Why do powders hang up, stick to the wall and false welding in ball mill?
Powder agglomeration and dispersion of particles in the medium of the two directions of the opposite behavior, especially fine and ultrafine particles, in the gas or liquid phase particles due to the interaction force and the formation of polymerization of the state is called agglomeration, the particles are not interrelated with each other, can be free to move in the state is called dispersion.
Agglomeration is a state in which the surface area of primary particles connected by faces is much smaller than the sum of their individual particle compositions, and it is very difficult to re-dispersed in this state.
Attachment refers to the point, the angle of contact with the primary particles or small particles in the attachment of large particles, its total surface area than the cohesion of the body is larger, but smaller than the sum of the composition of individual particles, in the dispersion of easier. Coalescers and agglomerates are also known as secondary particles.
Flocculation is a more loose structure generated due to the increase in the surface area of the system, the increase in surface energy, in order to reduce the surface energy. Generally due to the bridging effect of macromolecular surfactants or water-soluble macromolecules, the particles are strung together into a loose structure like cotton wool clusters, in this structure, the distance between the ions is much larger than the cohesion or agglomeration.

What Are The Different Types Of Lab Ball Mill?
There are four common types of balls mills
| Planetary Ball Mill | Planetary ball mill is a powder processing equipment for laboratory or small batch production. When the turntable rotates, the center axis of the ball milling jar makes planetary motion, and the grinding balls in the jar grind and mix the samples in high-speed motion. |
| Stirred Ball Mill | The Stirred Ball Mill is a device for pulverizing, mixing or dispersing materials by means of grinding media driven by a high-speed rotating agitator. |
| Vibration Ball Mil | Vibrating ball mill utilizes electric motor to drive the vibration generator to produce continuous vibration, so that the cylinder body does small amplitude, high frequency continuous movement. Due to the self-rotation and relative motion of the grinding medium in the cylinder, the material in the cylinder is continuously crushed, stripped and ground into uniform powder. |
| Roll ball mill | The roller ball mill utilizes the principle of rolling and friction to make the grinding ball rotate in the grinding drum, and produce friction with the surface of the workpiece to be ground to achieve the grinding effect. |
Roll ball Mill Vs Planetary Ball Mill Vs Vibration ball mill
| Roll ball Mill | Planetary Ball Mill | Vibration ball mill |
| The running part of the roll ball mill is a rotatable cylindrical drum. When the equipment is running, the drum will bring the grinding balls inside to the top of the drum, and then the grinding balls will fall down freely because of their own gravity and smash the materials. | The planetary ball mill has a high-speed rotating circular disk, on which there are four uniformly mounted tanks, in which sealed ball milling jars can be placed, and grinding balls and materials are put into the ball milling jars. When the equipment is in operation, the main wheel rotates at high speed, and the canisters drive the ball milling canisters to rotate in the opposite direction, and the grinding balls inside the canisters are endowed with huge grinding energy under the superposition of the two rotating in opposite directions, and the samples are impacted, squeezed and rubbed. | Vibrating ball mill is driven by the vibrating mechanical structure to carry out the movement of the ball mill jar, which is divided into two-dimensional vibrating ball mill and three-dimensional vibrating ball mill. When the equipment is in operation, the ball mill jar fixed on the mechanical structure is brought to action by high frequency vibration, the grinding balls in the jar impact, extrusion and friction on the sample, which produces more grinding energy than the planetary ball mill. |
VRM Vs Ball Mill
| Vertical Roller Mill | Ball Mill |
| Vertically mounted grinding disk with multiple rollers, the material is crushed and pulverized on the grinding disk by the pressure and shear force of the rollers. | Horizontally rotating cylinder filled with grinding media, when the cylinder rotates, the grinding balls grind the material through the impact and rolling friction generated by the free fall. |

| Grinding Mill | Ball Mill |
| Broadly refers to all the equipment used to crush and grind materials, such as high-speed rotating blades, hammers, grinding discs or grinding rolls, etc. directly on the material to apply shear force, impact or extrusion force, grinding materials. | Belongs to a subdivided type of grinding machine, the core feature is to use the grinding media in the cylinder to crush the material by impact and friction. |
Wet Ball Milling Vs Dry Ball Milling
| Wet Ball Milling | Dry Ball Milling |
| It refers to the material moisture content of more than 50%, the raw material is suspended in the carrier liquid stream for grinding, and appropriate addition of dispersants and other additives to help the grinding process. Smaller level particles can be obtained, but the production cycle is long, the post-treatment is complicated and the cost is high. | It means that the moisture content of the material does not exceed 4% when the grinding operation is carried out. The production cycle is short, the post-treatment is simple and the cost is low. However, the powder in the grinding process is easy to agglomerate, and it is difficult to obtain smaller grade powder. The temperature of powder in the grinding process is easy to rise. |
