The new jaw crusher adopts the most advanced crushing technology and manufacturing level in the world. It is the first choice and efficient product for crushing hard and abrasive materials, especially suitable for crushing stone used in engineering buildings such as roads, railways and airport runways. The stone materials used in expressway, railway, airport runway and other projects are mainly hard rocks such as basalt, with specifications of about 3-7 cm or 2-8 cm. The hardness of the crushed materials is relatively high, so the general jaw crushing (jaw crushing) is not only low in output but also easy to wear. Compared with the traditional two-stage jaw crusher, the new jaw crusher shows its incomparable advantages in service life, maintenance rate and failure rate, but compared with cone crusher and stone forming machine, the cost is still at the bottom.
