Types of pev jaw crusher are available: assembled frame and welded frame. Pev series jaw crusher is usually used as primary or secondary crusher in quarry production lines. Pev jaw crusher, equipped with the most advanced crushing technology, is the top choice of crushing multi-hard, corrosive materials. Compared with the traditional secondary jaw crushers, which cannot provide bulk production and wear resistance at crushing stones for constructions of highways, railways and airport runways, which mostly are hard rocks like basalt at the size of 3-7cm, pev jaw crusher has unparalleled superiority on service life, maintenance rate, failure rate and lower cost of supporting facilities like cone crusher shaping machine.
