The price of Teflon pepper balls is the highest among all solid plastic balls. The main reason for the high price of Teflon pepper balls is that the processing efficiency is low and the cost is too high, while the processing efficiency of machine tools is basically fixed during the processing. However, the technology of grinding Teflon pepper balls with a ball grinder has great room for improvement.The surface of Teflon pepper ball is smooth, and if the number of grinding wheels used in the ball grinder is fine, the powder ground by Teflon is easy to adhere to the surface of the grinding wheel during grinding, and some even enter the pores of the grinding wheel. When there are a large number, a coating-like object is formed on the surface of the grinding wheel, and the Teflon pepper ball will not get the grinding effect when grinding. The solution is to have a thicker grinding wheel for grinding, and use special grinding liquid for cleaning and lubrication.
