熟料破碎机的设计
摘 要
本毕业设计内容为一种锤式破碎机中的熟料破碎机。其工作原理为：电动机带动转子在破碎腔内高速旋转。物料自上部给料口给入机内，受高速运动的锤的打击、冲击、剪切、研磨作用而碎。在下部，设有板碎物料。破碎机的主要工作部件为带有锤子（又称锤头）的转子。转子由主轴、圆盘、销轴和锤子组成。它具有结构简单，破碎比大，生产效率高等特点，可作干、湿两种形式破碎，破碎机适用于矿山、水泥、煤炭、冶金、建材、公路、燃化等部门对中等硬度及脆性物料进行碎破碎机可根据用户要求蓖条调整蓖条间隙，改变出料粒度，以满足不同用户的不同需求。板 Clinker crusher design
Abstract
The contents of graduates involved in the design for a hammer crusher in the clinker crusher. Its working principle: motor driven rotor broken cavity in the high-speed rotation. Material from the upper mouth to feed into the machine, the high-speed movement of the hammer blow, impact, cut, abrasive and broken. In the box on the bottom, with liner, the materials were broken Hammers hit at high speed collision to the liner, broken secondary impact of materials, making crushing effect desirable, finished from discharging from the mouth .
Clinker crusher parts for the major work with a hammer (also known as the Hammer) the rotor. From the main rotor, disc, composed of a hammer and pin. It is simple in structure, broken than large, high production efficiency, for dry and wet broken in two forms, clinker crusher apply to the mining, cement, coal, metallurgy, building materials, roads, fuel sectors such as the middle of the hardness and brittleness Grinding materials clinker crusher can be added based on user requirements and the adjustment of the Bi Bi of the gap, to change the size expected to meet the different needs of different users.
Key words: clinker crusher； rotor； hammer；scaleboard
