What is the difference between a sand mill and a ball mill? The following is from Dongguan ball mill manufacturers small editor to explain in detail for everyone.
The grinding machine belongs to the wet ultra-fine grinding equipment and is developed from the ball mill. It is widely used in the production process of ultra-fine powder(sub-micron powder). Grinders have different classification methods: according to the structure of the mixing shaft can be divided into disc type, rod type, rod plate type(both convex block type). According to the layout of the grinder, it can be divided into vertical and horizontal. According to the volume of the cylinder, it can be divided into laboratories, small, medium, large, and super large.
The ball mill is not the same as the grinding principle, grinding fineness and application field. The vertical mixing mill, after all, has an independent energy input without the use of Earth's gravity, which can be considered as a technological revolution in grinding equipment. Due to the low speed, medium size, and speed gradient along the pin rod, mixing mill has a low grinding efficiency and wide product size distribution. Therefore, the mixing mill is gradually squeezed out of the market by the grinding machine and is now only used for cemented Carbide, ferrite grinding or pre-grinding.
First, the progress of the grinding medium separation system with the continuous improvement of product fineness requirements, the size of the use of grinding medium is getting smaller and smaller. The separation of small scale grinding medium is one of the most difficult problems in the research and development of grinding machine. The gap ring(small overflow area) and the static screen used by the traditional sand mill are difficult to separate from the small size medium. So more and more dynamic centrifugal separation systems are used. The centrifugal force generated by the separation of the rotor leading to the rotation of the medium causes the medium to be thrown around the outside of the rotor, while the center of the rotor is mainly a slurry, and the separation screen is arranged in the center of the rotor, and the material will flow smoothly through the gap of the screen. There will be no clogging and wear. Therefore, it is a technological leap in the history of the development of grinding machine to apply dry air classification principle to the media separation of grinding machine.
The Appearance of Horizontal Centrifugal Grinder
In the past period of time, the main grinding machine manufacturers at home and abroad are one-sided; To increase product fineness(reduce particle size), it is necessary to increase the energy density of the grinding machine. As a result, there have been a number of complex structure of the pin grinding machine. After years of misguided and artificially complicated grinding machine design, people finally began to simplify. Because the real grinding of the material only occurs in the grinding area with a certain energy density, the low-energy area is only hot. High energy density area can only appear in the outer ring area with the largest online speed. Based on the results of this study, centrifugal grinding machines have emerged. Centrifugal grinders can concentrate more materials for grinding in high energy areas, and the grinding efficiency is greatly improved.
