The invention discloses a
bauxite lightweight through-hole ceramsite. The key point of the technical scheme is that the
bauxite lightweight through-hole ceramsite consists of
bauxite, attapulgite, a powdered bauxite foamer, activated clay waste residues, floating beads, light
magnesium oxide, expanded
perlite, expanded
vermiculite and
ferrous sulfate. The ingredients of the bauxite lightweight through-hole ceramsite are stirred and mixed, extruded and pelletized, dried, roasted, warm-kept, sieved and then packaged in a sealing manner. The bauxite lightweight through-hole ceramsite has the characteristics of large specific surface area, small stacking density, high water absorption, superior air permeability, attractive
appearance modeling, no foreign smell, no harmful germ, light weight, high strength, and micropore and
macropore integration. When the bauxite lightweight through-hole ceramsite is used for cultivating or planting various seedlings, flowers and plants and vegetables, the
plant roots can absorb nutritional ingredients of water or liquid fertilizers from the bauxite lightweight through-hole ceramsite, so that good growth and development,
high survival rate and longer service life of the plants are ensured, and the bauxite lightweight through-hole ceramsite is suitable for preparing soilless culture substrates and
nutrient soil.
