Product Overview
This advanced sealed hammer cutter crusher represents an integrated sample preparation solution designed to combine impact and shear compound crushing mechanisms within a completely dust-tight enclosure. Engineered specifically to tackle difficult, sticky, or high-moisture bulk raw materials with moisture levels up to 15%, the system delivers rapid size reduction without sample degradation, thermal moisture loss, or cross-contamination. By combining continuous fine crushing with an integrated automated sample division mechanism, the equipment converts bulk raw feed directly into representative laboratory samples in a single seamless pass.
Purpose-built to meet stringent sample preparation standards such as GB474 (Method for Preparation of Coal Samples) and GB/T18666 (Method for Check and Acceptance of Commercial Coal Quality), this equipment serves as an indispensable asset across coal processing plants, thermal power generation facilities, metallurgical works, building material labs, chemical processing units, geological survey stations, and material science research institutions. Whether processing run-of-mine coal, metallurgical coke, dense alloy lumps, or high-hardness sintered pellets, the system ensures uniform particle size reduction and statistically reliable sample splitting.
Constructed with a heavy-duty precision-cast steel crushing chamber and high-strength Ni-WC35 nickel-based tungsten carbide alloy coated hammers, this system maintains exceptional structural integrity and wear resistance during continuous, high-throughput operations. The dust-free housing and smooth internal geometry prevent material accumulation, eliminating sample retention dead zones while safeguarding laboratory personnel from airborne particulates. Its robust design guarantees operational consistency and repeatable analytical results across demanding industrial sample preparation workflows.
Key Features
- Dual Compound Crushing Mechanism: Combines high-velocity kinetic impact with aggressive shearing force to rapidly break down medium-hardness ores, sticky coal, and high-strength aggregates without causing chamber clogging or thermal degradation.
- Ultra-Wear-Resistant Ni-WC35 Alloy Hammers: Features premium nickel-based tungsten carbide (Ni-WC35) alloy coated hammers engineered for extreme hardness and abrasion resistance, permitting continuous processing of tough minerals, ferroalloys, coke, and sintered pellets.
- Symmetrical Arc Hammer Design: Utilizes an aerodynamically and mechanically optimized symmetrical arc profile that allows reversible operation, effectively doubling the usable wear life of the hammers and reducing operational maintenance costs.
- Fully Sealed Zero-Dust Architecture: Incorporates complete structural sealing across all operational chambers and material transfer paths, eliminating airborne dust emissions to satisfy strict workplace hygiene standards while preventing sample loss and cross-contamination.
- Precision Cast Steel Crushing Chamber: Heavy-wall precision casting provides extreme structural rigidity and thermal stability, preventing localized sample overheating during intense mechanical action and preserving accurate total moisture content.
- Integrated Stainless Steel Sample Division System: Integrates a jam-free stainless steel rotary divider directly below the crushing zone, allowing seamless sample reduction at adjustable division ratios from 1/2 down to 1/8 in a single continuous process.
- Quick-Change Plug-In Sieve Plates: Features a modular plug-in screen grid mechanism that enables rapid tool-free replacement of sieve plates (offering 1mm, 3mm, 6mm, and 13mm output thresholds) for flexible particle size distribution control.
- Non-Clogging Full-Section Crushing Geometry: Designed with a streamlined, dead-zone-free internal chamber layout that ensures complete material throughput, preventing sticky or high-moisture samples (up to 15% moisture) from building up or bridging.
- Comprehensive Mechanical Safety Guarding: Outfitted with robust protective enclosures over all belts, pulleys, and motor drive transmissions, ensuring operator safety and full compliance with modern industrial machine safety regulations.
- Low-Noise Smooth Drive Transmission: Powered by balanced electric motors coupled with precision drive shafts, delivering quiet, vibration-isolated operation even under heavy crushing loads in continuous laboratory environments.
Applications
| Application | Description | Key Benefit |
|---|---|---|
| Coal Mining & Preparation | Processing run-of-mine coal, washed coal, and refuse fractions with up to 15% moisture content down to <1mm or <3mm for calorific, ash, and volatile analysis according to GB474 standards. | Prevents moisture loss during rapid crushing while integrated splitting ensures statistically representative sample preparation. |
| Power Generation & Thermal Plants | Rapid size reduction of incoming commercial coal shipments for quality verification and acceptance testing under GB/T18666 compliance protocols. | Rapid processing throughput up to 3000 kg/h with automated sample splitting minimizes laboratory sample preparation turnaround time. |
| Metallurgical & Ferroalloy Labs | Crushing high-strength materials including metallurgical coke, sintered iron ore pellets, and hard alloy lumps using tungsten carbide hammers. | Ni-WC35 carbide coating prevents hammer deformation and minimizes sample contamination from heavy metal wear particles. |
| Building Materials & Cement Production | Grinding limestone, clinker, gypsum, and raw meal samples prior to X-ray fluorescence (XRF) pelletizing or elemental composition testing. | Quick-change sieve plates allow instant adjustment between coarse crushing (13mm) and fine product output (<1mm). |
| Chemical & Petrochemical Processing | Crushing sticky chemical aggregates, synthetic polymers, and solid catalyst beds under fully sealed conditions. | Complete dust isolation protects operators from toxic dust while preventing environmental moisture absorption or sample loss. |
| Geological Survey & Mining Exploration | Pulverizing rock cores, ore minerals, and exploration soil samples to prepare representative sub-samples for fire assay or ICP spectroscopy. | Non-clogging full-section chamber prevents sample cross-contamination between consecutive geological core runs. |
