How to Enhance the Durability of Roller Skins in Double Roller Press Granulators
To enhance the durability of roller skins in double roller pess granualtors , a comprehensive approach is required — encompassing material selection, raw material pretreatment, standardized operation, proper adjustment, and routine maintenance. Only through such holistic control can one effectively minimize wear, uneven abrasion, and impact damage, thereby significantly extending the service life of the equipment. First and foremost, it is essential to select high-quality, wear-resistant roller skins; priority should be given to high-chromium alloy skins, which possess high hardness and superior wear resistance, making them suitable for the extrusion granulation of most fertilizers and powdered materials. For materials characterized by high hardness and severe abrasiveness, options such as tungsten carbide hardfacing or alloy thermal spraying can be selected to further boost resistance to both wear and impact, thereby fundamentally enhancing overall durability. Secondly, me...
