Factory Acceptance Checks for a Jaw Crusher
Define pass or fail checks for a jaw crusher FAT using the stated feed opening, feed size, discharge range and capacity range as reference values, not guarantees for a supplied unit.
A buyer specifying a jaw crusher with a 950 × 1,250 mm feed opening should decide up front which checks must pass before shipment and which are only recorded. That decision shapes the request for quotation and the acceptance test.
Ask the supplier to state the test material and how it relates to your rock or ore. Will the demonstration use a feed no larger than 800 mm, and how will oversize be excluded? For the discharge opening range of 125–250 mm, agree on the settings to be tested and how the gap is measured. For capacity, the reference range of 280–760 t/h should be treated as catalog information; ask what throughput the supplier will demonstrate, with what material and method, and whether results are guaranteed or indicative.
Make pass or fail binary: for example, the crusher runs at agreed settings without abnormal vibration, and measured discharge gaps match the set values within a tolerance you define. Record capacity rather than promising a figure.
Before requesting a quote, confirm with the supplier which checks they will witness, the test material and measurement methods, the tolerances offered, and what documentation accompanies the factory acceptance test.
