The FGM Series Ultrafine Grinding Sand Making Machine is designed to produce high-quality manufactured sand with higher fine sand output and better particle shape. It is a new-generation sand making equipment developed by FTM Machinery.
It combines crushing, shaping and grinding in one machine for fine sand production, significantly increasing the 0–3 mm fine sand proportion.
Applications of ultrafine grinding sand making machine
The ultrafine grinding sand making machine is designed to process medium- and low-abrasive materials.
It is widely used in concrete, asphalt, dry-mixed mortar and manufactured sand production lines.
- Concrete aggregate production: limestone, granite, river pebbles
- Asphalt mixing plants: basalt, diabase, cobblestone
- Dry-mixed mortar production: quartz, sandstone
- Manufactured sand production lines: dolomite, tailings materials
Why FTM Machinery FGM sand making machine?
More fine sand. Better gradation. Higher-value output.
- Higher fine sand output: Rotor speed up to 70 m/s, optimized for 0–3 mm sand production.
- Better particle shape: Crushing, shaping and grinding help produce more cubic particle content for concrete and asphalt applications.
- Capacity range: Models are available with capacities from 35–119 t/h, suitable for small to medium sand production plants.
- Stable gradation: The hammer–liner structure maintains a constant crushing gap, keeping particle size distribution stable even under normal wear conditions.
- Smart control system: Equipped with PLC + DCS control system for real-time monitoring and stable operation.
How does an ultrafine grinding sand making machine work?
Material enters the crushing chamber and is accelerated by the high-speed rotor.
Inside the chamber, materials are repeatedly crushed through impact, shearing, and grinding between the hammer head and liner plates. The specially designed crushing structure maintains a stable crushing gap throughout the process, allowing the material to be crushed and shaped at the same time.
Advanced structure of the ultrafine grinding sand making machine
The FGM ultrafine grinding sand making machine is mainly composed of the upper housing, crushing chamber, impeller assembly, hammer head, liner plates, hydraulic lifting device, transmission system, shock absorption base, and lubrication system.
1. Hydraulic lifting device
The hydraulic lifting system enables convenient opening and closing of the upper cover, providing larger maintenance space and improving the efficiency of inspection and replacement of wearing parts.
2. Impeller assembly
The impeller assembly is the core component. It is manufactured from high-strength alloy steel and optimized through dynamic balancing treatment. The impeller accelerates materials at high speed to improve crushing efficiency and sand shaping performance.
3. Hammer head
The machine adopts a unique horseshoe-shaped hammer head structure. The hammer heads are made of high wear-resistant alloy materials and can be used reversibly, effectively extending the service life and reducing maintenance costs.
4. Shock absorption base
Rubber shock absorbers are installed at the bottom of the machine to effectively reduce vibration and noise during operation while minimizing the impact on the foundation structure.
