details

description

high mn steel ball mill liner plate in general refers to a kind of casting steel with the mn content at 1115the carbon content at 0.91.5 mostly higher than 1.0. under low impact load can achieve hb300400 high impact load can achieve hb500800.different impact load the surface hardening layer depth can be up to 1020 mm. high hardness of hardening layer can resist the wear of grinding media. under the condition of strong impact abrasive wear high manganese steel has excellent anti-wear performance.

processing technique

intermediate frequency furnace smelting high-quality steel scrap and chrome and mo alloy etc.

constant temperature casting process ensuring the quality no solid nonmetallic impurity no pore etc.

automatic temperature tempering heat treatment process changing the internal organizational structure further improving the mechanical properties.

after the pre- furnace test semi-finished products and finished products inspection was done by advanced spectrometer and durometer imported from germany.

instruction for use

1.it is forbidden to grinding the empty machine otherwise it will make grinding media strike the cylinder body violently which will seriously damage the service life of the ball mill liner and increase the wastage of the grinding media.

2.before installing the liner plate the cylinder body should be clean up.

3.when fixing the plate bolts sheet gasket should be carefully matted in case of pulp coming out.

4.before installing the liner should be checked carefully. the back and all around of the liner should be smooth. the sand and the casting flash around the plate hole should be thoroughly removed so that the bolt can be smoothly fixed. the back and all around should be polished accordingly by using grinder to meet the installation requirements.

note any need to adjust the chemical elements or add alloying element it would be agreed with contract.
