WUXI WONDERY INDUSTRY EQUIPMENT CO., LTD – Innovating Zinc Powder Recycling Process with Advanced Gas / Oil Heating Rotary Melting Furnace Technology

Recently, we had received an inquiry from a customer who had a failed experience of melting pure zinc powder. After seen the videos sent by the customer, we found out that the furnace they bought is a gas fired melting furnace without rotation function and the flame directly contacts the zinc powder which causes a significant amount of melting loss.

As a leading melting furnace manufacturer, we have achieved a significant breakthrough in zinc powder production by optimizing the rotary furnace process. By adopting a "non-direct flame contact" heating method, the company successfully reduced zinc powder melting loss, significantly improving production efficiency and economic performance.

*"Direct flame contact is one of the primary causes of zinc burn-off," explained the company’s technical director.” Our new process enhances recovery rates from 85% to over 92% through precise temperature control, rotary function and indirect heating, while also reducing impurities."

Key Points in Designing a Zinc Powder Melting furnace:

1. Rotary function for improving melting efficiency;
2. Indirect heating method via a furnace muffle tank (F08 20mm) for reducing melting loss;
3. Charging zinc ingots material first and add zinc powder once the ingots are melted into liquids. Every time keep a certain amount of zinc liquid in the muffle tank. This would improve the overall melting efficiency.

Industry Impact & Sustainability Benefits

Zinc powder is widely used in **batteries, anti-corrosion coatings, and alloy manufacturing**, with growing market demand. Reducing burn-off not only improves resource efficiency but also aligns with China’s green manufacturing policies. This advancement is expected to drive the industry toward **higher efficiency and lower environmental impact.
