A plurality of screen holes are formed in the screening plate, and the screened sodium phosphate particles can pass through the screen holes. A flow divider is installed in the shell, and the flow divider is installed at the bottom of the feeding pipe. In order to make the sodium phosphate entering the shell uniformly distributed on the screening plate, the sodium phosphate is prevented from accumulating on a certain area of the screening plate, and the screening efficiency of the screening plate on the sodium phosphate is improved. A plurality of flow holes are formed in the flow divider, and the sodium phosphate entering the shell flows on the flow divider and falls on the screening plate through the flow holes. A plurality of grinding balls are arranged on the screening plate. Since the screening plate can intercept the sodium phosphate agglomerates and large particles, the sodium phosphate agglomerates and large particles can be ground and broken, so as to pass through the screen holes during screening. The grinding balls can move on the screening plate under the vibration of the shell, and the sodium phosphate agglomerates and large particles can be ground and broken during the movement, so as to improve the screening effect on the sodium phosphate.

A plurality of second magnetic attraction strips are fixedly connected to the side wall of the cylindrical end of the feed pipe. Since the first magnetic attraction strips are not thorough enough in filtering the metal impurities in the sodium phosphate salt, the second magnetic attraction strips are set, so that the sodium phosphate salt needs to pass through the second magnetic attraction strips to enter the shell, so as to filter the metal impurities in the sodium phosphate salt again.
