Foaming system targets dust around conveyors and crushers

June 1, 2018

Dust suppressing chemicals company Reynolds Soil Technologies (RST Solutions) has released a mechanical foam dispensing system and Hi-Foam product.

The mechanical foaming system mixes compressed air, water and the Hi-Foam chemical. When applied, the foam captures and engulfs fine particles in a ‘dust blanket’ that aims to prevent dust from becoming airborne.

RST Solutions operations and technical director David Handel said its technicians worked closely with customers to design and install the mechanical foaming systems on a case by case basis, assessing the site’s individual needs for best results.

“Each site installation of our foaming system system is unique – we work with the site to understand its dust suppressant needs and design the application equipment for our product accordingly,” he said.

“Our Hi-Foam foaming system is popular with conveying and crushing operations where moisture limitations on materials is critical, as the system effectively produces a dust suppressing foam that treats large areas with minimal water and dosage requirements.

“When applied, the foam wets dust particles to increase their weight, causing them to continue their journey through the conveying and crushing system without ever becoming airborne.

“The way in which a product is applied to a site can significantly impact performance, that’s why being able to design and customise both the product and the application is important.”

The foaming system utilises a dosing feeder that injects the additive directly into the system’s water line, allowing for the manual concentration adjustment of the solution.

The air and water then mix in an expansion chamber capable of supplying a dust suppressing foam to six dosing points introduced at specific stages in the crushing and conveying circuit.
