Page 36 of 75 ROCK products • May 2018 • 35 FLSmidth FLSmidth's Traylor single- and double-toggle jaw crusher installations include some of the largest pri- mary jaw crushers ever built. Traylor jaw crushers are capable of withstanding the extreme conditions of the mining industry. Both the single- and dou- ble-toggle jaw crushers are constructed of heavy duty fabricated plate frames with reinforcing ribs throughout. The crusher's components are of high strength design to accept high power draw. Manga- nese steel is used for both fixed and movable jaw faces. FLSmidth, Hazemag The new Hazemag HSI series has been designed for economic secondary crushing and, depending on its configurations, processing of either soft and medium-hard or hard rocks. It is a modular system with the objective of fulfilling every scope of work in secondary crushing circuit. The machine's fittings as well as its control may be modularly adapted to the individual requirements and wishes of its operators – even up to a fully automatic mode. Depending on the properties of the feed material, the crushing ratio and the desired require- ments on the product grain size, feed sizes of up to 450 mm and throughput rates of 700 tph max are possible. Due to the hydraulic suspension of the impact aprons, not only a simple and fast adjustment of the opening widths is guaranteed, but also an overload protection. As soon as the crushing forces in the crushing chamber exceed a predefined limit value, the impact aprons retract and thus protect the built-in parts, such as rotor, blow bars and impact aprons, from potential damages. In addition, the hydraulic suspension offers the comfortable possibility of a simple readjustment and a quick on-the-spot-adaptation to the individual procedural condi- tions on the machine or from the switchboard. The HSI series may optionally be fitted with a grinding path. The grinding path restricts the amount of oversize and supports the gen- eration of a cubical and stress-free product. Hazemag, IROCK The TC-20 track impact crusher from IROCK Crushers com- bines a larger feeder, a high-performance four-bar impactor and heavy-duty components for exceptional efficiency, reli- ability and precision. The TC-20 produces a uniform, cubical product, and IROCK's hydraulically adjustable aprons pro - vide better control over sizing. The unit has the versatility to process soft to medium rock, recycled concrete and recycled asphalt. The rotor measures 40 in. x 56 in. and can process a variety of materials up to 24 in. in diameter. A 440-hp Cater- pillar C-13 ACERT Tier 3 engine powers the impact crusher, which can process up to 500 tph. IROCK,
