The world's first patented cone crusher published in 1878, was made in 1898 products. The United States in the late 1800s began to use a cone crusher. Spring cone crusher is Milwaukee Simmons brothers designed, it was Mingximengsi cone crusher. So far, about a hundred years of history of the aircraft, while gradually improved, becoming more perfect structure, but the basic structure has not materially changed. Imitation of the Soviet Union 2100 and 1650 spring cone crusher in 1954 on the basis of their own design and production of the 1200 spring cone crusher. In 1958 he designed and manufactured a large 2200 spring cone crusher. After years of repeated research and practice, have to overcome the deficiencies of the old series of spring pressure, low intensity and some shortcomings on the part structure, is now mass production of spring cone crusher has 600,900,1200,1750,2200 five specifications 14 kinds of cavities. The machine has a hydraulic system to adjust the crusher setting day of size, the hydraulic system can effectively ensure the safe operation of the equipment. When a foreign body in the crushing chamber, the hydraulic system allows automatic under dynamic cone back, when is expelled, the system of the lower back of the movable cone crushing chamber automatically reset means movable cone and fixed cone geometric form of the question, space. Crushing chamber shape greatly influence the overall performance. Crusher cavity is broken main technical indicators. Labyrinth seals, replace the water seal used in the past, so that dust can not enter the man-machine body of impurities, thus ensuring clean Run edible vegetable oil, extending the slide bearing, thrust ball bearing service life, making the machine reliable operation .. Cone crusher new structure to replace the broken wall very quickly. Aircraft selected high pressure displacement sensor, adjust the position of discharge port is performed in the operating room. As long as a button, it displays the operating table, you can see the need to adjust the size of the port of discharge, very easy and accurate. The crusher is suitable for crushing metal mine concentrator third or fourth paragraph break; for building materials or non-metal mining and civil engineering. Especially the lack of civil engineering required to supply natural sand areas. Compression test jaw crusher how MPa at a standard jaw crusher widely used in metallurgy, chemicals, building materials, shop, transportation and other industrial sectors, restraint overload damage jaw crusher, jaw crusher must Detailed often maintenance and periodic maintenance, the layout is simple, solid, something reliable, easy maintenance and repair costs as well as production and configuration less than the power of jaw crusher, as well as the scope of the social demand and production of cement, building materials and other materials increasing, other crusher in the use of operating processes. For breaking strength at 147 ~ 245MPa various ores and rocks of coarse, medium and piecemeal. Thereby jaw crusher play in people a huge role in the economy, as well as the scope of the social demand and production of cement, building materials and other materials growing. Jaw crusher main frame, eccentric shaft, big belt pulley, flywheel, moving jaw, side guard, elbow board, elbow board seat, gap adjustment screw, reset spring, fixed jaw plate and movable jaw plate and other components, which also play a role as insurance bracket. Jaw crusher making it a significant advantage in gravel production line work process boost productivity, boost the rapid development of sand production line industry. During assembly, Liaoning crusher, if the part has assembly errors in the model, then, in the assembly will be prompted to place and cause of the error, which can promptly correct design errors. The establishment of a jaw crusher frame mechanics model, cone crusher, when the assembly error correction to be analyzed according to various parts of the actual assembly relationships, and then determine where the error is, the last of error correction; if necessary, enter the part environment, to have the wrong parts to be modified or re-modeling.
