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！

On January 26, the eighth day of the twelfth lunar month, various parts of China welcomed the traditional Laba Festival. From the ancient temples offering porridge and blessings to the city commercial districts' intangible cultural heritage performances, from community civility practices to charitable markets spreading love, bowls of warm Laba porridge connect traditional culture with modern life, bringing a unique vitality to this festival that carries the meaning of praying for blessings and good fortune through innovative expressions. LICHENG wishing that every journey has a destination, and every care reaches its place. May those far away return home soon, sitting around the table with their loved ones, sharing the warmth of porridge; may families who stay together chat leisurely, capturing moments of reunion in the cozy daily life; may every household, amidst the warm atmosphere of the Laba Festival, find peace and joy, and gather strength to welcome the New Year.If you have any needs regarding of slitting knife，doctor blades, please contact us.

A slitting knife is an industrial cutting tool specifically used to cut large sheet materials into narrow strips. Its working principle involves the precision cutting of materials by a high-speed rotating blade and is commonly used for processing materials such as film, paper, metal strips, and plastic film. The cutting method of a slitting knife generally uses rotary cutting, which offers higher precision and efficiency compared to traditional straight knife cutting methods. The working principle of a slitting knife mainly relies on the relative motion between the blade and the material. As the material passes through the blade, the rotating blade quickly makes contact with it, generating strong shearing forces that precisely cut the material to the desired width. To ensure cutting accuracy, slitting knives are usually equipped with high-precision adjustment systems, allowing the blade spacing and angle to be adjusted according to different cutting requirements. In practical applications, slitting knives are widely used in printing, packaging, paper processing, metal strip slitting, and other fields. For example, in paper processing, a slitting knife can cut large sheets of paper into rolls of different widths to meet various production needs. In metal processing, slitting knives are used to cut wide metal strips into narrower strips for subsequent processing. In addition to their efficient and precise cutting capabilities, the design of slitting knives also emphasizes durability and ease of maintenance. With technological advancements, new types of slitting knives have made significant progress in blade materials and coating technologies, and innovative blade structures have further improved cutting performance and service life.
