南山选煤厂是年处理能力300万 t 的大型炼焦煤中心选煤厂,生产的冶炼精煤多以5级、8级为主,每天外运6000 t。在火车提速前,为了保证足吨运输,在不用压平、压实的情况下,每节车皮装煤量都要超过车厢上沿200 mm 左右。但是,2007年上半年,由于铁路列车提速,铁路部门提出了新的要求:一是装车量要低于车厢上沿50 mm 以上;二是压平所装精煤。这种情况下,如果不采取压实、压平
Nanshan Coal Preparation Plant is a large-scale coal-coking coal processing plant with an annual processing capacity of 3 million tons. The smelting coal produced mainly uses Grade 5 and Grade 8, with a daily output of 6,000 t. In the train speed before, in order to ensure the full ton of transport, without flattening, compaction, the amount of coal per car over the car should be more than about 200 mm along the car. However, in the first half of 2007, due to the speeding up of railway trains, the railway authorities put forward new requirements: First, the loading capacity should be lower than 50 mm along the carriage; secondly, the clean coal should be flattened. In this case, if you do not take compaction, flatten
