Engineering prowess: Cone crushers, vibrating screens that offer cutting edge solutions

 

thyssenkrupp has been at the forefront of providing advanced and reliable machines for the mining industry across the globe. Designed in Germany, the company’s huge selection of single machines and complete quarry-related solutions exhibit the innovative prowess of the company’s engineering abilities.

Applying an effective and efficient quarrying operation starts with the right machinery – and thyssenkrupp Industrial Solutions offers an extensive and proven portfolio of crushers, screens and other equipment for processing raw materials.

A broad range of jaw crushers, cone crushers, impact crushers and screens are used in applications that involve primary, secondary and tertiary crushing for a wide array of materials. thyssenkrupp crushers offer high to very high throughput capacities that span from 100 tonnes per hour to an enormous 14,400 tph.

thyssenkrupp’s Industrial Solutions business area is based on more than two centuries of experience with 11,500 employees situated across 70 locations around the globe. 

The company’s global team of employees can also provide detailed consultation and solutions to offer the best equipment set-up at a specific site – from quarrying to mining operations. Long after thyssenkrupp machines are installed, the company also provides qualified servicing and spare parts over the complete service life of the equipment.

thyssenkrupp offers “one-stop shop service” with its machines – from the engineering stage right through to consulting. At the customer’s request, maintenance and repair crews from thyssenkrupp Industrial Solutions can provide assistance.

CONE CRUSHERS

kubria cone crushers have a long-term track record as effective hard rock crushing machines. In the aggregates industry, kubria cone crushers are used for the secondary and tertiary crushing of granite, basalt, gneiss and several other materials.

Mantle diameters for the kubria cone crushers range from 750 millimetres to 2100mm, with three different models available, including fine crushers, intermediate crushers and coarse crushers.

thyssenkrupp has engineered the kubria fine and intermediate cone crushers with user-friendliness in mind. The machines have the added benefit of swapping out the feed opening by only replacing the crushing ring – without the complex hassle of replacing the crusher’s spider.

The top section of the kubria cone crusher’s chamber can vary in width, which allows for an early reduction to both small and large lumps of feed entering the chamber simultaneously. This leads to a uniformed wear level, lower wear costs and a 50 per cent longer service life.

For more durability, thyssenkrupp equips its kubria cone crushers with a hydrostatic thrust bearing. This robust piece of technology, in combination with the crusher’s flat crushing chamber, allows the machine to keep its bearing discs constantly lubricated. The flat crushing chamber also reduces the wear volume of the crushing elements by up to 20 per cent.

thyssenkrupp’s Kubriamatic electronic control and monitoring system is also included with the kubria cone crushers. The Kubriamatic system allows for fast and easy automatic adjustments to the crushing gap (even when under load), wear monitoring, automatic operation, and servicing.

A recent update to thyssenkrupp’s kubria product line has granted the machine several upgrades, including features such as an adjustable stroke which is standard across the entire kubria cone crusher range.

The adjustable stroke upgrade opens doors for further flexibility that was previously only available with large-scale machinery in the aggregates industry. This means thyssenkrupp’s team of innovative engineers have now made it possible to change the stroke of the crusher shaft without replacing parts to the eccentric drive unit, saving costs and boosting efficiency.

Additional advantages with the upgrade include benefits to the crusher’s efficiency and cost-effectiveness when the stroke is adjusted, including required throughput rate, required product quality, hardness of feed material and maximum permissible power consumption.

OTHER CRUSHER OFFERINGS

Designed for the most gruelling work environments, thyssenkrupp’s jaw crushers provide high performing, reliable and cost-effective solutions for quarries. The crushers have edge lengths that extend more than 2000mm and are the first choice for quarries and mines across the globe.

Two types of jaw crushers are currently available from thyssenkrupp, including single-toggle jaw crushers and double-toggle jaw crushers.

The single-toggle jaw crushers are made from a high grade steel that is put through stress-relieving heat treatment to prevent any potential stress from welding. Featuring a high throughput rate, the single-toggle jaw crusher has a swing jaw that is uniquely designed to be suspended directly on the eccentric drive shaft, with its lower part braced against the crusher frame through the use of a toggle plate.

These crushers use the toggle system to deliver higher capacities, with throughputs ranging from 250 tph to 1400 tph. The single-toggle jaw range of thyssenkrupp crushers include models that can be integrated into stationary plants, along with a model designed to be transported.

As for the company’s double-toggle jaw crushers, large levels of power transmission from the drive unit to the crushing mechanism enables crushing of the hardest materials.

The double toggle-jaw crusher’s system is controlled by a pitman that moves up and down via an eccentric shaft. This results in the toggle plates to flex and stretch, which causes the swing jaw to oscillate.

thyssenkrupp’s engineering prowess allows the swing jaw to oscillate as the crushing chamber narrows. The pressure generated from the narrowed crushing chamber is activated when the swing chamber moves forward. Once the swing jaw opens, the crushed material exits the crushing chamber and allows new material to enter.

LINEAR VIBRATING SCREENS

Crushers are not the only products that demonstrate thyssenkrupp’s high standards of engineering.

Its diverse range of linear vibrating screens provide several advantages for quarrying applications, including a constant, infinitely variable stroke, low overall height, top or bottom drive unit installation, throw angle adjustment and various other design characteristics that make it an efficient and viable screening option.

The latest generation of linear vibrating screens are fitted with twin out-of-balance drive units that generate the machine’s linear vibrations. A selection of five different drive units are available and depend on the size and how many are required for the specific job. The speed of the drive units can be varied through the optional frequency converter and the use of an electric braking unit enables rapid deceleration.

There are several types of linear vibrating screens that thyssenkrupp produces. This includes grizzly screens, which can be used as either scalpers, feed units or for coarse sizing. These screens have a capacity of 8000 tph, with a cut size of 250mm.

thyssenkrupp’s dewatering, depulping and deslurrying screens allow for the ability to dewater wet or wet-screened materials for transportation and feature depulping that recovers dense liquid or feeds thin pulps to a magnetic separator.

Sizing screens, which are particularly important in mechanically processing aggregates, are also available. thyssenkrupp’s standardised sub-assembly system can be configured with a maximum screen width of 3200mm and a maximum screen length of 9000mm. Different types of tensioned and flat screen media are offered, including perforated plates, a plastic modular system, woven wire mesh and cross-tensioned rubber media.

thyssenkrupp also offers circular vibrating screens that have areas from four square metres (m2) to 17m2. Options for two-, three- and four-screen decks are available. Unbalance exciters generate a circular motion which can be increased or decreased to meet the requirements of specific materials. With high throughput rates and high separation efficiency, the circular screens offer a reliable performance.
