Bead Mill Vs Ball Mill

At present, the Bead mill and ball mill are two different types of equipment, but in fact there is a certain relationship between them, because the bead mill is developed from the basis of the ball mill, Both are using the grinding medium between the collision, extrusion, friction and other principles of crushing materials. But there are essential differences and applications between Bead mill and Ball mill.

I、Working principle

Ball mill: The cylinder rotates at a low speed, and there is no mixer in the cylinder. The large-scale grinding ball is used, and the gravity potential energy of the grinding ball is used to cut and crush the material. When the barrel of the ball mill rotates, the grinding body acts due to inertia and centrifugal force, and the frictional force acts on the cylinder liner to be carried away by the cylinder. When it is brought to a certain height, due to its own gravity And being thrown, the falling grinding body crushes the material in the cylinder like a projectile.

Ball mill Working principle

Bead Mill: The grinding chamber is fixed, there is a mixing shaft in different ways in the grinding chamber, using small grinding medium, adopting the agitator shaft imparts kinetic energy to the medium to break up the material. There are vertical or horizontal bead mill, disc and pin and turbine Type. The fineness of the grinding can reach 100 nm or 50 nm.

II、Grinding Media Difference

Ball mill generally use steel balls and are loaded into the chamber according to different diameters and proportions. The grinding medium can also be used in steel sections. The size of the selected steel ball is generally large, usually 40mm, 60mm, etc.

Bead Mill: The grinding media of the bead mill generally uses zirconia beads, zirconium silicate beads or glass beads, which are selected according to different abrasive materials used by different manufacturers. ELE Bead mill adopt high wear-resistant alloy steel as the grinding material, its hardness can reach HRC62, so our company bead mill recommended 95% zirconia beads. Generally used size is 0.1mm~2.0mm

III、Application difference 

The ball mill is the key equipment for crushing the material after it has been crushed. Ball mills are widely used in the production of cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal dressings and glass ceramics, dry or wet grinding of various ores and other grindable materials. It is very important to grind the ball mill in beneficiation.

Bead mill are mainly used for wet grinding of chemical liquid products (paints, inks, pigments, dyes, pesticides, paints, wood lacquers, automotive lacquers, nanomaterials, cell disruption, biomaterials, battery materials, titanium dioxide, alumina, For ceramic pastes and the like, the fineness is required to be 10 μm, about 5 μm, or nanometer.

The ball mill has a low rotation speed, a large media size, and a large radial velocity gradient along the pin. Therefore, the grinding efficiency is lower and the particle size distribution is wide. Therefore, the ball mill is gradually be replaced by the bead mill, and is now only used for hard Alloy, ferrite grinding or pre-grinding.

Therefore, when choosing, it is suitable time to use the high efficiency bead mill of Shanghai ELE
