Greensand is the most Popular form of Molding today. Over the years, the molding process has been refined significantly thanks to the continuous R&D between Foundries and Equipment Manufacturers.
Sand Coolers naturally are an important part of the process if a Foundry needs to run for multiple shifts, But what Exactly is a Moist Sand Cooler, and Why are Foundries choosing these over the standard ones Today?
So, What is a Moist Sand Cooler?
To understand this, we reached out to Mr Akshay Sawant at Akshay Foundry Equipments, Kolhapur who explained the following :
Unlike traditional Sand Coolers that had control on the Temperature of the Sand, Moist Coolers go a step further with advanced PLC’s that retain a consistent 1.4 – 2 % Moisture in the Output Sand.
Moist sand coolers uses controlled airflow and fine water spray in which the sand is gently fluidized. As the water evaporates, it pulls heat out of the sand and cools it evenly while bringing the moisture to the required level.
Therefore, there are no sudden temperature drops or clumps of wet-sand, but instead a uniform, standardized batch.
3 BIG Advantages from Moist Sand Coolers :
.
1. Predictable Moisture Content !
As mentioned by Mr Sawant, Moist Coolers retain a consistent 1.4 – 2 % Moisture in the Output Sand. This method allows for strict quality control of a most important variable.
Unstable Sand can lead to many defects such as scabs, expansion cracks and rough surfaces. However, uniform and consistent sand conditions directly translate into better mould compaction and smoother castings. Foundries that are using moist sand coolers and have often find reduced rejection rates and more repeatable casting quality without extra effort.
After all, Quality Casting are really just a by-product of good variable control.
2. Saving on Sand Additives (Bentonite)
Since the Sand retains it’s moisture as compared to completely drying up, this enables the Bentonite in the Sand to stay activated prompting lower sand additives in the cycle, adding to profits directly. Profits are important for a Foundry.
3. Cleaner Environment
This modern design of Moist Sand Coolers also reduces dusting and improves workplace hygiene. They also require low maintenance as a result.
Why Akshay Foundry Equipment’s Moist Sand Coolers are a TOP Choice.
Foundries in India have always trusted Akshay Foundry Equipment for Decades with entire Greensand Sand Plants, Mixers, Bucket Elevators, Knowckout Equipment and recently even High Pressure Moulding Lines through their collaboration with Zoomzu an established Chinese brand in HPML.
These Moist Sand Coolers are designed with that same deep understanding of foundry operations. Thus, we recommend you can Trust them blindly.
