Attapulgite clay refers to a clay mineral with attapulgite as the main component. Attapulgite clay has cation exchangeability, and after activation treatment, the amount of exchangeable cation is significantly increased. The adsorption decolorization performance is related to the content of attapulgite, the higher the content, the stronger the decolorization power.
The limestone is fed into the bucket elevator and subsequently transported to the raw material warehouse for grinding.
After grinding, the finished products are gathered by powder concentrator, and then conveyed to a screw conveyor.
The finished products are transported to the storage warehouse, while the excess gas is filtered by the dust collector.
The whole system is equipped with three pulse dust collectors to guarantee that the whole system is free of dust leakage.
The system is outfitted with an intelligent PLC control cabinet and an upper computer.
The system is equipped with an intelligent PLC control cabinet and an upper computer.
1. Animal food binder: use attapulgite to connect various nutrition together, it need 120mesh, 150mesh, 200mesh, and water content should be -15%;
2. Fertilizer binder: it needs 100mesh, 120mesh, 150mesh, water content should be -15%;
3. Foundry sand binder: it needs 100mesh, 150mesh, 200mesh, water content should be -15%;
4. Cat Litter: it needs 10-30mesh, 20-40mesh or 200mesh with followed pelleting procedure, water content should be -15%;
The processed attapulgite clay products are ideal adsorbents, food processing aids and food additives, and can replace activated carbon. It can not only decolorize, but also deodorize and deodorize, remove heavy metal ions and carcinogens, and has a certain selectivity, which provides convenience for production. It can be used as a refrigerator deodorant, sewage treatment agent, household water purifier, Oil refining decolorizing agent, the effect is very obvious.
