<p>A device for discharging particulate materials, especially when wet and in specific quantities, allows uniform discharging across the cross section of a container through a number of ports in the floor of the container. A device underneath and at a distance from the ports is such that it exhibits plates having nozzles connected to an air or liquid supply under pressure and the application of the said device allows control of the formation of a cone of material whereby the discharging process can be easily controlled and stopped as desired.</p> |
