What is a planetary machine


1. The double-layer gear drives the planet at the bottom to rotate. While the small disc at the bottom rotates, the large disc also rotates to promote more uniform and sufficient grinding.


2. The disc segment has greater downward grasping force and higher grinding efficiency.


3. The ground grinding is smoother, which can effectively improve the wave form under the light after the ground polishing.


Concrete grinders are used for one thing – grinding concrete. They’re mostly used for putting a smooth finish on concrete, which they do quite quickly. Choosing the right concrete grinder for your purpose can make a seemingly difficult job very easy.
