Seeing the benefits of mobile versus stationary, they have been operating with Sandvik mobile crushers and screens and embracing the latest technology for almost 20 years.
Brubaker-Mann Inc. is a family-owned business which was established in 1950 by William Mann, and his cousin Ronald Brubaker for the production of colored rock. They own eight different quarries throughout the Mojave Desert and offer a large selection of natural rock colors including gold, green, white, pink, red and lilac all extracted from their different quarries. The end product is used by landscapers and homeowners for decorative and roofing purposes.
Operating initially with their own mill in Barstow, the material was transported to the quarry for processing. As demand grew, they constructed their own stationary crushing plant built from scrap metal, which enabled them to increase capacity and reduce physical labor. In the late ‘90s, Julie Mann, William’s successor and now President of Brubaker-Mann, decided it was time to invest in new plant to meet further increased demand. She quickly saw the benefits of mobile crushing and screening plant. They were able to move the equipment on site to the quarry face, as well as from quarry to quarry, instead of bringing the material to site. This reduced truck and haulage costs, as well as increasing production capacity and enabling a wider range of materials to be produced.
Purchasing a tracked jaw crusher, an Extec C-12, and an S-5 Doublescreen at that time, Brubaker-Mann have been impressed with the performance and operation of the machines over the years and have since replaced these, purchasing current variants of these models; the Sandvik QJ341 jaw crusher and two QA441 Doublescreens. They have also invested in a QH331 cone crusher to shape the material and produce a higher quality product.v
“It was the simplicty of the crushing and screening operation and the terrific production capability of the machines that initially confirmed our purchse. The equipment can be easly propelled around site, providing an operator-friendly system that enables us to make quick and easy adjustments.”
Brubaker-Mann is committed to complying with all environmental regulations and continually update their fleet to ensure compliance with new engine requirements. Sandvik mobile crushers and screens are fitted with the latest emissions-compliant drive trains for maximum performance and cost efficiency.
Extended life and efficient operation
The latest models also come with a number of updated features for efficient operation, extended life and increased throughput. These include the Optitooth™ jaw plates, which are fitted as standard to the QJ341 and Q-Range models within the jaw crusher range. Current models come fitted with Sandvik My Fleet as standard, including 7 years complimentary data subscription. This gives access to a wide range of data to enable the plant to be optimized for best performance and maximized uptime through planned service and preventative maintenance.
Their latest purchase, a new QA441 Doublescreen, was delivered in February this year to replace an older model. The Doublescreen technology is ideal for Brubaker-Mann as a large producer of aggregates, as the two screen boxes are independently adjustable and can be configured to over 20 different screening angles. This enables fine-tuning of the screen to suit the specific requirements of the application and produce a clean graded product at high throughput.
They decided to continue with Sandvik for familiar use of the equipment and the continued quality and service, says Julie.
“Over the years, the Sandvik machines have performed very well, and the new screen continue along those same lines.”
Other key criteria in their purchasing decision, in addition to the reliability and productivity of the equipment, were the serviceability, parts availability, as well as the quality of service provided.
Over the past year, Brubaker-Mann have been supported by Sandvik Mobiles’ authorized distributor in California, Volvo Construction Equipment and Services (VCES). VCES are the distributors for Sandvik mobile crushers and screens for the whole state of California and provide sales, rentals, parts and service. Julie says, “VCES brings a high level of service and parts support, and we cannot fault the service we have received from them.”
The quality of product from Sandvik, together with the esteemed service and support from VCES provides a winning combination, which matches Brubaker-Mann’s business philosophy. They emphasize customer service and are well positioned to maintain their reputation and leading supplier of decorative rock in the market.
