Five advantages and cleaning requirements of magnetic dumper
Dump-type iron remover, excellent quality, product protection, have the following characteristics:
1. Large processing capacity: As the company adopts a package-type open magnetic system, the materials are not entangled, and there is no clogging, so the processing capacity is large. The processing capacity of a single primary machine can reach over 50 tons, and it can also be used in parallel with multiple machines. Using them in parallel can double the output.
2. Concentration without water: Due to the company's dry-type dumper, there is no need for water. Compared with water selection, there is no sludge sewage generated, and water resources can be saved. Taking the GXC-8180 primary machine as an example, it can save 600,000 tons of water each year.
3, to adapt to a wide range of industries: The company's dry dumper, divided into four categories, there are more than 20 varieties and specifications. It can meet the needs of various industries such as iron ore, river sand, tailings, steel slag, steel ash, sulfuric acid slag, abrasives, refractories, board, rubber, grain, etc. Some of the equipment can also be used in one machine.
4. High production efficiency: Dry separation is not used for water, so it can be continuously produced without water source limitation. It can increase 100-150 working days per year for water-free areas, seasonal water shortage areas and high-cold areas, effectively increasing the utilization rate of equipment. .
5, good sorting effect: As the machine adopts dynamic magnetic system design, the mineral material slides on the surface of the drum, displacement and roll, roller does not stain material, is conducive to material sorting, primary grade can be increased 1-4 times, once fine The grade can reach more than 60%.
In practical use, the longer the working time of the dumper, the more impurities (ie, the mixture of ferromagnetic substances and mud) absorbed by the magnetic source or iron-absorbing medium, the thicker the surface area mud. The coverage thickness Δh is also proportional to the mud viscosity, concentration, and particle size of the impurities. When the attraction of the magnetic field to the set impurity is Fx'<Fx (Fx - the attractive force required for the original set impurity) and the original set impurity cannot be absorbed, only the magnetic source or the iron-absorbing medium is cleaned in time. The original iron removal effect can be restored to achieve a good iron removal state.
Dump-type iron remover cleaning needs to meet the following requirements:
1. Energy saving and environmental protection. In the cleaning process, the cleaning time is short, the consumption of cleaning water is small, and the environmental pollution is small.
2. The surface of magnetic source or magnetic medium is smooth and clean, and there is no sludge on the surface after cleaning.
3. High degree of automation. It is the trend of the development of the separator to automatically determine the cleaning cycle, automatic cleaning, and automatic treatment of sewage.
4. The row of iron must be thorough. In the design of the iron remover's iron discharging channel, the cleaned sewage must be completely discharged from the machine, and the impurities in the sewage can not be precipitated in the channel, which affects the iron removing effect.
5. The structure is simple. For installation and use, easy cleaning, equipment structure should be easy to install and remove and internal inspection and cleaning.
