They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0019] The utility model is a steam-powder machine with a novel lining plate structure. The utility model improves the steam-powder machine, and the improvement is based on the existing steam-powder machine, mainly improving the wear-resistant lining plate of the steam-powder machine.

[0020] like Figure 2As shown, the steam pulverizer mainly comprises a circular grinding chamber 1 and a cover plate 2 arranged on the upper end surface of the grinding chamber 1. The grinding chamber 1 is sealed by the cover plate 2, so that the grinding can be performed in the grinding chamber 1 to grind the material into fine powder. A feed pipe 3 and a discharge port 4 are arranged on the cover plate 2, and the material to be ground is transported into the grinding chamber 1 through the feed pipe 3. After the processing is completed, the ground powder is discharged from the discharge port 4.

Both the main wear-resistant lining plate 5 and the side wear-resistant lining plate 6 are detachable installation structures, and can be disassembled and replaced after being worn out for a long time.

[0022] Specifically, the main wear-resistant lining plate 5 is set as a fan-shaped structure. The main wear-resistant lining plate 5 is a press-fit installation structure. Specifically, the outer end of the main wear-resistant lining plate 5 is pressed and fixed by the side wear-resistant lining plate 6, and the inner end is pressed and fixed by the wear-resistant pressure plate 8. A plurality of main wear-resistant liners 5 of fan-shaped structure are arranged around the center, and finally closed to form an annular structure. The main wear-resistant liners 5 are mutually limited in position on the plane and cannot be moved at will. In the radial direction, they are limited and fixed by the side wear-resistant liners 6 and the wear-resistant pressure plate 8.

[0023] like Figure 3 As shown, in a specific implementation, there is a bite-type clamping structure between the main wear-resistant liner 5 and the wear-resistant pressure plate 8. Specifically, a step groove is provided on the upper side of the inner end of the main wear-resistant liner 5, and at the same time, a step groove is also provided on the lower side of the outer end of the wear-resistant pressure plate 8. The step groove of the wear-resistant pressure plate 8 is adapted and pressed to the step groove of the main wear-resistant liner 5. Further, the wear-resistant pressure plate 8 is fixed to the bottom surface of the grinding chamber by bolts.
