Commodity: Ammonium nitrate porous prills
1.Production of granular porous ammonium nitrate for industrial use and agricultural granular ammonium nitrate. Products with low moisture content, not easy to cake; high compressive strength, not easy to break; high oil absorption rate. Ammonium nitrate content is more than 99%, the appearance is white granular crystals, no impurities visible to the naked eye.
2. Purpose:
Explosive material: granular ammonium oil explosive is made by mixing porous ammonium nitrate with raw oil. Its speed can reach more than 3 200 m/s. This explosive has strong explosive power, safe and reliable use, low price, cost saving, and can usually reduce the cost by 20%-40%. At present, this kind of explosive has been widely used in mining, construction, railway and highway construction, agricultural and water conservancy construction and national defense and other fields.
Shape:flake, powder, 2-4cm lump and 2-5mm/3-8mm granular
Properties:There are two types,anhydrous aluminium sulphate and aluminium sulphate octadecahydrate. In normal condition , it is AL2(SO4)3 18H2O; AL2(SO4)3 14H2O after efflorescence, can be white powder , glittering flaky or crystalline flakes, odorless, sweet to slight bitter.
Use:Sewage Treatment, treatment of drinking water, Sizing of paper , Cement Additive.

Usage and Dosage:
1. Industrially: ferrous sulphate heptahydrate is mainly used as a precursor to other iron compounds. It is a reducing agent, for the reduction of chromate in cement.
2. Nutritional Supplement: Together with other iron compounds, ferrous sulphate is used to fortify foods and treat iron-deficiency anemia. Constipation is a frequent and uncomfortable side effect associated with the administration of oral supplements. Stool softeners often are prescribed to prevent constipation.
3. Colorant: Ferrous sulphate can also be used to stain concete and some limestones and sandstones a yellowish rust color.
4. Water Treatment: Ferrous sulphate has been applied for the purification of water by flocculation and for phosphate removal in municipal and industrial sewage treatment plants to prevent eutrophication of surface water bodies.
Storage:
Storage Store in cool, dry, well ventilated area, removed from oxidising agents (eg. hypochlorites), acids, metals and foodstuffs. Ensure containers are adequately labelled, protected from physical damage and sealed when not in use. Large storage areas should have appropriate ventilation systems.
Precaution: Flammability Non flammable. No fire or explosion hazard exists.
