The raw ore is crushed in the first stage and then screened in double-deck vibrating screen, the upper product is crushed again and then crushed in the second stage together with the middle product, the second crushed product is returned and combined with the first crushed product to be screened again.
After screening, the final product will be milled in the first section ball mill and constitute a closed-circuit milling with the classifier, and its classification overflow will be classified by the cyclone and then enter the second section ball mill for regrinding, and then constitute a closed-circuit milling with the cyclone.
The cyclone overflow firstly undergoes priority flotation, and its foam product undergoes secondary and tertiary selection to finally become the concentrate product, and the tailings after priority flotation undergoes the separation process of primary roughing, primary selection, secondary selection, tertiary selection and primary sweeping, and the tailings of primary selection and the foam product of primary sweeping enter into the cyclone for re-grading and re-selection, and the secondary selection and primary selection constitute the closed-circuit separation. The third selection and the second selection constitute a closed-circuit sorting.
Brief introduction of shaking table gold beneficiation method in gold ore dressing equipment
Shaking table gold separation method
Shaking table gold beneficiation is a gold beneficiation process with shaking table as the main equipment. Shaking table is in the horizontal media flow for ore dressing equipment, by the bed and transmission mechanism composed of two parts, the bed by the transmission mechanism with action longitudinal reciprocating motion. Ore in the shaking bed sorting is in the bed reciprocating movement process is completed gradually. Factors contributing to the movement of the ore particles, in addition to their own gravity, mainly is the impulse flow and bed surface differential motion. Ore particles in motion perpendicular to the bed stratification and parallel to the bed separation. The result of the two roles is different ore particles from the bed surface of the different zones of discharge.
Shaking table according to the selection of other ore particle size, can be divided into coarse sand bed (> 0.5 mm), fine sand bed (0.5 ~ 0.074 mm) and sludge bed (0.074 ~ 0.037 mm) three kinds.
Maintenance of gold ore dressing equipment:
First of all, it should be inspected regularly in the process of use, and the inspection results should be recorded. And also the daily use, the workload of the daily record should be recorded. Conveniently, if there is a problem in the future, you can check the record to find out the record, and find the best solution. In addition, to avoid collision, keep the machine clean, do not cooperate with corrosive substances.
Secondly, the injection of lubricant should be clean, in addition to good sealing, lubricant to a large extent also determines the operation rate of the machine.
