A ball mill is a type of grinding mill, purposed similarly to the sag mill or other mining crushers. These machines are used to grind or mix metals or raw materials. Ball Mill. For grinding raw material and coal the air-swept ball mills are one proven grinding system. These mills are used to grind moist material that need to be. A Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground.

Ball mills

The Ball-Rod Mill Heads are oversize in section, heavily ribbed and are cast from electric furnace steel which has a strength of approximately four times that of cast iron. The head and trunnion bearings are designed to support a mill with length double its diameter.

This extra strength, besides eliminating the possibility of head breakage or other structural failure either while in transit or while in serviceimparts to Ball-Rod Mills a flexibility heretofore lacking in grinding mills.

The ball mill grinding cover is ball mill grinding from wear by heavy liners.

An extended lip is provided for loosening the door with a crow-bar, and lifting handles are also provided. The manhole door is furnished with suitable gaskets to prevent leakage.

After ball mill grinding, the trunnions are given a polished surface to minimize friction. Ball mill grinding mill trunnions are carried on heavy babbitt bearings which provide ample surface to insure low bearing pressure.


If at any time the normal length is doubled to obtain increased capacity, these large trunnion bearings will easily support the additional load. Trunnion bearings are of the rigid type, as the perfect alignment of the trunnion surface on Ball-Rod Mills ball mill grinding any need for the more expensive self-aligning type of bearing.

The highest grade nickel babbitt obtainable is used in the trunnion bearings and pinion shaft bearings. The cap on the upper half ball mill grinding the trunnion bearing is provided with a shroud which extends over the drip flange ball mill grinding the trunnion and effectively prevents the entrance of dirt or grit.

The bearing has a large space for wool waste and lubricant and this is easily accessible through a large opening which is covered to prevent dirt from getting into the bearing. Ball and socket bearings can be furnished. Welded steel scoop feeders ball mill grinding, however, be supplied in any radius.

The correct size of ball mill grinding depends upon the size of the classifier, and the smallest feeder should be used which will permit gravity flow for closed circuit grinding between classifier and the ball or rod mill.

All feeders are built with a removable wearing lip which can be easily replaced and are designed to give minimum scoop wear. A combination drum and scoop feeder can be supplied if necessary.

This feeder is made of heavy steel plate and strongly ball mill grinding. These drum-scoop feeders are available in the same sizes as the cast iron feeders but can be built in any radius.

Scoop liners can be furnished. The trunnions on Ball-Rod Mills are flanged and carefully machined so ball mill grinding scoops are held in place by large machine bolts and not cap screws or stud bolts.

Ball Mills

If the peripheral speed of the mill is too great, it begins to ball mill grinding like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill.

To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with ball mill grinding material continuously being recirculated back into the mill to be reduced.

Classifying and pulp-handling machines that will handle a circulating load of at least per cent, of the original feed should be provided.
