COMPANY PROFILE-PAID ADVERTISEMENT Vermeer Establishes Solid Ground in Mining with Precision Excavation Technology Vermeer is a global agricultural, construction, environmental and industrial equipment manufacturing company. Its equipment can be found on jobsites around the world, serving the forage, underground infrastructure, pipeline, tree-care, landscape, wood waste processing, organic recycling and surface mining markets. Established in 1948, the Vermeer corporate headquarters is nestled in America's heartland. Pella, Iowa, is a small farming community, which juxtaposes the global presence of Vermeer. Vermeer has regional sales offices in the Netherlands, Singapore and Brazil. In addition to its 111.483.7 meters square (1.2 million sq. ft.) facility in Pella, Vermeer also has a manufacturing facility in South Dakota, U.S., and one in Beijing, China. Vermeer offers worldwide sales, support, service and parts through an industry leading, independent dealer network. A Better Way to Mine Vermeer has been long established as a company that strives for a better way of doing things. It is that mindset that allows Vermeer to look for new opportunities in new markets and continually evolve. Precision surface mining, as developed by Vermeer, allows mine operators to selectively extract mineral seams in surface mining applications. Reduced shock, vibration, dust and noise from precision surface mining enables mining operations to take place closer to roads and existing structures than would be permitted by drilling and blasting. Today's mineral prices are driving mine operators to explore new methods to extract mineral seams. Where the desired minerals are in thin layers, precision excavation can follow the layers and help prevent unwanted mixing of materials. Since it is entirely possible that all layers are economically valuable—but not compatible—the ability to separate them through precision excavation provides benefits over drilling and blasting. Precision excavation allows this process to be closely controlled so that almost all available products are recovered, resulting in a product of higher quality and value. Practical Technology The process utilizes Vermeer Terrain Leveler® surface excavation machines (SEM). The first Terrain Leveler SEM was developed when Vermeer took a rock trencher, removed the trencher attachment, and added a patented tilt-head milling attachment with top-down cutting action. Top-down cutting allows the cutter teeth to gain penetration without using the machine's tractive effort to drive the teeth into the minerals. As the unit travels forward and the drum rotates, the teeth on top of the drum advance over the top of the mineral surface. As the teeth come down toward the mineral surface, they make contact to instantly cut the material into uniform-sized product. Producing material in a uniform configuration allows minerals to be handled more efficiently than product produced by drilling and blasting. The uniform product T1255 Terrain Leveler SEM size also allows more efficient settings on secondary and tertiary crushing systems, savings that can continue well past the primary crushing stage. Precision excavation with the use of a Vermeer Terrain Leveler SEM produces a smooth floor that can minimize wear and tear on mine trucks and loaders, especially on machines with rubber tires. This can also allow the use of off-road trucks in place of mine trucks in many cases. Vermeer now offers two Terrain Leveler SEM models: the T1255 and the T1655— helping mine, quarry and civil work operations bring more precision to their excavation projects.
