Disc Crusher XN-PM-200 Series

Name: Disc Crusher XN-PM-200 Series

Equipment Type: Benchtop Disc-Mill Crusher for Sample Pre-Grinding

Product Code: XN-PM-200

Brand: Xnergy

Product Introduction:

XN-PM-200 Series Disc Crusher is a benchtop disc-mill crusher designed for pre-grinding coarse feed materials — ores, sintered chunks, ceramic blocks, dried battery slurries, and agglomerated powders — from feed sizes up to 20 mm down to discharge particle sizes of approximately 100 μm – 0.5 mm in a single pass. Two counter-rotating hardened-steel grinding discs apply continuous shear and compression to the feed, with the disc gap continuously adjustable via digital display for repeatable discharge sizing. The crusher integrates a dust-exhaust interface to prevent powder contamination of the work environment, and a steel displacement platform that extends service life by approximately 30% versus conventional disc-mill designs. Three configurations are available (XN-PM-200S, XN-PM-200Y, XN-PM-200T) for different wear-part and disc-material requirements.

Key Features:

Hardened-steel grinding discs with long service life
Multiple disc materials available on request
Large feed size — up to 20 mm input
Continuously adjustable disc gap with digital display for repeatable discharge sizing
Discharge particle size approximately 100 μm – 0.5 mm in a single pass
Dust-exhaust port — prevents powder pollution of the work environment
Steel displacement platform — approximately 30% longer service life than conventional disc-mill designs
Three-phase 1.5 kW motor (380 V / 50 Hz)
Easy to operate, clean, and maintain
High sample-processing efficiency — very small discharge size achieved in a short time
Three model configurations (S / Y / T) for different wear-part requirements

Series Specifications:

The three configurations share the same drive, dimensions, and process parameters but differ in disc and wear-part build (reflected in the weight difference). Please confirm the appropriate model with sales based on target feed material and disc-material requirements.

Application Areas:

XN-PM-200 Series is suitable for:

Pre-grinding ores, mineral samples, and sintered chunks before fine grinding
Pre-crushing dried battery materials, agglomerates, and powder cakes before nano-grinding
Sample preparation for XRF, XRD, and chemical analysis where the feed material is too coarse for direct fine milling
Reducing ceramic, glass, and brittle composite materials to manageable particle sizes
Laboratory and pilot-scale workflows that need a pre-mill stage upstream of planetary ball mills
Battery R&D — breaking up calcined cathode precursors or recycled electrode powder cakes before fine processing

Maintenance:

Clean the discs and crushing chamber regularly with a brush or compressed air
Lubricate moving parts periodically to ensure smooth operation
If the equipment is not used for an extended period, clean the disc surfaces and apply a protective anti-rust coating
Periodically inspect screws, nuts, pins, and other fasteners to prevent loosening
Inspect disc wear regularly and replace at end of life to maintain discharge size specification
Verify dust-exhaust connection is clear and the collection system is operating before each run

Safety Notes:

Do not place hands or other body parts in the feed hopper or near the rotating discs during operation
Do not feed metal foreign objects (bolts, tools, fragments) into the hopper — disc damage is unrecoverable
Operation should be performed by a single trained operator
Disassembly should only be performed by qualified technicians
Verify three-phase 380 V electrical installation and floor placement before commissioning
Always connect to a dust-collection system or local exhaust ventilation before crushing — uncontrolled dust release is both an environmental and an inhalation hazard

Specifications are provided for reference and may be adjusted to suit specific process requirements. Disc materials and wear-part configurations are specified at order time.

Note: Specifications listed above are typical and for reference only. Actual crushing performance depends on the input material hardness, feed size, moisture content, and operating parameters. XN-PM-200 Series occupies a specific position in Xnergy’s milling line — it is the only disc-mill crusher and is positioned upstream of all the planetary ball mills, not as an alternative to them. Where a planetary ball mill is asked to reduce 5 mm sintered chunks to nano-scale fineness, most of the operating time is spent on the coarse-to-medium reduction stage — work that XN-PM-200 does in a single pass at much higher throughput. The natural workflow is: feed material (≤20 mm) → XN-PM-200 disc crush to ~100 μm – 0.5 mm → planetary ball mill nano-grinding to the target final fineness. For the planetary fine-grinding step downstream, choose the appropriate model based on application: general-purpose XN-YXQM Series for ambient grinding, XN-MAX1600 for mechanical alloying and rapid sub-micron grinding, XN-XH-XQM for room-temperature heat-sensitive materials (1 – 30 °C), XN-YD-XQM for cryogenic grinding (−60 to −1 °C), or XN-QM-QX when dead-zone-free 360° mixing matters.
