Fixed, automatically activated misting system
This curtain misting system, which we installed on a trommel screen for the compost sector, has particular and highly customised features.
During our site inspection, we identified several dust emission problems. When loading the feed hopper, the loader released the material, raising a cloud of fine dust that spread across the site.
In addition, once the material had been screened and discharged into the bays below, the loaders used to pick up the resulting product generated new dust.
That is why we designed a system that acted on both zones independently at the same time.
On the hopper we installed a misting line with a presence-sensor activation system, so that it is only triggered when needed, that is, only when the loader is present.
A second “L”-shaped misting line was then installed to cover the area of the heaps produced by the screen, creating a barrier able to hold back the dust raised when the material is moved with loaders.
Operational and health benefits of misting on the screen
Water mist treatment offers real advantages:
Reduction of fine dust, protecting operators' health
Less odour dispersion, especially in composting processes
Greater visibility of the material, improving efficiency and safety
Compliance with environmental standards, mitigating the impact on the surrounding area
An effective system that is simple to integrate into the compost screening cycle.
Targeted misting on the rotary screen in composting
In the compost screening process, the moving material generates large amounts of dust, which can spread into the working environment. Installing a targeted misting system, positioned above the rotary screen, creates a fine mist that brings down suspended particles, improving visibility and operating conditions.
