Dry Batch Plants

What is a dry batch plant?

A dry batch plant weighs aggregate, sand and cement and dispenses them — still dry — into a mixer truck. The truck adds the mixing on the drive to the pour. So the plant is a weighing and loading machine, not a mixing machine.

That sounds like a limitation until you notice it is usually the right answer. If you already run mixer trucks, the truck is your mixer. Buying a central mixer you do not need adds cost to the purchase and a wearing part to maintain, and it slows the plant down, because a wet plant can only discharge as fast as it can mix. A dry plant does one job: it loads a truck accurately and gets it moving.

Throughput is the whole point

On a dry plant the number that decides everything is aggregate storage, because storage is what determines how many trucks you can load before a loader has to stop and refill the bins. These plants run from 5+ up to 36+ cubic yards, with three aggregate bins of 12 yards each on the largest.

• 5–8 cu yd — a small yard or a single truck. The loader keeps up easily.
• 12–16 cu yd — steady work. You stop feeding the plant every cycle.
• 24–36+ cu yd — a multi-truck operation. At this size the plant stops being the constraint and the trucks become the constraint, which is exactly where you want to be.

The trap is buying storage for the average day instead of the busy one. A plant that keeps up comfortably in February and holds your trucks in a queue in July has cost you the whole summer. Size it for the days that pay.

Dry or wet? Choose by what you already own

This is the only real decision, and it is not close once you frame it properly:

• You run mixer trucks — buy dry. The mixing capacity is already parked in your yard; a wet plant would duplicate it.
• You need finished concrete at the point of use and have no trucks — buy wet. A dry plant would produce nothing usable without a truck to mix in.
• You are supplying a ready-mix market — dry plant plus trucks is the conventional model, and it is conventional because it works: the truck mixes during the haul you were making anyway, so the mixing is free time.

A dry plant also pairs naturally with a portable cement silo, since bulk cement is what makes the economics of batching your own work at all.

Financing a dry batch plant

Concrete equipment is a textbook financing case: it is a hard asset that holds its value, so the machine carries much of the credit decision itself rather than resting entirely on your balance sheet. That is what puts it in reach of a growing contractor and not only the biggest yards. Terms are normally structured to the life of the equipment, so the payment sits against the work it wins you. Mix Right sells through quotes rather than a published price list, so get the quote for the exact configuration you want, then use the estimator above to see what that becomes as a monthly payment. Approvals commonly come back in about 24 hours.
