Product Overview
The laboratory conical ball mill is a specialized batch-grinding apparatus designed for the fine reduction and homogenization of ore samples, minerals, rocks, and industrial raw materials. Engineered primarily for sample preparation prior to chemical, mineralogical, or physical analysis, this unit provides precise control over fine-grinding dynamics. Its distinctive conical cylinder design facilitates dynamic media classification during operation, ensuring that impact energy and grinding force are optimally distributed throughout the charge volume.
Widely utilized across metallurgy, geology, mining analytical labs, chemical engineering, and building materials sectors, this equipment serves as an indispensable tool for preparing head samples, concentrate evaluations, and flotation assay feeds. It seamlessly integrates into standard laboratory testing workflows, working alongside benchtop flotation cells, wet/dry sieving systems, and analytical spectrometers to provide highly representative, finely pulverized material for downstream testing.
Built for continuous duty and rigorous laboratory environments, the system features a robust drive mechanism coupled with a precision-machined heavy-duty mill cylinder. The combination of a balanced rotational speed and a scientifically proportioned steel ball charge guarantees reliable, repeatable performance. Laboratory technicians can depend on this unit to deliver uniform size reduction without thermal degradation or excessive sample contamination, ensuring total confidence in analytical outcomes.
Key Features
- Conical Cylinder Design for Optimal Media Classification: The specialized conical geometry of the drum encourages internal spatial sorting of grinding media during rotation, placing larger balls where impact forces are needed most and finer media where fine polishing occurs. This optimizes grinding kinetics and accelerates particle size reduction down to 200 mesh.
- Precision Speed Control and Gear Reduction: Powered by a heavy-duty industrial motor running at 1400 r/min, the drive train utilizes an integrated speed reduction assembly to maintain a steady cylinder rotational speed of 112 ± 2 r/min. This stable kinetic velocity ensures repeatable impact dynamics across sequential test batches.
- Optimized Multi-Size Steel Ball Charge: Supplied with a factory-calibrated 3.6 kg steel ball media charge comprising three distinct ball diameters (25 mm, 20 mm, and 15 mm). The carefully engineered mass ratio (42% large, 33% medium, 25% small) maximizes inter-ball contact points while maintaining maximum impact energy for efficient fragmentation.
- High-Fineness Single-Pass Processing: Designed specifically to handle feed particle sizes up to ≤ 3 mm and reduce them to a fine 200 mesh output in a single batch cycle. This high reduction ratio drastically shortens laboratory preparation time and improves mineral liberation for subsequent metallurgical testing.
- Compact 1 Liter Capacity Sealed Chamber: The 150 mm diameter by 50 mm length cylinder features a total internal volume of 1 liter, tailored specifically for processing typical batch sample masses of up to 200 grams. The secure closure system prevents fine dust release and sample loss during high-speed rotation.
- Seamless Workflow Integration: Ideal as a precursor preparation step for flotation testing, magnetic separation, or analytical assaying. The consistent particle size distribution achieved by the unit minimizes variability in laboratory flotation recovery rates and spectroscopic analyses.
- Industrial-Grade Construction & Motor Assembly: Built with an AO2-7114 standard 0.25 kW industrial motor, the unit operates with high mechanical efficiency, minimal vibration, and low thermal output, ensuring low maintenance overhead and extended service life in demanding laboratory environments.
