pulp filling ball mill

conditions in the ball mill. The secondary mill at Waterval UG2 Concentrator was already fitted with an online ball and pulp load sensor, the Sensomag. The information obtained from the sensor is in the form of shoulder and toe positions for the ball and pulp filling in the rotating ball mill. The mill was surveyed at various

indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between mill absorbed power and ball filling degree. As indicated on

The secondary mill at Waterval UG2 Concentrator was already fitted with an online ball and pulp load sensor, the Sensomag. The information obtained from the sensor is in the form of shoulder and toe positions for the ball and pulp filling in the rotating ball mill. The mill was surveyed at …

The ball load and pulp load have a significant influence on the ball mill product size and production capacity. To improve the circuit performance at industrial scale these variables must be tweaked to levels where the plant can get grind and capacity benefits.

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.

The mill is equipped with a Sensomag which provides information about the ball load and pulp volume, values and positions. For each density tested, mill …

Pulp Filling Ball Mill. grinding mill in which ball charge mill filling and mill speed are varied to attain maximum throughput liner design for the sag was also approached more from a wear perspective rather than a metallurgical and hydraulic-flow perspective the.

Optimization of mill performance by using online ball and pulp measurements Stresses, generated in the ball charge, increase, which may result in spalling of balls and blocking the grate

Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

To have a pulp as dilute as 20 percent solids, the ball load was drawn down to 30 percent volume and the ore charge proportionately reduced. Water was then added to fill the mill. The results of grinding were much like those with 33 percent solids. All in all, 33 percent solids was the best for efficiency and selective grinding.

A total of 15 surveys were performed around the Waterval UG2 Concentrator secondary ball mill, at three different ball filling degrees and four in-mill density levels as part of optimisation studies. The filling degree and pulp level were measured using an on-line sensor called "Sensomag", developed by Magotteaux.

The mill filling should be measured at a minimum of 3 points along the mill. Excess of slurry could also be estimated. To get rid of pulp and rocks …

The last test—the one with 20 percent solids—had to be specially arranged because, as stated, a charge with 33 percent solids filled the mill. To have a pulp as dilute as 20 percent solids, the ball load was drawn down to 30 percent volume and the ore charge proportionately reduced. Water was then added to fill the mill.

Research highlights Industrial scale test work on an overflow discharge ball mill. Ball filling and % solids were varied, and mill performance compared. On-line pulp and ball angles measured with Sensomag unit. Mill performance linked to quantity and quality of ball/pulp interactions.

Ball Milling A Green Technology For The Preparation And. Lu et al employed the ball mill to obtain nanocrystals from bamboo pulp by a mechanochemical treatment in the presence of phosphoric acid 38 the pulp was firstly pretreated using a fibre dissociation device the obtained material was then ball milled for 1535 hours at 400 rpm in the presence of phosphoric acid to …

Furthermore, for a mill running at 70 % of the critical speed the ratio of the power when grinding a pulp of 50 % density to the power when dry grinding is about 0.6 to 1.0: which is in accord with the previous general statement that when wet grinding the power demand is about 60 % of that when dry grinding.

mill with a 30 mm graded ball charge and a 30% filling degree. The mill discharge pulp density was increased from 68.8% to 75.9% solids. The data is summarized in Table III. The example in Table III illustrates that the density has a large influence on the grinding efficiency. In this case, the optimum %<75 µis in the region of 73.4% or 1.989 kg/l
