Description

Ore sieve separator is used in mine Technical Field The utility model relates to the technical field of ore screening, in particular to an ore screening machine for mines. Background The ore is a mineral aggregate from which useful components can be extracted or which has certain utilizable property, and can be classified into metal minerals and nonmetal minerals, raw ores mined by mines are often different in size and complex in composition, and can be further processed by effective screening, and the ore screening machine is an auxiliary device for screening coarse and fine ores. Meanwhile, the traditional ore screening machine directly impacts the screen plate after the ore enters the screening equipment from the feed inlet, so that the screen plate is greatly worn, the service life of the screen plate is shortened, and the ore is easily accumulated in a local area of the screen plate under the conditions of no buffering and guiding, thereby influencing the uniformity and fluency of screening.
