  • Patent number: 10618087
    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.

  • Publication number: 20100252395
    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.

  • Patent number: 7073432
    Abstract: A method for binding logging waste or small timber material by using an automatic binding device, wherein the material is collected in a continuous bundle of brushwood and fed in the longitudinal direction. The material of the bundle of brushwood is compressed further in the binding device by tensioning the band which is fed in a continuous manner around the bundle of brushwood, and the band is finally locked as a strap which keeps the bundle of brushwood together.

  • Patent number: 6443197
    Abstract: A sawing device and a chain for it, comprising at least two adjacent sequences of connecting links, of which at least some are cutting teeth; and a sequence of drive links fitted between two adjacent connecting link sequences, wherein an opening at the rear end of the drive link is centered at an opening in the front end of the connecting links, wherein an opening in the front end of the drive link is centered at an opening of the rear end of the connecting links, and wherein a binding pin extending through the whole width of the chain is fitted in the openings. To increase the sawing width, a bush ring is fitted between two adjacent connecting link sequences, around the pin, and placed in the opening of the drive link, and on at least one side of said drive link, a collar is fitted whose diameter is formed greater than the opening in said drive link.

  • Patent number: 5735325
    Abstract: A tree feeding device of a tree handling machine has a saw (8) for cross-cutting of a tree trunk, a conveying unit (2) for moving the tree trunk, an actuator (4) for positioning the conveying unit (2) as well as delimbing blades (6) for delimbing the tree trunk. The conveying unit (2) has a rotatable structure with peripheral, substantially rigid surface adapted to support a continuous contact member, which transmits force between the rotatable structure and the tree trunk. The force acting between the rotatable structure and the tree trunk is adapted to be transmitted directly between the peripheral surface and the continuous contact member of elastic material, which is in direct contact with the peripheral surface and capable of moving freely in relation thereto in a manner determined by the load acting on the elastic material.
