Wasted time. Wasted energy. Wasteful spending. Regardless of industry, waste is one of the most detrimental and costly factors to a business. One New Mexico-based construction company was able to turn what used to be tons of waste into big profit with the help of a single crushing machine.

The construction company Ramirez & Sons Inc. purchased a new crusher less than a year ago, and already has seen results through increased production and product offerings, which have led to a growth in customer base and profits.

Looking to Grow
Ramirez & Sons is a family-owned company, formed in 1982. The company is built on generations of industry experience dating back to the 1920s. Now led by fourth-generation professional contractor Alonzo Ramirez Jr., Ramirez & Sons is the second largest paving and aggregate provider in southeastern New Mexico and employs more than 65 professionals at its corporate office in Hobbs, N.M.

Ramirez & Sons began as a general earthwork and construction company, serving a client base of both municipal and private contractors in Hobbs and Lovington, N.M., and surrounding areas. Today, the company offers general excavation, site prep, highway paving and both water and sewer utility work.

In 2010, the company enhanced its capabilities even further with the addition of its first hot-mix asphalt plant. In addition to contracting services, Ramirez & Sons also sells material for use in hot-mix asphalt, building pads and as base layers for road building. This side of the business is led by Ken Smith, plant manager and crushing/hot mix superintendent.

“Historically, the company has been primarily involved in asphalt recycling,” he says. According to Smith, Ramirez & Sons had previously produced four different size materials: three-quarter inch; three-eighths inch; fines; and base course. The company both sold the material and used it in its hot-mix plant for its own paving work.

While asphalt recycling has certainly brought value to the company, Smith felt he could be offering more material for sale and that substantial money was being left on the table.

“We were wasting a lot of material,” says Smith, a newer member of the Ramirez & Sons team. Because the company was only recycling asphalt, it was missing out on other saleable materials, particularly concrete.

Recycled concrete and other aggregates can be utilized in many applications, and being able to provide high-quality material would potentially bring new customers to Ramirez & Sons. That’s not all. Smith figured the company would be able to use the material in its own operation, cutting time and costs associated with outside material purchasing.

While the benefits were clear, Ramirez & Sons simply wasn’t in a position to make a move; the company’s crusher wasn’t suitable for processing concrete. Without the right crusher, the company lacked the versatility needed to enter into full concrete and aggregate processing services.

Hand in hand with that, Smith also noted that production rates weren’t as high as he felt they could be, coming in at a daily rate of roughly 120 tons per hour (tph). The equipment should have been producing more but had experienced a lot of issues with breakdowns and excessive downtime, according to Smith. End-product quality wasn’t up to par either, and a lot of potentially usable material was being left as waste. That all changed when Smith met with Ramirez & Sons’ longtime equipment dealer, Warren Cat, to explore new machines that could amp up production and allow the company to offer larger amounts of more saleable material.

The Solution

Warren Cat is one of the largest and fastest-growing Caterpillar dealerships in North America. The company operates more than 16 locations in Oklahoma and west Texas, offering new, used and rental equipment. Throughout his years in the industry, Smith always worked with Warren Cat for equipment needs as well as parts and service. Warren Cat was already Ramirez & Sons’ exclusive dealer, so there was no question about whom Smith would call when he set out to find a new machine.

Brian Hutchinson, Ramirez & Sons’ contact at Warren Cat, spoke with Smith to find out exactly what he was looking for in a new crusher. First, Hutchinson gained insight into Smith’s pain points with his existing crusher—primarily, lagging production and excessive downtime. Next, the two discussed Smith’s goals and expectations of the new machine—greater output, more processing capabilities and high uptime. After learning both, Hutchinson felt he had the solution—an Irock crusher.

Hutchinson knew of one that was available at one of Warren’s sister locations in Odessa, Texas. The particular unit, Irock’s RDS-15, was a four-bar impactor, three-stage mobile crusher that could process a variety of materials, including concrete and other aggregates, at tonnage rates that could double Smith’s hourly output. It sounded like a great fit for Ramirez & Sons, so Hutchinson put Smith in touch with Bill Reiner at Warren Cat’s Odessa location. Smith made the trip south to take a look at the machine. About 175 miles and a few days later, Smith says, “It was sitting in our yard.”

Though Smith was confident the RDS-15 was the solution to the company’s low production rates, Ramirez & Sons decided first to lease the machine to see how it would stand up to the company’s high standards and demanding production schedule. After just two months the company purchased the machine, cementing its place as the primary crusher in the Ramirez & Sons fleet.

Smith has been operating the RDS-15 for less than a year but already has seen production rates increase from about 120 tph to approximately 300 tph. While that’s more than double, the impact really adds up when looking at the bigger picture. Based on a typical 12-hour day and an average six-day week, tonnage output has gone from 8,640 tons per week to 21,600. The impact continues to grow with each week, month and year, says Smith. In addition to sheer output, the company also has been able to diversify its sales offerings from four products to nearly 15, including various sizes of recycled concrete, aggregates and asphalt.

“The machine has its own double-deck screen,” Smith explains. “I’m able to easily change out the bottom screen, which allows us to produce different sizes we hadn’t been able to with other machines.”

Additionally, the configuration options enable Ramirez & Sons to produce three different materials at once, and the impact aprons are easy to adjust for precise sizing, according to Smith. He says this offers him the versatility and efficiency of producing multiple products at once while ensuring they’re accurately sized for best sale potential.

As Smith expected, Ramirez & Sons’ newfound diversity has opened up a new customer base and more opportunity. Most notable is the oil boom happening in Hobbs and nearby cities. Several oil companies use Ramirez & Sons’ three-quarter-inch-minus material, primarily for parking lots and temporary roads.

“That has been one of the biggest areas of growth for us,” Smith says. “The oil boom here is incredible.”

While increased production rates and profits are both key, Smith says the primary benefit is zero—as in zero waste. “I can honestly say we’re no longer wasting any material,” Smith says. “It’s remarkable.”

Ramirez & Sons now offers a variety of material sizes, from three-eighths-inch minus to five-eighths-inch minus to 1-inch minus. The products are used in a variety of applications, including hot mix, road base, subbase and building pads. The company also produces specialty size material for specific applications. For example, a septic system’s base lines require a larger rock, from 1 to 3 inches in size. Smith says with just one simple adjustment his RDS-15 can produce it quickly and precisely.

Often overshadowed by the high production rates and lack of material waste is the reliability of the crusher. “It seems like you can always remember the times your equipment has failed on you,” Smith explains. “On the flip side, when a machine runs smoothly and doesn’t require attention, it’s easy for it to go unnoticed. Ironically, it’s the machines that do their job and run like they’re supposed to that almost seem like they’re forgotten. But that’s really when you should be taking notice, and I credit the RDS-15 for its reliability.”

Smith’s philosophy is, as long as it’s running, he’s happy. And that’s important to a company that operates up to 12 hours per day, six days per week.

Maintenance requirements have been minimal and have been mostly routine items, such as keeping the machine lubricated, refuels and changing the oil, says Smith. One feature that contributes to this, he says, is Irock’s rock box, an alternative to discharge chutes found on similar units. The rock box uses a shelf system with abrasion-resistant wear bars that allow crushed material to build up and act as a wear liner.

Smith also points out the minimal wear he has seen on the machine citing the blow bars as a prime example. In more than 1,400 hours of operation with the RDS-15, he’s only had to rotate the bars once and expects to get at least 700 or more hours out of them.

“I haven’t yet been able to accurately quantify our maintenance and downtime savings from the RDS-15, but I can tell you both have gone down sharply while production has more than doubled,” Smith says.

All in the Family
The RDS-15 has been a welcome addition to the Ramirez & Sons fleet. In fact, Smith is already leasing a second Irock crusher, an RDS-20. It’s a similar machine, but it offers more screening area and a larger vibrating feeder. Like the RDS-15, Smith’s plan is to purchase the machine soon, and he already has his eye on yet another Irock he’d like to add further down the road.

Most successful company owners will tell you, if you find a great employee, don’t let him or her go. Furthermore, try to bring in more of that same type of person. As evidenced by Ramirez & Sons, the same also can be said about equipment.
