Crushers

Your complete guide to new and updated equipment and supplies in the aggregates industry.

By Aggregates Manager Staff

ConExpo-Con/Agg 2011 was the staging ground for the introduction of many new products and equipment for the aggregate industry. In fact, there were so many introduced at the show that we couldn’t fit them all into this one issue. So we have broken them up into categories and will run one or two categories at a time in this and the next several issues. We decided to lead off with crushers, the bad boys of the processing plant.

Expanded cone options

FLSmidth Pekin, LLC, recently merged into FLSmidth Salt Lake City, Inc., debuted three new models of its Raptor line of cone crushers at ConExpo-Con/Agg. The new models include the XL500, XL1300, and XL2000 cone crushers. The 500-horsepower XL500 is designed for secondary crushing with features such as a large feed opening, high pivot-point crushing action, and wide crushing stroke. With a head diameter of 59.06 inches, it can accept feed up to 25 percent larger than a crusher with less throw or a similar head diameter. The XL1300 is a 1,300-horsepower machine. With 2,000 horsepower, the XL2000 offers an extra-heavy-duty, high-grade steel mainframe; an automated control package; and a hydraulic tramp release cylinder and clearing system. These new features are based on customer input.

Durable construction, high production

The new Terex Cedarapids JS4552 jaw crusher, on display at the show, features durable construction and an aggressive crushing motion for high productivity. The company says the crusher is easy to operate and maintain, and offers new levels of reliability and convenience. The jaw die retention system and hydraulic assist shim system allow more uptime, as well as fast and easy jaw setting adjustments without the use of tools. Jaw die wedges, which are accessible from the sides of the crusher, are easy to remove and can be changed quickly, reducing downtime.

Highly versatile crusher

Powerscreen, a Terex company, showcased its latest XH500 horizontal shaft impact crusher at the show. Representing the latest generation of highly versatile track crushers, the company says it is designed for maximum throughput of up to 500 tons per hour and is ideally suited for contract crushing due to its high productivity and ease of set-up, operation, and maintenance. Key features include a vibrating pan feeder, a double-deck live pre-screen, a feeder load management system, an under pan feeder, an efficient crusher direct-drive system, crusher hydraulic overload protection, a hydraulic raise/lower product conveyor, a new PLC control system, and large stockpiling capacities.

Works in conjunction with primary plants

Telsmith’s new Tel-Trax Model TC52 high-capacity, track-mounted cone crushing plant made a big impact on show goers. Built around the 400-horsepower model 52SBS cone crusher, Telsmith says the TC52 boosts tonnage output in secondary and tertiary applications, while accepting larger feed (up to 12-inch topsize) than 300-horsepower units. The unit is outfitted with automation controls that automatically adjust the feed rate and reduce the need for operator oversight by monitoring parameters such as crusher overload, feed bin levels, diesel power supply, and the discharge conveyor. The automated controls package also allows a soft link to additional Tel-Trax crushing and screening plants to provide a completely linked and integrated processing solution.

Track-mounted jaw

Kleemann debuted its MC 110 Z track-mounted jaw crusher at ConExpo-Con/Agg. The unit boasts a high-torque reversible hydraulic jaw and fully hydraulic gap adjustment that makes it friendly for the contractor market. The R version has an integrated grizzly, while the Z version has a fully independent, double-deck pre-screen. The unit can be fitted with an optional final screen and oversize discharge, which allows the operator to produce a final graded product with a single machine. The fuel-efficient crusher uses a Cat C9 engine and is configured for operation by a single person who can feed raw material into the crusher while using a wireless remote-control unit in the cab of an excavator or loader. Crusher dimensions are 44 by 28 inches; transport weight is 99,200 pounds; length is 47 feet, 5 inches; and width is 9 feet, 10 inches.

Quattro movement for increased feeding capacity

Atlas Copco showcased its new line of Powercrusher track-mounted mobile crushers and screeners, including jaw crushers, impact crushers, and cone crushers with a crushing capacity from 242 to 606 tons per hour, and screeners with a capacity of 242 to 485 tons per hour. The four jaw crushers incorporate “Quattro Movement” made possible by an up-thrust toggle plate position. This causes a figure-eight motion in the moving jaw, which increases the feeding capacity and produces a post-crush at the crusher outlet. The six impact crusher models use optimized geometry in the crusher box with hydraulically adjustable swing beams, resulting in a minimal percentage of oversized material and high reduction ratios and throughputs. The PC 1000 cone crusher is designed to accept an “all-in” feed that increases particle-on-particle crushing, which improves the quality of the end material shape, decreases wear, and may eliminate the need for pre-screening.
