Description

At the same time, different perforated grinding cylinders 6 with different apertures can be replaced according to the size of the required toughening agent particles, making the use more flexible. Vertical connecting plates 8 are fixedly installed on both sides of the top of the lower connecting plate 2. An upper connecting plate 9 is fixedly installed at the top of the vertical connecting plates 8. A synchronous rotation driving assembly 10 is installed on the upper connecting plate 9.
