How should lift height and product breakage be evaluated together on a commercial bucket elevator?

Verify lifting height and speed while observing drop impact, product breakage, and residual material in the buckets. Before comparing suppliers, fix the product specification, target throughput, and operating condition used for the test. During FAT, use calibrated instruments where relevant and keep the original readings with the acceptance record. The purchase specification should state the method, tolerance, sample quantity, and treatment of nonconforming results. Also confirm cleaning access, routine maintenance points, and the parts that operators must remove between production runs during normal operation.
