Abstract
A system for recovering antifreeze from a dust prevention system of a mineral material processing plant, wherein the system includes an antifreeze tank, a pump configured to circulate water and/or antifreeze, a first valve configured to connect to a water inlet and/or antifreeze tank to the pump, a nozzle manifold connected to the pump, a second valve configured to connect the nozzle manifold to the antifreeze tank and/or a third valve, and a control system. The control system is configured to operate the system according to a method including the steps of sucking water using a pump from a water inlet via a first valve, displacing the antifreeze via a nozzle manifold into an antifreeze tank until the water reaches a second valve, and connecting the second valve to a third valve to allow circulation of water in the system.
