The difference between ball mill and rod mill

The difference between ball mill and rod mill

Ball mill and rod mill is an important tw okinds of equipment for material grinding, powerful, wide range of applications,capable of grinding a variety of materials, then in the purchase of grindingequipment,  which kinds of ball millchoose in the end? The following will be a systematic analysis.

The difference between ball mill and rod mill:

1. Grinding media

Ball mill grinding media is a ball-shapedmaterial composition, and rod mill grinding medium is made of a rod-shapedmaterial.

2. Shape ratio

Ball mill cylinder length and diametervalues vary greatly, the ratio of many types of models is not much difference,generally not more than 1, and the rod mill cylinder length and diameter ratiois generally 1.5-2.0, both the appearance of some difference.

3. The ability to handle the material

The grinding fineness of the two different,rod mill linear contact between the media and the material, grinding area,product size uniformity, the coarse grinding of the material, rod mill outputis higher, but the ball mill grinding Finished fineness to be more detailed,suitable for more fine grinding of the material.

Ball mill and rod mill advantages:

Ball mill

1. Ball mill drive and grinding energyconsumption reasonable match, can greatly reduce the system's energyconsumption.

2. The discharge port and the feed portreasonable allocation, not only increased the size of the feed, but alsoincreased the amount of discharge, the entire system doubled productioncapacity.

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

Rod mill

1. Rod mill product of uniform texture,grain shape, high yield of finished products, compared to the old-fashionedequipment, saving more than 40% energy consumption.

2. The use of advanced control technologyout of material, the traditional surface contact grinding improved line contactgrinding, grinding the material output increased by 50%.

Ball mill and rod mill how to choose:

1. According to the desired product sizeselection

When used for fine grinding, the particlesize of the product is less than 0.5mm, the ball mill grinding effect isgreater than the rod mill, when used for coarse grinding, the product size of1-3mm, the processing capacity of the rod mill higher than Ball mill. Rod millto the mine size is generally 15-23mm.

2. Grinding the type of material

Rod mill can be applied to differenthardness (Mohs hardness 5.5-12) ore, materials, ball mill range to be smaller.

Ball mill and rod mill scope, grindingmethods vary, for different materials grinding, the user can choose accordingto their actual production requirements
