How should feed and discharge particle sizes be specified in a commercial food pulverizer contract?

Specify maximum feed size, target discharge distribution or screen size, and allowable oversize percentage in the contract. If this machine feeds another process, confirm the interface dimensions, transfer rate, and upstream or downstream cycle time. Where accuracy matters, use repeated samples rather than approving the machine from a single successful piece. The final report should identify the machine configuration, test date, material used, operator conditions, and measured result. The final acceptance record should identify the tested recipe, machine settings, instruments, operator conditions, and measured output.
