MINING SIFTER, SCREEN MOUNTED ON A MINING SIFTER, MINING SYSTEM AND METHOD FOR CONTROLLING A MINING SIFTER

摘要

A mining sifter (100) is described, comprising at least one propulsion element (140) associated with a sifting structure (165), wherein the mining sifter (100) can implement (develop) at least one vibration mode of operation in which the sifting of a material moving on the sifter (100) is increased, the sifter (100) being so designed that at least either the propulsion element (140) or the sifting structure (165) is produced from a first material, the first material being a composite material (composite). Also described is a screen (156) mounted on a mining sifter (100), a method for controlling a mining sifter and a mining system.
