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.

Ball mill machine has always been the main grinding equipment in wet cement production. In the early years, the rod mill was first used in cement raw meal grinding, which increased the output of the grinding section by 31%, saved energy by 27%, and reduced the consumption of grinding media by 47%.

The difference on grinding medium is the main difference between the ball mill and rod mill. There is point-to-point contact between the ball mill with the steel ball, while there is line-to-line between the rod mill and steel rod. So, the working characteristics of the ball mill and rod mill are different. 4.

Difference Between Sag Mill vs Ball Mill - mech4study. · Today we will learn about difference between sag mill vs ball mill. A mill is a machine by which solid or hard materials are broken into smaller pieces by means of grinding, crushing or cutting. This commutation is an essential part of many

In this example, the OWi of the SAG mill was found to be 30% higher than the ball mill, thus suggesting that the SAG mill was less efficient than the ball mill. The apparent inefficiency of SAG mills when using Bond analysis is widely understood to be due to the difference in the slopes of the size distributions.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

In the SAG mill, the collisions with large energy acting on the ore mainly occur in the toe area, where the dropped steel balls and ore with high kinetic energy hit the ore and liner. As shown in Fig. 12c, the collision frequency between ore-ore and ore-media in the SP grinding system is similar in Range C (> 0.6 J). However, in the PH-SP ...

The Bond Rod Mill Grindability Test is performed similarly to the ball mill test. The feed sample is stage-crushed to ½" and the test is run under a circulating load. As in the ball mill test, the test can also be closed with various sieve sizes, but for AG/SAG mill analyses the standard 14-mesh (1.18 mm) sieve is typically used.

Where the SMC Test® is used to estimate values of A and b (used in the JK AG/SAG mill model) a so-called "Size Scaling " factor may be required. The relationship between the DWi and the JK rock breakage parameters A and b makes use of the size-by-size nature of rock strength that is often apparent from the results of well controlled tests ...

This causes the ball to break and make smaller particles. SAG mill: SAG is the short form of semi autogenous grinding. The difference between autogenous and SAG mills is, it uses balls to grind like ball grinding mill. SAG mills have built-in lifting plates inside the drum.

The difference between autogenous and SAG mills is, it uses balls to grind like ball grinding mill. SAG mills have built-in lifting plates inside the drum. When the drum rotates, the lifting plates lift the materials and the balls to the top and release them back to the surface. It causes the materials to mix at a primary level.
