总结：减少颚式破碎机噪音污染的有效方法是破碎机的螺旋锥体尺寸要适当，这样工人就能更好地处理。

减少颚式破碎机噪音污染的有效方法是增大破碎机的螺旋锥尺寸，这使得工人加工时可能面临一定的挑战，并且在加工过程中可能会出现一些误差。破碎机的螺旋锥锤齿、水平旋转轴、偏心套和主轴在安装过程中可能存在偏差。破碎机的生产环境相对较差，这可能导致齿轮在齿间晃动，从而增加摩擦。偏心套和水平旋转轴的旋转可能会出现不平衡。颚式破碎机通常被称为破碎机，也被称为虎口。破碎腔由两个颚组成，模仿动物的两种运动以完成物料破碎操作。

SBM'crushers are mainly used as coarse crusher and medium crusher in mining, building materials and infrastructure. According to the width of the feed port, it is divided into three types: large, medium and small. The feed port width is larger than 600MM for large machines. The feed port width is 300-600MM for medium-sized machines. The feed port width is less than 300mm for small-sized machines. Machine, the highest compressive strength of the crushed material is 320Mpa. The jaw crusher is simple in structure, easy to manufacture and reliable in operation. The working part of the jaw crusher is two jaws, one is a fixed jaw (fixed), the vertical (or the upper end is slightly inclined) fixed on the front wall of the body, and the other is the movable jaw (moving), the position Tilting, forming a large and small crushing cavity (working cavity) with the fixed jaw. The movable jaws periodically reciprocate against the fixed jaws, sometimes separated and sometimes close. When separated, the material enters the crushing chamber, and the finished product is discharged from the lower portion; when it is close, the material between the two jaws is crushed by bending, bending and splitting.
