Ceramics and its products are made by clay as the main raw material, and a variety of natural mineral after crushing and mixing, molding and calcining.

Fired at high temperatures, the firing process is difficult to control; there will inevitably be a large number of unqualified products. This industrial waste ceramics and ceramic industrial production became solid waste. Due to its high hardness after high-temperature firing, it is not natural digestion, and can’t be reused as ceramic materials, only as industrial waste for landfill disposal, and the processing cost is high, likely to cause environmental pollution. Abandoned ceramics is Mohs hardness below 9.3 and humidity below 6% of non-flammable materials.

The main processing particle level of the waste ceramics is 8 to 5 mm, 5 ~ 3 mm, 1 mm, 1 to 0.5 mm, <0.5 mm, and from 180 mesh to 800 mesh fineness of the fine powder. Of course, higher fineness is also required, we can use the ultra-fine powder grinding equipment or high pressure grinding mill, based on the different fineness, select the appropriate grinding equipments.

The re-use of industrial solid waste is a model of circular economy. For the re-use of waste ceramic, reflecting the guiding ideology of the development of circular economy, ceramic enterprises to reduce waste emissions can even achieve zero emissions, has high environmental and economic benefits. Ultrafine grinding mill, high pressure grinding mill etc. grinding equipments are essential in the waste ceramic reuse.
