新钢良山铁矿选矿厂老三段2号皮带机尾部是粗碎排矿产品(粒度30-130毫米)的受矿关键部位。运输皮带的支承托辊原是一般的槽形托辊, 支架也是普通的标准固定支架。由于旋回破碎机的破碎产品直接从漏斗给入2号皮带机尾部,高差大,矿块大,矿石对皮带的冲击力就大,造成皮带机尾部受矿部分经常出现:槽形托辊被砸裂,支架被压歪,输送胶带易砸裂的现象,造成维修频繁(平均每月维修1—2次),增加成本,影响生产。为解决上述问题,良山铁矿选矿厂于1985年10月开始对老三段2号受矿皮带机尾部进行改造。将受矿皮带机尾部原6组槽形托辊改用4组橡胶缓冲托
Liangshan iron ore beneficiation plant on the 2nd section of the belt conveyor tail is coarse crushing ore products (grain size 30-130 mm) by the key parts of the ore. The supporting roller of the transport belt was originally a trough roller, and the bracket is also an ordinary standard fixing bracket. As the crusher crusher products directly from the funnel into the tail of No. 2 belt conveyor, large height, large ore, the impact of the ore on the belt is large, resulting in the tail part of the belt conveyor often appear: grooved roller was Cracked, the stent is crooked, easy to crack the tape delivery, resulting in frequent maintenance (an average of 1-2 times a month repair), increase costs, affecting production. In order to solve the above problems, Liangshan Iron Mine beneficiation plant in October 1985 began the second section of Laosan 2 by the transformation of the tail of mine belt conveyor. The mine belt machine will be the end of the original six groups of trough roller instead of 4 sets of rubber buffer care
