And sending unqualified lithium hydroxide particles subjected to hardness detection into the second half cylinder 4 through the feeding mechanism 8 again. And repeating the steps for many times to obtain the large-particle lithium hydroxide with qualified particle size. The output of first half section of thick bamboo 3 and the input of feed mechanism 8 all are provided with the electric butterfly valve of control material business turn over, through being connected the work efficiency of improve equipment with the controller electricity. The rotary joints of the first half cylinder 3, the second half cylinder 4 and the connecting ring 6 and the rotary joints of the stirring mechanism 7 and the second half cylinder 4 are all provided with sealing rings to improve the sealing property. The controller sends the material after mixing into second half section of thick bamboo 4 through pivot 7b through the force pump in, and fixing base 8a makes it can not be along with second half section of thick bamboo 4 is together rotatory for communicating pipe 8b provides fixed stay, makes the structure more stable. The pressure pump plays a role in feeding, and also plays a role in pushing materials in the second half cylinder 4 to the first half cylinder 3, so that the discharging effect of the stirring mechanism 7 is realized. The material can be pumped out by rotating the output end of the first half cylinder 3 and connecting the discharge pump.
