目前,有许多矿山在电子皮带秤的使用中发生故障较多,其主要原因之一就是电磁计数器工作不正常,易坏。因为电子皮带秤在出厂时,其计数器标定为每跳一个字,即计数器每显示一个数,代表矿量为1公斤。但实际磨机的矿石处理量较大(如10吨/时),若按计数器的原标定量考虑,计数器在1小时内要跳字1万次。如此高的计数频率,对一个机械 At present, many mines in the electronic belt scale in the use of more failures, one of the main reasons is the electromagnetic counter is not working properly, easily broken. Because the electronic belt scale at the factory, its counter is calibrated to a word per hop, that is, each counter shows a number, representing the mine volume of 1 kg. However, the actual mill ore handling capacity larger (such as 10 tons / hour), if the original counter to consider the counter, the counter within 1 hour to jump word 10000 times. So high counting frequency, to a machine
