Introduction of Bead Mill
The bead mill, also referred to as the sand mill, is a kind of milling equipment used for particle size reduction and dispersion of solid particles in a liquid medium. The working of a bead mill is based on intense agitation and grinding between the solid particles and the grinding media (beads) within a cylindrical chamber. The chamber is typically filled with grinding beads made of materials such as zirconia, ceramic, or metal. There is an agitator in the chamber, usually in the form of a rotating shaft with discs or pins attached. Its high-speed rotation generates a strong turbulent flow within the chamber, causing the grinding beads and the material to collide and interact.
As the material is fed into the mill from one end, it is subjected to the high shear forces generated by the agitator and grinding beads. This intense agitation breaks down the particles, reducing their size and promoting dispersion. The grinding beads effectively grind and disperse the material, ensuring a uniform particle size distribution in the final product.
Compared with similar products from other competitors, SeFluid’s bead mill series are cost-effective and easy to maintain with an economic price that customers can afford but can achieve nano-level grinding fineness. In many fields such as coatings, rubber, pesticides, cosmetics, etc., SeFluid’s bead mills are widely used and widely welcomed by users.

Principle of Bead Mill
There are a group of cylindrical agitating rod pins installed on the hollow rotor shaft. These pins work with the horizontal ceramic shell to form a high-density energy grinding chamber. There are different materials for the pins according to different material properties. When running, the hollow stirring shaft drives the rod pins to do high-speed operation. Then, the rod pin drives the medium to carry out fierce collision and grinding. Therefore, the medium experiences strong impact force and high shear force. After that, good milling and dispersing effect will be achieved.

Ventaja de la serie SESM Bead Mill
Cilindro de fresado interior de carburo de silicio

En la serie de molinos de bolas de SeFluid, tomamos cerámica de carburo de silicio como material del cilindro de molienda. Se sinteriza durante muchos días a altas temperaturas. Como la dureza del carburo de silicio solo es superada por la del diamante, es altamente resistente al desgaste y duradero. Mientras tanto, tiene alta resistencia, alta dureza, excelente resistencia al desgaste y a la corrosión y buena resistencia a la temperatura (-50 ℃ a 1350 ℃). Además, la superficie lisa de la cerámica de carburo de silicio puede evitar la acumulación de polvo. Por lo tanto, es un material ideal para el fresado de piezas.
Conjunto de fresado de larga duración

Rotor assembly is one of the key parts of an agitator bead mill. It is also the final kinetic energy conversion device. Due to the high speed of rotation, the rotor assembly must be highly resistant to fatigue, corrosion and abrasion. Therefore, it is made of special materials and subjected to many rigorous tests, depending on the customer’s material requirements. This ensures that our bead mill series achieves consistent and efficient grinding performance. For all SeFluid’s bead mill products, we have various wear resistant materials for user’s options ranging from ceramic to hard alloy.
Cartridge Mechanical Seal Adopted

Modular design is adopted in the use of cartridge mechanical seals, where the seal module is directly installed on the bead mill shaft during installation. During maintenance, only the seal module needs to be disassembled, without the need to dismantle other components such as bearings. This greatly simplifies the installation process and reduces maintenance costs.
When a bead mill is in operation, a large amount of grinding fluid is generated. If the seal is not tight, it can lead to leakage of the grinding fluid, which can affect the normal operation of the equipment and even cause safety accidents. Moreover, the grinding fluid can enter the bearings, resulting in damage to the bearings. Cartridge mechanical seals have excellent sealing performance, effectively preventing leakage of the grinding fluid, protecting the normal operation of the bearings, prolonging the service life of the equipment, and reducing operational costs.
Sistemas de refrigeración de alta eficiencia

Es necesario un buen enfriamiento para garantizar el funcionamiento estable a largo plazo de un molino de bolas. Si las grandes cantidades de calor no se eliminan a tiempo, el sello mecánico y las piezas de fresado pueden dañarse. Mientras tanto, el material molido también puede cambiar sus propiedades físicas o químicas debido a la alta temperatura. En la serie de molinos de perlas de SeFluid, hemos diseñado especialmente dos sistemas de enfriamiento eficientes. En primer lugar, hay un sistema de refrigeración por circulación de aceite para los sellos mecánicos. En segundo lugar, hay un sistema de enfriamiento de camisa para el cilindro de molienda. Además, el sistema permite a los usuarios realizar un seguimiento del aumento de temperatura.
