The Jaw Crusher South Africa Sale 's ore outlet can be adjusted, and different ore outlets have different processing capabilities. Therefore, when comparing the processing capacity, it should be determined that the size of the discharge outlet is the same. For example, the C100 type jaw crusher of Nordberg Company has a processing capacity of 265t / h when the closed-side discharge opening is set to 125mm (C, S, S), and the corresponding domestic PE750X1060 type jaw crusher; The processing capacity is 195t / h, about 25% lower. Therefore, in the 250X300t / h scale sand field production line, the use of C100 type as the primary crushing equipment can meet the requirements of use, while the PE750X1060 type is barely difficult. In the past 20 years, the four-link mechanical design theory for the movement method of jaw crusher has made great progress. For example: the two-way biting angle of the crushing cavity, the large swing angle of the short toggle plate, the reduction of the transmission angle and the eccentricity, etc. The products provided by foreign companies have often adopted these proven and mature design theories to improve product performance and reliability. Domestic manufacturers in China have adopted few mature design theories due to various reasons. Their main products are almost all products shaped before the 1970s. They use wear-resistant materials (such as high manganese steel) and important accessories (such as spherical rollers). Bearings) and other domestic basic parts, the similar products with a service life below the international mature level. In addition, the OEM's processing and assembly technology has changed little over the years, such as the assembly process of bearing holes, bearing seat processing, and the processing and assembly of machine frames.
