Steel slag is a waste residue generated during the steelmaking process and is an industrial solid waste. In the national development plan, it is stated that the comprehensive utilization rate of steel slag should reach over 86%, achieving "zero emissions." Steel slag is mainly composed of oxides such as calcium, iron, silicon, magnesium, and phosphorus. Except for useless silicon and harmful phosphorus, the other substances can be utilized. Therefore, the recycling of steel slag is an industry that adapts to the trend.
With the progress and development of technology, the utilization of steel slag has also advanced from backward to advanced. There are two main pathways for the comprehensive utilization of steel slag as a secondary resource. One is its use as a smelting solvent for internal recycling in the plant, which can replace limestone and recover a large amount of metallic iron and other useful elements. The other pathway involves using steel slag as raw material for manufacturing road materials, construction materials, or agricultural fertilizers.
Commonly used equipment for steel slag crushing includes steel slag-specific jaw crushers, cone crushers, hammer crushers, rod mills, and other equipment, which are determined based on the size, hardness, and production environment of the raw materials.
PEY Hydraulic Protection Jaw Crusher - Coarse Crushing
The hydraulic protection jaw crusher is a special crusher designed for steel slag. It is equipped with overload protection function. When encountering unbreakable materials, the hydraulic cylinder load rises sharply, and the "iron overload" is automatically retreated through the hydraulic system. After the iron overload is completed, it automatically resets. It is especially suitable for continuous crushing of materials with multiple barriers and non-single media. Compared with ordinary jaw crushers, the hydraulic protection jaw crusher is reliable in protection, automatically discharges unbreakable materials, effectively solving the problem of "steel jamming" in steel slag crushing. After iron removal, it automatically resets, realizing continuous production without stopping the machine, greatly improving production efficiency, and achieving energy saving, emission reduction, and comprehensive utilization of waste. Its hourly output ranges from 16 to 280 tons, making it an economical and practical steel slag crushing equipment.
GPY Single Cylinder Hydraulic Cone Crusher - Medium/Fine Crushing
The hydraulic cone crusher is a product of Dahua Heavy Machinery, which combines advanced foreign technology with domestic mining development. It is a highly efficient hydraulic cone crusher with large eccentric distance, high swing frequency, and layered crushing. It has a special adjustment method for the lining plate, ensuring stable cavity shape and higher lining plate utilization. The discharge granularity is uniform. It is mainly focused on emerging enterprises that pursue efficiency and adhere to environmental protection concepts. The cone crusher also has a unique hydraulic safety device. When foreign objects enter the crushing chamber and cannot be crushed, the safety device will automatically adjust the discharge outlet to ensure smooth ejection of the foreign objects. After the foreign objects are discharged, the machine will return to its original state. This device effectively avoids damage to the equipment by foreign objects, reduces the frequency and possibility of equipment maintenance, and extends the service life and efficiency.
Efficient and Energy-Saving Rod Mill - Fine Sand Making
The efficient and energy-saving rod mill is a new type of high-efficiency and energy-saving product based on the traditional rod mill technology in China. It is named after the grinding body loaded in the cylinder, which is a steel rod. This series of rod mills adopts high-end rolling bearing support instead of traditional Babbitt alloy bearing support, resulting in low operating resistance, 10-20% energy savings, and more than 20% increase in production capacity.
In addition to the three mentioned crushing equipment, DaHua Heavy Machinery also produces compound crushers, vertical impact crushers, mobile crushing stations, and other crushing equipment. These products have good quality and competitive prices. You are welcome to contact them for more information or to make a purchase.
