Two machines with the same basic job can cost different amounts because of capacity, configuration, condition and what comes with the quote. Start by asking both dealers to price the same job: the material you are processing, the size coming in, the product you need and the production rate you are targeting.
Look at the equipment and what comes with it. Compare the size and configuration, tracked or portable versus stationary setup, controls and any required conveyors, screens or other equipment. For a used unit, ask about hours, condition, maintenance history and included attachments. Check whether freight, setup, startup support or training are included or priced separately.
Compare the cost to run it. Ask about wear parts, energy or fuel, routine service, and what it takes to service the equipment on your site. Compare estimated cost over the same period and expected tons of finished product. If there are unknowns, ask each dealer to list their assumptions so you can compare the quotes on the same basis.
What to send for a quote: Feed material, maximum feed size, required product sizes, target tons per hour, site location, expected schedule and whether the machine will move between jobs. For an existing plant, include a layout or the models of the equipment it will work with.
