Technical Consulting
- Blade Material Selection — Not sure which steel grade matches your waste type? Our engineers recommend SKD11, D2, H13, 9CrSi or hardfacing based on your specific shredding application.
- Installation & Gap Adjustment — Correct blade gap directly affects output quality and blade life. We provide installation guides and can walk you through the process via video call.
- Worn Blade Analysis — Send us photos of worn or broken blades. We analyze the wear pattern to identify if material, hardness or installation needs adjustment.
- Machine Matching — New shredder or upgrading existing equipment? We help you select the right blade configuration for optimal performance.
