With the continued development of domestic infrastructure and the national economy, China's construction machinery market has become the focus of attention of the international equipment manufacturers, broken machinery industry is no exception,cone crusher the entry of foreign investment, further exacerbating the degree of competition in the market, the domestic crushing machinery enterprises in order to obtain opportunities tide of competition, the most important issue is to improve the quality and technical content of the existing crushing plant as soon as possible to narrow the gap with foreign advanced level, to create their own brands to gain market initiative, the paper crushing machinery at home and abroad. gap at home and abroad broken mechanical status quo.Broken machinery can usually be divided into six categories, in addition to the hammer crusher and roll crusher, gravel pits common crusher compound pendulum jaw crusher, cone crusher,brick making machine impact crusher and The vertical shaft impact crusher (VSI), four categories.A compound pendulum jaw crusher compound pendulum jaw crusher gravel pits of the primary crusher.The following three aspects to analyze the domestic and international product differentiation.(A) products of different specifications compound pendulum jaw crusher to the length and width of the feed inlet calibration specifications of the machine, the domestic manufacturers are basically coarse crushing series of about eight kinds of specifications products manufactured by industry standards.A major international manufacturer's products with more specifications.For example: Nordberg, Metso Group, C, VB, and heavy-duty 3 series total 22 kinds of specifications; Terex Cedar Group's companies have 28 kinds of specifications; love the STALIN g Group Pioneer 15 kinds of specifications.The present lack of large-sized species: 750mmX1060mm above is bounded to the feed inlet.Manufacturers specifications 3-4.11 kinds of specifications, Nordberg C Series specifications 9 9 Cedar Company.The full range of large size, so that the appropriate construction of large gravel pits early broken equipment can choose.(B) the performance of compound pendulum jaw crusher of the main technical parameters of the processing power and the maximum allowable feed size.The same specifications of the compound pendulum jaw crusher design different, the size of its maximum allowable feed is not the same, our reference to the former Soviet Union standards, the width of the feed opening to the fixed gear plate tooth tip (bottom teeth) and the activities of the tooth plate teeth at the end of (tooth tip) distance,Rotary Kiln and many companies on the international to the distance between the fixed tooth plate and activities of the tooth plate calculation, which marked the same specifications of the products compared to domestic products and the products of foreign companies in fact are often small a tooth depth of the distance, the large size of the crusher teeth deep for the 60-100mm, and therefore domestic products allow the feed size is often small 50-80mm.
The port of discharge of the compound pendulum jaw crusher can be adjusted to correspond to different treatment in the different rows of the mine mouth.Therefore, when comparing processing capacity should be determined the same size as the port of discharge.For example, the Nordberg C100 type compound pendulum jaw crusher, set in the entrance to the mine closed side row (C, S, S) is 125mm, the treatment alicey599 capacity of 265t / h, the the PE750X1060 products; processing capacity is 195t / h, about 25% lower.Thus, in the gravel pits 250X300t / h scale production line, using the C100 type as the primary crusher to meet the requirements, the PE750X1060 type reluctance.(C) product design and manufacturing processes for nearly 20 years, the mechanical design theory for the four-link compound pendulum jaw crusher movement has made great progress.For example: the crushing chamber of the bi-directional nip angle,Rotary dryer the short bracket put on a large angle, to reduce the transmission angle and eccentricity, the products of foreign companies often have proven advanced design theory to improve product performance and reliability.China's domestic manufacturers due to various reasons advanced design theory little, before the 1970s, almost all of the 20th century stereotypes of the mainstream products, the use of wear resistant material (such as high manganese steel) and an important component parts (such as aligning roller bearing) and other domestic basic parts, life below the international advanced level of similar products.
