How does foam dust suppression work?
The majority of dust in a typical quarry is created during the extraction and crushing process. Dependent upon the nature of the mineral, moisture content and particle sizes – the dust is released in to the environment during subsequent conveying, screening, stacking and loading operations.
In order to prevent dust particles from getting airborne Foam is introduced in controlled measures immediately prior to the crusher and directly in to the crushers. This ensures that all the material is fully coated in Foam.
As the mineral / aggregate is crushed – new faces are exposed and dust particles are released. These dust particles collide with the Foam bubbles piercing and thus releasing the moisture held therein. The result is that the dust particle becomes thoroughly wetted and its increased weight causes it to fall back on to the main body of the material. The wetted dust particles will then continue their entire journey through subsequent crushing, screening etc to the final storage bins without ever getting airborne.
To achieve effective dust suppression approximately 2 litres of solution converted to Foam is required per one tonne of material. ODS Foam has been developed to bind dust and floating parts. ODS Foam totally biologically degradable so it can be used on many applications.
The Rino is the new Fog maker machine from Idrotech to help in the fight against dust problems. Used in the quarry, demolition and mining industries it has proven to be a great success. Designed to maximise the water flow to produce maximum droplets.
The Rino is one of several models, Elefante and Giraffe help to compliment and offers an option of moving to larger units. All these units come wit low pressure or high pressure options, automatic running and oscillation. Electric controls are fitted in stainless steel cabinets giving quality at below market prices.
We are now able to offer several pieces of equipment to assist in bring down dust droplets while demotion is in progress. We can offer a small petrol driven or 110v electric driven 18 inch fan unit. Easily connected on site and one person can remove at night to stop theft.
Our mobile atomiser where we can set at the crusher or near to the area of demolition. Ideal for asbestos fibres.
