Abstract
Device (1) and method for dosing an aqueous solution (2) of an additive, e.g., a non-caking agent, into an amount of a particulate material, such as a salt. The device comprises a conveyor (4) for transporting the particulate material and a dispenser (5) arranged above the conveyor. The dispenser is connected to a supply for the aqueous solution. The dispenser comprises a pouring outlet (10) extending over at least a part of the width of the conveyor (4). The additive solution is poured with a controlled flow velocity over at least a part of the width of the conveyor (4) transporting the particulate material.
Claims18
A device for dosing an aqueous solution of an additive onto an amount of a particulate material, the device comprising a conveyor for transporting the particulate material and one or more dispensers arranged above the conveyor mounted on a frame, the one or more dispensers suspended and pivotably supported on the frame by a first pivoted support supported by a second pivoted support with two pivot axes being orthogonal, wherein the one or more dispensers are connected to a supply for the aqueous solution of the additive, the one or more dispensers comprising a weir, and wherein the one or more dispensers comprise at least one pouring outlet extending over the width of the conveyor, wherein the pouring outlet
- (a) is formed by a row of gutters slanting downwardly at an angle from the horizontal, and
- (b) is adapted to dose the aqueous solution onto the particulate matter solely by gravity.
