Figure 8.2 shows a flow sheet where the rod mill is in open circuit and the ball mill is in closed circuit with a classifier. This is a normal set-up as the primary function of a rod mill is to provide a uniform sized feed to the ball mill. Figure 8.3 shows that the rod mill product is classified and a more uniform feed size is, therefore, discharged to the ball mill whose primary function is ...
Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture. ... rod mills, how they function - mine . Wet grinding rod mills are normally used in ...

There are many double lines finishing mills for wire rod mills in China. They are driven by AC motors in groups and rolled by multi-groove parallel rolling with the enclosure. When rolling, the rolled parts are twisted and tipped. The rolling speed is more than 15-20 m/s and the weight of the disc is less than 160 kg.
Negative tolerances (In sectional weight). No variation in dimensions throughout the length of the rod. Uniform physical properties. Uniform weight with nominal variation between middle and back end. For achieving these demanding requirements, many important features are incorporated in the modern wire rod mills. Some of these are described below.
The Bond Index conforming rod charge consists of: 6 rods of 1.25" diameter and 21" length. 2 rods of 1.75" diameter and 21" length. The grinding jar for the Bond Index Rod Mill is 12″ x 24″ in size and has a wave-shaped design. At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill.

SPEED MEETS FLEXIBILITY Single-strand high-speed wire rod mills from SMS Meer roll small sizes with high production rates – up to 120 m/s are possible. Even at full speed, the mills achieve a very good laying pattern, while tempera-
Rod Mill Function In Iron Ore. Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles. citation needed But note that the term rod mill is also used as a synonym for a slitting mill which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals.

Step 1: Make the New Screw. 6 More Images. To replace the old set screw, we need to cut the new screw to length, drill a hole on each end and tap the holes for M6 screws. I drilled the first hole before cutting the M10 rod to length, since a longer …
The finesse of the material milled by the ball mill is 0.074mm-0.4mm, only except for the two small ball mills that have a wider range of 0.075-0.89mm. However, the rod mill fine grinding fineness is about 0.833-0.147mm. In terms of the fineness of the ground material, the ball mill has a finer handling ability.
The reason why rod mill is called rod mill is that its grinding medium is steel rod, while the grinding medium of ball grinding mill is steel ball. Because the shape of the grinding media is different, the working mode has its own characteristics. When the steel rod is in motion, the gap between the rods is a regular long strip, which plays a ...
