Overview
The MB Lab Jaw Crusher Model 010A-019 is a precision-engineered, single-toggle laboratory-scale jaw crusher designed for consistent size reduction of brittle, medium-hard to hard materials in research laboratories, quality control facilities, and pilot-scale processing environments. Based on classical compressive crushing mechanics, the unit operates via a fixed jaw and a moving jaw driven by an eccentric shaft, generating controlled compressive force to fracture feed material through mechanical stress concentration at grain boundaries. Its robust architecture supports repeatable sample preparation for downstream analytical workflows—including X-ray fluorescence (XRF), inductively coupled plasma (ICP) analysis, sieve analysis, and geochemical assay—where particle size uniformity and contamination control are critical.
Key Features
- Single-toggle kinematic design with precisely machined eccentric shaft, delivering synchronized horizontal and downward motion for efficient material compression and improved feed flow.
- Replaceable, reversible corrugated jaws fabricated from heat-treated AISI 4140 alloy steel (Brinell hardness 460 HB), optimized for wear resistance and consistent crushing performance.
- Manual handwheel-adjustable discharge opening, enabling fine-tuned control over product size down to 6.35 mm (¼ inch) without tooling or disassembly.
- Heavy-duty cast iron alloy frame with replaceable bronze bushings in both pitman and main frame bearings—designed for long service life under intermittent or semi-continuous operation.
- Pre-assembled on structural tubular steel base with Totally Enclosed Fan-Cooled (TEFC) motor, V-belt drive system, flywheel guard, and integrated feed hopper—ready for immediate installation and operation.
- Multi-voltage compatibility: configurable for 230–460 V / 3-phase / 60 Hz, 380 V / 3-phase / 50 Hz, or 575 V / 3-phase / 60 Hz power supplies to meet global facility standards.
Sample Compatibility & Compliance
The 010A-019 is suitable for crushing dry, non-fibrous, non-sticky materials with Mohs hardness ≤ 7, including ores, rocks, ceramics, slag, concrete aggregates, and sintered metal powders. It is not recommended for highly abrasive materials containing >15% free silica without enhanced wear protection, nor for ductile, elastic, or high-moisture-content samples. The unit complies with general mechanical safety requirements per ANSI B11.1 (American National Standard for Mechanical Power Presses) and meets CE machinery directive essential health and safety requirements when installed with appropriate guarding and interlocked access controls. While not certified as GLP/GMP-compliant out-of-the-box, its construction—using non-reactive, cleanable surfaces and absence of lubricant contact with the crushing chamber—supports validation for regulated sample prep workflows under ISO/IEC 17025-accredited laboratories.
Software & Data Management
This mechanical jaw crusher operates without embedded firmware or digital control interfaces. All operational parameters—including feed rate, dwell time, and discharge setting—are manually configured and documented per SOP. For traceability in regulated environments, users may integrate the crusher into broader LIMS or ELN ecosystems via external process logging: timestamped adjustment records, maintenance logs (e.g., jaw replacement intervals), and batch-specific crush parameters can be captured and archived in accordance with FDA 21 CFR Part 11 requirements using validated third-party documentation platforms. Optional vibration monitoring sensors (not included) may be retrofitted for predictive maintenance trending.
Applications
- Primary size reduction of geological core samples prior to pulverization and geochemical analysis.
- Pre-crushing of cement clinker and limestone for fineness testing (ASTM C114, EN 196-6).
- Sample homogenization in metallurgical assay labs preparing feed for fusion bead preparation (ISO 12620).
- Routine reduction of recycled construction debris for particle size distribution studies (ASTM D6913).
- Controlled fragmentation of ceramic green bodies during R&D prototyping cycles.
- Feed preparation for subsequent grinding stages in mineral processing pilot plants.
FAQ
What is the maximum feed size capacity for the 010A-019 model?
The maximum feed opening is 2¼” × 3½” (57 mm × 89 mm), with a recommended top-size limit of 1¼” (31.75 mm) for optimal throughput and jaw longevity.
Can this crusher be used for wet or sticky materials?
No—this unit is strictly intended for dry, free-flowing feed. Moisture content exceeding 5% or cohesive materials risk bridging, reduced throughput, and accelerated wear.
Is jaw alignment calibration required after replacement?
Yes. Each jaw set includes factory-specified clearance tolerances; post-installation verification of parallelism and gap uniformity using feeler gauges is mandatory per M/B’s Operation & Maintenance Manual.
Does the unit include overload protection?
Standard configuration includes thermal-overload protection in the TEFC motor circuit; optional electronic current-limiting starters or torque-sensing drives may be specified for high-cycle applications.
What maintenance intervals are recommended for bronze bearing inserts?
Under typical lab use (≤2 hrs/day), inspect bushings every 500 operating hours; replace when radial clearance exceeds 0.004″ (0.10 mm) as measured with dial indicator.
