Abstract

The invention discloses a screening device capable of conveniently crushing and screening mineral raw materials. The screening device comprises a box body, a vertical bar and grinding tables. A material hopper is arranged above the box body, a crushing block is arranged below the material hopper, and the crushing block is arranged in the box body. Protruded blocks are fixed on the inner side of abearing. Loop bars are fixedly arranged on the inner sides of third gears and the loop bars are arranged below screening buckets. The screening buckets are provided with grinding ribs and screening holes. The grinding tables are arranged on the inner sides of the screening buckets, penetrate through the loop bars, and are fixedly connected with the box body. A discharging outlet is formed below the box body. According to the screening device capable of conveniently crushing and screening mineral raw materials, crushing processing is conveniently carried out on the hard mineral raw materials, rotating grinding and extruding grinding are carried out simultaneously, so that the crushing method is more abundant, the crushing effect of the mineral raw materials is improved, the need of multiplecrushing and grinding is avoided, and the beneficiation flowsheet is simplified.

Description

technical field

[0001] The invention relates to the technical field of mineral processing equipment, in particular to a screening device for conveniently crushing and screening mineral raw materials. Background technique

[0002] Mineral beneficiation means that according to the physical and chemical properties of different minerals in the ore, after the ore is crushed and ground, gravity separation, flotation, magnetic separation, electric separation, etc. are used to separate the useful minerals from the gangue minerals. It is the process of separating the useful minerals that are symbiotic (associated) from each other as much as possible, removing or reducing harmful impurities, and obtaining the raw materials required for smelting or other industries. The beneficiation process is mainly composed of two basic parts: dissociation and separation. The most important link in the production process of the product can enrich the useful components in the mineral, reduce the cons...
