Sand and Gravel Dust-Removal and Separation Line
The mineral powder drying and classification line is an integrated system combining the processes of drying, classification, conveying and environmental cleaning. It is widely used for processing materials such as slag powder, limestone powder, fly ash and other bulk materials.
The system is equipped with a high-efficiency heat source and optimized drying equipment, which ensures rapid and uniform moisture removal through rational organization of gas flows and precise temperature control. At the same time, a high-efficiency classifier is used, ensuring accurate classification and stable fineness of the finished product in accordance with the requirements of various fields of application.
The entire line is characterized by a high degree of automation, stable and reliable operation, low energy consumption, high productivity and a compact layout. An efficient dust collection system helps reduce dust emissions and comply with modern environmental standards.
Depending on the characteristics of the raw material and the productivity requirements, the process flow can be flexibly adapted to the customer's needs, ensuring maximum energy efficiency and economic benefit.

Receiving hopper for raw mineral powder
The receiving hopper is used for receiving and storing raw mineral powder before drying. Its volume can be configured according to the user's needs, and the bottom outlet connects to the belt feeder. The design is compact, rational, sturdy and durable.
Belt weigh feeder
The belt weigh feeder combines the functions of conveying, weighing and precise dosing. It ensures continuous, stable and adjustable feeding of bulk materials into the line, and the automatic control system maintains the set productivity in real time.
Rotary drum dryer
The rotary drum dryer is designed to reduce the moisture content of slag, limestone powder, iron powder and other bulk materials to the required level before further grinding, classification or storage. The wet material enters the drum, is heated by hot air, after which the moisture evaporates and the dry material is discharged.
The dryer can operate on a co-current or counter-current principle. The internal lifting flights effectively mix the material, increasing the heat exchange area and improving drying efficiency.
Air classifier
The air classifier uses a high-speed air flow to separate materials by particle size, density and other physical characteristics. It effectively separates fine particles from coarse ones, ensuring production of products with the required dispersion.
By adjusting the air flow and the speed of the rotor wheel, the separation process can be precisely tuned to the requirements of the specific material and finished product.
Pulse-jet bag filter
The pulse-jet bag filter is high-efficiency dry dust collection equipment operating on the principle of filtration through bags and pulse cleaning with compressed air. The dust-laden gas enters the filter, the dust is retained on the surface of the bags, and the cleaned gas is discharged from the system.
The pulse jet drops the accumulated dust into the hopper, thanks to which the filter steadily maintains high cleaning efficiency and meets modern environmental requirements.
