With an output of up to 717 US tons per hour, the MOBICAT MC 120 Zi PRO is impressive in natural rock applications. The powerful jaw crusher has a feed opening of 48″ x 32″ and is equipped with an extra-long articulated crusher jaw. To ensure the best possible material flow, the continuous feed system (CFS) adapts the conveying speed to the fill level of the crusher. On most jaw crushing systems, the operator has the time-consuming task of clearing the crushing chamber in the event of material blockages. Not so with the optional crusher unblocking system. Should material bridging occur in the jaw crusher, the crusher can be reversed with the aid of the electric crusher drive and in this way the blockage can be cleared in no time.

McLanahan Corporation’s UltraWASH 6505 modular Wash Plant is built with several features, including the patent pending Eze-Riser, patent pending Fines Forward Slide and a sump conversion kit. The Eze-Riser works together with the pump service trolley to enable safe and efficient pump maintenance, such as changing the impellers or replacing the casing liners. A foot pedal lifts the discharge pipe from the pump and utilizes a locking mechanism to then holding the pipe aloft, offering the clearance needed for the pump to roll out on the trolley service platform unrestricted. The manually adjustable Fines Forward Slide can divert a portion of raw fines into the coarse sand processing stream. This balances the downstream process to optimize plant capacity. Alternatively, by substituting the last row of fine material screen panels with coarse material screen panels, the Fines Forward Slide will allow alterations of the proportions of fine and coarse decking areas above, while still preventing the loss of coarse material into the fines processing stream. The sump conversion kit allows the operator to quickly and safely change between a one-or-two-pump setup. The sand process can also be altered to process a single wash, a double wash or a two-product sand.
The S250 Screener is one of the largest and most portable vibratory screening plants in production.

The crusher processes a wide variety of materials like limestone, granite, basalt, and concrete effectively. The all-electric portable jaw crusher has an integrated vibrating feeder and can be easily loaded using a wheel loader, excavator or dump truck.
Philippi-Hagenbuch Inc.’s Positive Seal Autogate Tailgate is specifically designed for off-highway trucks and roll-off containers that require a 100% seal. This new design can be paired with PHIL’s proprietary fluidic seal material to create a water-tight seal that contains liquid materials within an off-highway truck body or roll-off container when environmental regulations or local laws make even slight spillage undesirable. The new Positive Seal Autogate Tailgate can be designed for practically any size off-highway truck or roll-off container. Paired with PHIL’s simple yet robust outrigger, its traditional scissors-style mechanism provides an industry-leading maximum opening clearance at full dump. In the closed position, the new design positively locks into place and will not open under normal conditions without the body or container entering the “dump” mode.
The new design builds up the rearmost portion of the truck body or container to create a cohesive flange from which the tailgate compresses. Two hooks on either side of the base of the flange intercept a corresponding tag on the tailgate, allowing the tailgate to pivot inward as the sidearm and over-centre locking mechanism compressively lock the rear tailgate into place.
Polydeck’s Kwikdeck system is a frame conversion that lets a producer try synthetic screen media virtually risk-free. Created to work with crowned decks, Kwikdeck is a modular screen media system that can be modified to fit the dimensions and configurations of most vibrating machines without altering the existing deck frame. Kwikdeck takes about 45 minutes to change out a 4×6 deck and uses existing side clamp rails making Kwikdeck perfect for portable screens that need to alternate between wire cloth and synthetic media. With a wear life ten times longer than wire screens, operators can save on labor costs while increasing production using Kwikdeck.

Stop by the Trimble booth to learn more about Trimble payload and productivity management technology, which allows quarry operators to track and visualize loader, excavator, haul truck, processing productivity and efficiency visibility with simple graphs and metrics.
With its latest innovation, WITOS Paving Docu, VÖGELE is complementing its two existing job-site solutions: RoadScan, the non-contacting temperature-measurement system with which the paving temperature can be monitored across the full pave width, and WITOS Paving Plus, the telematics solution for coordinating and actively optimizing all processes from the mixing plant to the paving process in real time. WITOS Paving Docu bridges the gap between the two: The solution is aimed squarely at contractors who want to record and analyze more than just paving temperature, but don’t need the full range of WITOS Paving Plus functions, which includes process optimization and integrated planning. At a job site, foremen can use a special smartphone app and paver operators the machine terminal to initiate jobs in WITOS Paving Docu and record a wide array of additional paver and paving data, such as working width, paving speed, interruptions to paving and effective paving time. Delivery notes can also be scanned in using a QR code or entered manually, allowing paved areas, paved material quantities and areal densities to be calculated continuously. At the end of a day’s paving, job-site reports are sent automatically by e-mail to selected recipients. They include information on key job-site data and machine utilization.
Wirtgen’s W 380 CRi can recycle the road surface to a full depth of 300 mm/12 in., so it is also suitable for full-depth recycling (FDR). It can also restore road surfaces beyond the available working widths of 3,200 mm/10 ft. 6 in., 3,500 mm/11 ft. 6 in. and 3,800 mm/12 ft. 6 in. Thanks to a mixing capacity of 800 t/h (787.2 US t/h) in combination with rear loading onto a road paver with the appropriate stockpiling and paving screed, even very wide road surfaces can be rehabilitated in a single pass.
The W 380 CRi can also be used as a high-performance milling machine. Thanks to its high engine power of 1,054 PS/1,038 HP (EU Stage 5/US Tier 4f) and conveyor capacity, the W 380 CRi can manage removal work to a milling depth of 350 mm/14 in. This enables large-scale rehabilitation work to be carried out quickly, such as on motorways, runways at airports, or the removal of complete asphalt packages, as well as the homogenization and granulation of damaged asphalt layers.
