Integrates core functions such as grinding, fineness control, efficiency enhancement, wear resistance, and particle uniformity. It grinds materials by rotating extrusion, with adjustable pressure to meet different fineness requirements. Made of high-hardness, wear-resistant materials for long service life and stable performance. Ensures even stress distribution to prevent over-grinding or under-grinding.
Works in tandem with the grinding roller to grind large particles into fine powder. It supports and guides the roller’s stable rolling path, ensuring materials are tightly pressed for efficient operation.
Feeds raw materials into the grinding area between roller and ring. Made of durable, wear-resistant material to withstand abrasive forces.
Controls the fineness of the final powder product by adjusting its rotational speed.
Transports the ground powder into the analyzer for classification via airflow.
Collects qualified fine powder after classification for packaging or further processing.
Connects all functional components and ensures continuous, stable airflow throughout the system.
Large raw materials are crushed to ≤30mm by a crusher to meet grinding requirements.
An electromagnetic vibrating feeder delivers materials evenly and continuously to ensure grinding stability.
The grinding roller presses the material against the rotating ring via centrifugal force, forming a grinding belt that crushes and shears the raw material into powder.
Powder is carried by airflow into the classifier; coarse particles fall back for regrinding, while qualified fine powder proceeds to collection. Fineness is controlled by classifier speed.
Qualified fine powder is collected by the cyclone collector and is ready for packaging or further use.
Production Capacity: 5~22t/h
Fineness: 80~325 mesh
Maximum Feed Size: 30mm
