Embodiment

[0022] Example: In Yunxi Datun Concentrator, the newly built 8,000-ton / process second-stage bed implemented the automatic process parameters and equipment intelligent monitoring and control of Yunxi shaker beneficiation.

[0023] (1) Concentration and volume of ore feeding to Yuntin shaker; range of rough, fine, and engraved shaker times (rotation speed); shaker slope, flushing water, pick-up position of concentrate belts of different grades, etc. parameter setting.

[0024] (2) The optimum ore concentration, ore feeding volume, and the range of rough, fine, and engraved shaking times for different ore properties in the old Yunxi factory, Kafang, and Tuen dressing (pine ore) areas. ; Shaker slope; Rinse water; Testing of the pick-up position of concentrate belts with different tin grades, etc., to determine the best shaking table sorting process parameters, and submit it to the automation control profession.

[0025] (3) Through the automatic control of the specific gravity c...

Abstract

The invention relates to a method for automatically monitoring tin ore table beneficiation, and belongs to the technical field of nonferrous metal ore beneficiation automation. The method includes the steps that the table feeding concentration and the table feeding volume are automatically controlled through automatic control over water adding and control flow of a specific gravity concentration meter, a flow meter and linkage control valves; ranges of the coarse sand table jig frequency, the fine sand table jig frequency and a groove carving table jig frequency are controlled through frequency modulation control over a table motor by PLC programming; the optimal washing water flow is controlled in the modes that monitoring is carried out through an automatic camera shooting module, and an adjustment valve is controlled by a PLC; the optimal table body gradient is controlled in the modes that monitoring is carried out through the automatic camera shooting module, and a mechanical component is driven by the PLC and a single shaft control servo motor; the tin concentrate receiving position is controlled in the modes that monitoring is carried out through the automatic camera shooting module, and a mechanical component is driven by the PLC. According to the method, it can be guaranteed that the table feeding concentration and the table feeding volume are stabilized to be in the optimal states, the grading index can be improved, and the labor cost can be greatly reduced.

Description

technical field [0001] The invention relates to an automatic process parameter and equipment intelligent monitoring and control method for mineral processing of a cloud-tin shaker, belonging to the technical field of mineral processing automation of non-ferrous metal ore. Background technique [0002] The shaking table is the main sorting equipment for gravity separation and recovery of heavy minerals. Its operating parameters such as ore feeding concentration, volume, flushing times, concentrate flushing water, and bed slope are mainly determined by the operator according to the nature of the ore and the ore belt of the bed. The distribution phenomenon is adjusted manually. Therefore, the labor cost of the gravity separation plant with the shaking table as the main gravity separation equipment is relatively high (about 70% of the total cost of beneficiation). Secondly, manual operation cannot ensure the accuracy of the ore feeding concentration and ore feeding volume of the...
