Explosion protection with MOLOSroto from MOLLET

MOLOSroto rotary paddles avoid explosions even in very dusty environments!

Even it is difficult to imagine, working in such an environment is life threatening. Dust is able to explode! The reasons for that are the increased reactivity and the lower thermal conductivity due to the large specific surface area. For example a fire ball with more than 15 m in diameter arises, if only 1.5 kg of pulverised lignite is detonated by a spark. But what might dust mean? Dust consists of smallest, finely divided solid particles of any shape, structure and density with a particle size of less than 0.5 mm that sediment due to the self-weight but although remain airborne as a dust/air mix for a time.

MOLOSroto rotary paddles with the required approvals avoid explosions even in very dusty environments. The explosion protection required for that is achieved by the ignition protection category “t” and “c”. In order to provide the type of explosion protection “t“, the protection is based on the use of dust proofed and dust tight housings with a limitation of the surface temperature of the device below the glow temperature of the occurring dust. The devices have to be designed according to procedures of IEC/EN 60079-0 with stricter mechanical testing e.g. for good thermal and impact resistance. In order to provide the type of explosion protection “c“, mechanical generated sparks and electrostatic charges have to be avoided and suitable constructional parameters and safety distances have to be selected. MOLOSroto level indicators with high-quality components, sealed bearings and a wide range of additional options are therefore the ideal solution for level control of bulk solids in dusty environments.

Explosion protection made by MOLLET
Level measurement in explosive atmospheres requires know-how provided by MOLLET Before level measurement in a potentially explosive atmosphere could be operated the potential risk of explosion has to be evaluated in a risk assessment. Part of this is the evaluation of the formation of explosive atmospheres. This will occur only, if atmospheric oxygen in sufficient quantities, an effective ignition source and combustible material appear at the same place. Combustible material could be flammable dust, gas and hybrid mixtures. Flammable dust means dust, fibers or suspended particles which can burn or glow in the air and could explode in atmospheric conditions. Products like coal dust, aluminium powder, powdered sugar, wheat flour or dust caused by grain are included. These dusts occur permanently by transportation, filling and discharging of bulk solids and are often been spread over the entire premises. Depending on the danger of explosion the premises is classified into different potentially explosive atmospheres according to the ATEX guidelines.

MOLOSroto – Rotary paddle Reliable all-rounder for level measurement in bulk solids
MOLOSroto – Rotary paddle
Reliable all-rounder for level measurement in bulk solids The rotary paddle switches of the MOLOSroto series are the ideal solution for level monitoring in the areas of storage, processing and transportation. Fine powders of the pharmaceutical industry can be reliably measured as well as sand and coarse gravel for the building material industry or plastic granular or wood pellets. In order to match this extensive scope of tasks the MOLOSroto devices are provided in thirteen different basic versions. One of them is the MOLOSroto DF21 that is characterized by a wide range of applications. The MOLOSroto DF23 with reinforced blade shaft is even more robust than the DF21. Many other sensors require an additional protective roof within large silos, as significant forces impact on the sensors for empty detection. With the MOLOSroto DF25 it is a different story; the DF25 is equipped with an angled jib, a protection tube made of stainless steel, reinforcement rips and a solid flange; therefore it reliably monitors the empty level
