Energy Analysis and Optimization Measures of The Ore Dressing Plant

The Ore dressing plant is a major production unit and an important component of the mining enterprise. It uses a variety of mineral processing methods and processes to obtain a high-grade concentrate from the ore. From an economic point of view, the ore dressing plant is generally built near the mining area to reduce transportation costs. The building is constructed on a slope with a certain slope to transport the material by gravity. Ore dressing is the most important part of the production of minerals and is a key sector in mining companies.

Saving energy and reducing costs have always been an importantissue for the ore dressing plant. Some ore dressing plants have coarsercrushing sizes and lower ball mill processing capacity, which in turn affectsthe system capacity of the entire ore dressing plants. At the same time, thedegree of automation of the system equipment is not high, the power of theentire power grid is not high, and energy conservation and consumptionreduction are even more urgent. Below are a few measures that can effectivelyaddress high energy consumption.

First, through technological transformation, increase the loadrate of equipment and increase production capacity.

If the grinding and crushing, multi-grinding and grinding processare used to increase the capacity of the ore dressing plant, the unit energyconsumption and cost can be reduced. It is also possible to modify the crushingsystem, pre-screen, check the screening screen and modify the load rate of eachcrusher.

Second, the use of advanced equipment to reduce energy consumption

The combination of the application of new equipment and the upgradingof existing equipment has better energy-saving effects. Such as highconcentration tailings conveying technology and new equipment 2DG250/3.0 oilisolation mud pump, not only can meet the requirements of the processing plantto increase the processing capacity, but also can save power by measuring theoperating power.

Third, energy-saving potential, implementation of frequencycontrol technology

The frequency converter has many advantages such as completecontrol function, protection function, less maintenance, stable performance,power saving, etc., and has wide application in the ore dressing plant.Adopting frequency converter speed regulation, it has the characteristics ofhigh efficiency and low power consumption.

Fourth, improve the power factor of the power grid

The use of reactive power compensation to improve the power factorcan save energy and reduce operating costs. While improving power quality, italso brings considerable economic benefits to enterprises. In the production,through reasonable selection of electric motors, improve the quality ofmaintenance of one-step motors, rationally select the variable capacity andimprove the operation mode of the variant. For the distribution with low loadrate, the method of “removing, changing, stopping” is generally adopted toincrease the load rate to the optimal value, thereby improving the naturalpower factor of the power grid.

Fifth, other energy saving measures

The in-vivo recycling of ore dressing water is another importantway for mines and mineral processing to promote energy conservation andconsumption reduction. It is necessary to actively develop the use ofcirculating water and increase the monitoring and assessment of the use ofwater recycling.
