Jaw Crusher Demonstrations: Test With Your Own Rock and Ore
Buyers should require a jaw crusher demonstration using their own rock or ore, and compare feed size, discharge setting, and capacity against the catalog reference values before acceptance.
Ask the supplier to demonstrate the jaw crusher on a representative sample of your own rock or ore, not on a convenient stock feed. A machine with a 950 × 1,250 mm feed opening and a maximum feed size of 800 mm may look suitable on paper, but only your material shows how it breaks, how much fines it makes, and whether it feeds steadily.
In the request for quotation, specify the sample mass, its size distribution, and the discharge setting you need within the 125–250 mm range. Ask which setting the demonstration will use and how throughput will be measured against the 280–760 t/h reference range. During the demonstration, check for bridging at the feed opening, slabby or elongated pieces, and whether the product meets your downstream size requirement. For an acceptance test, agree on the sample, the setting, the measurement method, and the acceptance criteria in advance.
Before requesting a quote, confirm with the supplier that the demonstration will use your material, which discharge setting applies, how capacity will be verified, and what sample quantity is needed.
