What is Graphite Vibrating Sieve?

Graphite vibrating sieve, also called ultrasonic vibrating screen, it is the key equipment to solve the screening problems of fine powder, ultra-fine powder, high static electricity and easy to be agglomerated materials by using ultrasonic technology in graphite industry. Through the vibration head will be transformed into high-frequency sinusoidal oscillation wave, transferred to the resonator, so that the resonator resonates, and then the resonator will be vibration uniformly transmitted to the screen surface. The material on the sieve is vibrated by low-frequency three-dimensional vibration and superimposed with ultrasonic vibration to complete the sieving, solving the sieving problems of lithium anode materials, high purity graphite, expanded graphite and graphite sealing materials.

Graphite Vibrating Sieve Solution in Graphite Industry

The Graphite Vvibrating Sieve (ultrasonic vibrating screen) solves the following key problems by applying high-frequency (usually 36kHz or 38kHz), low-amplitude mechanical ultrasonic vibration energy directly to the screen surface, resulting in tens of thousands of precision micro-vibrations per second:

Mesh clogging: high-frequency ultrasonic vibration to destroy the graphite powder in the mesh formed in the ‘bridge’ structure, breaking the particles embedded or stuck, eliminating the capillary effect and mechanical embedding, so that the mesh continues to open.
Breaking the agglomeration: ultrasonic energy generated by the intense acceleration directly on the agglomerated particles, effectively solving the graphite particles between the van der Waals force, breaking up the adsorption of the material into clusters, so that it is fully dispersed and uniform contact with the screen mesh, rapid passage through the screen mesh.
Inhibit electrostatic adsorption: the electrostatic charge generated by the friction of high-frequency micro-vibration with graphite particles continuously eliminates the electrostatic adsorption effect of the material on the sieve mesh, sieve frame and the wall of the equipment.
High-precision screening: By solving the three major problems of clogging, agglomeration and static electricity, ultrasonic vibrating screen maintains the effective screening area, so that the materials are strictly classified according to the particle size, and ultra-high precision can be achieved, such as up to 500 mesh or even finer particle size control.
Increased screening efficiency and capacity: Frequent downtime due to clogging and static electricity is eliminated, allowing the equipment to run continuously and stably, which significantly increases capacity and screening efficiency.
Eliminate the risk of contamination: The closed design eliminates the need for manual knocking to clear the screen or frequent contact with the material, eliminating the introduction of metal impurities or accidental damage to the screen, which greatly improves the product purity of sensitive materials such as high-purity graphite.

The graphite vibrating sieve is designed to provide efficient, accurate, stable and clean particle size classification solutions for the demanding screening needs of lithium anode materials, high purity graphite, expanded graphite, graphite sealing materials and so on.

Advantages of Graphite Vibrating Sieve in Graphite Industry

Graphite vibrating sieve has the following advantages in graphite industry screening:

Solve the ultra-fine problem: efficiently screen fine powder and ultra-fine powder such as -500 mesh or even finer, which are difficult to be processed by ordinary vibrating sieve.
Solve the adhesion and anti-clogging: ultrasonic high-frequency vibration acts directly on the screen mesh, which strongly breaks the adhesion of materials and eliminates the clogging of mesh holes.
Solve the high static electricity: effectively neutralise the static charge carried by graphite powder, solve the problem of material agglomeration, clustering and screening efficiency decline due to electrostatic adsorption.
Solve the agglomeration and stratification: ultrasonic energy disperses the material agglomerates, so that the material is evenly distributed on the screen surface.
Guarantee high purity: no mechanical hammering, to avoid the risk of metal contamination, especially suitable for high-purity graphite, anode materials and other applications that require extremely high purity.
Enhance screen life: Reduce the friction and impact of materials on the screen, effectively prolonging the service life of the screen.

Application Scenarios in Graphite Industry

Graphite vibrating sieve is often used in graphite industry for fine screening in multiple production processes:

Lithium-ion anode materials: powder before and after graphitising, artificial graphite, natural graphite micropowder particle size control and grading.
High purity graphite powder: used in semiconductor, nuclear industry and other fields of high purity graphite powder final screening and debris removal.
