40 • ROCK products • May 2018 Crushing Feature Telsmith Telsmith promoted its Hydra-Jaw Crusher at AGG1 2018 in Houston. To showcase the Telsmith promise that "The Extra Mile Isn't Extra. It's Included," the team explained how Telsmith goes the extra mile with their concept to completion services for the Hydra-Jaw Crusher, which provides ease of maintenance and durable components for increased uptime and safety. The Hydra-Jaw is ideal for a number of process- ing applications such as aggregates, mining, and recycling, and is available in three configurations; stationary, track and wheeled portable plants. The jaw series includes four models, the H2238, H2550, H3244 and H3450 Innovative in its simplicity, the Hydra-Jaw toggle tensioning system saves time and costs by eliminating the need to adjust springs when changing the setting. A simple mechanical spring assembly secures each hydraulic toggle end to its respec- tive toggle seat. By securing each end independently, there is no need to adjust the springs when the setting is changed. Quick to assemble and reliable in operation, the assembly requires no special tools or maintenance. The core of the Telsmith hydraulic toggle system is the robust Hydra-Jaw hydraulic cylinder. Custom built specifically for the crushing environment, the cylinder incorporates a large piston for high crushing forces and an "oversized" rod for stability and strength. The unique bushing and seal are designed to hold up to the rigors of constant crushing in a dusty environment to deliver long service life with minimal maintenance. Telsmith, Terex MPS Terex MPS's CRC1150S closed-circuit crushing plant features the TC1150 300-hp Terex Cone Crusher and the TSV6203 6- x 20-ft. triple-deck screen. The CRC1150S offers big capacities in a highly portable plant. Key features include: • TSV6203 triple-shaft, high g-force screen. •  TSH6203 triple-oversized, surge buffering, cone-shaft, high g-force, triple-deck screen. •  Compact low maintenance "walk-over" flex shaft screen drive. •  Quick release, hopper with integrated overflow chute system. • Tri-axle suspension with 57.5 in. axle spacing. •  42-in., 20-hp main feed conveyor, impact rollers in feed hopper, rubber discharge hood. • Metal detector on main feed conveyor. •  36-in, 10-hp under-crusher conveyor with diverging hopper. • 54-in., 10-hp under-screen fines conveyor • Simple transfer and mid-plant product chutes. • Maintenance friendly chute liners; bolted side liners and keyed bottom liners. •  Four-section blending system to mix second and bottom decks products. • All motors including 300-hp crusher motor. Terex MPS, Terex MPS, Terex Finlay The Terex Finlay I-140 direct drive horizontal impact 50- x 48-in. crusher with variable speed gives operators unprec- edented levels of production in both recycling, mining and quarrying applications. The robust and proven Terex CR032 chamber gives excellent reduction ratios and high consistency of product shape. A significant engineering approach being introduced in this model is the material flow through the plant. The flow of material has been significantly improved by increasing the width of components as the material moves through the machine. The machine features an advanced electronic control system that monitors and controls the speed of the rotor and regulates the heavy duty vibrating feeder (VGF) with integrated pre-screen to maintain a con- sistent feed of material into the impact chamber for optimal crushing conditions. Material from the integrated pre-screen can be diverted to a stock pile via the optional by-pass con- veyor, or it may join the crushed product on the main belt. The standard hopper capacity of 6 m³ (7.5 yd.³) places the machine at the forefront in this competitive market sector. Terex Finlay.
