The Industrial Solutions business area of thyssenkrupp, a world leader for planning, construction and service in the field of industrial plant and systems, will be unveiling the world’s biggest gyratory crusher at the bauma 2016 construction machinery show. The new machine is the KB 63-130, which despite a roughly 14% larger mantle diameter of 130 inches (approx. 3.3 meters) weighs in much lighter than its predecessor at 490 tons. Its throughput of up to 14,000 t/h is more than 30% higher than that of the predecessor model.
The debutant weighs less because the crushing technology specialists have said goodbye to usual design principles. “In the past the rule of thumb was the bigger the diameter, the taller the crusher,” says Detlef Papajewski, Head of Mineral Processing, thyssenkrupp Industrial Solutions. “But because users generally only need a bigger diameter to increase output, the KB 63-130 is exactly the same height as the other crushers in the 63 inch series despite the larger mantle diameter.”
The new machine sets new standards with a drive rating of 1,500 kW as well. It replaces the KB 63-114 gyratory crusher developed by thyssenkrupp in the mid-1990s, which is in operation in the world’s biggest gold mine in Indonesia. The 30 percent increase in throughput, combined with the significant weight reduction compared with its predecessor, has been made possible by combining proven FEM calculations (FEM = Finite Element Method) with advanced DEM simulations (DEM = Discrete Element Method).
The housing parts are in “fish belly design” known from other thyssenkrupp gyratory crushers. This special design reduces stresses in the crusher housing and increases its strength despite the optimized weight. Technical highlights of the new crusher include the rotatable countershaft assembly for setting tooth clearance, and the eccentric bearing assembly with top bevel gear. As well as allowing better balancing of the machine the new bearing system permits a much more compact design as well as maintenance-friendly assembly and disassembly.
The new gyratory crusher furthermore displays the typical properties of the 63 inch series: If it is used in a semi-mobile crushing plant (SMCP) for example, the weight of the crusher can be reduced by around 200 tons prior to relocation by removing certain parts. The parts in question, such as the heavy main shaft fitted with crushing tools, can also be easily removed for maintenance purposes.
To give potential users a better impression of the new crusher thyssenkrupp is also taking a new approach to presentation in the Mining exhibition area (hall B2 / booth 203) of bauma 2016. Papajewski: “We will be demonstrating new products like the KB 63-130 not just as 3D computer animations but also as 3D prints. It’s hands-on gyratory crusher technology.”
thyssenkrupp modernizes and standardizes series of Kubria® cone crushers
The Industrial Solutions business area of thyssenkrupp, one of the leading suppliers of crushing equipment for the minerals, mining and cement industry, has completely revised and standardized its series of Kubria® cone crushers and presents the Kubria® F/M 90 as an example at the bauma 2016. Its name comes from the size of the machine's lower cone diameter of 90 cm. "F/M" indicates that crushers of this type are used for fine and medium crushing, i.e. mainly as secondary and tertiary crushers.thyssenkrupp can look back on decades of experience in the development and manufacture of cone crushers. The proven design has been refined and optimized to further increase the crushers' throughput rates. At the same time certain modules have been standardized, which means that in the future Kubria® cone crushers will be available at significantly lower prices and with shorter delivery times.
The Kubria® cone crusher has proved its worth over many years under the toughest conditions in hard rock crushing. It is primarily used in the aggregates industry for crushing granite, basalt, gneiss and other hard rocks as well as in the ore and cement sectors. Depending on requirements, the F/M 90 can be equipped with a feed opening up to 180 mm and achieve throughputs of up to 200 t/h. The crushing chambers are designed to ensure the final product meets the highest demands with regard to shape and size.
The crushing cone is mounted in an eccentric bearing and driven by a spiral bevel gear with Cyclo-Palloid toothing, which permits the transmission of high crushing forces while ensuring very smooth running. The hydraulic cylinder beneath the machine serves both to adjust the crusher gap and to protect against overloading of the crusher. Together with the robustness of the overall structure, these features give the Kubria® high durability and reliability. As an option, the crusher is available with a tried and true Kubriamatic control system, which additionally monitors crusher-specific operating data such as gap width, output and pressure as well as temperatures and oil flow.
News of the innovations described above have already met with interest on the market. The Kubria® F/M 90 cone crusher on display is making only a brief appearance at bauma 2016 before being delivered to granite processor Tiefensteiner Granitwerk GmbH in Laufenburg to replace the present thyssenkrupp crusher after 28 years of non-stop operation.
hyssenkrupp presents the RollSizer DRS 660X3000 S – tailored to the requirements of the coal industry
As one of the leading suppliers of crushing equipment for the minerals, mining and cement industry, the Industrial Solutions business area of thyssenkrupp will be presenting the RollSizer DRS 660X3000 S at bauma 2016. thyssenkrupp RollSizers are capable of crushing medium-hard rock as well as sticky and soft material. The complete series has recently been standardized and further models have been added. As a result the entire range of applications, from primary to tertiary crushing of coal, can now be handled by RollSizers from thyssenkrupp. In addition these machines are now available at significantly lower prices and with shorter delivery times.With a roll length of 3 meters and shaft center distance of 660 mm, the RollSizer DRS 660X3000 S is the second largest member of the family of secondary and tertiary RollSizers from thyssenkrupp. The model, which will be exhibited during bauma 2016, is designed as SideSizer. Its rolls rotate outwards in opposite directions and crushing takes place between the rolls and the end walls of the housing. This is key to the crusher's extremely high throughput rates, clearly defined final product, and very compact design.
Like all secondary and tertiary crushers from the thyssenkrupp RollSizer range, the RollSizer DRS 660X3000 S is fitted with exchangeable crusher segments made of wear-resistant steel which are durable and also quick and easy to replace. In addition, all sections of the housing that come into contact with the material during crushing are lined with wear plates. This maximizes the service life of the overall machine and minimizes maintenance requirements.
The crushing combs arranged laterally on the end walls are available in various designs. Both the crushing combs and the end wall plating are horizontally adjustable so that product particle size can be precisely adjusted in line with requirements.
The DRS 660X3000 S operates with an extremely robust direct drive system consisting of two spur gears with fluid couplings. The couplings allow start-up of the Sizer even under the load of a full crushing chamber and at the same time provide overload protection. In the presence of a foreign body, the slip of the fluid couplings protects the machine against damage. The required drive torque is provided by two powerful 250 kW electric motors.
To ensure maximum operating safety, all thyssenkrupp RollSizers are fitted with sensors for monitoring the main machine parameters such as drive speed, bearing temperature and lubrication.
thyssenkrupp develops bucket wheel excavators cutting up to 50 MPa
The Industrial Solutions business area of thyssenkrupp, one of the leading providers of open pit mining technology and systems, will be presenting a new generation of compact bucket wheel excavators at bauma 2016: The “Barracuda” and the “Mine Shark”. Both machines will be able to work in hard materials with compressive strengths up to 50 MPa.
While bucket wheel excavators today mostly work in soft and medium-hard rock with an uniaxial compressive strength (UCS) of up to 20 MPa, the newly designed type of equipment is capable of working in a broad range of materials including coal, limestone, phosphate rock, potash, frozen materials in winter conditions as well as in its corresponding overburden layers.
In order to fulfill the requirements of the severe working conditions, special bucket and tooth designs have been applied by thyssenkrupp Industrial Solutions. These designs are based on innovative testing methods and include a larger number of teeth and buckets. This stage of development of bucket wheel excavators demonstrates the changing character of the extraction process from digging to cutting.
The combined extracting and loading process within a single machine eliminates hazardous and ecologically harmful blasting as well as additional loading activities. That is why health and safety standards at highest level can be ensured. Considering the fact that the new bucket wheel excavators are able to produce throughputs of over 3,000 t/h, whereas less number of vehicles and manpower are required, the operational expenditures can be reduced significantly.
To get a first impression of the new generation of compact bucket wheel excavators from thyssenkrupp, their working principle and application possibilities, a model of the “Barracuda“ can be seen and discussed at the thyssenkrupp Industrial Solutions booth (hall B2 / booth 203) at bauma 2016.
