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.

Method and system for recovering antifreeze from a dust prevention system of a mineral material processing plant

A mineral material processing plant and a method for controlling thereof. The mineral material processing plant includes at least one motor, at least one actuator, a feeder device, a control system, and an arrangement for recognizing a need to switch off a standby-mode. The control system is configured to control the processing plant in such a way that the need to switch off a standby mode is automatically recognized. In response to the recognized need to switch off the standby mode the running speed of a motor or motors of the mineral material processing plant is raised from a stand-by speed (Rsb) to a process speed (Rf); and the feeding of mineral material into the processing plant is enabled.
