Raw Materials and Processing Equipment of Spherical Graphite

Spherical graphite This graphite product is made from high-quality natural flake graphite. It also contains advanced processing technology that allows for graphite products to be produced with different levels of fineness and elliptical shapes. Spherical graphite has excellent electrical conductivity, crystallinity and low cost.
Spherical graphite Process principle: Pulverize natural flake graphite into a fine powder size. Then, perform the de-angularization process to make it ellipsoid, or spherical. Separate the fine powder that is left over from the processing to obtain the normal distribution of the spherical Graphite.

For selecting criteria Materials for spherical graphite:

You should choose the correct particle size for your spherical graphite material. To avoid high costs, the particles should be small enough to not cause problems. Finer particles will have a lower yield and can also affect the price of the raw materials. A lot of products may increase the cost of the raw materials. Study have demonstrated that it is better to use raw material with a particle size between 100 and 200 mesh for spherical graphite production.

A very important aspect of spherical Graphite raw materials is their carbon content. A higher carbon content means that raw materials are more expensive. The lower the carbon content the equipment will need to be purified. This will increase wear on the equipment and increase overall cost. It is composed of 95%96% raw materials and has the lowest comprehensive cost after accumulation.

The following criteria are used to select the spherical Graphite Processing Equipment:

Airflow vortex pulverizers are more used for spherical processes. They have both the power of pulverization as well as the de-angularization effect. It is important to consider the quality and reliability of the equipment that grades spheroidized Graphite.

High purity standards for graphite materials used in lithium-ion batteries can often exceed 99.95%. Purification is an essential part of every step in the production process. Chemical purification is the most common method of producing high-purity graphite. Since the raw materials for the chemicals used to make the graphite are strong acidic, it's important that the equipment be resistant to acids and resist corrosion. Chemical purification must be completed at a particular temperature. The equipment should also have a high resistance to heat.

After chemical reactions, impurities found in spherical graphite dissolve in reaction solutions. The impurities are then removed by washing. Mainly, the washing equipment is a centrifuge or filter press. There are many benefits to the filter press, such as a higher recovery rate and lower running material, low labor intensities, safety and simple operation. But, there is a downside: the washing result is poor and dead corners cannot be washed. While the centrifuge offers more washing power and a more effective wash, its disadvantages include a greater amount of water waste, large amounts of material running and high labor intensity. It is possible to combine the two.

After being washed, the spherical Graphite is dried in order to eliminate moisture. It is also controlled at a level below 0.5%. The most common problem with drying is secondary pollution. That is, once the spherical carbonite has been washed, it is dried to remove moisture. It is then made into a substandard product by the addition of impurities. Drying equipment such as the drying furnace, dryer, and microwave dryer are all used.
