It is commonly used to dry river sand, artificial sand, quartz sand, mineral powder, coal slag, etc.
Efficient Sand Drying Solution
A MACHINE YOU CAN DEPEND ON!
High-efficiency sand dryer, specially designed for wet sand, quickly reduces moisture and increases production. Advanced hot air technology ensures uniform drying, saves energy and electricity, and is an ideal choice for sand processing
The three-channel dryer adopts a complex triple hot air channel design, and its multi-channel structure significantly improves thermal efficiency and drying quality. By optimizing the airflow path, this design can effectively reduce heat loss, increase the equipment's processing capacity by more than 20%, and ensure uniform drying of materials.
The inner wall of each layer of the cylinder is equipped with specially designed lifting plates, which throw and scatter the material, increasing the contact area between the material and the airflow, thereby significantly improving the drying rate. This design also extends the length of the working section, shortening the drying time of each batch of materials by 30%, ensuring efficient processing.
The triple hot air channel design makes the heat exchange process more flexible, and the material can be processed in the equipment by direct or indirect heating. This special structural design improves the utilization efficiency of thermal energy, which can reach more than 85% of the thermal energy utilization efficiency, reducing energy consumption and meeting environmental protection requirements.

In construction projects, when wet sand is mixed with cement, excessive moisture content will affect the strength and stability of concrete. Excessive moisture will prevent the cement in the concrete from fully combining with the sand, thereby reducing the strength and durability of the concrete. Dried sand can ensure that the concrete ratio is accurate, meet the design requirements, and improve the safety and durability of the building.
The high moisture content of wet sand causes its weight to increase, thereby increasing transportation costs. At the same time, wet sand is prone to agglomeration during storage, which not only affects storage efficiency, but may also cause damage to storage facilities. Through drying treatment, the moisture content of sand can be significantly reduced, transportation costs can be reduced, and storage can be made more convenient and efficient.
In industrial applications such as glass manufacturing, casting and other fields, wet river sand may cause equipment damage or low production efficiency. The moisture in wet sand is easily converted into steam under high temperature conditions, causing equipment overheating or unnecessary bubbles. Dried river sand can prevent these problems and ensure the stability and efficiency of the production process
Dry sand is an indispensable material in the construction industry. In house construction, dry sand is used to lay floor tiles, wall tiles, etc. It is also the main component of cement mortar, which is used for bricklaying and exterior wall painting. The solidification strength of cement mortar depends largely on the use of sand. Without sand, the solidification strength of cement mortar is basically zero.
Dried sand can be used for casting and for making molds for various metal parts. After specific treatment, dry sand can be used for sewage treatment, helping to purify water through procedures such as sand filtration and backwashing.
In the glass manufacturing process, it is mixed with other materials and melted at high temperatures to form glass.
Dry sand can also be used to make refractory materials and ceramics, which remain stable at high temperatures and are used in various industrial and daily life purposes.
The sand is sent to the hopper by a belt conveyor or bucket elevator, and then enters the feeding end through the feeding pipe of the hopper feeder. The inclination of the feeding pipe should be greater than the natural inclination of the material so that the material can flow smoothly into the sand dryer (yellow sand dryer).
The dryer cylinder is a rotating cylinder slightly inclined to the horizontal line. The material is added from the higher end, and the heat carrier enters from the lower end, and contacts with the material in countercurrent. There are also cases where the heat carrier and the material flow into the cylinder together.
As the cylinder rotates, the material moves to the lower end under the action of gravity. During the process of the wet material moving forward in the cylinder, it directly or indirectly receives heat from the heat carrier, so that the wet material can be dried, and then sent out at the discharge end through a belt conveyor or a screw conveyor.
A shoveling plate is installed on the inner wall of the sand dryer (yellow sand dryer) cylinder. Its function is to scoop up and scatter the material, so that the contact surface between the material and the airflow is increased to increase the drying rate and promote the advancement of the material.
A single-channel dryer has a simple structure consisting of a long cylinder and a single hot air channel. The contact between the hot air and the material is relatively limited, and the drying process is relatively simple. The three-channel dryer uses a complex triple hot air channel design to optimize the heat exchange process and provide a more uniform drying effect.
Its multi-channel structure can significantly improve thermal efficiency and drying quality. Due to its optimized hot air flow path, the three-channel dryer can use heat energy more effectively and has a more uniform drying effect than the single-channel dryer. The relatively low thermal efficiency of the single-channel dryer may lead to uneven drying, especially when processing large quantities of materials.
Although the initial equipment investment of the three-channel dryer is high, due to its efficient heat utilization, the long-term energy consumption is low, thereby reducing the overall operating cost. At the same time, the civil construction cost is more economical than that of the single-channel dryer. In contrast, the single-channel dryer has a lower initial investment, but due to its low energy efficiency, the operating cost is relatively high.
The three-channel dryer achieves self-insulation through the multi-layer drying channel design, which effectively improves the thermal energy utilization rate of the equipment. The multi-layer channel is characterized by the flow of dry air in a complex path to form a multi-layer heat exchange system.
This multi-layer structure not only increases the transmission length of the hot air, but also increases the contact time of heat exchange, so that the heat can be fully released and utilized in the multi-layer channel structure. Since the channel is a multi-layer structure, heat conduction is fully carried out between the layers, thus achieving efficient self-insulation.
