PURPOSE:To breake a hydrous rubber type elastic body into a large quantity of small fragments by a method wherein two cutting mills are connected vertically, the diameter of the upper screen hole is made larger than that of the lower screen hole and air is absorbed and blasted to the lower direction through the lower screen hole. CONSTITUTION:When hydrous high molecular weight water soluble polymer (rubber type elastic body) such as acrylamide, acrylic acid, etc. is broken by a cutting mill into fragments, two cutting mills A, B are arranged up and down and connected with each other, the hole diameter of a screen 6 of the upper cutting mill A is made larger than that of the screen 6' of the lower cutting mill B and the former is 10-25mm. while the latter is 7-15mm.. The air is sucked from the lower outlet of treated fragments and made of flow in the upper and lower cutting mills A, B and the passage in the same direction as the treated dust flows. |
