High Efficiency Rotary Drum Dryer with 93% Thermal Efficiency and 30% Waste Heat Recovery for Gold Ore Processing

Product Description

The high efficiency rotary drum dryer is an optimized energy-saving industrial drying equipment designed to boost drying efficiency and cut energy consumption. It adopts a restructured internal heat exchange system and streamlined air duct design, with thermal efficiency far higher than that of conventional models. It is widely used in large-capacity drying scenarios across new energy, chemical, food, environmental protection and other industries, effectively lowering the overall energy cost of production lines.

Working Principle

The specially optimized drum is driven by a low-power high-efficiency transmission system to run stably. The built-in combined heat-conducting lifting plates fully scatter the materials into a uniform thin material curtain, maximizing the contact area between materials and hot air. The multi-stage gradient temperature control zones precisely match the moisture evaporation rules of materials, making full use of the heat energy of hot air to efficiently take away the moisture. The waste heat of the exhausted tail gas is recycled and reused through the preheating system, and the dried materials are discharged stably, realizing the high-efficiency and low-energy-consumption continuous drying process.

Key Features

• ‌Ultra-high thermal efficiency‌: The optimized heat exchange structure raises the thermal efficiency to over 93%, which is 20%~30% higher than that of ordinary rotary drum dryers, and the unit energy consumption is greatly reduced.
• ‌Fast and uniform drying‌: The full-contact heat transfer design shortens the material drying time, and the moisture uniformity of the finished materials is controlled within ±0.3%.
• ‌Significant energy saving effect‌: The built-in tail gas waste heat recovery system can recycle more than 30% of the waste heat, effectively reducing the operating cost of long-term production.
• ‌Wide adaptability‌: It supports customized configurations such as stainless steel anti-corrosion, high output, low maintenance, etc., and the processing capacity covers 5kg/h to 2000t/d, meeting the high-efficiency drying demands of different industries.
