1 Industrial Solutions RollSizer. The different way of crushing.

2 2 RollSizer by ThyssenKrupp: The different way of crushing ThyssenKrupp Industrial Solutions is one of the world s leading manufacturers of machines and plants for the processing industry. Based on decades of experience, our engineers are engaged in research and development. The results have become an integral part of processing technology. Customers worldwide benefit from our innovations. Whether standard or customized designs ThyssenKrupp Industrial Solutions always provides comprehensive solutions tailored to customer needs reliably and cost-effectively. 1 1 Lignite processing plant built by ThyssenKrupp Industrial Solutions. 4 RollSizer DRS 660 x 3,700 SideSizer.

3 Fields of application and design characteristics 3 Fields of application: ThyssenKrupp RollSizers are used for the primary, secondary and tertiary crushing stage of medium-hard as well as sticky and raw material and overburden soft materials by following industries: Cole processing Lime and Cement works Natural stone industry Raw material processing The low height of the RollSizer allows an easy integration of the machine into existing plants and makes it suitable for mobile, semi-mobile and stationary crushing plants. 2 2 RollSizer DRS 800 x 1,500 CS Designed as CenterSizer Used for primary crushing of silicate rocks Capacity: 700 t/h 3 Semi-mobile RollSizer plant RollSizer DRS 660 x 1,500 CS Designed as CenterSizer Used for primary crushing of limestone Capacity: 550 t/h Design characteristics: Compact, flat design Reliable, robust and highly efficient technology Very low fines content in the crushed product due to the crushing method and low speed of the crushing rolls 3 Reduced dust generation compared to other crushing methods Combination of screen and crusher in one machine High shear and tensile forces at a low rotor speed High throughput rates at low operating costs Reduced wear due to optimised crushing tool geometry and special wear material Low-wear crushing method (bending and tensile forces, low circumferential speed) Reversible operation.

4 4 CenterSizer 4 5 Mode of operation CenterSizer The CenterSizer crushes the charged material between the crushing teeth in the middle of the crushing chamber. The required shear and tensile forces are generated by high rotor torques at low circumferential speeds. Similar to a wobbler feeder fines can pass between the crushing rolls without being crushed any further. Therefore the specific power consumption, the wear rate, and the fines content in the crushed product are considerably lower compared to other crushers. CenterSizer for the primary and secondary crushing stage CenterSizers produce a clearly defined product size with a low oversize content. By installing a CenterSizer as secondary crusher the material can be crushed to a final product size of 50 mm. The crushing ratio depends on the application and the design of the CenterSizer and varies between 3:1 and 6:1. Depending on the RollSizer type feed capacities up to 10,000 t/h can be achieved and lumps with a size up to 2,000 mm can be crushed. Drive CenterSizer and SideSizer The crushing rotors are driven either by a synchronous gear box and one drive line or by two independent drive lines. The hydraulic-mechanical or electro-mechanical drive lines can be arranged on one or on both sides of the crusher housing. Crushing tools CenterSizer The design of the crushing chamber (arrow or spiral arrangement of the crushing tools) and the fastening system of the crushing teeth are chosen depending on the application and the arrangement of the RollSizer to the flow of material. The available fastening systems vary from replaceable tooth pics to completely replaceable teeth rings. To achieve a long lifetime the material of the crushing tools is chosen according to the application. 4 RollSizer DRS 660 x 2,000 Designed as CenterSizer Primary crushing application 5 RollSizer DRS 800 x 1,500 Designed as CenterSizer Primary crushing application 6 CenterSizer Mode of crushing 6

5 SideSizer 5 7 Mode of operation SideSizer The SideSizer crushes the charged material at the sides between the crushing teeth and the adjustable crushing combs. Additionally fines can pass between the rotors in the middle of the crushing chamber without being crushed any further which results in a low fines and dust content in the crushed product. The material is crushed by shear, tensile and cutting forces which are generated by high rotor torques at low circumferential speeds. SideSizer for the secondary and tertiary crushing stage SideSizers produce a clearly defined product size due to the exactly determined geometry of the crushing combs. By operating a SideSizer the material can be crushed to a final product size of 30 mm. 8 The adjustability of the crushing combs allows a high flexibility in altering the final product size. The crushing ratio depends on the application and the design of the SideSizer and varies between 3:1 und 4:1. Depending on the RollSizer type feed capacities up to 2,500 t/h can be achieved. Crushing tools SideSizer Easily replaceable crushing segments and crushing combs are preferably installed in a SideSizer. To achieve a long lifetime the material of the crushing tools is chosen according to the application. 7 and 8 RollSizer DRS 660 x 3,000 Designed as SideSizer Secondary crushing application 9 and 10 SideSizer Mode of crushing 9 10

7 Research, Development and Services 7 ThyssenKrupp is attaching great importance to research and development. Committed employees, experience and the ability to tread new paths together with the innovative power, flexibility and know-how are the foundation on which the successful cooperation with our customers is built. This ranges from basic analyses to measurements on new and old crushers. At first analyses of the deposits or the feed material are carried out by means of up-to-date methods allowing a material characterization and based thereon the right choice of a suitable crusher. Furthermore, by these basic analyses the best possible adaptation of the crusher can be ascertained, like e.g. the correct sizing of individual components by means of the finite element analysis. The computed values will then be field-tested using a newly developed control and diagnosis system which allows the control of the most important operating data. Our services include project research, damage analyses, planning and modification aimed at a modernization and an increase of the output of machines and plants in conjunction with a worldwide after-sales service which also covers the equipment of other manufacturers. Maintenance and repair services offered by ThyssenKrupp include expert onsite consultancy. Repairs are carried out by highly qualified staff using high-quality and tested spare parts.
