With the rapid urbanization process, a large amount of construction waste is generated. The construction waste components are composed of waste bricks, concrete, rock, scrap iron wire, steel bars, electric wires, etc. These materials can be recycled and reused after processing, so the reasonable disposal of these construction wastes has become the focus of increasing attention. China's construction waste crusher started late, and the treatment of construction waste is imminent. Now the demolition of the city and the urbanization of the countryside have produced a large amount of construction solid waste. Due to the dumping and landfilling of these wastes, not only the land but also the temperature is occupied. Under the action of water, the wastewater generated by fermentation and scouring causes serious pollution to groundwater and air. The recycling of construction waste is a systematic project. We must attach great importance to improving the technical treatment level of constr...

In the mining machinery market, there are many kinds of Zenith Crusher . Among them, common crushing equipments include: jaw crusher, impact crusher, cone crusher, hammer crusher, mobile crusher, etc., facing many crushing equipment, customers It is difficult to choose. Today, ZENITH machines are analyzed from the classification and performance advantages of common crushing equipment, which is convenient for users to purchase. 1. Jaw Crusher The smashing is mainly a kind of rough breaking equipment, which is mainly used for crushing various materials with compressive strength not exceeding 320 MPa. It is often used in the crushing stone production line. The performance advantages of the jaw crusher are many, for example: wear resistance The material structure with good performance guarantees the wear resistance of the wearing parts and prolongs the service life; the structure design is reasonable, the discharge port is adjustable, the breaking capacity of the different materials is im...

The small series of SBM cobblestone sanding machine introduces how to solve the vibration problem of small sand making machine. Small sand making machines are being used because they are exposed to harder rocks such as granite, limestone, pebbles, sandstone and shale. Both pressure and wear are greater. Sometimes small sand making machine vibrate strongly. Once the small sand making machine vibrates strongly, the output of the material will be affected, and if it is serious, the entire machine will be damaged. When the small sand making machine vibrates strongly, three main measures should be taken: 1. Ensure that the weights of the two sets of hammers in the small sand making machine are balanced. In general, the quality of the hammer cannot be guaranteed to be the same. There is an error value. This error will not exceed 5 grams. It will not work. If it exceeds 5 grams, it must be noted. At this point, it must be replaced. One of them makes the weights of the two hammers equal. 2. ...

The main component of limestone is calcium carbonate. It has a wide range of sources, diversified uses and low cost. Generally, it must be subjected to deep processing such as crushing, crushing, and grinding in the process of use, and can be applied to various lines. Lime and limestone are used extensively as building materials, the most common being raw materials for the cement production process industry and an important raw material for many industries. Limestone can be directly processed into stone and fired into quicklime. To select mining equipment for limestone production and processing, first of all, what is the production, such as the use of two or three jaw crushers for roadbed. What crusher should I use for the limestone production line? Of course, there are a variety of configurations, and it is best to consider the economic strength according to the purpose. In the process of limestone production and processing, crushing machinery is the most important production equipmen...

In the process of social development, the product of construction waste is compliant, and it is increasing, affecting people's normal life, and also exacerbating environmental pollution. The emergence of construction waste crusher solves this problem, so it deals with construction waste. What is the efficiency of this? We know that there are many types of construction waste, many of which are difficult to degrade under natural conditions, such as cement sandstone concrete, so it must be removed by external force, which cannot be solved manually. Fortunately, there is a crusher specifically for construction waste, otherwise it is difficult to imagine the scene of garbage accumulation. Construction waste is actually a misplaced resource. It can be used to make bricks after being processed by a crusher. It can be paved and even used as a raw material for concrete. It is necessary to pay attention to the transformation of construction waste. Turn waste into treasure, and also save re...

With the rapid development of buildings, railways, highways, water conservancy, bridges and buildings, as well as the continuous development of engineering, mining, coal, and construction industries, the constant demand for highways and housing construction, sand making machine is also facing the momentum. Reform and innovation, the demand is increasing day by day, coupled with the gradual increase of its broken technology and output, deeply trusted by customers! The dry sand production line of the artificial sand production line: the so-called "dry method" means that the sand in the artificial sand is not removed by water during the artificial sand making, but the mud inside the sand is used by using the classifier. The powder is removed to reduce the mud powder content in the artificial sand, thereby obtaining better sand and ensuring the quality and grade of the sand. The Veken Heavy Dry Sand Production Line has been favored recently and has been sold to many countries a...

As we all know, the sand making machine is composed of many parts as a large-scale mechanical sand device. The parts of the sand making machine will also need to be repaired due to the time of use. The repair of the sand making machine parts is not only chrome plating but also iron plating. The essence of the iron plating process is the precipitation of iron from a hot electrolyte at high current densities. In this way, the plating speed can be increased by about 9 times compared with that of chrome plating, and the thickness of the plating layer can be up to 3-5 mm. The iron coated layer has a hardness of Hb = 180-200 and can be subsequently carburized; the hardness after carburizing can be increased to Hb = 500-600. When repairing parts with severe wear, the surface can be iron-plated and then chrome-plated. At this time, the hardness of the coated layer can reach Hb=700-800. The process of iron plating is as follows: (1) Machining the parts (turning , grinding) to eliminate scratc...
