The Terex® MACS plant is designed to be a highly mobile, high capacity, complete crushing and screening system. The MACS® name stands for Mobile Aggregate Crushing System because it is a complete "system", not just a collection of individual processing units. MACS units are highly integrated with each other to increase production and reduce set-up time. No cranes or booms are required for setup, all inter-plant conveyors are on-board.
The MACS utilizes larger crushers and screens than what are typically used in track mounted or wheeled plants. And now, the MACS plant offers the newest generation Terex® MVP450X cone crusher. The MVP450X boasts numerous features that increase productivity and ease of use. Major new enhancements include high speed clearing of jammed material and quick crusher separation capability for faster manganese changes.
The MACS unique trailer designs allow easy mobility. The crushing and screening units travel under 4115mm high and under 3660mm wide. Interplant conveyors are designed into the units so that separate transfer conveyors are not required. Folding conveyors and walkways set up using on-board hydraulics, thus eliminating the need for cranes or lifts. Also, large hydraulic support legs level and stabilize the units to speed setup.
Not only is the MACS plant designed for mobility and high production, but low cost of operation. The entire system utilizes industrial electric drives so that the system can be powered by either high efficiency generators or line power when available. The unique layout of the system provides operator visibility of the entire circuit from a central pop-up control house. High quality belt wipers and skirted conveyors are utilized throughout to reduce spillage. Maintenance is reduced since all components such as gear boxes, belt idlers, pulley bearings, 3-ply vulcanized belts, and flashings are selected for long life and low maintenance. Instant cone reset, strategic rock shelves and the TOPS 2.0 oil filtration system are additional maintenance reducing features.
Common components are utilized throughout the plant to simplify support and reduce the number of different parts. The control trailer is stocked with common parts and is organized in an easy to use visual inventory management system. Even a completely furnished mechanics tool chest and stocked hardware cabinet are included in the trailer. These features along with the quick setup provide for more time making product and less time wasted on moving and maintenance.
