产品级配可保持恒定，因为磨耗件不直接破碎岩石，物料的金属污染极低，性能可靠、振动小，在增加 产能的同时，最大程度地缩减了设备的检修停工时间。
The gradation can be maintained stable, because the wear parts so not crusher the minerals, the metal contamination of minerals is extremely low, the performance is reliable, the vibration is small. Meanwhile of increasing the capacity.it also maximizes to shorten the shut-down time of equipment main tenance.
