The high-pressure roller mill is a high-efficiency and energy-saving grinding device and is widely applied to industries such as metallurgy, ore production and the like. The high-pressure roller mill roller used at present basically comprises a roller sleeve and a roller shaft, wherein the roller sleeve and the roller shaft are in interference fit. Because the roller sleeve is in contact with hard materials for a long time in production, the roller sleeve is easy to wear and needs to be replaced periodically so as to ensure the grinding efficiency of the high-pressure roller mill. Taking Zhangzhuang ore HPGR750/19.5-1500 type high pressure roller mill as an example, the roller is put into production from 2015 and is used for 30 months cumulatively until the surface of the roller tire is abraded seriously, and the service life of the roller tire exceeds the specified service life. In order to ensure the normal operation of the equipment, the movable and fixed rollers need to be replaced in time.

The roll sleeve and the roll shaft of the Zhangzhuang mine HPGR750/19.5-1500 type high-pressure roller mill are assembled in an interference fit mode, the roll sleeve needs to be heated to about 300 ℃, and the assembly is carried out when an inner hole expands to a certain size. Because the temperature of the roller sleeve after being taken out of the furnace is too high, field assembly workers can not directly approach the roller sleeve, and therefore the roller sleeve is inconvenient to directly measure the size of the inner hole by adopting the conventional go gauge.
