Materials We DO NOT Process
If you are looking to dry the following materials, our equipment is NOT suitable for your needs.
- 🍎 Food & Beverage: Fruits, vegetables, grains, coffee beans, tea leaves, or meat.
- 💊 Pharmaceuticals: Medical herbs, pills, or delicate chemical powders.
- 🌾 Light Agriculture: Wood chips (for small scale), delicate biomass, or high-end refined chemical fertilizers.
- 📦 Heat-Sensitive Materials: Plastics, resins, or materials that melt easily under high direct heat.
For ores & minerals
Heavy-Duty Drying for Abrasive and High-Density Materials
Ores and minerals are heavy, abrasive, and often require high temperatures. Our heavy-duty rotary dryers are built with wear-resistant steel to ensure continuous, low-maintenance operation in harsh mining environments.
Materials we handle:
- Metal Ores & Concentrates: Iron Ore, Mineral Concentrate, Tailings, Metal Powder.
- Non-metallic Minerals: Quartz Sand, Silica Sand, Bentonite, Fluorite Powder, Kaolin.
- Slag & By-products: Mineral Slag, Granulated Blast Furnace Slag (GBFS), Water Slag.
The challenge & our solution:
- The Industry Challenge: Heavy, abrasive materials quickly wear down standard equipment inner walls, leading to high maintenance costs and frequent downtime.
- The Hengxing Solution: We utilize heavy-duty, boiler-grade steel plates and specially reinforced lifting flights. This anti-wear design ensures maximum throughput while extending the equipment’s service life by up to 30% compared to standard models.
Recommended equipment:
For sand & construction
High-Efficiency Drying with Maximum Fuel Savings
Whether you are producing dry mortar, cement, or glass, strict moisture control is critical. Our sand drying systems are designed for high evaporation capacity, delivering final moisture contents consistently below 1%.
Materials we handle:
- Sand Types: River Sand, Yellow Sand, Washed Sand, Frac Sand.
- Construction Raw Materials: Clay, Soil, Cement Raw Materials, Dry Mortar.
The challenge & our solution:
- The Industry Challenge: High-volume sand drying demands massive throughput. However, sand has excellent flowability, meaning fuel costs can easily ruin your profit margins if the drying process is inefficient.
- The Hengxing Solution: We strongly recommend our Triple Pass configuration. By utilizing an internal three-cylinder heat exchange design and residual heat recovery, this system increases thermal efficiency by over 40%, drastically reducing your coal, gas, or electricity consumption.
Recommended equipment:
For coal & energy fuels
Safe, Low-Temperature Drying to Preserve Calorific Value
Drying combustible materials like coal and slime requires precision and absolute safety. We utilize low-temperature, large-volume air sweeping technology to safely dry energy fuels without altering their calorific value.
Materials we handle:
- Coal & Tailings: Coal Slime, Lignite (Brown Coal), Coal Gangue.
- Coal Chemical Products: Coke, Semi-Coke, Carbon.
- Ash By-products: Fly Ash.
The challenge & our solution:
- The Industry Challenge:Combustible materials pose explosion risks. Furthermore, high-moisture coal slimes easily stick together into large lumps, resulting in a “dry outside, wet inside” outcome.
- The Hengxing Solution: Safety is guaranteed with our strict temperature monitoring systems and explosion-proof valves. For sticky slimes, we install internal breaking shafts (breakers) that continuously crush and toss the lumps during rotation, ensuring perfectly uniform drying.
Recommended equipment:
Sludge, waste & manure
Anti-Sticking Solutions for High-Moisture Waste
Transform sticky, high-moisture waste into valuable resources. Our specialized dryers handle clumping materials effectively, turning sludge and manure into manageable, dry by-products for organic fertilizer or safe disposal.
Materials we handle:
- Industrial Waste: Industrial Sludge, FGD Gypsum, Furnace Slag.
- Organic Fertilizer Materials: Poultry / Chicken Manure, Cow Dung, Pig Manure.
The challenge & our solution:
- The Industry Challenge:Extremely viscous and high-moisture materials stick to the dryer walls (wall-sticking), reducing heat transfer efficiency and often causing severe odor emissions.
- The Hengxing Solution: Our dryer cylinders are equipped with custom anti-sticking chains and scraper flights that automatically clean the inner walls as the drum rotates. This is paired with advanced tail-gas deodorization and baghouse dust collection systems to meet strict environmental standards.

Types
Choose Your Dryer Type: Single Pass vs. Triple Pass
At Hengxing Machinery, we understand that identical materials may require completely different processing strategies based on your site conditions, budget, and operational goals. To provide truly customized solutions, we engineer two distinct structural designs for our rotary dryers, ensuring you get the exact performance and efficiency your plant demands.
Single Pass Rotary Dryer
The Single Pass Rotary Dryer is the undisputed heavy-duty workhorse of the industry. Designed with a classic, robust single-cylinder structure, it is engineered to handle massive processing capacities with unmatched durability. Because of its straightforward mechanical design, it is highly resistant to wear and tear, ensuring continuous, rugged operation in harsh environments while keeping your long-term maintenance costs exceptionally low.
This machine is the ultimate choice for large-scale mining operations, heavy mineral processing, and coal enterprises that demand massive daily outputs. It is perfectly suited for facilities without strict space limitations, where prioritizing sheer volume, heavy-duty tolerance, and continuous reliability is the primary operational goal.
Triple Pass (Three-Cylinder) Rotary Dryer
For operations where thermal efficiency and space-saving are paramount, our Triple Pass Rotary Dryer offers a revolutionary technical upgrade. This innovative design features three concentric cylinders nested together. This unique configuration allows the outer cylinder to effectively act as an insulation layer for the inner cylinders, resulting in an exceptionally high thermal utilization rate. Consequently, it drastically minimizes heat loss and saves a massive amount of fuel compared to traditional single-pass designs. Furthermore, this nested structure shrinks the equipment’s overall footprint by up to 60%.
We highly recommend the Triple Pass system for enterprises facing strict site space constraints or those highly sensitive to soaring operational fuel costs. It is the absolute best-in-class solution for drying granular, free-flowing materials such as river sand, frac sand, dry mortar, and fly ash.
