The invention relates to an arrangement in a mobile machine for screeding floor surfaces. This comprises a housing with a planet disk (), which is rotatably supported in the bottom of the said housing and driven by a drive motor (). The planet disk carries a number of rotatably supported screeding disks, distributed over the planet disk () and operatively connected to the drive motor (). According to the invention the number of screeding disks is an even number up to a maximum of six. Viewed in the direction of rotation of the planet disk (), half the number of screeding disks have a direction of rotation coinciding with the planet disk () and the remaining screeding disks an opposing direction of rotation.

Arrangement in a mobile machine for screeding floor surfaces

A gyratory crusher comprises a body and an annular outer shell, which is fixedly connected to the body about an essentially vertical center axis. A shaft member is arranged radially inside the outer shell to perform, during crushing, a swinging movement about the center axis. A crushing chamber forms between the outer shell and an annual inner shell arranged on the shaft member. A piston member is displaceable along the center axis and is arranged in a cylinder member belonging to the body. The upper end of the piston member supports, via an intermediate thrust bearing, a lower end of the shaft member. A transport duct for supplying to the thrust bearing a medium promoting the bearing function extends through the piston member and is defined upstream of the piston member by a transfer means. At least a part of the transfer means is displaceable relative to the piston member and at least a part is displaceable relative to the cylinder member.
