[0002] Calcium silicate boards can be used to make thermal insulation materials, wear-resistant materials, refractory materials, etc. In the construction field, calcium silicate boards can be used for thermal insulation layers, firewalls, sound insulation walls, etc. In the electronics field, calcium silicate boards can be used to make supporting materials and insulating materials for electronic components, etc. In the mechanical field, calcium silicate boards can be used to make wear-resistant parts, corrosion-resistant parts, etc. During the production of calcium silicate boards, since the end faces of the newly produced calcium silicate boards are relatively rough, a grinder is needed to grind the end faces of the calcium silicate boards. When grinding calcium carbonate boards, a large amount of dust will be generated on site, which will have an adverse effect on the staff.

[0003] The utility model patent with the authorization announcement number CN214264961U discloses an environmentally friendly grinder for producing calcium silicate boards.

[0037] Working principle of this utility model:

[0038] S1. First, lay the calcium carbonate board to be processed on the rotating roller 2, and fit the side to be polished to the polishing disc of the polisher 17;

[0039] S2, start the exhaust fan 13, the exhaust fan 13 evacuates the space of the lower cavity in the housing 1, after a certain period of time, the plug 9 moves downward under the action of the external air pressure, the upper end of the plug 9 is separated from the vent 6, and the lower end of the plug 9 drives the slide bar 8 to move downward, compressing the spring 10 in the sleeve 7;

[0040] S3, start the grinder 17, the grinder 17 grinds the end surface of the calcium carbonate board, and the staff assists in pushing the calcium carbonate board so that the end surface of the calcium carbonate board is polished;

[0041] S4, the dust generated by grinding is guided by the guide cover 4 and then enters the upper cavity through the dust inlet 3, and then is sucked into the lower cavity through the vent 6 by the exhaust fan 13 and discharged, and finally is uniformly intercepted and collected by the non-woven fabric cover 14, so as to achieve a dust-free state of the on-site environment. When the exhaust fan 13 is turned off, the plug 9 is reset under the rebound force of the spring 10, and the vent 6 is re-blocked, and the upper cavity and the lower cavity are not connected, so that the dust will not overflow;

[0042] S5. If the end face of the calcium carbonate board needs to be chamfered, the threaded rod 19 only needs to be rotated by the knob 21. The threaded rod 19 will produce relative displacement through the threaded movement between the threaded rod 19 and the internal threaded sleeve 18, so that the motor seat 16 will produce a change in the elevation angle, and further the angle of the grinder 17 will be offset. In this way, the grinder 17 can not only grind the end face of the calcium carbonate board, but also perform chamfering, thereby increasing the overall functionality.
