Our mining-industry requirements Reference Manual provides general industrial requirements of lead ore bed is: cut-off grade sulphide ore is 0.3-0.5%, the lowest industrial grade of 0.7 to 1.0%; cut-off grade oxide ores 0.5-1% , the lowest industrial grade 1.5-2%; cut-off grade ore mixing 0.5-0.7%, the lowest industrial grade 1-1.5%; zinc deposit general industrial requirements are: cut-off grade sulphide ore 0.5-1% minimum The industrial grade is 1-2%; the cut-off grade of oxidized ore is 1.5-2%, the lowest industrial grade is 3-6%; the cut-off grade of mixed ore is 0.8-1.5%, and the lowest industrial grade is 2-3%. Round Open Water Cooling Tower The whole structure is solid and light;the body and water pond is manufactured with reinforced glass fibre (FRP glass fiber reinforced plastics),never being corrosive. The surface finish is added with ultraviolet inhibitor,which can resist sunshine attack and damage.
Apply special design PVC water block curtain (water-stop) to prevents plashing) remarkably; pressure drop loss is slight and splashing loss i under 0.001%.
Apply cellular vacuum molding heat dissipation material, stagger arrangement surface has grooves and the heat exchange effect is especially good.

All steel and iron material is processed through galvanizing by dipping,Ocorrosion resisting and durable.
Special designed axial-flow type air blower applies belt reduction gear,reducing low noise and sufficient wind; tailor-made water-drop noise
reduction carpet to eliminate water sound.
Water pond applies slant design, easy to wash, containing less water; the operating weight is lower, but the water tank is very big, so it won't absorb air.
The cooling tower support is light and solid, convenient to assembly no matter there is suspension iron rack or not.
