Product Overview
This high-frequency electromagnetic ore pulverizer is a specialized laboratory sample preparation unit engineered for rapid particle size reduction of hard, brittle, and fibrous materials. Utilizing advanced electromagnetic induction principles, the system directly energizes the grinding vessel mechanism to generate high-frequency kinetic impacts at approximately 3,000 vibrations per minute. This intense dynamic action pulverizes raw material feeds into ultra-fine analytical powders in seconds, offering an efficient alternative to traditional manual mortars and mechanical jaw or disc grinding apparatuses.
Designed to meet the rigorous demands of modern testing facilities, this equipment is widely deployed across mining exploration, cement manufacturing, building materials, metallurgy, chemical processing, coal analysis, and agricultural grain quality verification laboratories. It is particularly effective for preparing challenging fly ash samples in thermal power stations, where fast turnaround and sample uniformity are essential for reliable chemical and physical assays.
Built with an emphasis on operational efficiency and operator comfort, the pulverizer features a compact benchtop footprint, low operating noise, and a dust-suppressed architecture. Its maintenance-free electromagnetic drive eliminates mechanical wear parts, ensuring long-term operational consistency, dependable accuracy, and reduced maintenance overhead under high-throughput laboratory workloads.
Key Features
- Electromagnetic Impact Drive: Employs direct-drive electromagnetic attraction technology to generate 3,000 high-frequency impacts per minute, accelerating material comminution without relying on complex mechanical transmission components.
- Sub-200 Mesh Particle Reduction: Efficiently processes raw feed sizes up to 15 mm down to less than 200 mesh (74 microns) output, enabling direct spectroscopic or wet chemical analysis without requiring subsequent manual sieving.
- Rapid Processing Cycles: Features a fully adjustable analog/digital timer from 0 to 5 minutes, with standard analytical sample preparation completed in under 2 minutes for maximum laboratory efficiency.
- Dust-Free and Low-Noise Operation: Engineered with fully sealed grinding vessels and sound-dampened housings to maintain a safe, clean, and quiet laboratory environment free from airborne particulates.
- Dedicated Sample Cup System: Supports custom configurations of dedicated sample cups designed for specific material types, eliminating cross-contamination risk and removing the need for tedious post-grinding cleaning procedures.
- Compact Benchtop Footprint: Measures just 220 × 250 × 250 mm with a total weight of 18 kg, allowing flexible installation on standard laboratory workbenches without occupying valuable space.
- Energy-Efficient Single-Phase Power: Operates on a standard 220V 50Hz electrical supply with a nominal 6A current drawing requirement, ensuring easy integration into standard electrical infrastructure.
