The spiral blades of the double screws compost turning machine are core components that directly contact the material. Their wear resistance directly determines the operating efficiency and service life of the fertilizer making machine. Significant improvement in blade wear resistance requires a combination of four dimensions: material upgrading, surface strengthening technology, structural optimization design, and daily maintenance management, to meet the operational needs of high-abrasive materials in organic fertilizer production.
1. Selecting High Wear-Resistant Base Materials to Improve Wear Resistance from the Source
Abandoning traditional ordinary carbon steel blades, high-hardness wear-resistant steel is selected as the base material. This type of steel possesses the dual advantages of high strength and high wear resistance, effectively resisting the impact and scratching of sand and gravel particles in straw and livestock manure mixtures.
3. Optimizing Blade Structural Design to Reduce Material Wear
Reducing friction and wear between the material and the blades from a structural design perspective can be achieved through two key measures: firstly, designing the blade edges with a rounded transition structure instead of traditional right-angle edges to reduce material jamming and scratching during transportation; secondly, adopting a segmented spiral blade design, allowing for the replacement of only the worn segment when local wear is severe, eliminating the need for complete blade replacement. This reduces maintenance costs and ensures continuous and efficient operation of the equipment through precise replacement.
4. Strengthening Daily Maintenance and Management to Reduce Abnormal Wear
Regular maintenance is a crucial guarantee against premature blade wear. Before operation, check the material for large stones, metal, and other hard foreign objects to prevent hard objects from impacting and causing scratches or deformation of the blades; after operation, promptly clean the sticky material remaining on the blade surface to prevent material clumping from exacerbating friction and wear; regularly check the wear status of the blades, and repair or replace them promptly when the wear exceeds 1/3 of the original thickness to prevent a decrease in overall machine operating efficiency due to local wear.
