New stationary units focus on meeting customer demand for customization, cubicity, and capacity.

Eagle Crusher
Jaw-dropping feed opening

The Eagle Crusher UltraMax 69 is said to provide large-volume primary/secondary crushing capabilities as well as the flexibility of either mounted stationary or in-pit portable use.

The plant’s 69- by 42-inch feed opening is 7 inches wider than the largest recycle jaw on the market. The plant can process a wide variety of feed material at rates of 400 to 600 tons per hour with reduction ratios of 24:1. The UM69 features a three-bar, solid-steel rotor that comes with a five-year rotor guarantee.

REMco
Anvil type crushing

REMco’s St/ar vertical shaft impact crushers use an anvil type crushing chamber to provide quick and efficient reduction of limestone and other less-abrasive stones. A variation of the SandMax and RockMax series, the machines share many of the same design components, as well as the bearing cartridge and main shaft design.

This model — suitable for second-, third-, or fourth-stage crushing — uses an innovative reversible anvil design that allows for maximum utilization of the anvil type wear iron. As they wear, the anvils can be easily turned for prolonged use.

Sandvik Mining and Construction
Automated crushing efficiency

A new crushing chamber and an automation system increase production capacity on the new Hydrocone H7800, from Sandvik Mining and Construction’s rock processing group. Rather than focusing solely on increased capacity, the crusher — which has 520 kW (700 hp) of power — is designed to improve reduction and to maximize product quality in relation to energy consumption. 

A built-in monitoring system checks lubrication temperatures and oil flow and switches on cooling fans and heaters as needed. The ASRi control system makes continual adjustments to optimize production and provides the crusher operator with an overview of the unit’s operation.

Metso Minerals
High-volume, low-cost processing

Metso says its Nordberg HP600 cone crusher is well suited for aggregate operations where big capacity performance is required in a cost-effective, high-availability unit.

The crusher includes many of the features of the HP line such as hydraulic setting adjustment, tramp release, and cavity clearing, but in a heavy-duty design. It can physically replace the smaller 5 1/2-foot Symons cone crusher without modification of feed and discharge transfer points, but is said to outperform 7-foot Symons crushers and to improve product shape.

Grasan
High-volume crushing

The stationary Grasan KRH1620 horizontal-shaft primary impact crusher is designed for high-volume aggregates operations. The crusher is said to reduce 24-inch limestone down to 6-inch minus in one step and to produce a cubical product at rates of up to 800 tons per hour. The plant features a Hazemag 1620 APPH impactor with fully automatic hydraulic cylinder system for increased crusher capacity, smooth operation, and uniform products. The 50-inch high, 80-inch wide inlet accommodates materials up to 36-inch cube. It is available with diesel or electric power.

Stedman
Handles sticky situations

Available in two-, four-, or six-row cage assemblies, the Stedman H series multi-cage mill can handle production capacities of up to 250 tons per hour. The new design features air cannons, heaters, and a hydraulic ram. The air cannons are mounted at the intake and discharge to help prevent build-up of wet, sticky material, while the heaters are also installed in the grinder housing to retard build-up of wet material. To lower maintenance costs, the hydraulic ram eliminates the gear head motor and rack and pinion used on previous cage mills.

Universal Engineering
High reduction ratios

The MaxCap primary impact crushers are said to blend the capacity of a New Holland style of crusher with the ease of operation and maintenance normally found in an Andreas style crusher. The result, Universal Engineering says, is a high-quality, cubical product at a lower cost per ton.

Available in four sizes with capacities ranging from 600 to 1,400 tons per hour, the primary stage impact chamber uses fixed impact plates to promote vertical expansion upon impact as well as controlled re-entry into the impact zone for maximum reduction. The secondary stage impact chamber features an adjustable curtain and cast wear plates.

Innotech Solutions, LLC
Customizable cone

The Globalcone GC300 features customizable variables to allow for the production of maximum saleable tonnages and minimal waste. Several throw and speed combinations are available on the fully balanced unit. Universal bowl and head assemblies allow the application to be changed from a coarse secondary to a fine tertiary by simply changing the bowl liner.

The crusher has full hydraulics to clamp, adjust, and clear, so if the crusher stalls for any reason, it can be safely and automatically cleared within a few minutes. The crusher design is automation friendly and features two sets of mounting holes for easy installation when replacing an existing crusher.

Cemco
Tailored turbo

Turbo Vertical Shaft Impact Crushers from Cemco are custom designed to satisfy individual product requirements. According to the company, conventional shoe impeller tables accommodate feed sizes up to 7 inches in mid-abrasive material, while maximizing production of cubical product and minimizing fines. Speed and crushing chamber adjustments can be tuned for specific applications. A full-flow, filter-protected oil system lubricates the pedestal’s heavy-duty, double-roll, spherical roller bearings. Optional oil heaters and coolers are available.

Lippmann
Heavy-duty processing

Lippmann’s massive model 5062 jaw crusher is designed for heavy-duty, high-volume aggregate crushing applications. The crusher is designed with an oversized, heat-treated eccentric shaft forged of special alloy to handle overloads and hard material, extra large radial thrust tapered roller bearings, a one-piece cast pitman, and a heavier, stronger, one-piece, stress-relieved frame. The hydraulic adjustment system allows the setting to be adjusted while crushing. The crusher is said to offer a true feed opening, better motion, a greater reduction ratio, and increased throughput.

DBT Mineral Processing
Impact roll crusher

DBT says that it manufactures products that work on the principle of linear, obstruction-free mineral flow. Its impact roll crushers use standard components to allow a modular design that can be tailored to a customer’s special requirements. The differences in the design principle are the result of horizontal crusher flow used by the impact roll crusher as opposed to conventional vertical-flow crushing. The low design results in the possibility to feed at grade while reversible material flow ensures jam-free operation.
