DELMER GT Granulation Tank – Professional Gold, Silver & Copper Water Granulation
The DELMER GT Granulation Tank is an industrial water-granulation system designed to convert molten gold, silver and copper into manageable granules after melting or casting. It combines a stainless-steel process tank, controlled water circulation, temperature monitoring, removable granule collection and provision for external cooling.
Available in 12 KG, 24 KG and 36 KG batch capacities, the range allows jewellery manufacturers, precious-metal refineries, bullion processors and industrial metal users to select the appropriate production capacity without changing the basic process principle.
Choose Your Capacity
| Capacity | Model | Price (INR) | Typical Use |
|---|---|---|---|
| 12 KG | DELMER GT-12 | ₹750,000 | Medium-batch jewellery, refining and alloying operations |
| 24 KG | DELMER GT-24 | ₹1,050,000 | Higher-throughput jewellery and precious-metal processing |
| 36 KG | DELMER GT-36 | ₹1,350,000 | High-capacity production and refinery applications |
Prices shown are base product prices. Final configuration, accessories, cooling system, freight, installation and taxes may be quoted separately where applicable.
Why Use Water Granulation?
Water granulation rapidly quenches a controlled stream of molten metal, producing smaller pieces that are easier to handle, weigh, melt, alloy and feed into subsequent processing. The process is particularly useful where repeatable batch handling and efficient downstream melting are important.
Compatible Metals
- Gold (Au): jewellery alloys, bullion and refinery applications
- Silver (Ag): jewellery, silverware and industrial silver processing
- Copper (Cu): electrical, alloying and industrial metal applications
Core System Features
- SS304 stainless-steel tank: robust welded construction with a smooth, easy-clean internal surface
- Motorized water circulation: continuous tangential circulation promotes controlled water movement around the granulation zone
- Temperature monitoring: digital water-temperature indication for process supervision
- External chiller provision: ready for connection to a water chiller when tighter temperature control or extended production is required
- Removable collection basket: stainless-steel perforated basket simplifies recovery of finished granules
- Splash protection: removable stainless-steel guard improves operator protection during granulation
- Heavy-duty support frame: stable industrial construction for workshop and refinery environments
- Serviceable process layout: accessible water inlet, overflow, drain and circulation connections
- Custom engineering: tank dimensions, circulation arrangement, cooling capacity and collection configuration can be engineered to suit the selected batch capacity

24 KG and 36 KG Systems
The GT-24 and GT-36 are capacity-scaled versions of the same Delmer granulation concept. Their tank volume, circulation arrangement, collection basket and cooling requirements are engineered according to the selected batch capacity and production duty. Exact dimensions, pump selection and chiller sizing are confirmed during technical quotation to match the customer's metal, melt temperature, batch frequency and desired granule characteristics.

Engineering & Customization
Delmer Group can configure the granulation system around the customer's actual production duty. When requesting a quotation, specify metal type, batch weight, melt temperature, batches per hour, desired granule size and available cooling-water conditions. This allows the circulation and cooling arrangement to be selected correctly rather than relying on a generic tank specification.
Delmer Group
Delmer Group develops and supplies precious-metal processing and jewellery-manufacturing equipment, with engineering support for applications involving gold, silver and copper. The granulation tank range is designed for reliable batch processing, practical maintenance and integration with melting and casting workflows.
