Product Overview
This specialized grinding system represents an advanced solution for small-scale fine and ultra-fine sample preparation in material science and mineral research laboratories. Designed with an engineered conical drum geometry featuring a wide feed end and a narrowed discharge end, the equipment naturally stratifies feed material during rotation. Coarse feed particles undergo heavy-impact crushing by steel rods at the wide end, while progressively finer material naturally migrates toward the narrow end for refined grinding. This progressive size-reduction dynamic minimizes unwanted over-crushing, ensuring a remarkably tight particle size distribution and superior sample integrity.
Built for high-efficiency metallurgical, geological, and industrial material testing, this equipment is widely applied across mineral processing laboratories, coal research centers, and building material testing facilities. The system exhibits outstanding process flexibility by accommodating both dry and wet grinding operations. Furthermore, the unit seamlessly converts between rod mill and ball mill configurations simply by interchanging the internal grinding media from steel rods to steel balls, making it a versatile asset for diverse analytical protocols and batch milling requirements.
Engineered for maximum reliability and repeatability under demanding laboratory conditions, the equipment eliminates operational inconsistency and physical strain through complete motorized automation. Electric control systems automate feeding, discharging, and drum elevation, eliminating manual handling errors and operator fatigue. Complemented by a clear LCD digital interface, this unit provides precise control over grinding durations, delivering dependable, repeatable, and high-throughput sample grinding performance batch after batch.
Key Features
- Engineered Conical Drum Geometry: The uniquely tapered drum design naturally stratifies material during rotation, directing coarse feed to the wide impact zone and finer particles to the narrow grinding zone to prevent over-milling and deliver an exceptionally uniform product.
- Convertible Rod and Ball Media System: Offers flexible dual-functionality by allowing effortless conversion between steel rod and steel ball media, enabling users to perform both impact rod milling and high-density ball milling on a single platform.
- Full Electric Motorized Automation: Integrated motorized control mechanisms automate the loading, tilting, elevation, and discharging operations, completely eliminating manual handling hazards, operator fatigue, and positional errors.
- Programmable Digital LCD Controls: Features an intuitive LCD menu interface that allows laboratory technicians to precisely configure and monitor grinding times, ensuring strict compliance with standard operating procedures and test repeatability.
- Versatile Dry and Wet Grinding Capabilities: Capable of processing dry powders as well as wet liquid-solid suspensions and mineral slurries without altering the internal grinding setup or compromising drum seal integrity.
- Heavy-Duty Roller Drive Architecture: Built with precision-machined support rollers running at optimized rotational speeds (140 to 160 rpm) to establish consistent friction and centrifugal forces, ensuring optimal rod cascading and maximum impact energy.
- High-Throughput Batch Processing Capacity: Designed to accommodate multiple cylinder configurations and high single-batch sample volumes, dramatically increasing processing efficiency for analytical and pilot-scale testing.
- Wear-Resistant Industrial Construction: Fabricated using premium wear-resistant materials and robust structural components capable of handling abrasive ores, hard ceramics, clinker, and coal without contamination or premature mechanical wear.
