Product Introduction

The design of the dual-power nano-centrifugal sand mill is in the form of a dynamic rotary centrifugal sedimentation and discharge system, which is in response to the demand for the crushing of micron and submicron particles to the nanometer level in recent years, and requires a stable narrow particle size. The distribution provides efficient production capacity; the principle is to separate the dynamic separator from the original grinding rotor, and realize the independent driving and control of the grinding rotor and the dynamic separator system through the independent drive device, so that the grinding fineness is finer and can support to use 0.05mm grinding media to run stably to ensure the stability of grinding.

Product advantages

It can use 0.05mm grinding media for stable grinding and dispersion.

It can use 0.05mm grinding media for stable grinding and dispersion.

Unique

Unique centrifugal technology and cyclone separator structure avoid the phenomenon of material blocking and leaking balls.

The special jacket cooling layer

The special jacket cooling layer can cool quickly at high leaner speed and multiple times of grinding.

The grinding fineness is more fine

The unique grinding system grinding rotor and rod pin design can centrifuge the slurry according to different fineness during grinding to avoid finer particles continuing to participate in ineffective grinding.

Dual-power centrifugal Bead Mill Design Concept:
1.The design of the dual-power nano-centrifugal sand mill is in the form of a dynamic rotary centrifugal sedimentation and discharge system, which is in response to the demand for the crushing of micron and submicron particles to the nanometer level in recent years, and requires a stable narrow particle size.
The distribution provides efficient production capacity; the principle is to separate the dynamic separator from the original grinding rotor, and realize the independent driving and control of the grinding rotor and the dynamic separator system through the independent drive device, so that the grinding fineness is finer and can support to use 0.05mm grinding media to run stably to ensure the stability of grinding.

2.The centrifugal rotary separation system is driven by an independent motor. When the machine is running, most of the grinding media are distributed around the periphery of the grinding cavity due to the centrifugal force generated by the high-speed operation of the grinding system to form a uniform grinding layer move in the same direction. A small amount of material and grinding media revolve around the rotary separator. When the separator rotates at high speed, the centrifugal force on the zirconium balls is greater than the pressure generated by the pump on the zirconium balls in the cavity. The zirconium balls stay in the grinding cavity for grinding, while the separator is rotated.The centrifugal force formed by the high-speed rotation on the material is less than the pressure generated by the pump on the material to force the material to be discharged.

 

Structure Description:
1.Grinding system material can be selected according to material characteristics and requirements.
2.The dual power structure is developed on the basis of the rod-pin sand mill, and the rotary separation system is a technological leap in the separation of ultra-fine powders based on fluid mechanics, thus realizing the real nanoscale classification, which lays the foundation for the realization of efficient nano-scale powder preparation.
3.The user can simply adjust the operation parameters of the grinding rotor and the rotary separator through the independent drive motor to solve the adjustment of the production process of different products. For example, grinding media of different fineness, grinding at different linear speeds, and different grinding temperatures can be used, and it can be ground with large flow and high linear speed, and can also be gently dispersed.
4.However, from the point of view of fluid mechanics, the milled slurry overflows the material through centrifugal force and pumping pressure through the hollow shaft, which avoids the common blocking and residual phenomenon in grinding.

 

Advantages:
1.It can use 0.05mm grinding media for stable grinding and dispersion.
2.Unique centrifugal technology and cyclone separator structure avoid the phenomenon of material blocking and leaking balls.
3.The special jacket cooling layer can cool quickly at high leaner speed and multiple times of grinding. 
4.The unique grinding system grinding rotor and rod pin design can centrifuge the slurry according to different fineness during grinding to avoid finer particles continuing to participate in ineffective grinding.
