The Technological Demand and Indication of Impact Crusher
8 November, 2012 at 5:24 am in Computer
The mechanical processing surface should meet IT13 level, while the non-machined surface of the metal structure should meet the IT16 level. Second, the tolerance of the roundness and cylindricity on the surface of the form and position tolerance not noted should be half of the tolerance value of the diameter size. Third, all the welding should comply with the provisions of Q/JC05.
The technical requirement is the basis for the design and manufacturing of the impact crusher, which is also the necessary technical performance indicator in order to meet the requirements of the use of the crusher machine. In this article, the experts of Henan Hongxing Mining Machinery which is major in producing the impact crusher and cone crusher will analyze the technical requirements indicators of the impact crusher to help the users to better use the impact crusher to improve the yield and save energy.
Second, the major parts have the following technical requirements. In terms of the spindle of the impact crusher, the spindle of the impact crusher is the main component to withstand the twisting, bending and the compressive stress, which works under a variety of load. The force situation is very complicated. The spindle is required that to have good mechanical properties to ensure that there is sufficient torsional and bending, anti-fatigue resistance ability. Therefore, the spindle must be made of high-hardness steel with good mechanical properties, wide source, low costs and good performance of heat treatment. In order to ensure the long-term and safe operation of the spindle, the spindle should be checked carefully after the finish machining. There should be no quality shortcomings. The heat treatment of the spindle must have the thermal refining in order to further improve the toughness and the mechanical strength of the spindle to extend the surface.
We should basically take into account the economical efficiency of use and processing according to the requirements. For the impact crusher, we should follow the following aspects. First, the limit deviation of the tolerance dimension not noted on the drawing should comply to the provisions of GB 18U4.As the professional manufacturer of complete sets of mining machinery, such as mobile crushers, raymond mill, Henan Hongxing is always doing the best in products and service.
