Product Overview
This laboratory-grade double roll crushing system is engineered specifically for ultra-clean, high-precision sample comminution of high-purity and high-hardness materials. By utilizing dense, high-purity zirconia ceramic (ZrO2) crushing rolls, the unit eliminates heavy metal and transition metal contamination—such as iron, chromium, and nickel—during the size reduction process. It provides an ideal roll-squeezing mechanism capable of processing tough, abrasive, and brittle feed samples while preserving pristine purity for downstream trace elemental and phase composition analysis.
Designed to meet the stringent demands of analytical testing and advanced material R&D, this equipment serves key sectors including metallurgy, geology, power generation, chemical synthesis, battery research, and advanced ceramics. It handles feed materials up to 13 mm in particle size and compresses them into highly uniform fractions down to sub-millimeter scales. The robust sealed construction ensures dust-free operational compliance within cleanroom and analytical laboratory environments.
Built with a heavy-duty frame, precision differential speed gearing, and high-torque electric drives, this crushing unit provides dependable, continuous performance even under heavy daily workloads. Its flexible clearance adjustment and non-stick ceramic surfaces ensure optimal throughput, minimal sample loss, and repeatable sample preparation across multi-stage testing workflows.
Key Features
- High-Purity Zirconia Ceramic Rolls: Manufactured from dense, stabilized ZrO2 ceramic with a Mohs hardness rating exceeding 8.5. These ultra-hard crushing rolls deliver exceptional resistance to wear and chemical attack, guaranteeing zero metal ion contamination (such as iron or chromium) to maintain absolute analytical sample integrity.
- Differential Speed Compression Technology: The opposing ceramic rolls rotate at precisely calculated differential speeds to apply simultaneous compressive squeezing and interfacial shearing forces. This dual-action comminution efficiently shatters hard mineral grains and dense synthetic compounds while maintaining uniform particle output.
- Micro-Adjustable Gap Calibration (0.1 to 5.0 mm): Featuring an intuitive mechanical gap adjustment system, operators can rapidly set and lock the distance between rolls from 0.1 mm to 5.0 mm. This precise gap control enables seamless transition between coarse primary crushing and fine secondary size reduction across diverse sample types.
- Anti-Adhesive Surface Treatment: The engineered zirconia roll faces undergo specialized surface finishing to eliminate surface sticking and material buildup. This non-stick characteristic allows smooth processing of cohesive, sticky, or moist samples, such as soft coals, hydrated minerals, and fine particulate aggregates.
- Fully Enclosed Eco-Sealed Housing: Built with an airtight, dust-proof containment enclosure that traps airborne particulates generated during high-speed crushing. This sealed design protects laboratory technicians from hazardous dust exposure, prevents cross-sample contamination, and minimizes material loss.
- Industrial High-Torque Power Delivery: Powered by continuous-duty three-phase electric motors ranging from 1.5 kW to 3.0 kW. The heavy-duty drive train maintains stable rotational velocity under maximum feed loads, ensuring smooth operation even when crushing dense ceramics or metallic ores.
- Quick-Access Maintenance & Cleaning: Engineered with accessible housing covers and ceramic roll assemblies, allowing rapid, thorough cleaning between batches to prevent cross-contamination in high-throughput analytical testing facilities.
