Rock Flour
Quarz sand .Powder
Quartz sand is a kind of chemically stable silicate mineral ,which is hard and abrasion-proof.Fundamental ingredients: SiO2≥99-99.5%,Fe2O3≤0.02-0.015%.More than 7 rigidity, relative density is 2.65, proof to acids and bases and the melting point is 1750ºC. It is the main materials to make glass and ceramic, and it can also be used in chemical industry, grinders and grinding materials and fire-proof stuff.
Color Sand
Coming from such raw materials as granite and marble,color sand is one of the major products in Taihang mountain areas.Jinli carefully chooses and demolishes it from such minerals as Zhongguo Hei, Zhongguo H-ong,Taihang Hong, Juhong ,SENLINLV,Wan nianqing and Juhuahuang, etc. Color sand is mainly used in constru-ctive materi- als,man-maderivers and spares.
Feldspar Power Chemical formula : K(ALSIO3O8)
K-feldspar is a silicon-oxygen tetrahedron frame structure consisting of potassium and sodium, calcium, barium silicate minerals.
Feldspar is a aluminium silicate mineral composed of kalium,natrium,calcium and barium. Its major ingredients include 65% of SiO2 70% AL2O3 16% K2O 9.55% Na2O 2.4% CaO 0.5% of CaO,with a 2.2-2.56g/cm3 of density,and a Mohs rigidity Of 6-6.5. Feldspar can stand high pressure and is proof to acids and also is main raw material to produce glass and ceramic .In addition, it can be used in chemical industry, grinding materials, electrode accessories, fireproof substance, paper making and agricultural fertilizer, etc.
Washed and Dried Sand
Taken from the rivers , it is washed with water, dried and graded into various sizes. It is mainly used in building materials.
