Problems solved by technology
[0003] Now the mining industry needs to use a lot of machinery and equipment, among which the grading and screening process is the most important. Its function is to classify and screen the crushed ore and silt, but now many wet silt groups are easy to block the sieve holes. Difficult, and many of the sediment impurities make it difficult to classify and cannot meet the current use requirements

The invention discloses a spiral grading device. The spiral grading device comprises an upper box body and a lower box body; spiral discharging blades are arranged in both the upper box body and the lower box body, and are connected with a transmission though a rotating shaft; a driving motor is installed on the transmission; the upper box body and the lower box body are arranged in an up-down inclined manner; the lower end of the bottom of the upper box body is connected with a primary sedimentation box through a primary filter screen; the middle segment position of the bottom of the upper box body is provided with a secondary filter screen; the lower box body is arranged below the secondary filter screen; and the lower end of the bottom of the lower box body is connected with a secondary sedimentation box through a third-level filter screen. The spiral grading device is novel in structure, stable in running, capable of achieving integrated machining of tossing and grading for the mining industry, saving energy and protecting the environment, small in discharge capacity, and capable of meeting the current using requirements.
Description
technical field [0001] The invention relates to mining equipment, in particular to a spiral classifying device. Background technique [0002] Mineral dressing is based on 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. A process in which symbiotic (associated) useful minerals are separated from each other as much as possible to remove or reduce harmful impurities to obtain raw materials for smelting or other industries. Mineral dressing can enrich useful components in minerals, reduce fuel and transportation consumption in smelting or other processing, and enable low-grade ores to be economically utilized. The data obtained from the beneficiation test is the main basis for the evaluation of ore deposits and the design of plant construction. [0003] Now the mining industr...
