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.

Abstract: A leg and a method for measuring the position of a leg for a processing device, which leg comprises a first transfer member, which is articulated to the processing device and a second and a third transfer member for changing the position of the leg. The leg further comprises at least one measuring means for measuring the position of the leg in relation to the processing device.

Abstract: A method for moving a processing device, a frame of a processing device and a processing device, which is moved on a base. The processing device comprises at least one processing unit and a frame, to which the processing unit is attached, as well as at least four legs articulated to the frame. The legs comprise support plates settable against the base. The legs are settable into a support phase, where the support plate settles against the base and into a transfer phase, where the support plate is off the base. The processing device is moved without lowering the frame onto the base so that the legs are controlled to settle to the support phase and the transfer phase alternately so that at least three legs are in the support phase when the processing device moves.
