Compared with PEX jaw crusher, PE jaw crusher is suitable for coarse crushing operation while the latter is suitable for medium and fine crushing operation. betonniere.cn gives you the answer below and explains the difference between the two.

　　Generally speaking, the PE jaw crusher has a larger inlet size and a larger discharge size, for example, the PE600×900 model has an inlet size of 600mm wide and 900mm long, and the feed size is suitable for materials below 500mm, and the discharge size is generally below 160mm; while the PEX jaw crusher has a smaller inlet size and a smaller discharge size, for example, the PEX250×1200 model has a smaller inlet size and a smaller discharge size. The PEX250×1200 model, for example, has an inlet size of 250mm wide and 1200mm long, with a feed size suitable for materials below 200mm and a discharge size generally below 30 to 50 mm.

　　1. The PE jaw crusher has a deeper crushing chamber, strong continuous operation capability and large production capacity. It has a much higher production capacity than the PEX jaw crusher compared to the latter, and at the same time, the motors are larger than the latter and use more electricity because of the load.

　　2、The PEX jaw crusher is more stable, the vibration force is very small, and the foundation weight of the machine and equipment is smaller. the equipment weight of PE jaw crusher is usually several times the weight of PEX jaw crusher equipment, and the foundation of PE jaw crusher needs to be bigger and stronger than that of PEX jaw crusher.

　　3. PEX jaw crusher is easy to start because of the small supporting motor and light load. The PE jaw crusher requires a reduced voltage starter cabinet for starting because of the large motor and heavy load.

　　4、Compared with PE jaw crusher, PEX jaw crusher is more convenient for installation, maintenance and overhaul.

颚式破碎机分为粗碎鄂式破碎机和细碎鄂式破碎机，也就是通常所说的PE系列颚式破碎机和PEX系列颚式破碎机。其中P表示破碎，E是指颚式破碎，相当于指明了产品的特点和结构。而细破中的X就是指细碎。这些常见的很容易被记得牢。例如PYBZ-2233弹簧式圆锥破碎机，P表示破碎，Y是指圆锥，B是指标准型、Z是指重型、22表示的是动锥大端直径为2200mm，33表示的是是指给料口宽度为330mm；又例如PYX-2125旋盘式圆锥破碎机，P与Y同是一样，X是指旋盘式，21表示的是动锥大端直径为2100mm，25表示的是喉口尺寸为25mm。

欧版鄂式破碎机（CJ）（PEW）。欧版颚破在破碎腔部分做了调整，相较于普通鄂破的“半V型破碎腔”，欧版颚破的“V型破碎腔”使得实际进料口宽度与名义进料口宽度相一致，更容易排料，不易发生堵料，不易蹦料，破碎腔也更深且无死区，效率提升。

PYZ圆锥破碎机其中P——破碎机、Y——圆锥、B——型、Z——中间型、D——短头型、数字——动锥底部直径(毫米)。例如PYZ是中间型圆锥破，PYB是型圆锥破，PYD是短头型圆锥破。

pc式属于小型锤破，pcz式属于大型锤破。
