Four Advantages of Grinding Quartz Sand with a Rod Mill

Grinding equipment can be said to be the core of the beneficiation plant. Rod mills and ball mills belong to the same grinding equipment, but for processing different materials, it is still necessary to be cautious in the selection of the two. For example, our protagonist today: quartz sand, in the selection of grinding equipment, it is more inclined to rod mill heavy machinery, why is this? Next,  CIC rod mill manufacturer will introduce to you the four advantages of the quartz sand rod mill in processing quartz sand.

1. The particle size of the quartz sand produced by the rod mill is controllable

One of the reasons for choosing a rod mill instead of a ball mill is the particle size of the finished product. For the output particle size of quartz sand grinding, it is usually between 40 mesh and 120 mesh. It can be said that the particle size is not very fine. So we have to choose the rod mill, because the steel rod of the heavy industrial equipment of the rod mill is in surface contact with the material.

2. Rod mill grinding also has scrubbing function

In the purification process of quartz sand, a very important step is scrubbing, to wash off the impurities on the surface of the quartz sand, and then sort and purify. The use of a rod mill to process quartz sand can also play a role in scrubbing to a certain extent, helping to remove some impurities, which can be said to kill two birds with one stone.

3. The grinding particle size of the rod mill is more uniform

The quartz sand rod mill is manufactured by advanced technology, adding the technology of controllable discharge, and matching with appropriate grinding body, it can make the particle size of the discharge more uniform.

4. Rod mill grinding effect is better

The rods of the quartz sand rod mill have a screening effect on the quartz sand during the movement, so that large particles can be lifted to the top of each layer and concentrated to the place with strong crushing capacity for crushing. Therefore, the efficiency of the rod mill for silica sand crushing is high, and the power consumption is low.

The rod mill is driven by the motor through the reducer and the surrounding large gears or the low-speed synchronous motor directly through the surrounding large gears to drive the cylinder to rotate. The cylinder is equipped with an appropriate grinding medium - steel rods. Under the action of centrifugal force and friction, the grinding medium is lifted to a certain height and falls in the state of throwing or cascading. The material to be ground continuously enters the inside of the barrel from the ore feeding port, is crushed by the moving grinding medium, and is discharged out of the machine through overflow and continuous ore feeding force to carry out the next stage of operation.

Combining the above four advantages, it can be seen that the quartz sand rod mill has more advantages than the ball mill when grinding quartz sand and other materials that do not require high output particle size. The one that is suitable is the better one, so the choice of grinding equipment cannot be generalized, let alone generalized, and a reasonable choice must be made after multiple considerations.
