In recent years, with the sharp increase in the demand for cathode materials for new energy vehicles, the price of spodumene concentrate has risen, and many lithium ore concentrators have begun to expand the production of lithium resources. In order to rationally develop and utilize lithium ore resources, it is particularly important to choose the right spodumene ball mill.

First. Introduction of Lithium Ore
Lithium ore resource is a kind of metal energy with various uses. It plays an important role in manufacturing fields such as glass, ceramics and batteries. In addition, it is also used in high-energy lithium batteries and controlled thermonuclear reactions. It is the solution for human beings to solve long-term energy supply. important raw materials.

Second. Types of global lithium mines
Global lithium deposits are divided into three types, namely salt lake brine type lithium deposits, pegmatite type lithium deposits and sedimentary type lithium deposits. Pegmatite type lithium deposits and sedimentary type lithium deposits belong to the distribution type of solid type lithium deposits. Judging from the development of the three types of lithium ore resources, the salt lake brine-type lithium ore has a high development and utilization rate and plays an important role in the production of lithium compounds.

Third. Types of lithium ore ball mills
At present, lithium ore resources are mostly extracted from pegmatite ores and salt lake brine. The process of extracting lithium from brine is simple, the recovery rate is high, the cost is low, and the environmental pollution is small. Lithium extraction from pegmatite-like ores has become an important resource for obtaining lithium resources. There are various methods for extracting lithium minerals from this type of ore, such as sulfuric acid roasting method, sulfate roasting method, chlorination roasting method, etc. However, the important link that cannot be lost before extraction is grinding. After the ball mill realizes the dissociation of the monomer, the beneficiation link can effectively extract the lithium resources. At present, the commonly used lithium ore ball mill equipment includes: lattice ball mill, overflow ball mill, long barrel ball mill, energy-saving ball mill, etc.

1. Lithium ore grid ball mill
In the lithium ore dressing plant, the grid ball mill is mainly responsible for the grinding of coarse minerals, and is mostly used in the first-stage grinding operation. Due to its special ore discharge plate design, the ball mill has a large ore discharge particle size and less blocking phenomenon.

2. Lithium ore overflow ball mill
This ball mill is different from the grid type ball mill. There is no grid plate design at the discharge place. When discharging, it mainly relies on the continuously fed pulp to squeeze the ground pulp, so that it gradually moves to the discharge section. When the pulp exceeds the overflow When the weir is flowing, the pulp is discharged. The overflow type ball mill is mainly suitable for the grinding of finer minerals in the lithium ore dressing plant, and is mostly used in the second-stage or concentrate grinding operations.

3. Lithium ore long barrel ball mill
The long barrel type ball mill has a long barrel, which is much larger than the diameter. The inside of the barrel can be set to 2 bins or multiple bins (generally no more than 4 bins). The length of each bin is determined according to the grinding conditions. The ball mill is used in lithium ore dressing. It can be used as a fine grinding operation in the factory.

4. Energy-saving ball mill for lithium ore
The energy-saving ball mill is Xinhai’s innovative new ball mill. The modified ball mill is developed and innovated on the basis of the original lattice or overflow ball mill. The energy consumption of the ball mill is reduced by about 30%; in addition, it is equipped with a large and small gear spray lubrication system to effectively reduce the problem of poor lubrication; it is equipped with a hydraulic jacking device, and the hydraulic jack can be lifted up and down by operating the handle of the hydraulic station during maintenance of the ball mill. Ensure the horizontal position of the ball mill; also customize the suitable ball mill liner according to the properties of lithium ore to ensure the wear resistance of the ball mill and prolong the service life of the ball mill.

The above content is an introduction to the characteristics of lithium ore and the commonly used ball mills for lithium ore. Ball mills are inseparable from the concentrator. As for which ball mill to choose, it is necessary to customize a reasonable beneficiation process and configure suitable ball mill equipment according to the process conditions. The efficiency of the mine is improved, and it helps the subsequent beneficiation operations to provide qualified raw materials.
