[0022] A feed pipe 5 is installed on the top of the frame 1 , a drying cylinder 3 is suspended in the middle of the inner side of the frame 1 , the bottom of the feed pipe 5 is connected to the pretreatment bin 2 , and the bottom of the pretreatment bin 2 is connected to the drying cylinder 3 .

[0023] A screen 12 is fixedly installed in the middle of the pre-treatment chamber 2 , and the bottom surface of the pressing roller 8 is in contact with the top surface of the screen 12 .

[0024] Wollastonite powder is fed into the pretreatment bin 2 through the feed pipe 5, and then the first motor 4 is started. The first motor 4 drives the second connecting shaft 10 to rotate, which is transmitted through the second gear 11 and the first gear 9, and then drives the first connecting shaft 7 to rotate. During the rotation, the pressure roller 8 rotates to crush the large particles of wollastonite powder on the screen 12 until it can pass through the screen 12 and fall into the drying cylinder 3. The uniformity of the particles can effectively improve the drying effect of the wollastonite powder.
