The jaw crusher is the main technical parameters of processing power and the maximum permissible feed size. The same specifications jaw crusher due to different design, its maximum permissible feed size is not the same, my reference to use of the former Soviet Union standards, the width of the feed port to a fixed tooth plate tooth tip (bottom teeth) and the activities of the end of teeth-tooth (tooth tip) from the purpose of calculating the standard, while the number of international enterprises to a fixed tooth plate and calculated the distance between the activities of tooth plate, thus showing the same specifications of products, domestic products and foreign enterprises in fact are often small compared to a tooth deep distance, large-sized breakers teeth deep 60-100mm, and therefore domestic product are often too small to allow the feed size of 50-80mm. Jaw Crusher exclusive mine mouth can be adjusted, corresponding to a different row of mine I have a different processing capabilities. Therefore, more processing power, we should determine the row of the same size as mine mouth.

Jaw crusher design and manufacturing process
Jaw crusher design and manufacturing process: Over the past 20 years, against the jaw crusher of the four-link movement method of mechanical design theory has great progress. For example: a two-way Nie crushing chamber angle, short bracket put on a large angle to reduce the transmission angle and eccentricity and so on, the products offered by foreign companies tend to have validated the use of these advanced design theory to improve product performance and reliability. China’s domestic manufacturers a variety of reasons very little use of advanced design theory, its main products were almost exclusively the 20th century, before the 70’s established products, using wear-resistant materials, (such as high-manganese steel) and the important component parts (such as the self-aligning roller bearing) and other domestic-based pieces, life below the international advanced level of similar products. In addition, OEM processing and assembly process and less on the years there is a change, such as the bearing hole, bearing the processing rack assembly process and the processing and assembly and so on.
