Steel slag is the waste slag discharged during steelmaking, which is a kind of industrial solid waste. The treatment method of steel slag is random placement and discarding, which not only occupies the land area, but also easy to cause varying degrees of environmental pollution. Steel slag is mainly composed of oxides such as calcium, iron, silicon, magnesium and phosphorus. Except that silicon is useless and phosphorus is harmful, other substances can be used. Therefore, the reuse of steel slag is a profitable industry.
With the progress and development of science and technology, the utilization technology of steel slag has also changed from backward to advanced. The treated steel slag can extract trace elements and add them to fertilizer, can be used as land making materials for pit filling and sea reclamation, raw cement, brick making, tile building materials, etc. Most steel slag reuse technologies have crushing steps. This paper focuses on the steel slag crushing equipment for a detailed description.
1.Steel slag crushing equipment.
Steel slag crushing equipment is mainly used for crushing large steel slag to provide stones needed for various construction fields. It is commonly used for jaw crusher, impact crusher, cone crusher, hammer crusher and other equipment, but also according to the size of raw materials, hardness and production environment.
01. Jaw crusher - coarse crushing.
Jaw crusher is the key to coarse crushing of large steel slag and the preferred crusher in most enterprises. The equipment has the advantages of large crushing ratio and uniform finished product particles. It can crush materials with compressive strength not exceeding 320 MPa. The structural design of the equipment is reasonable, simple and convenient. There is no cumbersome working principle and operation process. The operators are also handy in learning, companies can spend less time on training.
The jaw crusher has multiple models, with an output of 5-1000 tons per hour. Customers can buy it according to the actual scale of their own enterprise. The sales price is not as high as other equipment, it's an economical steel slag crushing equipment.
02. Cone crusher - medium crushing.
Cone crusher is the introduction of foreign advanced technology and domestic mine development combined with the product, the main is some of the pursuit of high efficiency, adhere to the concept of environmental protection of some emerging enterprises. The machine uses grease labyrinth seal design, basically eliminate the occurrence of dust and noise, to prevent the water supply and drainage system is easy to block the defects and water and oil mixed defects.
There are a variety of possible combinations of crushing chamber, instead of the traditional crusher single crushing chamber design, not only can obtain better crushing effect but also meet the needs of special users, it can be said to kill two birds with one stone.
03. Impact crusher - medium crushing.
The impact crusher is a common steel slag fine crushing equipment, which can adjust the distance between the impact plate and the lining plate to realize the random adjustment of the finished particles. The finished particles are uniform and intact without cracks. The machine adopts the design mode of seamless connection, which reduces the number of equipment failures, and is very convenient for maintenance.
The equipment is small in size and light in weight, which can adjust the position of the equipment flexibly and conveniently according to the needs of enterprises. When the equipment is running, steel slag is broken along the joint surface, so it consumes less power and energy. The crushing of impact crusher is not affected by the water content of steel slag. When the water content of steel slag is too high, heating device can be added to effectively prevent the occurrence of accidents caused by the blocking of crushing cavity caused by the bonding of steel slag.
04. Hammer crusher - coarse / medium / fine.
The hammer crusher relies on the impact force of the hammer head to complete the crushing of steel slag. The greater feature is that it has a strong crushing capacity, which can turn the traditional three-stage crushing into one-stage crushing, and the coarse, medium and fine crushing can be in place in one step.The equipment in addition to the overall use of high-quality steel casting, wearing parts are also made of special wear-resistant material high manganese steel, compared with ordinary steel, impact resistance and wear resistance is higher, not only reduce the replacement frequency of wearing parts, but also prolong the service life of the whole equipment, improve the production efficiency and output.
2.How much is a steel slag crushing equipment?
The price of a steel slag crushing equipment usually ranges from about 200000 to 1 million. In addition to the model reason, it is also closely related to the design, material selection and technology of the equipment. In addition, there are many crushing equipment manufacturers in the market, including self-produced and self-sold, middlemen, second-hand, etc,and the price is slightly different.
For the specific price of steel slag crushing equipment, you can consult the quotation. SMMVIK Machinery has more than 25 years of experience in mining machinery production, has perfect quality management, can conduct on-site investigation, and the equipment will be in the hands of customers as soon as it leaves the factory, and there is no middleman to earn the price difference, welcome to visit the factory.
