description of powder grinding plant

Powder Grinding plant, high frequency resonance, resonance Ultrafine powder for short, is based on the theory of high frequency resonance design of a new generation of grinding plant. It can be used in the production of various kinds of micron level, nanometer minerals. The crushing principle is: by high frequency vibration of the inertia vibrator excitation grinding cylinder in produce resonance frequency ratio close to 1 case. And nearly 50 hz frequency of 3 d circular frequency vibration. Vibrational energy in the form of shock waves by grinding cylinder is introduced into the wall of a cylinder, and produce high speed rotating flow field around a cylinder, the acceleration of the field power reaches 45 g (general vibration crushing plant only 10 g). The media and material do high-speed rotary motion along the wall. At the same time due to the effect of centrifugal force, the cylinder and the inner central district of medium and material composed wall extrusion, form a centrifugal force field. In the medium and material double under the action of force field eddy current shape is irregular movement. Materials in motion by the impact of several dozen times higher than that of the excitation frequency, shear, extrusion, grinding, refining decomposition, finally be micron grade or nano-sized particles.
The features of powder grinding plant：
1, High efficiency and energy saving. Because the main frequency is close to the resonance point, than with smaller vibration force can obtain larger vibration energy, (in theory vibration efficiency is highest when the frequency ratio is equal to and energy consumption is a small percentage of one over ten or even other plant. Crushing efficiency is dozens of times and even hundreds of other devices.
2, Nanoscale pieces. Due to the high frequency energy input (45 g) vibration intensity, produce mechanical chemistry, can make the chemical bonds between the molecules fracture in full, or change the molecular structure, nano mineral.
3, Small abrasion index. Due to the eddy current field and centrifugal force field in the opposite direction, reduces the direct grinding medium and compared.in, medium fully wrapped by material layer, the medium between direct ground to reduce risk. So the abrasion index is small, can avoid the secondary pollution of material.
4, Strong applicability. It can realize the frozen special grinding, vacuum, inert gas protection, etc.
5, Stable mechanical properties, structural strength improved significantly. It can realize frequency automatic matching, working state of automatic control.
