Grinding Mills and Their Types – IspatGuru

09.04.2015· Maximum rod length is about 6 to 7 meters, otherwise there is a risk of the rods bowing. The drum diameter is limited to 0.6 or 0.7 times the length of the mill. Rod mills are used for grinding hard minerals. This type of mill is normally used as the first stage of a milling process to provide a reduced size feedstock for a further milling process.

Grinding control strategy on the conventional milling

(-9 mm) is fed to the rod mill, and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped, without any further water addition, to the first ball mill. The ball mill discharges to a sump where water is added before the slurry is pumped to the first cyclone (Cylcone 1). See Figure 1 for a schematic of the process flow.

Effects of mill feed size and rod charges on

01.02.1992· Using smaller rod diameter and reducing the mill feed size will optimize energy use in coarse grinding. 119 Introduction Rod grinding is widely used in many mineral processing plants performing coarse grinding, since it is more efficient than ball grinding for this purpose [1].

Small-Scale Tests to Characterise Ore Grindibility - SGS

BOND ROD MILL GRINDABILITY The Bond rod mill grindability test is performed similarly to the ball mill test. The feed sample is stage-crushed to ½" (12.5mm) and the test is run under a circulating load. The test can also be closed with various sieve sizes, but for AG/SAG mill analyses the standard 14-mesh (1.18mm) sieve is typically used.

AMIT 145: Lesson 4 Gravity Separation –

The angular velocity (ω) is often expressed in terms of the rotational speed, N. w = 2πN/60 where w = 60νr/2πr. The centrifugal force, F c, is given by: Fc = mf (2πN/60)2 = 0.01097 mrN2. Centrifugal force is often expressed in the magnitude of the force with respect to the gravitation force (g's):

Eriez - Size Reduction and Laboratory Equipment

Rod & Ball Mills. 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 batch-wise, rapid grinding of medium-hard to very hard samples down to finest particle sizes.

What are the differences between ball mill and

08.03.2021· Ball mill and rod mill are suitable for different materials. 1. Selection by material's hardness. Ball mill has a strong adaptation of material, and it is suitable for grinding hard materials, such as slag, iron ore, copper ore, etc. Rod mill is suitable for grinding brittle material, such as rare metals. 2.
