About grinding equipment
Limestone powder is used for desulfurization in power plants. Which equipment is suitable for desulfurization?
The continuous development of the electric power industry has brought about a series of environmental problems, especially the atmospheric pollution of coal-fired power plants. The sulfur dioxide and scoot from coal-fired power plants are the main sources of air pollution in China. The treatment of the discharged wastes is an effective way to reduce environmental pollution. The post combustion desulfurization technology refers to the technology of removing sulfur dioxide from the flue gas discharged from the combustion device. According to China's national conditions, flue gas desulfurization should be the main way to control sulfur dioxide emissions in thermal power plants, and should be vigorously promoted. Limestone desulfurization is the main raw material for desulfurization in power plants. Limestone can be made into desulfurizer after being processed into powder by grinding machine. Vanguard Machinery produces a series of grinders based on the same equipment products at home and abroad are updated and improved design, especially suitable for limestone powder processing and production, its high efficiency, low power consumption, small footprint, small one-time investment.
How can we turn stones into powder? What equipment are suitable for making stone into powder?
At present, there are more than 300 kinds of stone materials, such as calcite, cobblestone, limestone, bentonite, coal gangue, granite and so on. These materials are already existing in the nature in large granular form. These large stone materials can be processed into powder and used in various industries. But what kind of equipment is used to powder the stones? The original ore grinding equipment was Raymond mill. After continuous improvement and technological research and development, high-pressure medium-speed mill, hyper pressure V type grinder and European type grinder were put on the market. There were also three-ring medium-speed grinder, high-pressure micro-powder grinder and ultra-fine powder mill for ultra-fine powder processing, as well as coarse powder processing. The straight centrifugal grinder can process the ore to 30-2500 mesh and meet the different needs of users.
What is the process flow of petroleum coke fine powder production line?
Petroleum coke is a kind of coke produced by distillation of crude oil and thermal cracking of heavy oil, and delayed coking of residue oil. Most of the petroleum coke produced in China belongs to low sulfur coke, mainly used for smelting aluminum and making graphite. It can also be used as fuel, but it needs petroleum coke ultra-fine grinding equipment for ultra-fine grinding to make coke powder before it can be burned. At present, some glass factories and coal water slurry factories mainly use coke powder as fuel. For various uses of petroleum coke, Vanguard Machinery has introduced petroleum coke production line for petroleum coke processing, which mainly consists of jaw crusher, petroleum coke grinding equipment, classifier, cyclone collector, pulse bag filter and corresponding motor, electronic control, feeder, collector and unloading device.
Specific process: the crushing of petroleum coke powder in the preliminary stage-jaw crusher (if the feed size is less than 3 cm) processing to the fineness of less than 3-5 cm to meet the needs of ultra-fine grinding. The feeding equipment is composed of a fully sealed vibrating feeder. The feeding is connected with the elevator or belt conveyor and totally closed to the hopper. Then it is ground, which consisting of Raymond mill or ultra-fine grinding. Then the quasi-qualified powder which has been crushed will be graded. Meanwhile, the qualified powder will be collected by cyclone collector, and the unqualified powder will be returned to the grinding equipment for further grinding until all the required particle size is reached. The required powdered particles will be collected for dust cleaner. The petroleum coke powder is easy to run off the dust, and bag dust catcher can block 1 micron of ultra-fine powder to ensure environmental cleanliness. The unloading material adopts large hopper with high sealing bin, and finally discharges other impurities. The whole production line can run for a long term. The finished product of petroleum coke powder has uniform fineness and high quality. The whole set of petroleum coke production line is operated under negative pressure with the large air flow rate, and its operating temperature is about 55 degrees. Whole production site is free of dust pollution, and the system discharge meets the national environmental protection requirements.
