The grinding process is carried out in a closed system, which is equipped with an air separator to separate cement particles according to size, and materials that are not completely finely ground are relayed through the system. This energy-intensive process requires automation and optimized control to ensure current quality requirements.
Cement mill separator, or cement separator, is a type of equipment that was widely used in the cement grinding system and raw mill system of cement plants.The function of the separator is to separate the fine-sized particles from the coarse-sized particles, so as to avoid material condensation and over grinding in the mill, and improve the milling system's grinding efficiency.
After grinding with the 150-grit diamond, you must apply a chemical hardener to densify the concrete surface. Now you can start the polishing. Start with a 100- or 200-grit resin-bond diamond, or a combination of the two. After that, polish with a 400-grit resin-bond diamond. Then you may proceed to also polish with an 800-grit resin-bond diamond.
