Fluctuation machine spindle motor torque adjustment

Red Star Heavy Industries Co., Ltd. strives to contribute to the development of social economy by pursuing the idea of ​​not wasting resources on flotation equipment. Most people only saw the business opportunity for the development of slime flotation machines. Red Star Heavy Industry even looked at the significance of coal flotation machines for economic construction. The flotation channel agent control system can be used to control the slurry concentration within a reasonable range to obtain a large flotation rate.

Reasonably adjust the prescription, with particular attention to the amount of foaming agent. In general, adding a small amount of foaming agent will promote flotation speed. However, it must be noted that excessive foaming agents will reduce the selectivity. Therefore, in the case of fine selection and large collection doses, it should be noted that the amount of foaming agent should not be excessive. The higher the speed of the door opening, the lower the speed of the shutter opening is lower. According to the torque characteristics of the motor of this flotation device, the speed control method of FM is used for the spindle motor of an energy-saving slime flotation machine.

The situation in which the concentration of concentrate foam is depleted and the flotation speed is reduced is effectively avoided. The speed of flotation equipment is controlled based on the opening of the coal flotation machine's gate, the greater weight of light block machine high-speed coal slurry flotation machine, as the name suggests is a high flotation efficiency coal flotation machine, while The flotation index of high-speed flotation equipment is also higher than that of ordinary coal slurry flotation machines. Explain how high speed coal slime flotation machine can improve flotation efficiency.

Reducing the turbulence intensity of the ore slurry is the fundamental measure to ensure coarse-grained flotation. Improve and adjust the structure and operation of conventional slime flotation machines, shorten the floating path of mineralized air bubbles to avoid exfoliation of the minerals. Add grate sieves above the impeller area to reduce the turbulent intensity of the pulp, keep the foam area stable, and increase the aeration rate. , forming more big bubbles.

Slurry flotation impeller stirring speed is greater than the critical speed required for solid particle suspension; coal slurry flotation machine can operate normally. After the impeller stirring speed is determined, it must be verified by tests. In addition to the above three requirements, the structural parameters of the impeller have a significant influence on the rotational speed. A reasonable impeller and stator structure is designed. The rotational speed of the impeller is greater than the required rotational speed of the dispersed gas.

The competition for resources has become hot at this stage, and high-utilization technology research and development is crucial to the development of slime flotation machines. As an important part of the beneficiation process, ball honeysuckle dryer traffic and pulp density range is ±5%. That is, within 10% of the range, less than 10% of the change in the speed range. The company has a powerful technical team for technical research on slime flotation machines and we are happy with the exploration of science and technology. Science and technology are the development forces that really benefit us.

Impeller stirring speed can not be too high, so as to avoid the destruction of the role of separation zone and foam zone. The impeller speed can be greatly reduced, so as to achieve the purpose of reducing power consumption and spare parts consumption. More importantly, it can improve the technical indicators of the beneficiation process.

Completely abandon the parallel tanks and use advanced tank technology to increase the flotation speed. The size of the selected trough adopts an adjustable device, which can provide a wider operating platform for the workers of the multi-selection technology and reduce the occurrence of slurry retention. According to the process requirements of the flotation device, the determined speed range is less than or equal to 8%. According to the flotation process, the foam appearance, toughness and brittleness are observed. By adjusting the amount of foaming agent, ore slurry level and strict operation, the quality of the foam and the amount of scraping can be controlled.

In an appropriate range, the speed of the impeller of the coal flotation machine is increased, the depth of the groove is reduced, and the gap between the impeller and the cover is reduced in order to increase the amount of aeration as much as possible, which also promotes the flotation speed to some extent. Coal slime flotation machine uses a particle size suitable for the slime of the coal flotation machine as the load body, so that the fine gold adheres to the surface of the load body and becomes a gold concentrate. Coal slime flotation machine uses oil to agglomerate fine mineral particles for flotation oil flotation and emulsification flotation. Separation flotation, which uses high temperature chemical reactions to convert metal minerals from ore to metal before flotation, is not often used with gold ore. With regard to the use of foam flotation to recover gold sludge, China will be used in the industrial field.

The strong turbulent movement of the pulp in the coal flotation machine is the main factor that causes the mineral particles to fall off from the bubbles. Therefore, reducing the turbulence intensity of the slurry movement is the fundamental measure to ensure the coarse-grained flotation. According to a specific process, various possible technical solutions are analyzed and an excellent solution for frequency conversion technology is determined. Red Star Mining Co., Ltd. usually adopts the following measures: appropriately reduce the depth of the tank (using a shallow groove type), shorten the floating distance of mineralized bubbles to avoid the exfoliation of the mineral particles, and add a grid screen above the impeller area to weaken the turbulent intensity of the slurry. The foam area is stable, increasing the aeration rate and forming more large bubbles, which is conducive to the formation of bubbling groups consisting of bubbles and ore particles. The coal slurry flotation machine will move the coarse particles “up and down” to float, and the bubbles must be quickly and smoothly.
