China Steel Slag Powder Ultra Fine Grinidng Plant Steam Jet Mill

Steel Slag Powder Ultra Fine Grinidng Plant Steam Jet Mill

Features and Advantages

Available particle size D50:0.5-10μm Nano particle size is available. Steam of working pressure 8-40 bar and temperature 230ºC-360ºC, both drying effect Higher speed of steam results in higher kinetic energy, strong grinding force, high-speed jet nozzle exit speed can reach 1020m / s, can produce finer powder Stronger grinding ability and energy, easy to achieve finer powder. Compared with conventional jet mill, higher energy efficiency, lower operating cost. The grinding process is completed by the collision of the materials themselves., Fully self-grinding, So The device is durable and the purity of products is high in contrast. High speed and low viscosity, can achieve higher grinding efficiency and classification accuracy, reduce over-grinding, and obtain narrower particle size distribution. Good particle shape and high activity. The classifying wheel separates the material automatically with airflow, no coarse particles. Key parts like inner liner, classifying wheel and nozzle are made of ceramic such as aluminum oxide, zirconium oxide or silicon carbide, ensuring non-contact with metal throughout the grinding for high purity of the final product. Single or multi-classifying wheel are installed horizontally. Speed of wheel is controlled by converter, particle size can be adjusted freely. Grinding is in closed system, low dust and noise, clean and environmentally friendly production process. PLC control system, easy operation. Can be used for ultra-fine processing of high viscosity products. The motor can be connected with a belt to increase the speed and break through the problem of high-speed motors without the well-known motor brand. Can be used in series with multi-stage classifiers to produce products with multiple sizes at one time. Weighing control system, high precision, optional, high product stability. Optional explosion-proof design, can also be upgraded to nitrogen circulation system to meet the ultra-fine grinding processing requirements of flammable and explosive oxide materials.

Working Principle
Steam Jet Mill(Steam kinetic energy mill) Upgraded by conventional jet mill.
Adopts unique high-temperature mechanical sealing technology, cooling technology, high-temperature steam as grinding kinetic energy medium, specially designed Laval nozzle drive high-speed collision and grinding of materials.
The grinded material enters the forced vortex classification, the qualified materials enter the heat preservation collection
system,
And the coarse materials fall into the grinding zone to continue the grinding, the whole process is completed under the dry
process.
Application of Steel Slag
The main ways of using steel slag in several world-famous steel producing countries are iron selection, cement raw materials, road construction materials, municipal engineering materials, fertilizers, soil conditioners, part of the steel slag returning to the blast furnace, sintering as flux, etc., comprehensive utilization of steel slag in various countries Development is uneven.
Most of the Japanese steel slag is crushed and recycled by magnetic separation, and the remaining tailings are almost all used in cement, road engineering, concrete aggregates and civil construction materials. At the same time, Japanese steel slag has developed some new technologies in improving the marine environment-using steel slag to repair the marine environment.
German steel slag has a high utilization rate and can replace mineral materials in civil engineering, road engineering, water conservancy engineering and railway engineering technology, and can also be used as agricultural fertilizer and mixed into sintering and blast furnaces for reuse.
The steel slag in the United States has reached a balance of discharge. 37% is used for roadbed projects, 22% is used for backfilling projects, 22% is used for asphalt concrete aggregates, and the remaining steel slag is used for internal recycling of iron and steel enterprises, production of cement, and fertilizer for soil improvement. Britain has developed a dry granulation process for steel slag treatment.
Steel slag is mainly used in asphalt concrete, mass concrete, asphalt road frame material, and road construction materials. Dry granules can be used as cement extenders or fillers.
A small amount of Canadian steel slag is allocated to sintering and blast furnace reuse and road construction, most of which are used for on-site accumulation or transported to other places for backfilling;
Turkey and other countries have also begun to study steel slag as cement admixtures, but they have not yet seen Reports of large-scale applications;
South Africa's soil is acidic, and part of its steel slag is used as a soil amendment, and the rest is buried and stored;
Sweden rebuilds the composition of the steel slag by adding carbon, silicon and aluminum materials to the molten steel slag and then recycles it The slag and steel tailings in the slag are used in cement production.
