Laboratory Roll Crusher for Mineral Sample Preparation, 1–3 mm Output

The laboratory roll crusher is engineered for crushing medium-hard and brittle materials into a controlled particle size for mineral sample preparation. Two counter-rotating rolls reduce material through compression and shear, delivering consistent, reproducible results for laboratory workflows.

With a maximum feed size of 13 mm or 26 mm depending on the model, and a listed discharge size of 1–3 mm, this laboratory roller crusher suits mining laboratories, mineral processing facilities, and metallurgical testing applications. A range of roll diameters, roll widths, and roll materials is available to meet different sample preparation requirements.

• Controlled Discharge Size: Adjustable roll clearance helps control the final particle size. The listed discharge range is 1–3 mm; actual results depend on material properties and operating conditions.
• Multiple Roll Configurations: Available roll sizes include Ø200 × 75 mm, Ø200 × 150 mm, Ø250 × 75 mm, Ø250 × 150 mm, and Ø300 × 300 mm.
• Roll Material Options: Manganese steel and chromium steel options support different wear and material requirements.
• Optional Tungsten Carbide-Coated Rolls: Available for suitable hard or abrasive materials, subject to application assessment.
• Timed Start/Stop Control: Supports convenient operation during routine laboratory sample preparation.

* Listed capacity is indicative and varies with material properties and operating conditions.

This laboratory roll crusher is suitable for:

• Mineral sample preparation before laboratory testing
• Ore crushing in mining and metallurgical laboratories
• Geological sample preparation
• Crushing suitable materials in building materials and related industries

When choosing a model, consider the following factors:

• Feed size: Confirm the maximum size of the material entering the crusher.
• Target particle size: Check whether the required discharge size is achievable for your material.
• Throughput: Estimate the quantity of material to be processed per hour.
• Roll material: Select manganese steel, chromium steel, or an appropriate optional coating based on wear and contamination requirements.
