Pellet production plants are characterised by the continuous handling of materials, with the consequent development of dust.
Various drums, belts and augers are fitted with specially shaped grasps, which is also the case for dryers which emit humid material that is pre-treated, using cyclones.
Remaining parts send the flow directly to a bag filter with compressed air counter flow washing, sized and compliant with the Atex regulation: overpressure relief valve, bursting panels, automatic discharge valves,  smokestack particle detectors, etc.. A high energy saving fan with coupling joint transmission maintains suitable in line pressure.
