Crushing Up a Storm: Here Are Some of the Latest Crushing Products on the Market.

There is never a lack of innovation when it comes to crushing equipment. Here are some of the latest products on the market, some introduced at bauma, AGG1, and over the past year.

Kleemann Mobirex MR 130 Zi EV02 Impactor

High-performance and enhanced aggregates processing technology built into Kleemann products like the Tier 4 final-compliant Mobirex MR 130 Zi EV02 impact crusher shown at AGG1, and the smaller MR 110 Zi EV02, are boosting productivity and product quality for operators.

These mobile impactors can be equipped with optional, highly productive secondary vibrating screen with extra-large screening surface mounted on the discharge conveyor. This secondary screening unit can produce spec material, potentially eliminating the need for a separate screen.

The feeding unit has hydraulically folding hopper walls and locking system, which speeds setup. A vibrating, independent double-deck prescreen between hopper and crusher eliminates fines from the product flow before they ever enter the crusher, reducing wear and cutting fuel costs.

These crushers feature a new inlet geometry, which allows even better penetration of the material into the range of the rotor. Also, the wear behavior of the new C-form impact ledges has been improved to such an extent that the edges remain sharper longer, leading to improved material shape. The rotor ledges are held securely by a new and extremely user-friendly clamping system, which means that they can be changed even quicker, and thus contribute to greater plant uptime.

Outstanding performance is made possible in part by the extremely efficient direct drive, with which the machines are equipped. A latest-generation diesel engine transmits its power almost loss-free directly to the flywheel of the crusher, via a robust fluid coupling and V-belts. This drive concept enables enormous versatility, as the rotor speed can be adjusted in four stages to suit different processing applications.

tyssenkrupp Multirok Vertical Shaft Impactors

Multirok vertical shaft impactors, manufactured by thyssenkrupp can be used flexibly in stationary, semi-mobile and mobile plants, thyssenkrupp also carries out intensive research and development work to continuously optimize the proven concept.

In vertical shaft impactors, the material is fed centrally into the rotor from above. The centrifugal forces inside the rotor throw the material against the sidewall, resulting in a highly cubical product.

Multirok impactors from thyssenkrupp are available in two sidewall and rotor variants: the sidewalls can be equipped either with anvils or with a material bed. For the rotor there is a choice of open or closed configuration. The optimum design is selected on the basis of the feed material and the specific customer requirements.

thyssenkrupp offers its Multirok vertical shaft impactors in three sizes: Multirok 7 for throughputs of up to 200 tph; Multirok 9 for throughputs of up to 300 tph; and Multirok 9 Duo --which has two drive motors--for throughputs of up to 400 tph. The product size is mainly influenced by the rotational speed of the rotor. The Multirok can be equipped with a variable frequency drive to adjust the rotor speed. This ensures quick and easy product changes during operation.

Maintenance is a key issue in the operation of vertical shaft impactors. Multiroks from thyssenkrupp are of robust design and offer a long service life while ensuring easy access to key components. The rotor liners and liner plates on the rotor and the anvils in the anvil ring can be accessed and replaced simply via a hydraulically removable housing cover. All wear parts are made of highly wear-resistant materials.

Hazemag HIS Secondary Impactor

The 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 a secondary crushing circuit. The machine's fittings as well as its control may be modularly adapted to the individual requirements and wishes of the operators --even up to a fully automatic mode.

Depending on the properties of the feed material, the crushing ratio and the desired requirements 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.

After the retracting procedure, the impact aprons move back in a controlled manner into their original position, so that the crushing operation can be continued without interruption.

In addition the hydraulic suspension offers the comfortable possibility of a simple readjustment and a quick on-the-spot-adaptation to the individual procedural conditions 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 generation of a cubical and stress-free product.

Superior Primary Crusher; VSI

Superior Industries Inc. offers a machinery solution for crushing applications called the Liberty Jaw Crusher. Functioning as a primary crusher, the unit compresses material in stone, concrete, asphalt and ore applications.

The Liberty Jaw Crusher is engineered with an aggressive nip angle that maintains the machine's ability to consistently grab and process material at a high level of efficiency. In addition, a set of integrated lifting points are designed into the jaw dies for safe replacement or installation.

Other unique features include pitman toe protection. This replaceable component offers an insurance policy if wearing occurs in the pitman fabrication. Furthermore, the unit's motor is frame-mounted, allowing a smaller footprint and freeing up deck space for maintenance. More maintenance time is freed with the addition of hydraulic tensioning system and hydraulic wedge adjustment.

Superior's Liberty Jaw Crushers are manufactured in feed openings of 18 in. x 36 in. to 36 in. x 48 in.

The company has also debuted its new patent pending Valor Vertical Shaft Impactor (VSI). The VSI is Superior's second equipment solution for crushing bulk materials after launching the compression style Patriot Cone Crusher late last year. Impact style crushers, like the Valor VSI, produce a more cubically-shaped product.

Incorporating criteria from several of its existing customers, Superior said its engineers produced a stronger, safer and more convenient design. For example, the VSI is equipped with a cartridge style, right angle pinion gearbox. This allows for a safer deck-mounted motor arrangement, which also simplifies access to the drive and its components.

In addition, a hydraulically-powered lifting lid allows for safe and easy access to the crushing chamber. Maintenance inspectors are protected by a combination of automatic and manual safety interlocks. Thirdly, an innovative autogenous rotor design encourages more rock on rock crushing, which greatly extends the life of many internal parts.

Superior manufactures models of its new Valor VSI for rates up to 800 tph (725 mtph) and maximum feed sizes up to 8 in. (203 mm).

McLanahan MSP Cone Crushers

The technology that makes a McLanahan MSP Cone Crusher outperform competitive cones on the market is the combination of all of the factors of performance i.e. balanced eccentric, higher speeds, fulcrum point position, and stroke. By using sound engineering with years of field testing a truly tried and tested new cone crusher has emerged.

A balanced eccentric coupled with a fulcrum point ideally placed over the crushing chamber yields highly effective compression crushing. This allows higher eccentric speeds to maximize performance without disruptive forces. The eccentric stroke is designed to work with the eccentric speed and fulcrum position to produce higher yields and minimize recirculating loads. The torque and resultant crushing forces are as effective as virtually any cone crusher on the market.

Spiral bevel gears provide the turning force to the eccentric. The spiral gear is mounted on a sturdy countershaft of the cone crusher, which rides in bronze bushings. The gears are precision cut for quiet operation. Misalignment problems are eliminated.

The MSP Cone Crusher features one of the largest volume displacements by a crusher head. When there is a large volume of material displaced this way, it means that more material is crushed in each cycle, more material can be fed to fill the larger void left when the crushing head recedes, and more material flows through the crusher due to the larger throughput and gyrating cycles allowing material to drop further. The benefits of high efficiency, greater crushing force and high capacity coupled with the durability the market expects are the reasons why this design is the best way to increase your productivity and profitability.

MSP Cone Crushers are built to make operations run smoother and easier. It's simple control panel provides users with the necessary information to properly run the crusher. For example, the MSP Cone Crusher shows the exact cone setting to allow the operator to stay on top of a critical set point.
