Thank you for visiting us at Wake Stone Corporation. 

Welcome to our education center. Please tour this site to get a better understanding of our company and what we do. Crushed stone is the foundation of our nation. This basic resource is essential for building houses, schools and hospitals. The American crushed stone industry supplies construction materials critical in building and maintaining airports, railroads and the world's safest and most efficient highway system. (Pictured above are Wake Stone employees in the center from left: Seth Miedema, David Lee, Johnny Bratton, and Jared Miedema with students from Ravenscroft School from the class of 2011.

Imagine the difference in your quality of life without — highways, paint, plastics, medicines, glass, driveways, concrete sidewalks, bridges, wallboard, vinyl, brick and stone buildings, homes, concrete block, roofing tile, asphalt shingles, minerals for agriculture — all made possible with crushed stone or minerals from crushed stone. For more interesting facts about our industry, visit our facts page.

Our tour begins at drilling; however, there are many planning and working stages we must go through before reaching this point. A few of which are:

  • Our company geologist, David Lee, conducts geological surveys to test the availability of rock.
  • We also need to obtain the necessary permits from local, county, state and federal agencies.
  • Removal of the "overburden" (soil) to uncover the rock.
  • Building of the primary and secondary plants.

Drilling and Blasting

Drills are used to drill blast holes in the rock.  After these holes have been drilled they are filled with explosive material which includes ammonium nitrate. The blast fragments the rock into sizes small enough to load and haul to the primary crusher.

Wake Stone uses modern explosives and blasting technology to start the first step in producing stone products with a unique in-house approach which focuses on safety, the environment and efficiency. Each bore hole is electronically detonated to produce a well controlled blast.

Hauling

After the blast, shovels and loaders begin there job. Here, a shovel takes this newly broken rock from the "muck pile" and loads it into pit haul trucks.

Crushing and Conveying

The rock is dumped into the primary crusher. Primary crushers are designed to crush large pieces of rock 1 to 4 feet in diameter into pieces approximately 5 to 6 inches in diameter.

Most plants make 5-6 products simultaneously. Larger plants can produce 800,000+ tons of stone per year and have third and fourth crushing stations.

Stockpiling

Loading and Weighing

Ticketing

The customer picks up a scale ticket from the weighmaster and is on the way to the jobsite. The average length of time the customer is in the plant picking up a load of crushed stone, weighing and ticketing is 6 minutes!
