Agitated bead mill
The agitated bead mill is an additional stage grinding solution, particularly efficient for finer grinding. For the process of mechanochemical activation the agitated bead mill is the essential element to enhance material properties for various applications and industries. Therefore, it enables customers to produce ultra-high performance cements or sustainable cements with a lower clinker factor without losing grinding capacity and gaining flexibility. The reduced specific power consumption, the beneficial particle size distribution, higher early strength and short project duration without significant downtime lead to a quick payback. The mill is completed with process know how as well as digital and laboratory services.

Agitated bead mill services by thyssenkrupp
Focussing on customer’s target cement portfolio and operating result thyssenkrupp services start with the analysis of current operation and market and supports as far and as long as the customer requires. Therefore the polysius® booster kit comprises complementary services and supplies around the agitated bead mill. thyssenkrupp – as a full rang supplier to the cement industry – offers all alternative solutions in their portfolio and consult the customer on the solution with the highest benefit.
The process and mechanical engineering audits of the existing plant and main machines like ball mill, high pressure grinding roll (HPGR), separator and vertical roller mill (VRM) is the basis of the polysius® booster kit.
A grinding plant – including the agitated bead mill, a ball mill, HPGR, combi grinding and VRM - and laboratories within thyssenkrupp R&D center enable offering of polysius® lab services. Here the adaptation and optimization of binder properties by physical, chemical and mineralogical analysis as well as mortar testing are carried on customer’s behalf. For this purpose, calculation models for relevant mortar properties are created on the basis of existing analysis in order to predict the effects of process changes. The use of new measurement technology and equipment and the evaluation of new measurement methods complement the polysius® booster kit.
The digital services being developed will analyse the production data, report on current operation, give hints for process optimisation and predict cement quality (e.g. early strength or workability) and maintenance. The grinding system simulator enables capacity and production planning including new cement types. Services and training can partly be carried out online. Support in the use of new measurement technology and equipment and the evaluation of new measurement methods.
Having the expertise along the entire cement production our approach is to provide a 360° service for our customers to ensure best performance of your current and new installation. For the agitated bead mill an uptime between maintenance intervals at least matching those of ball mills is currently expected. For the pilot installation almost no wear was experienced after 2000 operating hours. The replacement of wear parts, liners and grinding tools can quickly be executed by trained plant personnel or thyssenkrupp Polysius.
