Product Description

Rotary dryer is a machine used in the drying process. It is a special kiln that usually works in conjunction with a combustion system. Heat passes through its internal cylinder to dehydrate the material inside. Material can be added and extracted during the drying process, enabling continuous operation. Material enters the drum dryer from one side and exits from the other. Hot air generated by the burner passes through the dryer to raise the internal temperature.

Product Advantages

1. High-efficiency drying capability:
The rotary dryer utilises a rotating cylinder to provide a larger contact area between the material and the hot airflow, accelerating heat exchange efficiency and thereby achieving a higher drying rate. Its special design is suitable for continuous production of large batches of material, reducing drying time and greatly improving production efficiency.

2. Wide applicability:
The rotary dryer can process materials of various forms, including powdery, granular, and paste-like, effectively drying materials of different particle sizes and moisture contents. Whether it is ore, coal, slurry, distillers' grains, clay, sand, or agricultural waste such as wood chips and sawdust, the rotary dryer can achieve efficient drying.

3. Equipment operational stability:
The rotary dryer employs a stable rotating system combined with efficient heating devices. Even under prolonged, high-load operating conditions, it maintains high-efficiency drying performance, ensuring stable equipment operation while reducing failure rates and maintenance costs. Its unique structure minimises material adhesion and blockages during the drying process, further enhancing production continuity.

4. Automated control and user-friendly operation:
Modern rotary dryers are typically equipped with automated control systems that allow precise adjustment of drying temperature, time, and material flow rate. Through these automated parameter settings, operators can easily monitor and adjust equipment operating parameters, improving the precision and stability of the drying process.

Product Application

1. Rice husk drying:
Rice husks are a by-product of rice processing and typically have high moisture content. Rotary dryers can quickly remove moisture from rice husks through efficient heat sources and rotating structures. Dried rice husks can be used as biomass fuel, soil conditioners for horticulture and agriculture, or as raw materials for high-value products.

2. Clay and Mineral Powder Drying:
Clay and mineral powder require specific moisture content levels for various industrial applications. Rotary dryers can control temperature and drying time to ensure clay and mineral powder achieve optimal drying results, minimising material loss and enhancing the quality of subsequent processing steps. By precisely controlling the drying process, over-drying or under-drying is avoided, ensuring uniformity and stability of the material.

3.Mining and Metallurgy Industry:
Rotary dryers are widely used in the mining and metallurgy industry, primarily for drying materials such as ore, coal, bauxite, and silica sand. In metallurgical production processes, raw materials like ore and coal often require high-temperature drying to enhance their combustion efficiency and chemical reaction rates. Rotary dryers effectively remove moisture from ore and coal, optimising their physical properties and providing more efficient raw materials for subsequent smelting processes.

4.Fertiliser Industry:
In fertiliser production, rotary dryers are used to dry nitrogen fertilisers, phosphorus fertilisers, potassium fertilisers, and other fertiliser raw materials. These fertilisers typically contain high moisture content during production and must undergo drying treatment to meet standard storage and transportation requirements. Rotary dryers feature high processing capacity and fast drying speeds, efficiently removing moisture from fertilisers while maintaining the stability of their chemical composition, ensuring product quality.
