Automatic XRF Pellet Press for Laboratory Spectrometry Sample Preparation

Product Overview

This automatic laboratory sample preparation system is a highly advanced, PLC-controlled hydraulic pressing solution designed to produce top-tier pellet samples for X-ray fluorescence (XRF) and infrared (FTIR) spectroscopy. Emphasizing automated operation, high-precision pressure management, and robust construction, the equipment streamlines sample preparation by eliminating manual operator errors and delivering consistent density profiles across all processed samples. This unit replaces manual mechanical effort with a precise, digitally governed hydraulic press cycle, ensuring flawless reproducibility for quantitative elemental analysis.

The primary use cases for this equipment span a wide range of industries including cement production, mining, metallurgy, geological surveying, battery research, pharmaceutical compounding, and materials science. It is highly optimized for pressing powdered materials with or without binding agents into perfectly flat, uniform discs. The system accommodates various sample containment options, including boric acid cups, steel rings, aluminum cups, and plastic outer rings, which allows laboratories to easily adapt the press to their specific testing standards and downstream analytical equipment.

Built for long-term operational reliability under continuous, high-volume production cycles, this system features structural elements crafted from high-strength alloy steel that undergoes rigorous thermal tempering. Relying on premium integrated hydraulic components, an intelligent electronic control system, and a comprehensive suite of safety protections, the equipment provides laboratory managers and quality inspectors with absolute confidence in its durability. Whether deployed in an active production-line laboratory or a high-end research institution, this system maintains high stability and precise force delivery under the most demanding analytical conditions.

Key Features

• Intelligent PLC and Touch-Screen Interface: Equipped with an industrial-grade PLC system and a high-resolution color HMI screen supporting bilingual operation (Chinese and English). This terminal allows technicians to easily configure target force, dwell time, and release speed, establishing standardized, operator-independent sample prep protocols.
• Controlled Multi-Stage Pressure Relief System: Features an optimized slow-decompression sequence that prevents sample cracking, blistering, or splitting during the release of high tonnage. This micro-adjustable valve technology gently vents cylinder pressure, significantly improving the pelletizing success rate of fragile mineral and chemical powders.
• High-Performance Integrated Hydraulics: Utilizes premium, imported hydraulic valves and high-grade L-HM46 wear-resistant hydraulic oil. A built-in high-density filtration circuit blocks particulate contaminants, protecting internal control valves and ensuring extremely stable, repeatable force application over thousands of cycles.
• Automated Piston Return and Cycle Efficiency: Designed with a high-speed automatic piston return system that eliminates manual mechanical resetting between cycles. Real-time piston status, stroke displacement, and actual force metrics are updated continuously on the screen, maximizing batch efficiency.
• Heavy-Duty Structural Metallurgy: Core load-bearing elements, including the dual vertical columns and the heavy-duty swing-arm crossbeam, are machined from high-strength alloy steel that undergoes rigorous thermal tempering, ensuring zero structural deformation under repeated 60-ton loads.
• Universal Mold Configuration and Software Optimization: Fully compatible with multiple analytical ring and cup options, including boric acid cups, aluminum cups, steel rings, and plastic outer rings. The control interface features dedicated software profiles optimized to distribute pressure evenly based on the chosen containment media.
• Industrial-Grade Sealed Operator Console: The entire touch control panel is protected behind a heavy-duty, chemically resistant membrane seal. This prevents abrasive mineral powders, cement dust, or chemical reactants from infiltrating the electronics while enabling simple wipe-down maintenance.
• Integrated Tool Management Compartment: Features a designated bottom-mounted utility cabin built directly into the frame. This functional design neatly accommodates essential sample preparation accessories, including boric acid dispensers, powder levelers, funnels, and cleaning brushes, saving valuable laboratory bench space.

Boric Acid Mold Standard Operating Procedure (SOP)

1. Piston Initialization: Access the touchscreen controls to drop the piston to the loading position. Align the dedicated boric acid funnel with the top of the mold core.
2. Sample Loading: Dispense approximately 5 grams of target sample powder into the center cavity, ensuring even distribution across the bottom.
3. Powder Flattening: Use the specialized powder flattening tool to gently level the sample powder, avoiding excessive downward pressure.
4. Boric Acid Backing Application: Slowly pour high-purity boric acid powder into the outer funnel channel until it completely envelopes the target sample.
5. Clean Excess Powder: Use the specialized lab brush to sweep any stray boric acid particles down into the mold cavity.
6. Cavity Capacity Check: Ensure the combined height of the sample and backing material matches the volumetric capacity of the mold sleeve.
7. Mold Loading: Position the assembled mold onto the center platform and swing the crossbeam into its locked position.
8. Lead Screw Adjustment: Rotate the upper lead screw handle until the distance between the mold top and the pressing head is within 0.5 to 1.0 mm.
9. Parameter Setting and Pressing: Set target tonnage (up to 60T) and dwell time on the touchscreen, then press the green 'Start' button to execute.
10. Demolding and Extraction: Once the press completes the automatic slow decompression cycle, press the 'Demold' button, retrieve the mold, and extract the finished pellet.
