A tool for dry mixing and coating of powder mixtures comprising includes a fixing shaft and an approximately disc-shaped element fixed thereto and of a diameter d, having an upper surface, a lower surface and a peripheral surface connecting the upper and lower surfaces. The disc-shaped element has a plurality of grooves extending parallel to the shaft axis. Each groove has two groove walls extending from the peripheral surface to a groove bottom. A tooth is formed between two grooves. In order to provide a tool which is suitable for particularly low contamination dry mixing, dry dispersing and coating of powder mixtures, the disc-shaped element has a base portion and at least one wear element fixed to the base portion, wherein at least one portion of each groove wall, that adjoins the peripheral surface, is formed by the wear element.

A compost turning apparatus mountable on a loader for turning composting materials may include a mobile base having a frame with inboard, outboard, and bridging portions defining a windrow tunnel through which a windrow of composting materials are passed. The inboard portion may be configured to mount on the loader. The apparatus may include a rotor extending across the windrow tunnel, and the rotor may include a rotor shaft and paddles on the rotor shaft. A rotor drive assembly on the mobile base may rotate the rotor using a motor hydraulically-connectable to a hydraulic power system of the loader.
