Ball/Rod mill Literature . The Ball/Rod mills are meant for producing fine particle size reduction through attrition and compressive forces at the grain size level. They are the most effective laboratory mills for batchwise, rapid grinding of mediumhard to very hard samples down to finest particle sizes.
The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.

Now the mill steel ball on the market can be divided into two types according to the manufacturing process technology: Casting and forging. But the wear degrees are not the same. Due to crushing, ball need good wear resistance and toughness, which usually made of alloy steel, high manganese steel, cast iron and other materials and with forged or casted onceforming method.
Ball and tube mills. A ball mill is a pulverizer that consists of a horizontal rotating cylinder, up to three diameters in length, containing a charge of tumbling or cascading steel balls, pebbles, or rods.
A comparison of wear rates of ball mill grinding Journal of Mining and Metallurgy, 52 A (1) (2016 ) 1 10 # Corresponding author :
Rod 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.
The specific rates of breakage of particles in a tumbling ball mill are described by the equation S i = ax α i (Q(z), where Q(z) is the probability function which ranges from 1 to 0 as particle size equation produces a maximum in S, and the particle size of the maximum is related to ball diameter by x m = k 1 d variation of a with ball diameter was found to be of the form ...
HORIZONTAL/ TUBE / BALL MILL. A ball mill is a type of grinder used to grind and blend materials for use in various types of industries. A ball mill works on the principle of impact: size reduction is done by impact as the balls drop from near the top of the shell.
