Castofoam Stainless Steel Lost Foam Sand Cooler, for Industrial, Certification : ISI Certified

Listing ID #6654388

For catering the variegated demands of our respected clients, we are highly engrossed in providing a wide range of Vertical Sand Cooler. 
Designed for dedusting and cooling molding sand (bulk materials with a fraction of 0.08 mm to 0.8 mm with a density of 1.2-1.8 tons per cubic meter) to the operating temperature. Works on the principle of "fluidized bed". Water heat exchangers are installed in the "boiling" zone of the sand, they are used in the summer. The high-pressure fan creates a fluidized bed of sand. The air passing through the hot sand takes heat and dust fraction, then it enters the cyclone-type dust collector through the aspiration branch. After the cyclone, another fan is installed to equalize the air pressure in the cooler.
The cooler is supplied with an aspiration system. A temperature sensor is installed at the outlet cooler, which allows you to control the temperature of the sand. The temperature of the sand at the outlet of the cooler depends on the cooling time and the temperature of the air supplied to the cooler. The sand cooling time can be adjusted according to the time of operation of the air damper for unloading. 
Part of the equipment:

• Cooler body
• High pressure fan
• Air distribution manifold
• Cyclone
• The fan is centrifugal
• Air ducts

The technological unit is designed for cooling molding sand. The sand cooler uses the "fluidized bed" principle, i.e. Atmospheric air passes through the sand layer at high speed, causing it to boil. The air that cools the sand carries the dust fraction into the cyclone, and, having passed it, purified, is released into the atmosphere. A water heat exchanger is installed in the sand boiling zone, which speeds up the cooling process. The time spent by the sand in the cooler can be adjusted by the operator from the control panel by closing the pneumatic valve when unloading into the elevator.
In our LFC equipment, we use an air sand cooler with a built-in water heat exchanger and, depending on the climatic zone of use of the equipment and its performance, we supplement the sand hopper with another water heat exchanger. This scheme allows you to guaranteed cool the foundry sand to its operating temperature. 
The use of a sand cooler designed by Castofoam India Pvt. Ltd is possible not only in the LFC process, but also in any technological process where quartz sand with similar temperature parameters is used (in the production of building mixtures, glass production, etc.)
