The selection of building materials is also a key Construction Waste Crusher link. According to reports, the current use of cement hollow bricks, there must be a 28-day maintenance period, or easy to damage. Some builders were eager to launch construction projects. The use of such hollow bricks resulted in substandard quality. After being discovered by the engineering supervision department, they had to be reworked. This not only wastes resources but also generates construction waste. Recycling requires governments to support difficult governance, and the source is difficult to block. Words such as "renewable use" and "recycling factories" gradually become popular. During the interview, relevant people all learned about the importance of recycling of construction waste.

Construction waste is mainly waste concrete, waste bricks, etc. After Construction Waste Crusher processing, it can be used as a roadbed or aggregate for concrete production, and it can also be used as raw materials for building materials. Usually also contains wood, scrap metal, waste rubber, plastic waste, packaging materials, etc., after separation can be used as the corresponding industrial raw materials. According to relevant data, a recycling plant can process at least 110 to 275 tons of construction waste per hour, and can process and sell at least 200,000 tons of recycled aggregate each year. It is understood that the city is located in the coastal area, the city's area of ??160 square kilometers, the original sand, stone, soil used for construction is scarce, after many years of mining has become more scarce, so the construction waste recycling is imminent.

However, it must be pointed out that the competitiveness of recycled building waste aggregates compared with natural gravel is weak, mainly because the market acceptance is not high, and whether construction companies will use recycled building materials is still unknown. According to the director of the Municipal Department of Environmental Hygiene and Environment, 400,000 tons of construction waste each year can produce 150 million bricks and 50,000 houses can be built. In terms of this city, market demand is not yet estimated to be so large. It can be seen that, due to comprehensive factors, the renewable use of construction waste is not yet a profitable industry. Relevant sources believe that the recycling of construction waste is subject to the government's guidance, dispatching personnel to visit other places for reference, drawing on advanced experience and treatment methods, and if renewable enterprises are put into operation, they also need preferential policies.

    add to favorites Discourse on the Method of Preventing Liner Wear of Ultrafine Mill Pc  

    Ultrafine Mill is one of the essential parts of mineral processing equipment. Many users of ultrafine mill complain that the liner plate of a ultrafine mill is with short service life and a high production costs. Henan Mining Machinery summed up key factors influencing the liner wear of a ball mil based on years of production experience, which as a reference for the users of ultrafine mill. Hope it can help the users avoid a similar situation in production and prolong the service life of ultrafine mill liner plate. The key factors influencing the liner wear of a ultrafine mill generally include the following several points:

    The Ultrafine Mill of media material. The generally used crushing media material include: various mine materials (manganese, copper, tungsten ore, chrome ore, etc.), various types of stone (limestone, granite, gneiss, basalt, gray rock, etc.) and industry coal used in power. The hardness of the media is the main basis that determines the liner plate wear, the higher hardness of the media, and the shorter service life of the liner; on the contrary, if the media is with a lower hardness, the service life of the liner will be prolonged. The impact of operating conditions. 1) Eliminate defects not timely. 2) Adjusting undeservedly makes the ultrafine mill running at short positions.

    The impact of liner material. The main parameters affecting the anti-wear effect is matching of the two index of hardness and impacting toughness of liner material. If the liner plate has a higher hardness, which means it has a good wear resistance, and the two factors basically is a proportional relationship. The impacting energy depends on the size of the diameter of steel ball and grinding tube. 4, the impact of the ultrafine mill's designing and manufacturing and the installing quality. The performance of the lining plate generally include the following two: one is to protect the cylinder; another is that the liner plate rotates at a specific speed to raise the ball to the required height to achieve the desired effect. The quality of the liner plate is also direct factor affecting the normal operation of the mill. Those above are the main factors affecting ultrafine mill liners; we recommend that you should firstly consult the expert before you buy a ultrafine mill. And you'd better go to the manufacturers with strength production and reputable brand purchase.

    The mechanism sand production line has many advantages, such as crushing hard minerals and crushing minerals selectively. In the process of production, the fineness of finished sand can be adjusted according to the different requirements. So the application range of sand making machine is very wide, but the advantages of the equipment are completely established in the normal work. On the basis of this, there is a great relationship between the normal work of the equipment and the installation of the equipment. Here is an introduction to what matters to be noticed in the installation of the mechanism sand production line.

    Whether the working environment of the sand making machine is indoor or outdoor, the foundation must be made of concrete to ensure that the equipment has a solid foundation. The requirement for the foundation of the concrete is several times as many times as that of the whole mechanism sand production line, which will be explained by the manufacturer when it is purchased.

    The mechanism of sand production line must be balanced to make the main shaft perpendicular to the horizontal line to ensure that the equipment does not meet the requirements of the finished product in the process of production.

    Then it is due to the long time transportation of sand making to the site of the production project. It is unavoidable that there are collisions in the process of transportation. So the equipment must be checked thoroughly before the installation. For example, check whether the lubricating tubing is connected, and add oil before the test is installed; and then, check the inspection. Check whether the connection is reliable, check whether there is any foreign object on the impeller, if it is discharged this morning, and ensure that the rotation direction of the motor is the same as that of the mechanism sand production line. If the motor wiring is not always adjusted, the direction of the motor is consistent with the sign.

    With the fast development of the economy in our country, the control strength of our government for scarce resources has been gradually increasing, and the Ultrafine Mill fluorite is one of the national strategic resources. Because our government steps up efforts in the integration and protection of the fluorite resources, the fluorite resources will be integrated by some large-sized company with huge scope and technological advantages in the future. As the most important fluorine source, the reserve and production ratio has been continuously decreasing. In recent years, a lot of resources have been wasted, and the Ultrafine Mill application of the fluorite is very wide, for this reason, the application value of fluorite is higher and higher. The previous scattered and mussy mining resources exploitation has been gradually developing toward integration of large-sized mineral resources companies. Large-sized machines and professional types of configuration are the focus of the integration, and they will improve the exploitation efficiency of the mineral resources and improve the safety performance in the mineral exploitation process.At present, the devices of the fluorite production companies in our country is relatively small in production capacity, and it has not any scale advantages, and in addition, the over-exploitation to the fluorite in our country causes serious waste of the resources so that the resources utilization rate is very low. For this reason, the fluorite industry in our country has inner requirement for resources integration. Compared with common powder collector, the bypass powder collector has little pressure loss and high collecting efficiency, so that it is beneficial to collect the super-fine particles that are difficult for the common powder collector to collect and the machine is environmentally friendly. The fluorite ultrafine mill adopts the same resistance devices in the machine in order to avoid the different contribution of the two powder collector, so that it will improve the powder collecting efficiency, reduce internal cycle and improve the production capacity of the ultrafine mill. We have many years of production experience in grinding mill, and our country have wide customers resources, and the equipment researched and developed by our country enjoy wide popularity among the customers after they are put into use.
