Fluorite demineralization process

The invention discloses a fluorite decalcification beneficiation process, which is composed of one rough selection and multiple selection operations, and is roughly selected by using oleic acid or its substitute as a collector , and sulfuric acid and acidic water glass are used. The mixture is used as an inhibitor of calcium-containing minerals, and the ratio of sulfuric acid to acidic water glass is 1:0.5 to 1:2, and the combined amount is 0.5 to 1.5 KG/T of ore. The fluorite decalcifying ore dressing process provided by the invention has the advantages of high calcium removal efficiency, simple process and low cost, and a special grade fluorite concentrate with low calcium carbonate content can be selected from the high calcium type fluorite ore.

PC Hollow Sheet Line

PC Hollow Sheet Line is applicable to produce PC,PP,PE hollow profile board. The products is used widely for building, decorating, advertisement laying, road noise isolation ,roofing and packing. PP hollow profile board can instead of carton which have feature like light weight, high strengthen, moisture-proof, antisepsis.

1. The vacuum calibrator featured with wear-resistance, dirty free and the lifting, falling and leveling for the forming plates is much easier to be controlled.

2. High speed screw, low energy consumption with high rotation speed to match gear pump and stable pressure; output capacity is 25% higher than other brand extrusion lines. because of special design of forming plates.

3. Special designed cooling system for all section of forming plates, and unique designed vacuum system for each section of forming plate.

4. Special designed temperature control oven with cross heat shrink forming, which is much easier to be controlled than other brand extrusion lines.

5. The softness of pull rolls could be customized on request to extend its stretch.

6. The air capacity of hollow sheet and low pressure could be adjusted and controlled slightly, which is easily to be controlled than any other brand extrusion lines.

7. Unique T-Die made by JC Times is specially designed for PP hollow sheet. The thickness of hollow sheet could be from 2mm to 10 mm with twin-wall. The ribbed between walls could be rectangular and diagonal shape.

8. Anti-UV co-extrusion layer could be one sided or two sided, outer surfaces could be sandy or glossy according to configuration requirement.High percentage of recycled flakes could be mixed with the virgin materials.
