Precious metal granulation equipment
Taeantech supplies the TA-GR series for workshops that need consistent granules from gold, silver, copper, and alloy melts. The equipment is built for small and medium precious metal operations that compare granulating machine machine suppliers by capacity, control accuracy, granule size range, and export communication.
For buyers also evaluating melting and casting equipment suppliers, this page summarizes the practical model differences, installation checks, and quotation details needed before selecting GR1, GR4, or GR10.
Machine review
The TA-GR granulating machine melts precious metal inside a controlled chamber and forms small granules through a water-cooling process. The product page lists PLC and HMI operation, PID temperature control, inert gas protection, and a compact production cycle for workshops that need repeatable granule preparation before casting, refining, or alloy handling.

GR1, GR4, and GR10 give buyers a clear path from sample-scale work to 10 kg batch processing without changing the basic production method.
The listed argon or nitrogen protection, PID control, and PLC operation support stable process control for precious metal workshops.
Taeantech can review material type, local voltage, target capacity, and installation conditions so buyers receive a practical equipment recommendation.

Procurement FAQ
The TA-GR series is presented for gold, silver, copper, and related alloy granulation. For alloys with unusual melting behavior, buyers should confirm the working temperature, crucible selection, shielding gas plan, and required granule size before ordering.
Selection should begin with batch weight and daily output planning. GR1 suits small sample or workshop batches, GR4 suits medium jewelry and refining work, and GR10 supports larger 10 kg batches where stable cooling, power supply, and operator workflow are already prepared.
Shielding gas helps reduce oxidation during melting and granule formation. Buyers should prepare a suitable gas source, regulator, and operating procedure so the melt chamber receives steady protection during the heating and pouring cycle.
Buyers should check voltage, power capacity, cooling water availability, ventilation, shielding gas supply, operator access, and floor space. The larger models have higher power and weight requirements, so site preparation should be confirmed before shipment planning.
The product page lists a granule size range of 0.8 to 4.0 mm. Final particle behavior depends on metal type, melt temperature, water flow, nozzle condition, and operating settings, so sample evaluation is useful for critical downstream processes.
A useful inquiry includes target metal, alloy range, batch weight, expected daily output, required granule size, local voltage, installation country, shielding gas plan, and whether the buyer also needs related melting or casting equipment.
