Mobile crushing spread with jaw, cone, screen and stackers running on site

Custom & mobile crushing

Turn the cut
into the base.

The material already on your site is usually the cheapest material on your site. We bring the plant to it — or crush it at our pit and stage it against your draw.

Why crush on site

Hauling waste rock off a job and hauling aggregate back on is two truck movements and two invoices for the same cubic yard.

Most jobsites generate oversized and excess material that needs to be hauled off. Crushing it in place removes the dump costs, the import cost, and the truck traffic through a live jobsite — and on a tight schedule, it removes a dependency on someone else’s delivery calendar.

We run to published specs or to a gradation you write. Over 500,000 tons crushed year to date, on our ground and on other people’s.

Two ways we do it

On your site,
or from ours

Mobile — plant comes to you

We mobilize the spread to your site and run it where the material sits. Setups are sized to the job, from a single spread on a subdivision to a full train on a long-running commercial site.

This is the right answer when there’s enough material to justify the move and the site has room to work and stockpile. Weber Basin Water District is a recent example — forty thousand tons crushed in their own South Weber pit with jaw, cone, screen and stackers running together.

Once a spread is set, it runs. Production starts at first light and the stockpiles build through the day, so the material is there when the grade is ready for it.

Crush, haul & stage

Not every job wants a plant on it. Some sites have no room, some schedules can’t absorb the disruption, and some contractors would rather draw material as they need it than manage a stockpile.

For those, we crush at our own pit, haul, and hold the material against your draw — produced, sized and waiting before you need it instead of chased once you do. Ames Construction runs this way with us on a multi-year agreement through 2028.

The plant

What runs
in the train

A full spread is four jobs happening in sequence. Which pieces come out depends on what you need off the far end.

StageEquipmentWhat it does

SecondaryCone crusherShapes the product and tightens gradation — the difference between spec material and rock that merely got smaller

Concrete with rebar is routine — steel is separated during processing. Contaminated or hazardous material is not something we handle; that needs a specializt.

How a job runs

Start to
stockpile

01

Site review & spec

We walk the site, look at what the material actually is, and confirm the gradations you need off the far end. Access, working room and stockpile space get sorted here rather than on mobilization day.

02

Mobilize & set up

Plant is moved in and set. Dust suppression, water and any county requirements for the site are handled as part of the setup — requirements vary by location and we’ll tell you what a given site needs.

03

Production

The spread runs to spec. Output is screened and stockpiled separately by product so material is ready to load rather than needing rework.

04

Report & demobilize

You get production figures for what was actually made, then the plant comes off and the site goes back to work.

Common questions

Contract crushing

How much material justifies bringing a plant to my site?

As a rule of thumb, around 15,000 tons and up is where mobilizing a plant usually starts to make the most sense. That figure can come down considerably depending on haul distance and dump costs — a site a long way from a pit justifies crushing at a much smaller volume than one next door to one.

Send us the quantity and location and we’ll tell you straight whether mobilizing is worth it or whether you’re better off buying material delivered.

Can you hit a specific gradation?

Yes. We run to published specifications or to a gradation you write. The cone in the train is what makes tight gradation control possible — a jaw alone reduces size but gives you far less say over the shape and distribution of what comes out.

What about dust, noise and permitting?

Dust suppression is part of every setup. Beyond that, permitting and operating requirements vary by county and by site — every job is different — so we work out exactly what applies to your location during the site review rather than promising a blanket answer.

Can you crush concrete with rebar in it?

Yes, that’s routine. Steel is separated during processing. What we can’t take is contaminated or hazardous material — that needs a specializt contractor.

Do you provide testing on the finished product?

Yes. We provide third-party tested gradations on the finished product, so what you’re accepting has been verified by an independent lab rather than taken on our word.

How fast does the plant run?

Production rate depends on the feed material, the spec you’re after, and how the site is set up to keep the plant fed. We’ll give you a realistic rate for your specific job rather than a headline figure that assumes perfect conditions.
