Proper maintenance can avoid eccentric cone broken copper set of burn

Proper maintenance can avoid eccentric cone broken copper set burn set 2020 - 05 - 28 in the crushing plant, fault occur, this is about to stop the crusher, the implementation of an unplanned maintenance. Once a failure, you need to take some preventive measures, in order to avoid repeated failure occurred. One unexpected outage might be eccentric copper set of burn. In general, there are three conditions that liner burn set: & diams; Crusher binding & diams completely; Lubricating oil overheating & diams; Return oil filter on the copper scrap lead to eccentric copper set of burning set of factors are: & diams; Use not correct lubricating oil & diams; Lubrication system ( Oil pump) Fault & diams; Improper lining cavity shape & diams; The poor quality of strap & diams; Tension side discharging mouth ( CSS） Small & diams; The feeding segregation & diams; Fine powder content in the feed material is too high & diams; Direction of rotation is not correct copper burn when a set of measures have? First, you need to find out the main reason for the failure, in order to make clear what action could be taken to prevent the fault repeatedly. Then, must immediately remove the damage of copper set, for replacement. Some preventive measures should be taken: when the copper set of adhesion on the crusher spindle ( See image below) , must be removed cutting. Be careful not to scratch the spindle when cutting copper sleeve. The next step? Next, must be the main shaft and eccentric inner surface cleaning and polishing. Later, in at least four highly take 90 & deg; Diagonal position of two points, and eccentric inner diameter measuring spindle diameter, as shown in the figure below. These measurements must be submitted to metso technology department, to assess whether it within the tolerance limit. If more than the limit range, should install the new set of brass. On the other hand, can repair Suggestions, or one of the components must be replaced. Installation shall comply with the crusher operating instructions. Back to normal before operation, should be set to run the running-in: according to the following steps to copper & diams; 1 hour running light crusher; ♦ 50% load crusher running 2 hours, but should be run at maximum discharging mouth, to drive the motor rated power of 50% ( Or 60% of the nominal current) ； ♦ Reduce the discharging mouth crusher operation, until you reach 75% of the rated power, continue to run 4 hours; ♦ Reduce the discharging mouth crusher operation, until you reach 100% of the rated current, and run for an hour. ♦ In between the above four steps, check the equipment, to ensure the normal working conditions, and in the process of crushing operation adjusting ring without beating. ♦ Tip: every time change lining board, should check all the crusher sheath, which helps to avoid equipment unplanned downtime. （ Source: metso company)
