Clirik Solution: HGM125L Ultrafine Grinding Mill
Equipment Configuration: Storage hopper,screw conveyor, grinding main unit, classifier, blower,dust filter, electronic control cabinet.
Service Support: On-site installation guidance by professional installation engineers.
Project Background
Uganda possesses rich, high-purity marble reserves, but local manufacturers long relied on costly imported fine powder for coatings and construction. To capture higher value, a top local mining enterprise decided to build an advanced in-house grinding line to process raw marble directly into high-grade ultrafine powder (325–2500 mesh).
To tackle the hard raw stone while preserving maximum whiteness and avoiding iron contamination, the client chose Shanghai Clirik’s HGM125L Ultrafine Grinding Mill.With its high-chromium alloy rollers and intelligent VFD classifier, the HGM125 delivered high output, precise fineness control, and low energy consumption. Today, the project serves as a modern, eco-friendly benchmark for mineral processing in East Africa.

Feeding and Conveying (Material Preparation):
Raw material in FIBCs is unloaded via a dust-proof discharging station into the buffer hopper. In place of a traditional feeder, a loss-in-weight screw feeder is employed to deliver a precise, constant flow into the mill. This setup guarantees a continuous, uniform feed that prevents mechanical overload and ensures optimal grinding efficiency with minimal dust emission.
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.
High-Efficiency Classifier (Precision Screening):
Integrated at the top of the main unit, this variable-frequency classifier uses centrifugal airflow to separate particles. It allows for the precise adjustment of the D97 cut-off point between 325 and 3000 mesh, ensuring that only the qualified ultra-fine powder proceeds to the collection stage.
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.

When the machine arrived in Uganda, our engineers were right there on site to guide the entire setup. Facing local site challenges, we worked side-by-side with the client’s local team to assemble every part, carefully align the grinding rollers, and adjust the classifier system.
After thorough testing and trial runs, the HGM125 mill hit the target powder fineness on its very first full test run. Before leaving, our engineers gave hands-on training to the local workers, making sure they knew how to operate and maintain the plant with confidence.
Our professional installation and commissioning service ensures your grinding system transitions smoothly from delivery to full-scale production. We dispatch senior engineers to your site to oversee the entire mechanical assembly, ensuring every component—from the HGM mill to the precision feeding system—is aligned with exacting standards. Beyond physical installation, we conduct rigorous system commissioning, fine-tuning the operational parameters to achieve your target fineness and output while ensuring the localized dust collection systems perform at peak efficiency.
Industrial Transformation
Uganda is actively pushing for industrialization to reduce its heavy reliance on imported fine mineral powders. Supported by national growth initiatives, the local manufacturing sector is expanding rapidly. This creates a strong demand for advanced grinding solutions that enable local processing of raw marble and limestone into high-value ultrafine powders.
Infrastructure & Operations
Industrial expansion across Uganda faces operational challenges, such as unstable power grids in remote mining regions. As a result, equipment buyers strongly prioritize energy-efficient grinding mills and low-maintenance machinery that offer reliable performance and minimal downtime under demanding local operating conditions.
Turnkey & Skills Demand
The local market experiences a shortage of experienced technicians for complex industrial systems. Powder manufacturers increasingly seek suppliers offering complete, end-to-end solutions. Delivering comprehensive installation guidance, VFD-integrated automated controls, and hands-on operational training provides a decisive competitive edge.
