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, ensuring a sharp particle size distribution and efficient 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.

To ensure a seamless transition to efficient production, our engineering team provided expert on-site guidance throughout the installation and commissioning phases of the Macedonian project. Leveraging heavy crane equipment, the core grinding components—including the main unit, drive motor, and multi-impeller classifier—were meticulously hoisted, aligned, and securely seated over the foundation pit to guarantee perfect vertical alignment and structural stability. Following mechanical assembly, our team fine-tuned the multi-impeller classifier and high-efficiency blower system to optimize internal airflow dynamics, ensuring the plant can adapt flexibly across the client’s wide 200 to 2,500 mesh (74–5μm) output requirements before concluding with full-load calcite testing and hands-on operator training.

If you are in the mining, construction, or mineral processing industry, you already know that raw materials alone don’t yield the highest profits. When it comes to gypsum, the real commercial value lies in processing. Many plant owners and investors ask: Why should we invest in a calcination and grinding line instead of just selling raw gypsum o…
