The TowerMill, which has now been in existence for no less than 50 years, is one alternative tothe horizontal ball mill and offers several advantages. The TowerMill is widely used in (coal-fi red)electric power plants for the grinding of raw material for the FGD (Flue Gas Desulphurisation)process involving very high throughputs, very fi ne product sizes and high availability.Some companies in the mining industry also looked at the use of such optimised grinding machinesseveral years ago and found that many of the advantages offered in other industries are transferableto new applications.Much development work has been undertaken to improve the TowerMill for new applications and,as part of that work, tests have also been conducted to make direct comparisons of their performancewith that of ball mills. Grinding tests were performed using the same raw materials and comparablemachine sizes. Some of the results are discussed in this paper, along with a comparison of theadvantages and disadvantages. The conclusion provides an outlook for some worthwhile futureapplications.The test results, which are described and analysed, show that the TowerMill offers signifi cantadvantages in relation to operating costs and operational safety. An example based on the wetgrinding of limestone is presented. Source

This paper deals with the agglomeration process in a high-shear mixer. High-shear mixers rotate with a very high mixing tool speed such that not only a mixing effect, but also a grinding effect is achieved. The parameter study reported here was carried out to determine the parameters influencing mixing agglomeration. The results will help the user to decide which parameters have to be considered for an optimum mixing agglomeration. This article will highlight some of the findings obtained from the comprehensive parameter study. © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. Source

The compulsory mixers for concrete usual in the market can be divided into two groups. Each group has its qualifications, one for large quantities of standard concrete and the other one for concretes with high quality requirements. Source

Maschinenfabrik Gustav Eirich GmbH und Co. KG in Hardheim, Germany, has for a long time been a world market leader in mixing technology, including for the processing of dry building materials. Its global establishment with subsidiaries in America, Asia and Eastern Europe means that it is also successfully commissioning turnkey premixed dry mortar plants outside Europe. Handling the contract on site, establishing the strategy and general planning in the head office in Hardheim, supplying the key components from Germany and completing the plant engineering using local suppliers is an approach that clients find convincing. A production plant for coloured and fibrous plastering mortars in Albuquerque in the state of New Mexico, USA was handed over to the operator after successful commissioning in September 2009. The production location belongs to the Parex Group, which has its head office in Paris and has been operating in North America for about 20 years. During the course of extended re-alignment with the market the processing plant in Albuquerque, which was over 40 years old, was replaced by state-of-the-art storage, metering, weighing and mixing technology. Thanks to the Eirich RV15 intensive mixer together with the associated metering and weighing technology the plant is able to provide a production throughput of 20 t/h. The new processing plant, which was built with an in-line configuration, handles a variety of sands, cements, lime, fibres, additions, admixtures and different pigments. This article describes the general and detailed strategies employed for this turnkey plant. Source

The Maschinenfabrik Gustav Eirich GmbH & Co KG, located in Hardheim, Germany, is one of the global leaders in mixing technology, among other things in the field of processing systems for dry building materials. Over the last four decades the company has delivered over 230 mixers and mixing plants worldwide in this field. Just recently another new production plant for a wide variety of dry mortar products was successfully taken into operation in the United Arab Emirates. In this case, special attention was given to a customer-specific system configuration down to the last detail. The company called Top Concrete Products, located in Al Dhaid, Sharja, is already well known in the building industry and has extended its scope of supply with this new dry mortar plant. A short technical description is given in the contribution. Source
