Dual-power Centrifugal Bead Mill For Nanoscale Material Grinding
Design Concept
The design of dual-power nano-centrifugal sander adopts the form of dynamic rotating centrifugal settling and discharging system, in order to respond to the demand of breaking micron and sub-micron particles to nanoscale in recent years, and the particle size of nanoscale particles is required to be stable. Distribution provides efficient production capacity; The principle is to separate the dynamic separator from the original grinding rotor, and realize the independent drive and control of the grinding rotor and the dynamic separator system through the independent driving device, so that the grinding fineness is finer, and can support the stable operation of 0.05mm grinding medium, and ensure the stability of grinding.
The centrifugal rotary separation system is driven by an independent motor. When the machine is running, due to the centrifugal force generated by the grinding system running at high speed, most of the grinding media is distributed around the grinding cavity, forming a uniform grinding layer and moving in the same direction. A small amount of material and grinding medium is rotated around the rotary separator. When the separator rotates at high speed, the centrifugal force on the zirconium ball is greater than the pressure generated by the pump on the zirconium ball in the cavity. The zirconium ball was ground in the grinding chamber while the separator was rotated.
The centrifugal force generated by the high speed rotation on the material is less than the pressure generated by the pump to force the material out.
Structure Description
Grinding system materials can be selected according to material characteristics and requirements;
The dual dynamic structure is developed on the basis of rod and pin sand mill, and the rotary separation system is a technological leap of ultrafine powder separation based on fluid mechanics, so as to realize the real nanoscale classification and lay the foundation for the efficient preparation of nanoscale powder.
Users can simply adjust the operation parameters of grinding rotor and rotation by independent driving motor to solve the adjustment of different production processes. If the grinding medium with different fineness, different linear velocity and different grinding temperature can be used, it can be grinded with large flow rate and high linear speed, and it can also be gently dispersed.
However, from the point of view of hydrodynamics, the slurry can overflow the material through the hollow shaft by centrifugal force and pumping pressure, which avoids the common clogging and residual phenomenon in grinding.
