not exceed 65mm and the best feed size is under 6mm. The effect in this job is better than coarse grinding.
The milling is a process of metal-removing by feeding the workpiece passes through the rotating multipoint cutter. The diagram of the cutting operation is shown below: Milling machine cutter and workpiece position. This machine can hold one or more cutters at a time and rotates at high speed to remove the metal at a faster rate.
