The main points of technology implementation in the process of reformation of beneficiation machinery
The key to improving the production efficiency of mining enterprises is to resolutely implement technological transformation and equipment update. Today’s development of science and technology is no longer the era of improving production efficiency by relying on traditional methods of mechanical overload operation. The production quantity has increased the overdraft loss of the life of the beneficiation machinery, and in the sense of the overall production, it has reduced the production effect. 1. Transformation of beneficiation machinery and equipment    The 12m single-layer thickener in the existing beneficiation machinery is not equipped with a corresponding buffer gas tank, and the mine station is not equipped with a wage barrel and a diffuser under the barrel, etc., resulting in unstable operation of the thickener during work. These problems can be solved by effective technical transformation and reasonable configuration of production equipment. The beneficiation process in the beneficiation process must eliminate the outdated JJF-4 flotation machine, blow compressed air into the porous medium, and replace the slurry with an inflatable flotation machine that can be filled with air and stirred. This transformation method is beneficial to improve the beneficiation index, save the process cost, and facilitate the maintenance and management of the machine. For the phenomenon of snakes when the conveyor belt, the method of combining the conveyor belts of the crushing system with each other can be adopted; for the slipping phenomenon of the products conveyed by the conveyor, a long feed screw with an appropriate distance can be selected as the guide for the product conveying, and the crusher belt is required The transmission speed is reduced from 1.25m/ to 1m/s, and finally the conveyor belt width is increased again from the existing conditions to 800mm. Since the effect of thick-walled seamless steel pipes far exceeds that of broken vibrating sieve bone pipes, the use of thick-walled seamless steel pipes to eliminate the effect of broken vibrating sieve bone pipes has reduced the existing 7 stiffener plates to 3, and the stiffener plates The shape is changed to the shape of the trough, which can further increase the volume of the sorting, and improve the work efficiency and work intensity of the entire sorting process. 2. Improve and optimize production technical conditions Due to the low production efficiency, high circulating ore volume, most of the products produced by the crushing cone crusher do not meet the production requirements, more equipment must be equipped, and more complex equipment must be used to complete the work, which is not conducive to the improvement of production efficiency And improve. The data shows that the experiment proves that replacing the traditional cone crusher with HP300 cone crusher can greatly improve the production efficiency of the machine and the qualified rate of the product. This new type of crusher achieves the reduction of the particle size of the crushed product and the increase of the mill's pore size by more finely modifying the structure and size of the crushing chamber and reducing the diameter of the screen hole to achieve the initial individual separation of iron minerals.    In the aspect of flotation collector modification, the combination of quina xanthate and isopenu xanthate can effectively improve the hydrophobicity of iron minerals, which is beneficial to the separation of iron minerals. In addition, other modifications can also be made, such as using liquid sodium chloride instead of solid products, to make the specific operation process more concise and convenient, and to improve the reliability of production. In addition, liquid sodium chloride can reduce the amount of drugs added, save costs, and improve economic benefits. In order to optimize the control of the unloading of the thickener, an automatic unloading device can also be installed on the single-layer thickener during production in the mining area. 3. Optimize the production process   Optimizing the specific production process of the beneficiation process can promote the improvement of the work efficiency of the overall beneficiation machinery system. For example, technically recovering the water obtained from mine tailings as a raw material is used again in the production process to realize the recycling of industrial water, which not only achieves zero pollution and zero discharge of industrial wastewater in environmental protection, but also saves production costs and reduces Economic measures for production inputs.

How to use the beneficiation shaker
1. The bed surface division of the shaker    The bed surface is divided into concentrate area, middle mining area, tailings area and sludge area. Generally, the width of the mud area is 0.9~1.4m. The ore flow in the tailings area should be stable, and there should be no rapids or ravines. The thickness of the ore bed must be appropriate and must be covered with water. The tailings area can be controlled by adjusting the feed concentration and the sand hole of the feed trough. The middle mining area is the division of the middle mining area, which is mainly controlled by adjusting the scouring water and the lateral slope. The beneficiation area requires the separation zone of each specific gravity mineral to be obvious. In order to form a stable and obvious boundary between the beneficiation area and the primary selection area, the area is controlled by adjusting the scouring water and the lateral slope.   2, the horizontal and vertical slope of the floor of the shaker   When the equipment is installed, the longitudinal slope is determined, the coarse sand area is longitudinally inclined 1~2, the fine sand area is 0.5~1.0, and the ore mud area has basically no slope. The bed surface is inclined by 1.5~5 from the feeding end to the opposite side. In actual operation of the shaker, the vertical and horizontal slope of the shaker surface must be accurately controlled. Generally, when the mineral particles are relatively coarse, the lateral slope of the shaker floor should be appropriately increased. On the contrary, if the mineral particles are very fine, the slope of the ground needs to be lowered. Generally, the transverse slope ranges of coarse sand area, fine sand area and sludge area are 2.5~4.5, 1.5~3.5, and 1~2 respectively.   3, feed size    The particle size of the ore must be appropriate. The upper limit of the input particle size is 2~3mm, and the lower limit is 0.037mm. Generally speaking, classification in advance ensures uniform particle size at all levels, but in order to ensure that the particle size at all levels of the shaker is uniform and the particle size is within the appropriate range, it is necessary to observe the ore belt in the concentrate belt and check the tailings through ore washing.   4, the amount of ore    The size of the ore volume is related to the size of the raw material. When the ore grains are coarse, the required amount of ore feed becomes larger. However, if the amount of ore is too much, it will cause banding problems. In this case, it is necessary to move the concentrate cut-out board to increase the horizontal slope of the flushing water and the shaker surface. It should be noted that once an accurate feeding amount is found, it is necessary to continuously ensure the feeding process to maintain uniformity.   5, the concentration of the ore   In the screening process, it is necessary to ensure the proper concentration of the ore. Generally speaking, the feed concentration of coarse and fine-grained minerals is 20% ~ 30% and 15% ~ 25% respectively. When there is a groove problem on the rocking bed, the ore concentration can be appropriately increased to adjust; on the contrary, when sand hills appear, the ore concentration needs to be reduced at this time. The concentration of ore can be controlled by adjusting the amount of water supply.    6. Washing water   Flushing water includes mineral water and flushing water. When operating the shaker, when the concentrate belt becomes narrow and the concentrate rushes into the middle ore, the amount of flushing water needs to be reduced; on the contrary, when the floor of the shaker is exposed to anhydrous film, the amount of flushing water needs to be increased appropriately. To control the amount of washing water, it is necessary to carefully observe the slurry flow rate and the narrow width of the concentrate belt.
