Can solid waste be ground?

Solid waste refers to the solid or semi-solid waste generated by humans in the process of production and daily life. If left untreated for a long time, it will occupy land resources and pollute the environment. Grinding equipment can be used to treat such national waste and avoid the long-term impact of waste accumulation on the surrounding ecological environment and people's physical and mental health. So, what fields can grinding equipment be applied in solid waste treatment. For example, red mud, fly ash, steel slag, etc.

Firstly, the grinding equipment is applied to red mud. It is a polluting waste residue generated during the extraction of aluminum oxide in the aluminum industry. If left untreated and discharged arbitrarily, it will cause serious pollution to the surrounding environment. The main pollutants in red mud are alkali, oxides, sodium, aluminum, etc. The chemical components in red mud stored for a long time can seep into the land and groundwater, causing land alkalization and water source deterioration. When the country is struggling with red mud pollution, red mud contains CaCO3, Al2O3, and a large amount of silicates, especially sintered red mud which contains a large amount of β- Dicalcium silicate can be used to produce cement. By using a grinding machine as the main equipment, a complete cement production line can be established, which not only alleviates environmental pollution problems but also brings a certain amount of cement raw materials to building materials.

Fly ash, steel slag, and other solid waste in industrial production can also be used as cement and concrete raw materials after crushing and grinding. In addition to Raymond mill, ultra-fine powder mill, ultra-fine vertical mill, and vertical powder mill can all be used as grinding equipment.

Grinding equipment not only has important applications in the above-mentioned fields, but also plays an important role in industrial slag, coal grinding stone, waste products, and damaged materials. Grinding equipment has become an essential equipment in the industrial field, and the demand for ore grinding machines is increasing in various fields such as power plants, water sludge, coal, and non-metallic mines.
