pulp filling ball mill

What are the differences between ball mill and rod mill ...

Overflow discharge ball mill is designed with no sieve plate so that the ore pulp can be discharged directly without filtration. It is very simple in structure and convenient in maintenance. Though there is no sieve plate, the discharge pipe is cast with reverse threads, which makes that the large ores and balls are hard to discharge from the ...

BPG Filling of Losses - Wiki

Ball mills and laboratory beaters can be used for producing small quantities of acceptable pulp. Another suggestion is to shake .5cm glass beads with torn squares of paper suspended in water in a corked flask to produce pulp. (Petherbridge 1980) Pulp storage: Stock pulps may be kept in water in tightly capped labeled jars in the refrigerator.

Grinding Balls & Rods

The minimum size of grinding balls should be selected with caution since there will be a tendency for such balls to float out of the mill in a dense pulp (this is minimised by the use of a grate discharge mill). Also the smaller the media the quicker it will reach its reject size.

HOW BALL MILL WORKS? - energosteel.com

Mills with unloading through the grid sometimes called mills with forced unloading or mills with a low level of pulp. This type of ball mill has a grid with openings for unloading crushed material and located in the unloading end of the drum. The grid has radial rib-lifters on side facing to the unloading end cover.

Ball Mill Explained - saVRee

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

Grinding Balls & Rods

Grinding Balls. Steel balls ranging from ¾ to 5 in. in diameter are used. Rods range from 1½ to 4 in. in diameter and should be 3 to 4 in. shorter than the inside mill length. Tube mills are usually fed balls smaller than 2 in., whereas 4- or 5-in. balls are more commonly used for ball-mill grinding.
