Double Belt Coolers

1. Double belt coolers working principle


Molten material melt by reactors is fed into double belt cooler’s head through the material pump at a constant speed and pressure, overflows continuously and evenly onto surface between two steel belts and forms premium sheet by melt solidification. Finally the sheet will be crushed as the flakes by crusher and entered to metering and packing process. Built-in interlock switch and emergency brake system ensure operation safety. Cooling water won’t contact with material in the cooler system. The uncontaminated cooling water can be recycled or discharged without pollution to the environment.

  • Low cost consumption


4. Why Jingtao


There are many double belt coolers in the market, why Jingtao can win so many high end customers since establishment? Jingtao double belt coolers are positioned in high quality level and correspondingly match customers who need high quality flakes. Some of customers who have bought cheap equipment in the market and have many complaints after using then consult back to Jingtao to purchase it to keep their production line stable and high productivity.

So what special advantages does Jingtao have?

  • Jingtao purchase qualified raw material and don’t compromise on raw material.

  • To make the equipment stable, safe and durable, Jingtao creates special elaborate technique with accurate design, which is different from competitors and hard to imitate by them.

 

  • Cooling zone-Tension end

Jingtao tension end adopt disc spring, offering the suitable stretch automatically to ensure the long lifetime of steel belt and correct the deviation of the steel belt.



Others adapt spiral spring or even without any spring, no enough tension to the steel belt, cause to steel belt break, affecting the lifetime of steel belt.


  • Cooling zone -Support assembly

Jingtao support assembly :

Upper belt support assembly as herringbone shape using high wear-resistant electric board to support the steel belt steadily

and scrape down the water quickly by rapid heat exchange.

Lower belt

Roller with 4 points of support instead of a whole. The built-in maintenance-free bearing ensures a longer lifetime.

 

    


Others upper belt support adopt normal phenolic or epoxy board, it can soften in the water and can’t scrape the water well.

 

Lower belt support makes the roller as a whole without separate section, causing the distortion of steel belt and finally affect the lifetime of steel belt.


  • Cooling zone-spray assembly

Jingtao: Water pipe with semicircular stainless

sprayed in a solid cone on the back of the steel belt, taking away the heat from the belt.

Design(1.5m steel belt widith): every 2.5m with 4 rows water pipe and each row is 7 pcs nozzle, 5m cooling section 56pcs,4 rows large nozzle accurate layout and angle sprayed;Large diameter nozzle –significant cooling effect;Quick release design –easy cleaning and replacement.

 

 


Others makes the solid cone water form a cross collision before they are sprayed on the steel belt, causing the water falling in the middle, so the cooling and heat exchange efficiency is low.



            

  • Cooling zone-water collection and drainage

Jingtao water collection and drainage: all parts contacting with water adopt 304 stainless steel, with maintenance free, waterproof and rustproof.  Jingtao drainage design detailly to avoid water leakage and make water drain smoothly. All parts contact with water, we use 304 stainless steel. We make water collecting plate with slope design to ensure water to drain tank with high pressure, which can quickly discharge the water.




Others: To save cost, not all parts adopt 304 stainless steel, causing to leakage of water and no rust proof. And the water is blocked inside and can't drain very quickly.
