1. Product Description
The Industrial Rotary Dryer for Precious Metal Concentrate is professional drying equipment developed for continuous dehydration of precious metal concentrates such as gold, silver and platinum group concentrates in mineral processing plants. Precious metal concentrate has ultra-fine particle size, slight viscosity and certain abrasiveness. Uneven moisture will negatively affect subsequent leaching, smelting and refining processes, and may cause material loss. This rotary dryer adopts thickened wear-resistant cylinder shell, precision anti-caking lifting plates, stable and controllable heating system and high-precision intelligent monitoring module. It can steadily remove surface and internal moisture of wet precious metal concentrate, maintain stable material moisture, and adapt to long-term continuous heavy-load operation. It is essential supporting equipment for precious metal beneficiation and smelting projects.
2. Working Principle
This rotary dryer for precious metal concentrate adopts gradient countercurrent circulating heat exchange and continuous low-loss dehydration principle. Wet precious metal concentrate is quantitatively and continuously conveyed into the rotary drum through the feeding system. The anti-caking and wear-resistant lifting plates repeatedly lift, overturn and scatter ultra-fine concentrate materials to avoid agglomeration and wall adhesion, forming a uniform material curtain for sufficient contact between precious metal concentrate particles and hot air. Stable hot air flows countercurrently inside the drum for progressive heat exchange to gradually evaporate moisture. The PLC intelligent system monitors drum temperature, air volume and outlet concentrate moisture in real time, and automatically adjusts feeding speed and heat supply to keep stable drying quality and minimize fine material loss. Exhaust gas and ultra-fine precious metal dust are collected and purified by the sealed high-efficiency dust removal system to meet environmental emission standards and recover valuable metal powder. Qualified dried precious metal concentrate is continuously discharged for subsequent leaching and smelting procedures.
3. Core Features
Thickened wear-resistant cylinder and precision lifting plates, adapting to ultra-fine precious metal concentrate and reducing material wear loss.
Special anti-caking structure, effectively solving agglomeration of high-moisture fine precious metal concentrate.
Precise temperature and air volume control, avoiding overheating and reducing loss of valuable fine powder.
Optimized heat exchange layout, high drying efficiency and remarkable energy-saving performance.
High-precision intelligent real-time monitoring and automatic parameter adjustment, reducing manual operation.
Equipped with high-efficiency sealed dust collection system, low dust emission and recycling of precious metal dust.
