MATERIALS HANDLING
industries and types of plants: from agriculture to powder metallurgy and steel production to the textile, pharmaceutical and food industries. Te optimal version for a
company’s individual requirements depends on many parameters, such as the thickness of the sheet metal, the material and diameter of the container or the drum, as well as the operating temperature. Te singold gerätetechnik service team advises on the selection of the ideally suited knocker and is happy to work out completely new application possibilities with creative application engineers.
KNOCKING ONLY OCCURS WHEN NEEDED Compared with conventional ball housings, for example, the Distance- Knocker QJ produces about 20 times the impact energy. Another advantage of the distance knocker is that while ball housings cannot be switched off when the drum is rotating, the QJ knocks on demand – i.e. only when it is needed for the process. Tis also benefits sound
The distance knocker can be used in a variety of applications
insulation and thus employee health. Te distance knocker is available in
different sizes. Te bridged distance to the element to be knocked off varies between 25mm and 35mm. In addition, the piston rod is available in an extended version that can increase the distance of the knocker to the container by another 200mm. In the case of very hot walls in particular, it is necessary to set the distance between the knocker and the container as high as possible. Te temperature of a knocker should not exceed 140°C because otherwise the seals and other parts would wear out too quickly.
As sophisticated as the invention of Erwin Lüer is, it is nevertheless simple in
construction. What this means for the end user is that the Distance-Knocker QJ proves to be a low-maintenance tool in operation. Should a component ever need to be replaced, the knocker is simply disassembled and quickly reassembled.
