Degradable extrusion granulator needs maintenance

by:TENGDA     2022-09-28

The maintenance of the reducer of the degradable extrusion granulator is the same as that of the general standard reducer. It is mainly to check the wear and failure of gears, bearings, etc. The gear box should use the lubricating oil specified in the machine manual, and add oil according to the specified oil level. Too little oil will cause poor lubrication and reduce the service life of the parts; too much oil will cause high heat, high energy consumption, and easy deterioration of oil. , also make the lubrication ineffective, resulting in the consequences of damage to the parts.
