Best in the business for Colorado Materials, Ltd. with Sandvik UJ640E jaw crusher investment

When needing to source a mobile jaw crusher and increase their production capacity, Colorado Materials needed to look no further than Sandvik. With experience of Sandvik equipment in a stationary application, and recommendations as a supplier of one of the best mobile jaws in the industry, Colorado Materials decided to invest in the largest tracked jaw crusher in the Sandvik mobile crushing and screening offering and haven’t looked back since. They say their first mobile unit of this size, Sandvik UJ640E, which they have aptly named “Goliath”, is one of the best they have seen in 35 years of crushing.

Colorado Materials, Ltd. is one of the largest privately held quarries in the United States. Established in 1980, the Hunter, Texas quarry provides millions of tons of materials annually to various locations via truck and rail. In addition to the main quarry, Colorado Materials, Ltd. maintains several locations across Texas, providing ease of delivery to many project locations. As a company, they are committed to providing quality crushed limestone and hot mix asphalt with personalized customer service to their clients throughout the state of Texas.

To process their aggregates, Colorado Materials have been operating Sandvik jaw crushers in a stationary application for a number of years and already familiar with the reliability and performance. When a new project came up to process basalt from a mountain in Texas, it was decided that a mobile unit was the best option to reduce transportation of the material to the crusher. Sandvik was the obvious choice in the selection process and Sandvik Mobiles’ local distributor in Texas, Crushing Tigers, was quickly on hand to determine the best model to suit their application.

Due to the high capacity requirements and need for a reliable machine, the tried and tested UJ640E primary tracked jaw crusher was proposed by Crushing Tigers. The biggest in the Sandvik range of portable plant, the UJ640E features a large 60 x 44” / 1500 x 1100 mm single toggle jaw capable of achieving up to 1,100 stph / 1,000 mtph. The machine is well-proven in hard and abrasive rock applications and seemed the ideal fit for Colorado Materials’ basalt application.

Low operating cost combined with sustainable operation

The UJ640E is electrically powered and offers a low cost-per-ton solution. It comes with an onboard diesel generator & electric plug-in grid supply, so customers can choose the most efficient means to operate. This has environmental benefits reducing not only its fuel consumption but also its carbon footprint and providing cleaner working conditions on site through less operating noise and emissions. In addition, the unit also comes fitted with a dust suppression system as standard to minimize dust emissions and rubber lined impact zones for reduced operating noise.

John Janek, Operations Manager at Colorado Materials, says that they have been impressed with the efficiency of the unit and that the “fuel economy is excellent for a gen-set.”

As well as the benefits of fuel economy, as all onboard components are electrically driven. This improves the reliability of the unit and reduces overall maintenance required.

No stone is going to knock this Goliath down

John says he cannot fault the reliability since commissioning the machine. “Reliability has been excellent and production rates as expected for the reduction required.”

They are currently reducing to 6” / 150mm minus with a feed size of 30” / 760mm. During this customer’s process, the  production capacity is currently ranging from 450-500 stph / 400–450 mtph. They have been so impressed with the UJ640E that they have decided to move to a Sandvik Mobiles’ secondary stage of crushing, which will mean the jaw can be opened up and capacity substantially increased.

Designed with many features to maximize uptime, the Sandvik UJ640E features an 18 yard³ / 14 m³ feeder hopper extension to enable faster loading and provide a continuous feed to the Sandvik CJ615 single-toggle jaw, maximizing throughput and efficiency.

Although this mighty unit stands at an impressive 24’ / 7.3 m tall during operation and weighs in at 151.5 short tons / 137.5 metric tons, it is easily transportable in just two main sections. These sections are individually self-supported for easy assembly on site, resulting in more uptime and higher productivity.

Beast ‘Goliath’ beats the rest

John has been in the industry 35 years and knows a thing or two about crushing. He praises the UJ640E and adds that it really is a “Beast of a machine.” He says it is a very productive unit and the engineering design is 10 out of 10. “Durability and engineering of the machine is the best I have seen in 35 years of crushing.”

“Whenever the need has arisen for support with training, service or assistance, Crushing Tigers and Sandvik as an OEM have really stood up to the plate. I would not hesitate to recommend Crushing Tigers and the Sandvik brand to anyone in search of crushing and screening equipment.”
