What is the cold knowledge to be aware of in bead mill selection?
Bead mill is a commonly used industrial equipment, which is widely used in various industries, such as paint, ink, pigment, ceramics, glass, chemical and other fields. The working principle of bead mill is mainly to grind and mix the materials through grinding media to achieve the required fineness and uniformity. In this article, the type, working principle, grinding media and grinding efficiency of bead mill will be introduced in detail.
Bead mill can be divided into two categories according to the structure: horizontal bead mill and vertical bead mill. Horizontal bead mill is a commonly used bead mill, its working principle is to use the high speed rotating agitator to throw the grinding media to the cylinder wall, and then the material is ground and agitated by friction and impact. Vertical bead mill is a new type of bead mill, its working principle is through the up and down reciprocating movement of the stirring rod to stir the material, at the same time using the action of the grinding media to grind the material to the required fineness..
Grinding media is a very important part of the bead mill, and its material and size have a great influence on the grinding efficiency and product quality. Commonly used grinding media are glass beads, zirconium silicate beads, aluminium oxide beads and steel beads. Different grinding media are suitable for different material characteristics and product requirements, so it is very important to choose the right grinding media to improve grinding efficiency and product quality.
Grinding efficiency is an important index to measure the performance of bead mill, which is affected by many factors, including the material of grinding media, particle size, filling rate, rotational speed and material characteristics. In practical application, it is necessary to choose suitable grinding media and process parameters according to different material characteristics and product requirements, in order to achieve the best grinding effect.
In addition, in order to improve the grinding efficiency, multiple bead mills can also be used in combination by means of series connection, so that the material is ground and stirred by multiple bead mills to achieve finer particle size and better uniformity. At the same time, you also need to pay attention to the maintenance and repair of the equipment, regular inspection and replacement of grinding media to ensure the normal operation and service life of the equipment.
As an important industrial equipment, bead mill has a wide range of applications. Understanding the type of bead mill, working principle, grinding media and grinding efficiency will help to better select and use the bead mill to achieve better production effect and economic benefits.
