  1. Material characteristics：

  • Particle size: For large particles (e.g., >100mm), a large opening sampler head and a powerful crusher must be selected.

  • Humidity: High humidity materials require anti-blockage design (e.g., increase the slope of the chute, add vibration devices).

  • Belt Specifications：

    • Width: The sampling head must cover the full width of the belt (e.g., if the belt width is 1200mm, the sampling head width ≥ 1300mm).

    • Inclination: Generally ≤15°; for high inclination scenarios, a special anti-sample-slip structure design is required.

  • Detection Accuracy：

    • High precision requirements (e.g., calorific value error ≤ ±1%) necessitate an increased number of sampling instances (recommendation: ≥30 times/batch) or a multi-level sub-sampling configuration.

  • Compliance：

    • Export projects must comply with ISO, ASTM standards, and domestic projects must meet GB/T 19494, GB 50074, and other specifications.
