Nathan Pivoted from Big to Compact to Grow His Concrete Recycling Business.

Case Study

As Natural Resources are Getting Depleted Nathan is Finding More and More Success with his Concrete Recycling Business.

Flatrate Inc is a concrete pumping, trucking, and concrete recycling business out of Big Stone City, SD. Nathan's family used to be in the ready mix concrete business and Nathan found the need to crush the concrete demo piles that people have buried over the years. For years, it was difficult to recycle concrete because virgin aggregates were so much cheaper. This picture changes as quarries and gravel pits are getting depleted and material has to be hauled a long distance.

It All Started With the Rental of a Big Portable Impactor

The rental revealed that there was a market for a concrete recycling business centered around a tracked impact crusher. As he rented the crusher it started snowballing and people started calling for quotes.


No Room for a Big Impactor?
Concrete Piles are not Stockpiled in the Most Convenient Locations.

When Nathan operated a big portable impact crushers he needed a lot of real estate to set up a crushing operation. Usually, you work in a landfill or confined yard and there is simply not enough room. By the time you get a portable jaw crusher and an impactor there is no room and you have to move the pile a long distance to a wide open space.

A Small Footprint Makes it Easier to Set Up your Crushing Operation

A mobile concrete recycling business has many moving parts. A primary jaw crusher, an impact crusher, screening plants, and stacking conveyors. Often it is easier to set up a single compact impact crusher than a full crushing spread. Therefore, Nathan pivoted from a big impactor to a compact impact crusher so that he becomes more agile and get to the jobs quickly and easily.

Big portable crushing plants would require multiple moves and the setup of transfer and stockpiling conveyors which takes not a few minutes but hours.


Nathan Has Grown his Concrete Recycling Business with a RM 120X Mobile Impactor

To be clear, the RM 120X Mobile Impactor is a compact machine but in the "same class" as many portable crushers. It features a 44" x 36" inlet opening and has a top capacity of up to 385 TPH (depending on the material). The beauty of the compact size is that you can move it on standard trailers and get to a lot of the smaller job sites.
