The invention concerns a mobile processing device having a material processing unit, such as a mobile crusher having a crusher unit or a mobile screen having a material screening unit. The mobile processing device comprises a power unit, a frame and a noise encapsulation for the material processing unit. The noise encapsulation is attached to the frame and comprises two cover elements, each of which is pivotable between an open position providing access to the crusher unit and a closed position wherein the cover elements can be interconnected to create an encapsulation for the material processing unit.

A stockhouse arrangement for a metallurgical furnace includes a set of storage bins for granular material; a material feeding device associated with the set of storage bins, the material feeding device being arranged above the set of storage bins and allowing to selectively fill each of the storage bins with granular material; and a raw material feed system to convey raw granular material to the material feeding device, wherein a respective weighing hopper is arranged downstream of each storage bin and including an outlet associated with a feeding gate. A and a charge conveying system is provided for collecting and conveying material selectively discharged from the weighing hoppers through their respective feeding gate, the material feeding device being configured to screen raw granular material arriving from the raw material feed system such that only material with desired granulometry is forwarded to the respective bin(s).

Screening machine (10) for screening solid materials, comprising both a screening box (12) shaped so as to have a plurality of perimeter walls (16, 17, 19, 21) and an upper wall (15), and configured to make said solid materials to be screened flow inside it, and also a plurality of anti-propagation devices (27), at least a first of which is disposed on said upper wall (15).
