Currently, there are two types of ceramic grinding: grinding with water and grinding without water. Usually, adding grinding fluid during processing can play a role in cooling, lubrication, cleaning, etc., and can also avoid dust flying, but the splashing of grinding fluid will cause pollution to the work scene; when processing small workpieces or small processing volume, adding water is prone to slipping or affecting the performance of the tool, so ceramic grinding will be carried out directly.

When grinding without grinding fluid, a large amount of dust is discharged, and special dust removal equipment is required. Although the emission of dust will be reduced when grinding with grinding fluid, some dust will still overflow. However, it is energy-consuming to set up a separate dust removal device to remove the overflowed dust.

[0050] In the prior art, dust is generated during the grinding process of ceramics. A certain amount of dust will overflow whether grinding fluid is added or not. When grinding without grinding fluid, a large amount of dust is discharged, and special dust removal equipment is required. Although the emission of dust will be reduced when grinding with grinding fluid, some dust will still overflow. However, it is energy-consuming to set up a separate dust removal device to remove the overflowed dust. Now, a dust removal device that can meet two different grinding conditions at the same time is needed, and a dust reduction mode that can switch to adapt to two different grinding conditions for dust reduction work is needed.

[0051] In view of this, the present invention provides a ceramic grinding dust reduction device, such as Figure 1 As shown, the dust reduction device is installed on a ceramic grinder, which includes a dust reduction device and a frame 100, a grinding assembly 200 arranged on the frame 100, and a fixing assembly 300 located at the upper end of the grinding assembly 200 for fixing the workpiece to be ground, and the dust reduction device is installed on the fixing assembly 300; when the grinder is working, the suction cup on the fixing assembly 300 absorbs and fixes the ceramic to be ground, the grinding assembly 200 is composed of a grinding disc and a driving member that drives the grinding disc to rotate, and the fixed ceramic is ground by the rotating grinding disc.
