In industries such as mining, construction, and glass manufacturing, river sand dryers (also known as sand dryers, yellow sand dryers, or quartz sand dryers) are indispensable key equipment. They can efficiently process sand, mineral sand, and other granular materials with high moisture content, ensuring that the dried product meets industrial standards (moisture content below 0.5%~1%).
As a professional mining equipment manufacturer, we deeply understand the impact of the drying process on production efficiency. River sand dryers, with their advantages of large processing capacity, low energy consumption, and stable operation, have become the first choice for many companies. Whether it's viscous, pasty materials or wet sand with a moisture content as high as 8.4%, our rotary dryers can process them efficiently, with an hourly output of over 1 ton and operating costs as low as less than $5 per ton.
Working Principle of River Sand Dryers
Our rotary dryers use high-temperature hot air drying technology. The drum has specially designed lifting plates welded inside. As the drum rotates, these lifting plates continuously tumble the sand, ensuring it comes into full contact with the hot air, causing the moisture to evaporate rapidly.
Key steps in the drying process:
1. Feeding and heating: Wet sand enters the drum and mixes with high-temperature hot air.
2. Tumbling drying: Lifting plates tumble the sand up and down to ensure even heating.
3. Steam discharge: A high-pressure blower extracts the evaporated water vapor and sends it to a cyclone dust collector.
4. Dust collection: The cyclone dust collector separates dust, and the purified gas is discharged through a chimney.
5. Finished product discharge: The moisture content of the dried sand is reduced to 0.5%~1%, meeting industrial standards.
Core advantages of the river sand dryer:
✔ High processing capacity: Even the smallest model can process more than 1 ton of material per hour.
✔ Low energy consumption: Optimized hot air circulation system, drying cost per ton is less than $5.
✔ High adaptability: Can dry river sand, quartz sand, mineral sand, high-moisture viscous materials, etc.
✔ Stable and durable: Made of wear-resistant steel, suitable for long-term high-intensity operation.
✔ Environmentally Compliant: Equipped with a cyclone dust removal system to reduce dust emissions and meet environmental protection requirements.
