RHEWUM: Dust explosions and the disastrous consequences

Published by

A dust explosion can have devastating consequences. Especially in the USA, the number of grain dust explosions in 2018 increased by more than 70% compared to the previous year.

When a dust explosion occurs, entire production facilities are usually destroyed. What remains are expensive damages, injuries or even fatalities. In 2017 the number of grain dust explosions in the USA was only 7. In 2018 the number increased up to 12

In a dust explosion the particle size is critical; the explosive potential increases with decreasing size. Size reduction results in very large surfaces, whereby the dust particles oxidise very quickly on the one hand and absorb ambient heat very well on the other hand and can ignite themselves.


In order to avoid such devastating dust explosions, it is very important to keep the screening plant dust-free, to ensure that the staff on site is well trained and that the equipment is properly maintained and in perfect condition.

RHEWUM’s screening machines with static housing are work for this purpose. Due to the static housing, failure-prone flexible connections, which are often the cause of dust contamination of the plant, are eliminated. The company’s machines are designed and manufactured in strict compliance with ATEX guidelines.
