1 给料机支承惰轮的改造 我们石灰石矿的破碎运输生产线是1986年从丹麦史密斯公司成套引进的设备,其裙板喂料机的支承惰轮结构简单,轴2直接穿过滚轮1(如图1)。 我矿是露天凹陷型,泥夹带及裂隙较为发育,而且雨水多。所以进入破碎机的矿石里泥水的含量较大,造成大量泥土及碎石沉积在喂料机输送板下面,有的甚至进入了轴和滚轮的间隙里。对此,虽然定期进行清理, 1 Feeder support idler transformation Our limestone mine crushing transportation line is a complete set introduced from Danish company Smith in 1986. The support idler wheel of the apron feeder has a simple structure. The shaft 2 passes through the roller 1 directly figure 1). I mine is open pit type, mud entrainment and cracks more developed, and more rain. Therefore, the content of mud and water entering the crusher is relatively high, causing a large amount of soil and gravel to deposit under the feeder plate of the feeder, and some even enter the gap between the shaft and the roller. In this regard, although regular clean-up,
