Since October 2009, the former Humboldt Wedag Coal & Minerals Technology GmbH has been part of McNally Bharat Engineering Company Ltd. (AT INTERNATIONAL reported in its 03/2010 edition, see p. 33). Despite its new name, MBE has remained true to its customers in its products. This was the background for an interview between a young face and the AT INTERNATIONAL editorial team concerning a well-known and proven product. Dipl.-Ing.

AT INTERNATIONAL: What applications are especially suitable for the PALLA® vibrating mill range of products (see information box)? Menninger: These mills are particularly suitable for fine and ultra-fine comminution of materials with extremely differing properties, ranging from soft to extremely hard products. But the PALLA® is also suitable for activation, densification and homogenisation processes. Vibrating mills are used, just for example, in the mineral resources and refractories industries, in the chemicals industry, and for grinding in the ceramics, dyestuff and glass industries. The needs of the various branches necessitate a versatile and variable vibrating mill concept; variants include dry and wet grinding, continuous and discontinuous grinding processes, indirect...
