Dual fluid atomizer for high solids soil paste containing pebbles or agglomerates

An atomizer for atomizing a material having a high content of solid particles, the atomizer comprising:

• an inner conduit for channeling a flow of the material;
• an outer conduit surrounding the inner conduit, the outer conduit and the inner conduit defining an annular space therebetween, the outer conduit for channeling a flow of air in the space;
• the inner conduit and the outer conduit forming a discharge end;
• discharge means at the discharge end of the inner conduit and the outer conduit for discharging an atomized spray which includes the air flow and the material flow, the discharge means being made of a wear-resistant and high temperature-resistant material;
• and
• means for channeling the air flow into the material flow at the discharge end for creating the atomized spray, the discharge means including a first wall, a second wall and a third wall, the first wall being connected to the second wall and the second wall being connected to the third wall, also the first wall, the second wall, the third wall and the means for channeling the air flow into the material flow defining an opening therebetween, the atomized spray being discharged through the opening.
