Sell Your Aggregate Equipment

MachineryBarn buys used aggregate equipment — jaw and cone crushers, impactors, screening plants, conveyors, washing plants and pugmills, portable and stationary. Aggregate plant is valued on the wear parts and the drive: liners, jaws, mantles and screen media are consumables that can represent a serious cost on their own, and bearing and gearbox condition determines whether the machine is a running plant or a rebuild. Whether the unit is portable also matters enormously, because it decides who can practically buy it.

Aggregate Equipment we buy

Configuration changes who the next buyer is, so it changes the offer. These are the variants worth naming when you describe your machine.

Jaw crusher

Primary reduction by compression. Simple, robust, and the most common first stage. Priced heavily on jaw plate and bearing condition.

Cone crusher

Secondary and tertiary reduction. Mantle and bowl liner wear, plus the hydraulic adjustment system, decide the value.

Impact crusher

Reduction by striking. Favoured for recycled concrete and asphalt. Blow bar and apron condition are the consumables.

Screening plant

Separates by size on vibrating decks. Screen media, bearings and the vibrator mechanism carry the value.

Conveyors, wash plants and pugmills

Supporting equipment that is frequently sold alongside a crushing or screening spread and is easier to place as part of one.

What determines a used aggregate equipment's value

Roughly in order of how much each one moves the number.

1. 1

   Wear part condition

   Jaw plates, cone mantles and bowl liners, impactor blow bars and aprons, and screen media are all consumables with substantial replacement costs. A crusher needing a full set of liners is priced very differently from one recently relined, and this is usually the largest single variable.

   How to check it: Measure remaining thickness on jaw plates and liners where you can, check blow bar wear, and look at screen media for holes and worn cloth.

2. 2

   Bearing and drive condition

   The expensive failure. Main shaft bearings on a jaw, the countershaft and head assembly on a cone, and screen vibrator bearings are all major-component repairs. Noise and heat are the available signals.

   How to check it: Run the plant if possible and listen for rumble, knock or unusual vibration. Check bearing housings for heat and grease condition.

3. 3

   Portability

   Track-mounted and wheeled portable plants have a much broader buyer pool than stationary installations, because a portable plant can move to the next job while a stationary one has to be dismantled, transported and re-erected. This changes the number substantially.

4. 4

   Frame and structural condition

   Screening plants and crushers vibrate constantly and the frames crack. Prior weld repair is normal; the question is whether it was done properly and where. Structural cracking near the vibrator mounts or crusher frame is serious.

5. 5

   Engine or power unit

   Portable plants have their own diesel power units subject to the same California off-road diesel considerations as any other equipment. Electric plants need to match the buyer's available supply, which is its own constraint.

6. 6

   Hydraulic and control systems

   Cone adjustment systems, tramp release, hydraulic folding on portable plants and the control panel all need to work. A cone that cannot be adjusted cannot produce to spec.

7. 7

   Conveyor and belt condition

   Belts, idlers, pulleys and lagging are constant wear items across every conveyor in a spread, and a plant with worn belts throughout represents a meaningful bill.

8. 8

   Completeness of the spread

   A matched crushing and screening spread with its conveyors and feeders is worth more together than as separate machines, because the buyer gets a working production line rather than a compatibility exercise.

What gets inspected on an aggregate equipment

Knowing what a buyer looks at lets you describe the machine accurately the first time, which avoids the offer changing later.

What we need to price your aggregate equipment

You do not need all of it to start. The more of it you have, the closer the first number is to the final one.

• Make, model and serial number of each unit
• Year and hour meter reading where fitted
• Equipment type — jaw, cone, impactor, screen, conveyor, wash plant
• Portable on tracks or wheels, or stationary
• Wear part condition, and when liners or media were last replaced
• What material it processed — granite, river gravel, recycled concrete, asphalt
• Whether it runs and produces to spec
• Power source — diesel power unit or electric
• Whether the units form a matched spread
• Where it sits and what the access is like

Makes and model families we see most

We buy aggregate equipment from manufacturers beyond this list. These are the ones that come up most often, with the series a seller is likely to recognise from the machine.
