HTLX-1 Coal drop strength tester is used to determine the crushing resistance of industrial briquettes. The product is designed and manufactured in accordance with the coal industry standard MT/T 925-2004 “Test Method for Shatter Strength of Industrial Briquettes” and references the national standard GB/T 15459-1995 “Test Method for Shatter Strength of Coal.”

Sampling and Preparation

• Collect briquette samples as per MT/T 915.
• Use the long-band method to reduce the sample to 6 kg, ensuring at least 60 briquettes are intact and crack-free.
• Air-dry the samples and discard any damaged or cracked briquettes.
• Divide the remaining sample into 10 equal sections, randomly selecting 1 briquette from each to form a 10-briquette test group. Repeat to prepare a second group.

Testing Procedure

1. Weigh a test group (accuracy: ±1 g).
2. Drop each briquette from a 2-meter height onto a steel plate.
3. Screen the fragments after each drop, retaining pieces >13 mm.
4. Repeat the drop-and-screen process 3 times, cleaning the plate between drops.
5. Weigh the remaining >13 mm fragments after the third drop (accuracy: ±1 g).
6. Calculate the shatter strength using the standard formula.
