文中分析了磨球机产生噪声的原因,系在加工过程中,钢球之间相互撞击,钢球与回球槽的碰撞;钢球在提升筒中与筒壁、提升 板的撞击等。改进办法是,在M8891磨球机的出球口垫上聚氨酯弹性橡胶,并在进入提升筒处加上阻挡帘,以缓冲球的冲击速度,在生铁提升板外面涂一层聚氨酯弹性橡胶,可使噪声由106.5分贝( A声级)降到101.5分贝。还介绍了聚氨酯弹性橡胶和220型聚醚材料。附图和表各1个。
In this paper, the reasons for the noise generated by the ball mill are analyzed, which are the collisions between the balls, the collision between the ball and the ball return groove during the machining process, the impact between the ball and the cylinder wall and the lifting plate in the lifting cylinder. The improved approach is, M8891 ball mill in the mouth mat urethane elastic rubber, and into the riser at the block with a curtain to buffer the impact of the ball speed, cast iron plate in the outer layer of polyurethane elastic rubber, can make The noise is reduced from 106.5 dB (A level) to 101.5 dB. Also introduced polyurethane elastic rubber and 220 polyether material. 1 for each drawing and table.
