Cemco, Inc.

Cemco says its Turbo 128 V-Twin VSI crusher is ideally suited for the production of 1 1/2-inch aggregate rock commonly used in concrete and is customizable for the production of several types of aggregate materials. The crusher is driven by a dual-drive V-Twin motor available with up to 900 horsepower. It weighs approximately 42,000 pounds and offers production capabilities of up to 1,000 tons per hour.

Williams Patent Crusher & Pulverizer Co., Inc.

Williams Patent Crusher’s Willpactor impact crusher, with a capacity of up to 2,500 tons per hour, was totally redesigned in 2004 with input from quarry operators. Medium chrome or manganese blow bars are indexable and easily replaced. The crusher’s adjustable, solid impact block allows product gradation control and reduces problems resulting from bridging. Moving the hydraulic breaker plate adjustment allows bridged material to fall into the path of the blow bars without interrupting operation.

McLanahan Corp.

McLanahan’s Universal MaxCap impact crusher is available in three different primary impact crushing models with capacities of up to 2,000 tons per hour. It offers the large expansion crushing chamber of a New Holland-style impact, while using the replaceable hammer technology of the Andreas-style crusher to break rock. It is said to deliver a high-quality, cubical product at a lower cost per ton.

Hazemag USA, Inc.

Hazemag says its primary impactors incorporate the latest designs and control technologies, ensuring consistent performance, economical operation, easy and safe maintenance, and extended service life. The crushers are fitted with the HAZtronic system that puts the operator in control. Production capacities range from 100 to 2,800 short tons per hour.

Eagle Crusher

Eagle Crusher’s large UltraMax 1600-69 has a production capacity of up to 800 tons per hour. The portable plant features a 13-ton sculptured solid-steel, three-bar rotor that is said to absorb the shock of large, aggregate materials and reduce down time. It includes the UM69 impactor with a 68-inch by 20-foot feeder, 69-inch feed opening, and fully lined hopper. The self-contained plant comes in standard 500-horsepower electric, optional 800-horsepower electric, and 521-horsepower diesel.
