Both ball milland rod mill are very important equipment for material grinding with large capacity and wide range of applications, which can grind a variety of materials. How to choose the suitable type when buying grinding equipment? We will make an analysis and comparison between these two types.

Difference between Ball Mill and Rod Mill

1.       Grinding Media

The grinding media of ball mill is composed of a ball-shaped material, while the grinding media of rod mill is composed of a rod-shaped material.

2.       Shape Ratio

The ratio between cylinder length and diameter of ball mill varies greatly, but the ratio among various models has no much difference, generally not more than 1. However, the ratio between rod mill cylinder length and diameter is generally 1.5-2.0. The appearance of ball mill and rod mill has some differences.

3.       Material Processing Ability

The grinding fineness between ball mill and rod mill is different. The grinding media of rod mill and the material is the linear contact, large grinding area, product size uniformity. For the coarse grinding of the material, rod mill output is higher, but the fineness of finished products by rod mill is lower than the same specifications of the ball mill. Ball mill will be more suitable for fine grinding of the material.

The Advantages of Cement Mill and Rod Mill

Ball Mill

1.       The driving device of ball mill matches with the energy consumption when grinding, which can greatly reduce the system's energy consumption.

2.       The discharge port and feed port are in a rational allocation, not only increased the intensity of the feed, but also increased the amount of discharge, the production capacity of entire system is doubled.

3.       The main bearing uses a double row of self-aligning stick support, reducing the friction between the bearings, reducing energy consumption, shorten the start-up time of the system significantly, easy to start.

Rod Mill

1.       The finished product by rod mill is uniform, good shape, high yield. Compared to the old equipment, it will save more than 40% energy consumption.

2.       It adopts advanced control technology out of material. Changing the traditional surface contact grinding to linear contact grinding, the grinding the material output increased by 50%.

How to choose between ball mill and rod mill?

1.       According to the product size

When used for fine grinding, the particle size of the product is less than 0.5mm, the cement mill grinding effect is greater than the rod mill. When used for coarse grinding, the product size of 1-3mm, the processing capacity of the rod mill higher than cement mill. The feed in size of rod mill is generally 15-23mm.

2.       According to the type of material

Rod mill can be applied to different hardness (Mohs hardness 5.5-12) ore, materials. The application of ball mill is smaller.

According to the application, grinding methods, the ball mill and rod mill will be applied for different materials grinding. The user can choose the suitable type according to the actual production requirements.
