Steel slag is an inevitable derivative of steelmaking process, mainly composed of calcium, iron, silicon, magnesium and a small amount of oxides of aluminum, manganese and phosphorus. In recent years, SBM has taken various measures to make steel slag recycling equipment and achieved secondary recovery of some steel slag. With the large-scale production scale of SBM Iron and Steel, the annual production of steel slag has reached more than 1.3 million tons, but the comprehensive recovery rate of iron-containing raw materials is low, and it is necessary to follow up with supporting facilities. To this end, SBM started construction of a steel slag Vertical Roller Mill magnetic separation processing line on the basis of the original 30-ton furnace plant and supporting facilities of the steelmaking plant at the end of August last year. The project adopts advanced, reliable and low-cost process technology. The production equipment is divided into six parts: screening, crushing, magnetic separation and vertical roller mill. Different types of magnetic separation equipment can be set according to the properties of steel slag with different particle sizes. The magnetic separation equipment has strong adaptability and high recovery rate of steel slag, and the annual processing capacity of steel slag is more than 1.4 million tons. The recovered slag powder and medium sieve block are mainly used for ironmaking sintering and steelmaking converter production, further reducing the production cost of pre-iron and steel post-process. At present, the comprehensive utilization of steel slag at home and abroad has undergone major changes compared with the past. The guiding ideology of steel slag management has changed from a simple environmental perspective to comprehensive management and resource utilization. Steel slag can be used as iron-making flux, directly added to blast furnace or sinter, and recycled inside the steel plant. It can also be used as a cushion and structural layer of road subgrade. It is especially suitable as an aggregate paving layer for asphalt mixture. Road construction with steel slag has the advantages of high strength, good wear resistance and slip resistance, and low maintenance cost. Shanghai SBM research and development of environmentally-friendly large-scale steel slag vertical roller mill, specializing in steel slag processing, so that it can be used for sustainable use, tailor-made for the enterprise to create a good strategy.

In the building materials market, Marble Grinding Machine is a widely used material that can be used in the production of building materials after being processed by a mill. So, which kind of mill is suitable for the processing of marble powder? Marble powder processing can choose two kinds of grinding equipment, one is Raymond mill equipment, and the other is high pressure mill equipment. Both of these milling equipments can be used for the processing of marble powder. The Raymond mill has a fineness of less than 300 mesh and a yield of between 8 and 10 tons. The high-pressure mill is more powerful than the Raymond mill, and the fineness of the processed marble powder can reach 500 mesh or even higher. The output of high-pressure mills is also relatively large, and the output of large-scale equipment can reach 15-20 tons.

For the investment of construction waste crusher, we hope to choose equipment with good quality and excellent performance, but the choice of this equipment also needs to consider many reference factors, such as price, market evaluation, manufacturer reputation, etc., different customers. When choosing these different devices, the reference standards are different. Some customers will choose according to market evaluation. Is this method reliable? Market evaluation is also the feedback of customers. It is relatively true. For example, when we buy electrical appliances or clothes, we choose according to the big brands with good reviews on the market, so we are building When a large-scale mining equipment such as a garbage crusher is selected, some people use a similar method, but this method is not feasible. Let us introduce the reason for this phenomenon. Because the construction waste crusher is a production equipment, when it is working, depending on the production requirements, different models can be selected to complete the material processing. In the process of production, if the selected model is unreasonable, then It will cause the efficiency of production to reach the customer's demand. In addition, because different types of equipment work, the processing capacity is different. If the selected model does not meet the production requirements, the equipment wear will also increase. At work, not only is the efficiency low, but also the phenomenon of frequent failures. Therefore, when selecting a construction waste crusher, market evaluation is important, but more important is whether the equipment is suitable for the needs of its own project. Generally speaking, when purchasing, factors that need reference are not included in the market evaluation. It also includes the demand for capacity, the nature of the material, the size of the manufacturer, etc., and comprehensive consideration can be used to purchase good equipment. The article mainly introduces the question of whether the construction waste crusher is feasible according to market evaluation. The above analysis of this problem is more detailed, and the answer is not feasible, because different equipments have different application scopes, only suitable for themselves. Equipment for production needs can be a good choice.
