The strength of this kind of concrete brick made from construction waste exceeds the national standard by nearly 20%. The construction waste can also be used to make pavement brick and wall brick, and the price of garbage brick in most areas is cheaper than that of common clay brick. The production will turn the construction waste into recycled building materials after treatment, which can be used in building design and road laying. This measure will greatly reduce the consumption of natural materials on the environment and resources, and has good environmental protection significance. As well as on-site installation and after-sales commitment, customer requirements in the process of installation and use can be efficiently met. The mobile crushing station for the treatment of construction waste usually uses the counterattack mobile crushing station + mobile screening station, which depends on the situation of users. In order to better deal with the large amount of construction waste produced in Liming, liming machinery has studied the comprehensive utilization treatment equipment of construction waste through continuous research and development. The relatively new mobile construction waste crushing station has been successfully developed and applied for the national construction patent, which fills the gap in the construction waste resource treatment market and is used in many places. The customer satisfaction is very high.   。 Zhengzhou Liming Machinery Equipment Co., Ltd. specializes in developing series of rock and construction waste crushing equipment for mobile construction waste crushing station, which greatly expands the concept field of coarse crushing and fine crushing operation. 2. The vertical impact crusher can work under closed or open circuit conditions. The reduction of construction waste refers to the reduction of the production and emission of construction waste from the source. It is the comprehensive management of the quantity, volume, type and harmful substances of construction waste, that is to carry out clean production. The production process of the mobile artificial aggregate processing system is basically the same as that of the traditional artificial sand and gravel processing system, but the mobile artificial sand and gravel processing system reduces some intermediate links, shortens the transportation distance of materials, improves the degree of automation, optimizes the equipment configuration and layout, and is superior to the traditional artificial sand and gravel processing system from the use effect. (5) The price of sand and stone is affected by origin, transportation distance and supply-demand relationship. Adopting the new manufacturing technology and structural design, the finished product is cubic, no tension and crack, and the grain shape is quite good. It can crush all kinds of coarse, medium and fine materials (granite, limestone, concrete, etc.) with the feed size not exceeding 500mm and the compressive strength not exceeding 350Mpa It is widely used in highway liming, water conservancy engineering and construction macadam processing. 4) After the roller crusher has been running for a long time, due to the wear of the roller surface, the product particle size will be too fine. At this time, it is necessary to adjust the ore discharge port or overhaul the equipment. The development of sand making machine is closely related to human technological progress, modern science and technology and the overall industrial level, and plays an important role in the dawn of national economy. 2. The special hammer head manufacturing technology of coal gangue crusher makes the hardness of hammer strengthen, and the service life of hammer is increased by 2 to 3 times. 12、 In this paper. Technical documents and drawings shall be strictly followed. The installation on paper requires installation. If there is any problem, it should be solved through consultation with all parties, and record and answer procedures. The test results of the bearing of the vibrating screen show that the radial natural frequency of the bearing elastic system is reduced due to the excessive radial clearance, which is easy to produce resonance and produce large low frequency vibration. The machine is supplied in the form of complete assembly. However, it is necessary to carefully check whether the machine is damaged and whether the sliding part and lubricating part are rusted during long-term storage during transportation. After the machine is installed and leveled, the transmission part shall be installed according to the drawing. The transmission belt shall be adjusted to be tight and tight When the position, dawn spring must be adjusted to the appropriate position. Xu Xiangchun said that nonferrous metals are "sweet cakes", but they are not so "good to eat". Zhengzhou Liming Mining Machinery Co., Ltd. (formerly state-owned Henan mining machinery factory) is a new technology enterprise which is engaged in the development and production of crushing and screening equipment, sand preparation and washing equipment, complete set of mineral processing equipment and mobile crushing and screening system of urban construction waste. In the traditional dry sand production line and wet sand production line, coarse and fine powder separator, spiral sand washer or bucket wheel sand washer are used to recover and clean sand. Especially in a large number of wet sand production lines, fine sand less than 0.2mm is lost through the sand washer, and even enters the sedimentation tank together with debris and sludge, causing sedimentation in the sedimentation tank, which not only pollutes the environment, Moreover, it causes a lot of waste of fine sand, which can not be recycled, and causes great losses to the customers of the stone factory. The crawler mobile crusher has compact structure and strong mobility, can directly enter the urban construction waste treatment site, and has low transportation cost. Shandong granite production line panoramic 750 × 1060 jaw crusher. PCX high-efficiency fine crusher has been widely used in the crushing of non-ferrous metals such as gold, silver, copper and iron in mines, as well as the material crushing field of non-metallic, refractory, potassium feldspar and other ceramic production lines in traditional quarries, and has achieved good economic and social benefits.
