Impact crusher in copper ore production maintenance

After the copper processing equipment, the impact crusher can be used as a third step processing equipment, after jaw crusher big stone, then back-breaking, and again after broken into customer needs 20 ~ 60mm particles. Crusher is able to break the mechanical advantage of a shock. To ensure the back-breaking, better run continuously in copper processing equipment, the continuation of the life of back-breaking, back-breaking user should perform regular maintenance and upkeep. After the new machine in operation, when the work is completed in each class must be back-breaking conduct a comprehensive inspection. After a week of back-breaking run motor lubrication conduct a comprehensive inspection. Check the contents include a fixed part of the fastening, belt drive, bearing seals, back liner, liner wear a full range of inspection, combined with the establishment of a regular maintenance cycle maintenance and replacement system. Copper processing equipment operating time between the device and the device will cause friction between the equipment and raw materials, so the degree of wear of the equipment is not the same. Copper ore beneficiation basic flotation-based, single-sulfide copper ore flotation process in general is relatively simple, only grinding - the flotation structure is different and complex sulphide copper ore, here is a paragraph grinding - flotation - rougher concentrate regrinding process. Factors affecting the recovery of copper ore beneficiation main ore mineral composition, the number of mineral particle size, structure, useful and harmful components of its occurrence, the degree of oxidation and beneficiation process and the percentage of various minerals, ores the level of equipment and so on. Here are a few copper processing equipment effective way to improve the recovery of copper ore beneficiation.

Impact crusher rotor and counterattack liner gap adjustment: When the rotor back-breaking run, the gap between the rotor and the back liner can not be adjusted. As the material into blocks stranded in between the back plate and the plates and shells, it is recommended to re-adjust the gap between the slightly raised back rack, feed this into the block becomes loose, back rack is easy to adjust. If sufficient enough to stand back, pat (with a piece of wood protection) can relax on the rod, the gap between the rotor and counterattack liner machine by adjusting the device to complete, first loosen the set screw, and then rotate the long nut, then the rod will be upward direction, adjust fortunately will cover tightened. Crusher replacement of wearing parts: When the back-breaking replacement of wearing parts, after first open shelves. When in use, the first after the shelves in the cabinet and remove the coupling bolts, and then use a wrench to tighten the hex head portion of the clamshell device, and then slowly open shelves. At the same time, can be used hanging device Diaozhu rear frame above the racks. Repeat the above process, that after closing the shelves. Large-scale equipment is one of the main measures to improve the technical and economic indicators of the copper concentrator. Concentrator To use a large-scale construction equipment and adapt itself, which is conducive as possible to achieve the production of automatic control and improve the recovery of copper ore, reduce energy consumption and costs, improve economic efficiency concentrator. Copper concentrator chain control system can be crushing, grinding system is a constant proportion of water to the mine automatic control, level control flotation, pulp pH control, fluorescence line analysis and computer monitors, computer administration, intelligent automation control measures and equipment to improve mineral recovery.
