Live ChatRod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed.

Live ChatDischarging Methods of Ball Mill and Rod Mill Different discharging methods are adapted to different grinding processes. For the ball mill, we can choose the overflow type discharging ball mill and grid type discharging ball mill according to the different production requirements.

Live ChatBall Mills vs Rod Mills. When the mill is rotated without feed or with very fine feed, the rods are in parallel alignment and in contact with one another for their full length. New feed entering at one end of the mill causes the rod charge to spread at that end. This produces a series of wedge shaped slots tapering toward the discharge end.

Live ChatIn the ball mill, commonly used have the lattice ball mill and overflow ball mill (named from different drainage structure), and the rod mill does not use the grid plate drainore, only overflow type and opening type two kinds, the diameter of the hollow shaft at the drainage and end is generally larger than the same specification ball mill. Grinding media analysis rod grinders are commonly used as grinding media with

Live ChatThe energy consumed by rod mills could be from 10 to 30% higher than the energy consumed by bar mills and this is for comparable performance. A rod mill is recommended if we want to properly grind large grains, because the ball mill will not attack them as well as rod mills will.

Live ChatBecause of this, rod mills are normally operated with a 32 to 40 percent charge by volume. In operation, this becomes a 40 to 50 percent charge, with a bulk density considerably lower than that of stacked rods. Ball mill charge becomes measurably swollen only when there is a buildup of large unground material in the ball mill or when the density of the pulp in a wet mill is extremely high.

Live ChatRod Mills. The Steel Head Rod Mill (sometimes call a bar mill) gives the ore dressing engineer a very wide choice in grinding design. He can easily secure a standard Steel Head Rod Mill suited to his particular problem. The successful operation of any grinding unit is largely dependent on the method of removing the ground pulp.

Live ChatThe overall design of ball mills and rod mills are compact, with simple operation and easy maintenance. But the both are different in performance and applications. In this article, the similarities and differences between ball mills and rod mills are analyzed from 9 aspects, and suggest how to choose ball mill or rod mill.

Live Chat8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter (Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 2040% water by weight.

Live ChatSince a rod mill will accept a coarser feed than a ball mill, it fits in naturally as the intermediate comminution step. However, rod mills, like crushers, must be operated under controlled conditions to obtain maximum efficiency and are more difficult to operate than ball mills.

Live ChatBall Mills. The ore from the crushing section is delivered to the fine ore bin placed at the head of the grinding section, from which it is fed, together with water, to one or more grinding units consisting of a ball mill or rod mill in circuit with a classifier.

Live ChatTubular tumbling mills loaded with rods as the grinding media are used for primary grinding of rocks and minerals. Rods are placed parallel to the length of the mill, their length being about 150 mm shorter than the inside length of mills. The grinding action for size reduction of particles is almost similar to ball mills,

Live ChatFor details, the grinding theory of ball mill and rod are different in many ways. For ball mill, the grinding force of steel ball to ore is less than the impact, because the contact area is small between balls and mineral. Thus, the throwing motion of ball can produce a large impact, but it need a high rotate speed and has a higher power consumption.
