How to maintain the double shaft shredder blades： Daily Operation and Startup/Shutdown Procedures Before Startup: Ensure the cavity is free of foreign objects, check that the blade is securely fastened and well-lubricated, and confirm that the safety protection is in good condition. For new machines, immediately retighten the blade bolts 1 hour after startup. During operation, ensure materials are fed evenly. Avoid overloading. Do not add hard items such as metal. Monitor for unusual noises. Watch the current and output. Stop the operation immediately if you detect any abnormalities. After stopping, thoroughly clean leftover materials using a brush or compressed air to reach corners. Avoid harsh cleaners at all times. Cleaning and Lubrication Cleaning: Clear materials after each shutdown. Deep-clean the blade chamber and the blade every week. Remove adhered substances to prevent corrosion and damage to the blade edge. Lubrication: Once the blade is cleaned, apply anti-rust oil to prevent corrosion. Bearings, which are the rotating supports that reduce friction within the shredder, should be lubricated with lithium-based grease of NLGI 2 grade (the standard classification for grease thickness and hardness) every 100-500 hours. The reducer, a gearbox that slows the motor's speed to increase torque, should be filled with ISO VG 320 gear oil (an industry-standard viscosity grade) every 2000 hours, with oil temperature maintained at 45-80℃. Apply thread locking adhesive (a chemical that secures threaded fasteners) when tightening bolts. This prevents the bolts from loosening due to vibration or use. Blade Inspection, Grinding, and Replacement Daily Inspection: Check that the blade edge gap (the space between cutting edges) is ≤ 2mm and the bolt torque is within standard limits. If the blade edge becomes dull by more than 1.5mm, repair it promptly. Grinding Specifications: Daily: Clear waste materials. Inspect blade damage and bolts. Listen for abnormal sounds. Check lubrication. Weekly: Deep clean. Sharpen dull blades. Check clearance and parallelism. Lubricate key areas. Monthly: Comprehensive inspection for wear, calibrate clearance, replace failed blades, thoroughly lubricate, and change oil (per schedule) New machine or major overhaul: Tighten blades 1 hour after startup. Complete comprehensive inspections and clearance calibration within 72 hours.

Standardized Installation Procedure for Double Axis Shredder Blades： 1. Safety Precautions Turn off the power and lock it before starting. Put on cut-proof gloves and safety glasses. Get the needed tools: adjustable wrenches, thickness gauges, and rubber hammers. Clean the blade rod and nearby areas. 2. Installation Protocol Examine the replacement blades for edge damage. Verify all positioning pins, retaining screws, and shaft threads show no deformation or wear. Position the blades as outlined in the instructions. Clamp the blades firmly onto the shafts and align them with a uniform tooth-and-groove pattern. Tighten screws evenly to the specified torque (usually 80–120 N·m) using a crisscross pattern. Gauge the gap with a thickness gauge: select 0.2–0.3 mm for hard items and 0.1–0.2 mm for soft ones. Ensure the gap remains constant; reset it if it exceeds 0.05 mm. Rotate both rods by hand at least once. The blades must move smoothly and quietly—never stick, scrape, or resist—before proceeding. 3. Operational Validation and Commissioning Run the machine without any load for three minutes at its usual speed. Watch that it stays steady: there should be no shaking, loud rubbing, or odd movements. Next, cut a sample of material under careful watch. Check that the finished size of the pieces meets the rules (for example, D90 must be less than or equal to the target level); only after this test should the machine be approved for normal work. 4. Critical Safety and Performance Notes Never place gloved hands near rotating components—even during manual rotation. Keep electrical power isolated until all fasteners are fully torqued, and you verify final clearance. If the gap is not correct, blades will wear faster, get too hot, cut poorly, or cause jams in the material feed.

Dual shaft shredder blade material is a core component in solid waste treatment and resource recovery systems. It critically affects shredding efficiency, service life, operational reliability, and total cost of ownership. Four principal blade materials are widely adopted in industry today. Selection depends on waste composition, processing intensity, and operational needs. SKD11 is a high-carbon, high-chromium cold-work tool steel. It is the most prevalent choice for general-purpose applications. With a hardness of HRC 58–60 and moderate toughness, it reliably handles medium- to low-hardness materials. These include plastics, rubber, paper, and light composites. SKD11 is cost-effective, and heat treatment and machining protocols are well established. Maintenance requirements are low. This material is suitable for small- to medium-scale recycling under standard duty cycles. H13 is a chromium–molybdenum–vanadium hot-work tool steel. Compared to other hot-work tool steels, H13 offers superior thermal stability, high hardenability, and strong resistance to thermal fatigue and cracking. H13 keeps its strength and hardness even at high temperatures. Its wear resistance and toughness are well balanced due to the higher carbon and vanadium content. H13 is recommended for shredding tough solid waste, like metal waste or waste containing metal. NM550 (HBW 550) is an abrasion-resistant structural steel. It combines high toughness (impact energy: 30–40 J) with exceptional wear resistance (roughly HRC 55). Its microstructure lessens the risk of chipping and edge fracture. This increases robustness when handling impurity-heavy waste, such as construction debris, mixed municipal waste, or contaminated wood. NM550 improves fault tolerance and reduces downtime from foreign objects. It is well-suited for variable or poorly sorted feed. Material selection must be tailored to the feedstock and operational parameters. SKD11 is best for consistent, low-abrasion processing. Use DC53 for high-strength, high-cycle needs. Prefer H13 when thermal stress or metal content is high. Choose NM550 for very variable, impurity-rich waste streams. Matching materials to needs optimizes operations and lowers lifecycle costs.

The double shaft structure allows the material to be torn and sheared in two directions, with fast processing speed and uniform shredding effect, which is suitable for large and hard materials.The blades are generally multi-claw or tooth-shaped, and the blades on the two shafts interlock and work, with strong tearing force, which can easily break metal, plastic, rubber, wood, etc. The shredder blades are mostly made of high-strength alloy steel or special heat-treated materials, with high hardness, and have good toughness, impact resistance, and are not easy to break.

Lichun is the first solar term in the traditional Chinese twenty-four solar terms, marking the beginning of spring. Lichun usually falls on February 4th or 5th each year, symbolizing the end of the cold winter and the revival of all living things. During Lichun, temperatures begin to rise, and sunlight shines through the thin mist onto the earth, welcoming the arrival of spring. Farmers start to get busy, preparing for spring sowing. At this time, trees sprout new buds, and flowers quietly bloom, as if nature itself awakens overnight. There are many interesting folk customs associated with Lichun, such as eating spring pancakes, biting spring, and hitting the spring ox, all of which symbolize wishes for favorable weather and a bountiful harvest throughout the year. Through these activities, people express their hopes and good wishes for the new year. At last，Licheng wishes everyone health and well-being on the Lichun！
