When grinding metal and non-metal materials the dust is spread in all directions into production halls and attacts not only grinders but also other workers. Besides the negative influence on the workers´health by inspiring of dust particles, the risk of explosion at higher concentrations arises. Therefore, when implementing the extraction system, it is neccessary to ensure that the equipment meets the conditions of the ATEX directive.
The ATEX directive defines the claims on security and health protection of the employees working in a potentialy explosive environment as well as the technical claims on equipment placed in the environment with the danger of explosion..
