The processing of graphite materials by turning, milling, drilling or grinding during metalworking generates fine dust inside the work area. This dust can permeate machinery, the workplace, and the surrounding environment. High efficiency dust separation systems are required to prevent potential health risks and to adhere to regulatory guidelines in the management of graphite dust, as well as to increase machinery effectiveness and reliability.
Dry separators of the L-CUT and VARIO series are suitable for the extraction of graphite dust from machine tools.
The capture elements are optimally adapted to the function of the machine tool and to the travel paths of the axes.
Besides an ignition source-free design, a spark pre-separator can further reduce the fire risk.
Graphite dusts are often categorized into St1 dusts (explosive dusts). In most of the cases is the minimum ignition energy so high, that explosion protection measures can omit.
