Lithium Ore Ball Mill

How to choose the ball mill model for grinding lithium ore powder in a lithium ore concentrator:

1.Select according to the properties of grinding materials

The material properties have a great influence on the production capacity of the lithium ore powder ball mill. The same model of lithium ore powder ball mill can grind graphite ore (hardness 1-2) and iron ore (hardness 4-5). The output per unit is definitely different. the same. If you are processing iron ore, then the selected ball mill model must be larger to achieve the ideal processing capacity.

2.Select according to product fineness

The fineness of the product is also related to the choice of ball mill model for grinding lithium ore powder. Generally speaking, grid-type ball mills are suitable for coarse grinding, and overflow-type ball mills are suitable for fine grinding. When it is necessary to grind uniform coarse-grained products of about 0.208~0.295mm (48~65 mesh), the grid type ball mill is better; when it is necessary to grind fine products of 0.074~0.104mm (150~200 mesh), it is better to use an overflow ball mill. Flow type ball mill; when two stages of grinding are required, the first stage uses the grid type and the second stage uses the overflow type; when coarse concentrate regrinding is required, an overflow type ball mill should be used.

3.Select according to the processing capacity of the mineral processing plant

The amount of ore to be processed by the mineral processing plant per hour determines the equipment configuration of the entire mineral processing production line, and also determines the selection of the lithium ore powder ball mill model. The processing capacity of each model of lithium ore powder ball mill has been given in the technical parameter table. , you can refer to it when choosing. Of course, other relevant factors must also be combined to determine the appropriate model.

In short, the selection of the lithium ore powder ball mill model should be considered based on many factors. It is recommended that you conduct a grinding test on the material before selecting the ball mill, and determine the equipment model based on the test results.

Lithium ore powder ball mill plays an irreplaceable role in the production of lithium ore concentrator. When the useful minerals in the ore are ground into fine particles, the ore needs to be ground very fine to dissociate the useful minerals and gangue. , reducing the grinding fineness of ore can improve the recovery rate and output of useful minerals. At present, it is difficult for simple crushing equipment to meet the requirements, and the lithium ore powder ball mill has become the key equipment to control the shipping particle size. At present, the lithium ore powder ball grinding machine has become one of the necessary equipment in the lithium ore dressing plant. What other lithium ore powder ball mills are used for entry-level grinding in lithium ore concentrators? Let’s introduce them one by one below.

Working principle of lithium ore powder ball mill:

The lithium ore powder ball mill is a device that further crushes the crushed lithium ore. Usually the input particle size is 20~30mm, and the discharge particle size should be ≤0.074mm, that is, below 200 mesh. To facilitate subsequent further selection operations. The structure of the lithium ore ball mill mainly consists of a cylinder, bearings, motor, large and small gears, inlet and outlet ends, etc. The cylinder is equipped with steel balls. When the ball mill is working, the main bearing drives the cylinder to rotate. The crushed lithium ore enters from the feed end. The rotating cylinder forces the steel balls and lithium ore in the cylinder to rotate together and collide with each other to further crush the lithium ore. Purpose.

Type of ball mill for grinding lithium ore powder:

At present, lithium resources are mostly extracted from pegmatite ores and salt lake brine. The process of extracting lithium from brine is simple, with high recovery rate, low cost and little environmental pollution. However, currently, lithium resources in salt lake brine are gradually depleted. Extracting lithium from pegmatite ores has become an important resource for obtaining lithium resources. There are multiple methods for extracting lithium minerals from this type of ore, such as sulfuric acid roasting, sulfate roasting, chloride roasting, etc. However, an important link that cannot be lost before extraction is grinding. Only by passing the pegmatite lithium ore through a ball mill Only after monomer dissociation is achieved can the mineral processing link effectively extract lithium resources. Currently commonly used ball mill equipment for grinding lithium ore powder include: grid ball mill, overflow ball mill, long barrel ball mill, energy-saving ball mill, etc.

Performance characteristics of ball mill for grinding lithium ore powder:

The lithium ore powder ball machine discharges the ore faster and is more energy-saving, about 30% higher than other ball machines, and saves about 20% of electricity. It can effectively avoid the phenomenon of over-grinding, discharge the ore at a low level, store less slurry inside, and report the fine particles that have been ground in a timely manner. There are many balls to be loaded, and ball loading can be coordinated at multiple levels. The grid can avoid steel ball notification, and the grinding conditions are good. The ball concentrator is installed and debugged before leaving the factory, which facilitates simple installation on site. The large rotating gear of the equipment is processed by casting gear hobbing, and the cylinder is inlaid with a wear-resistant lining plate, which has good wear resistance. The energy-saving and consumption-reducing effect of the lithium ore powder ball mill in the application of different ore types and different ore processes shows that: the accuracy of the ball diameter, the science of filling the balls and the accuracy of the media shape improve the probability of mineral crushing and media grinding. Efficient utilization improves mill efficiency. The energy consumption is relatively reduced. At the same time, thanks to the reduction of the sliding power consumption of the ore medium, the electromechanical consumption is also reduced, achieving energy saving and consumption reduction of the lithium ore grinding mill, and achieving significant economic benefits. Media consumption also has the dual effect of being reduced. This move also proves that the lithium ore powder ball mill is widespread, mature, reliable and practical in the application of energy saving and consumption reduction in mineral processing plants.
