Three Cylinder Sand Dryer

The Three Cylinder Sand Dryer is a high-efficiency industrial drying system engineered for rapid moisture removal from bulk materials. Its three-drum design enhances heat utilization, reduces energy waste, and ensures uniform drying across diverse materials, making it ideal for large-scale production environments.

Applicable materials:

River sand, dry mortar, yellow sand, cement factory slag, clay, coal gangue, mixed materials, fly ash, straw powder, wood chaff, etc.

Capacity:  5-90 t/h

Diameter:1.5-4.2 m

Length:3-8.5 m

Power:  4.4-74 kW

Weight:  6-70 Tons

Rotational speed:  2-7.5 r/min


Description

The three-drum dryer represents an innovative and environmentally friendly drum drying solution, characterized by its compact footprint, high thermal efficiency, energy conservation, and eco-friendliness. Compared to traditional drying equipment, the three-drum dryer offers superior performance, aligning more effectively with the demands of modern urban development. Its unique three-cylinder nested structure ensures optimal heat utilization, thereby achieving high efficiency, energy savings, and environmental protection. This equipment is particularly well-suited for materials with high fluidity such as river sand, machine sand, mineral sand, and mineral powders. A variety of heat sources are available, including coal, electricity, natural gas, biomass technology, steam, and other renewable energy options.

Working Principle

Three Cylinder Sand Dryer
1. Material Input : Wet feedstock is evenly fed into Inner cylinder via a conveyor belt. 2. Heat Circulation : High-temperature air (generated by gas, coal, or electric heaters) flows through the drums. 3. Tumbling Action : As drums rotate, materials are repeatedly lifted and dropped, exposing maximum surface area to heat. 4. Moisture Extraction : Evaporated moisture is expelled via an exhaust fan, while dried material progresses to subsequent drums. 5. Output : Fully dried product is discharged from the outer cylinder, ready for packaging or further processing.

FAQ

A: Materials with extreme stickiness, explosiveness, or high oil content may require specialized adaptations. Consult our engineers for tailored solutions.
A: Yes! The adjustable low-temperature mode (50–90°C) preserves product quality without compromising drying speed.
A: Cycle time depends on material type and initial moisture content, typically ranging from 10 minutes to 2 hours.
A: No. The machine arrives pre-assembled, with plug-and-play operation. We provide remote guidance or on-site installation support.
