They tend to grind more efficiently than, for example, ball mills with feeds as coarse as 6 mm to products finer than 20 microns.

grinding media" was presented (Stehr, 1988). The year 1948 saw the successful application of Du Pont's "sand mill" for pigment grinding. Subsequent years have led to the development of different types of stirred mills spanning a number of industries that require fine and ultrafine grinding.

Vertimill, recent regrind applications in processing Iron ores where the impact of lower energy and grinding media consumption is very significant because of the large tonnages involved, and also applications as a tertiary and secondary grinding stages of grinding circuits.

In general, the finer the media size used, the more efficient the grind, but there is a limitation. A larger media size is required to grind the coarser material, so the media advantage of the Vertimill® is more prevalent for finer grinds. This is one of the reasons for a variation in Vertimill® efficiency range (30-50%) compared with ball mills.

The level of your grinding media in the Vertimill can only be checked when the Vertimill is properly Locked Out / Tagged Out! This is called the 'Static Ball Charge Measurement' in the Vertimill manual. Once the mill is stopped, a calibrated rope with a non-magnetic weight securely fastened at one end can be dropped in the ball charge chute ...

GRINDING MEDIA WEAR AND ENERGY TRANSFER Cost and performance are the primary considerations when selecting grinding media. Almost half of the operating costs of the SMD® mills at Century is the cost of grinding media (Burgess et al, 2001). Properties that affect the choice of grinding media include: - Size - Type - Competency - Hardness

The Vertimill™ is a vertical agitated media mill with a double-helical steel screw agitator located centrally in a vertical cylindrical shell.The screw agitator lifts the media and circulates it throughout the mill. The higher efficiency of the Vertimill™ is due to the higher frequency of lower energy impacts and, by the same token, smaller frequency of higher energy impacts when compared ...
