Sealed Hammer Crusher for Laboratory Sample Preparation Powder Processing and Hard Mineral Reduction

Product Overview

This high-efficiency sample preparation system is a heavy-duty sealed hammer crusher specifically engineered for rapid, uniform size reduction of medium-to-hard minerals, ores, coal, and industrial byproduct samples. Built in strict accordance with national sample preparation standards (GB474-1996), this unit provides exceptional particle size control, enabling analytical testing facilities to achieve accurate, repeatable, and non-biased sample preparation for downstream elemental and physical characterization.

The operational mechanism relies on a dynamic, high-speed rotating hammer core assembly enclosed within a reinforced crushing chamber. As the internal rotor spins at high velocity, heavy-duty centrifugal hammers swing outward to form a continuous impact ring. Material fed into the top chamber undergoes immediate cyclic impact crushing against the high-velocity hammer heads and internal breaker liners. The pulverized material is subsequently forced through pre-selected bottom sieve plate perforations, guaranteeing consistent discharge sizes such as 3 mm, 6 mm, or 13 mm.

Designed for demanding daily duty cycles, the equipment features a fully dust-sealed body that eliminates fine particle escaping, safeguards operating personnel, and prevents laboratory cross-contamination. Its robust structural framework, heavy-gauge housing, and specialized alloy wear components deliver reliable long-term performance across demanding industrial sectors, including coal mining, metallurgy, thermal power generation, cement manufacturing, chemical processing, and environmental monitoring.

Key Features
