Quartz Sand Dryer—A drying solution specifically designed for glass sand, slab sand, and filter media
The Tongding quartz sand drying production line is specifically designed for materials characterized by high hardness and chemical stability, including quartz sand, slab sand, and glass sand. It is widely used in sectors such as glass manufacturing, engineered stone production, and water treatment filtration.
Product Overview
Quartz sand, slab sand, and glass sand are characterized by high hardness and chemical stability, making them important raw materials in fields such as glass manufacturing, engineered stone production, and water filtration.
This wet sand has a high moisture content. Traditional drying methods often lead to particle breakage and the excessive loss of fines, thereby compromising the material's purity and integrity. The Tongding quartz sand dryer is specifically designed to handle such demanding materials; it utilizes patented lifting-flight technology to efficiently remove moisture while preserving the particle structure.
The equipment has been exported to Russia, Kazakhstan, Kyrgyzstan, Uzbekistan, and various Southeast Asian countries, serving industries such as glass, engineered stone, casting, and water treatment.
Equipment Advantages
Patented lifting structure—ensures uniform drying without damaging the granules.
The core drying system integrates multiple patented technologies, including multi-bend and serrated lifters. The combined design of these two types of lifters creates a continuous, curtain-like "waterfall" of material within the drum, maximizing heat exchange efficiency between the material and the hot air.
Drying uniformity exceeds 95%, effectively removing moisture while preventing granule breakage caused by excessive tumbling. Loss of fines is minimized, ensuring the cleanliness and integrity of the finished sand.
Highly wear-resistant core components—service life extended by 4 to 7 times.
Key components of the dryer are constructed from high-strength wear-resistant steel plate, delivering 4 to 7 times longer service life than ordinary manganese steel. The support rollers and tire rings are manufactured from high-hardness steel, offering 3 to 5 times greater wear resistance than conventional equipment.
Maintenance is simple – only routine outer-diameter turning is required annually, significantly reducing downtime and maintenance costs.
Precise Temperature Control – Energy Efficient Operation
The combustion chamber is designed for natural gas firing, constructed with high-temperature resistant materials and a specialized structure that withstands temperatures up to 1400°C. Thermal shock resistance is excellent, ensuring long-term stable operation.
Temperature control is precise. Exhaust gas temperature is maintained at approximately 70°C, while the discharged sand temperature remains stable at around 60°C. This minimizes energy waste and eliminates the need for additional cooling before the sand enters subsequent processing stages.
High-Efficiency Induced Draft System – Stable Operation
The induced draft system is scientifically designed to ensure smooth ventilation and efficient operation. Vertical plates divide the space between the inner and outer drums into 8 independent drying chambers. Material distribution is uniform, drying is more energy-efficient, and the design prevents heavy-load startup issues during power outages, ensuring equipment safety and stability.
Environmental Compliance & Installation
Dust Emission Below Standards
Equipped with a pulse dust collector, emission concentration is controlled within 10 to 30 mg/Nm³, meeting environmental compliance requirements. Dust is effectively contained during production, ensuring a clean workshop environment and compliance with local environmental regulations.
Stable Foundation Design – Quick Installation
The foundation design uses pre-embedded anchor bolts instead of traditional embedded plates, improving equipment leveling and fixation performance. Combined with a secondary grouting process, overall stability is enhanced, preventing displacement or settlement during long-term operation.
Materials & Applications
