A process for forming balls from mineral ores, particularly iron ore, in which water is added to the ore and the balls are produced in a balling drum. The surface wetness of the balls so produced is determined by apparatus which measures the intensity of light reflected from the balls in a selected direction, and the output from the measuring apparatus is used to …

The balling drum equipment fundamentally consists of an inclined rotating cylindrical shell with water sprays in its inlet end, where the feed material is introduced to make balls. All formed …

Balling drums, for instance, are designed to agglomerate iron ore into rolled balls (pellets). Additionally, heap leaching drums extract usable metal from ore. Common names for an agglomeration drum include: …

Mark off four spots — two each on the horizontal and vertical axes. Measure from 1 to 3, the vertical axis, and then 2 to 4, the horizontal axis, as shown in the figure. Next, rotate the drum 90° and measure from 1 to 3, which is now on the horizontal axis, and 2 to 4, which is now on the vertical axis.

Rotary Dryer Design & Working Principle. For evaporating moisture from concentrates or other products from plant operations, Rotary Dryers are designed and constructed for high efficiency and economy in fuel consumption. Whenever possible to apply heat direct to the material to be dried, Rotary Dryers of the Direct Heating Design …

To determine whether your drum is flexing, begin by taking internal measurements while the dryer is down. Mark off four spots — two each on the horizontal and vertical axes. Measure from 1 to 3, the …

Brief description of continuous balling circuit and MLP has been described in this section. 2.1 A general balling circuit. Continuous balling process takes place in a closed feedback circuit, consists of rotatory device such as drum or disc and screen to classify green balls according to their size (Fig. 1).Typical circuits may contain other …

We have performed a theoretical analysis on the balling drum circuit and have found that the balling process is essentially a non-linear feedback system, with non-linear …

The balling drum circuit as conventionally used in iron ore pelletizing plants is analyzed from a control engineering viewpoint and a simple model presented. An …

Incorrect process parameters cause macroscopic density gradient [3, 12, 31, 74, 75] due to unmelted powder (Fig. 8.7A–F) and the balling effect. unmelted powders cause localized unconsolidated regions (Fig. 8.7A) and unmelted pockets (Fig. 8.7C–F [12]; [76]).The numbers and the wideness of the unmelted regions could be reduced by increasing the …

The mixing is done usually in vertical or horizontal high intensity mixers to achieve a homogenous blend of ore and additives. From mixing the filter cake is sent to the balling area where the ore is agglomerated on balling discs or balling drums into green (or unfired) pellets. Both drums and discs ball the ore to about 9-16mm size.

Balling drums consist of a large, cylindrical "drum," through which the material tumbles to promote agglomeration. Much like the disc pelletizer, binder and feedstock are …

A process for continuously forming balls from communited solids, comprising: (a) adding a controlled amount of liquid to a moving mass of communited solids, (b) feeding said wetted solids into a moving balling device wherein said solids are formed into balls having a surface liquid content, (c) removing said formed balls from said balling device,

Rotary Drum Agglomerators are machines used to bring together fines in the presence of moisture via a large rotating drum. Drum agglomerators, also sometimes known as balling drums or rotary granulators, are …

The balling drum or pugging drum are much the same in operation, in that they both depend upon the tumbling action of a revolving drum to mix and ball up the material during its passage through the drum. ...

A binder, usually powdered bentonite, may be added to the concentrate to improve ball formation and the physical qualities of the "green" balls. The bentonite is mixed with the carefully moistened feed at 5 to 10

In a continuous balling process, which may be the formation of green balls from iron ore, water and a binder in a balling drum as a stage in the pelletizing of iron ore, which includes a balling circuit in which undersized balls are recycled directly together with further raw material, the phenomenon known as surging is reduced by a method which involves …
