application area
By setting the ratio of the rotation speed of the grinding bowl to the revolution speed, P4 can accurately simulate various force situations. Obtain the best repeatability in the grinding process, achieving results that other planetary grinders cannot achieve. It is an idealized and suitable grinding machine for various mechanical activations and mechanical and gold grinding. Mainly applied in the field of materials research, as well as any field that requires a powerful and innovative grinding machine.

Working principle
The rotation rates of the P4 grinding bowl and support disk can be independently adjusted, and the transmission ratio between the rotation of the grinding bowl and the revolution of the support disk can be freely set as needed. When the grinding ball moves inside the grinding bowl, its trajectory depends on the rotation rate, and the impact force and angle depend on the rotation rate and transmission ratio. By changing the rotation rate and transmission ratio, different high-energy frictional and impact forces can be generated to achieve different grinding processes with different effects. 􀂄

Design Features
􀂄 Freedom to choose and control the rotation rate and transmission ratio of the grinding bowl and support disk, allowing for unlimited changes in grinding conditions
􀂄 Control grinding time, intermittent time, and cycle mode through the RS323 interface using professional operating software
􀂄 Can rotate in the opposite direction and provide overload protection by adjusting the rotation rate
A well ventilated grinding chamber ensures sufficient cooling of the grinding samples
􀂄 Film protected keyboard with user-friendly interface settings

advantage
􀂄 Can achieve ultrafine powder grinding with final particle size<<1 μ m
The transmission ratio of the self rotation and revolution speed of the grinding bowl can be adjusted arbitrarily, which can simulate the grinding process of various ball mills under different grinding parameters
􀂄 Can be filled with inert gas for grinding

attachment
GTM gas pressure and temperature measurement system
The GTM system can transform this grinder into an analytical measurement system, which is the only system in the world that can continuously monitor gas temperature and pressure changes during the grinding process. Data can be directly transmitted to a computer through wireless transmission and reception, and displayed in the form of Excel spreadsheets and graphics.
Grinding with inert gas filling
When using a special grinding bowl lid, the sample can be ground under inert gas protection. This cover with fast ventilation inlet and outlet valves can be used in conjunction with an additional internal locking system specifically designed for inert gas filling in grinding to achieve the transfer of grinding bowls and operation of glove boxes.
