Steel slag is a kind of waste slag produced in the process of steelmaking. If it is not treated in time, a large number of steel slag will occupy land and pollute the environment. With the rapid development of iron and steel industry, the production of steel slag in China is increasing rapidly. The treatment and resource utilization of waste slag in iron and steel enterprises have attracted more and more attention. Relevant studies show that steel slag can be used as road building materials and building materials for comprehensive utilization of secondary resources. Can the steel slag beat the concrete? How much is a steel slag crushing production line? This article provides you with detailed answers.
1. Can steel slag beat concrete?
01. Steel slag contains more active minerals such as calcium silicate and ferroaluminate, which can produce cement and concrete admixtures. The steel slag cement produced has the excellent characteristics of wear resistance, high flexural strength, corrosion resistance, frost resistance and so on.
02. Steel slag crushed stone can replace machine-made crushed stone and fine aggregate as concrete aggregate. Steel slag macadam has the characteristics of high strength, rough surface, stability, wear resistance and low temperature cracking resistance. It can prepare excellent road concrete and marine concrete according to the use demand.
Therefore, under the background of green development, the application of steel slag as admixture or aggregate in concrete can not only reduce the occupation of land and environmental pollution, but also reduce the cost of concrete allocation, which is in line with the policy guidance of solid waste reduction, recycling and harmlessness.
2. What equipment does the steel slag crushing production line need to be equipped with?
01. Jaw crusher - coarse crushing.
Jaw crusher can be used to roughen the original steel slag, with large crushing ratio. It can crush large steel slag below 1500mm to below 400mm. There are many models available, with a capacity of 1-2200t / h.
02. Cone crusher - medium crushing.
The cone crusher has strong crushing force and can easily crush some thorny steel slag with high hardness. The feed particle size is 65-300mm, the discharge range is 5-60mm and the production capacity is 12-2181t / h. After being treated by cone crusher, the steel slag can be changed into 1-2 and 1-3 crushed stones, which can be used as coarse aggregate for preparing concrete.
03. Impact crusher - fine crushing and shaping.
The impact crusher, also known as the impact sand making machine, is mainly used for fine crushing and sand making of small steel slag with a feed particle size of 30-60mm. It is mixed with "stone beating stone" and "stone beating iron". It also has the function of shaping, with a processing capacity of 12-650t / h. It can process the steel slag into standard machine-made sand with a particle size of less than 4.75mm.
In addition to the above equipment, a complete steel slag crushing production line will also use auxiliary crushing equipment such as vibrating feeder, vibrating screen and belt conveyor. For detailed steel slag production line configuration and actual production, you can consult us.
3. How much is a steel slag crushing production line?
A steel slag crushing production line includes many types of equipment. At the same time, due to different output requirements, there are certain differences in the specific selection of equipment models. Different manufacturers, equipment quality, consumption region and other factors will also affect the price of configuring a steel slag crushing production line. Understand the specific steel slag crushing production process and equipment configuration price of the production line.
