Feeding and Conveying (Material Preparation):

The raw material is crushed to particles smaller than 20 mm and lifted by the bucket elevator to the storage hopper. A frequency-controlled vibrating feeder ensures a continuous and uniform material flow into the grinding chamber, preventing mechanical overload.

HGM Main Unit (Multi-Layer Grinding System):

The core of the production line, featuring a unique 4-layer grinding design. Utilizing centrifugal force, the rollers crush, roll, and shear the material against the rings. This multi-stage grinding logic delivers significantly higher fineness and throughput compared to traditional impact mills.

Multi-Impeller Classifier (Precision Screening):

Integrated at the main unit’s top, this advanced classifier features five independent frequency-controlled motors. By optimizing centrifugal airflow through synchronized multi-rotor rotation, it precisely adjusts the D97 cut-off point (325–3000 mesh), ensuring a sharp particle size distribution and highly efficient ultra-fine powder collection.

Pulse Dust Collector (Environmental Protection):

This high-efficiency tank-type collector utilizes premium filter bags to capture 100% of the finished powder directly from the airflow. Operating under negative pressure, it ensures zero dust leakage and a 99.9% recovery rate, making it ideal for ultra-fine applications where total product recovery is critical.

High-Pressure Blower (Airflow Circulation):

The “lungs” of the system, providing the necessary negative pressure and high-velocity airflow to lift and transport the powder. Equipped with a professional silencer, it ensures a stable pneumatic environment for the entire closed-loop grinding circuit.

PLC Intelligent Control System (Centralized Operation):

The “brain” of the plant, allowing engineers to monitor vibration, motor frequency, temperature, and system pressure in real-time. This automated interface ensures high batch-to-batch consistency and protects the equipment through intelligent fault-diagnostics and emergency shutdowns.
