• Detailed Steps for Installing on Dual Shaft Shredder Blades

  Feb 25, 2026

  Detailed Steps for Installing on Dual Shaft 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.

• Can the dual shaft shredder choose the shredding size?

  Sep 10, 2025

  A dual shaft shredder can indeed control the size of the shredded material. This is mainly achieved by adjusting the following key parameters:   Blade and gap adjustment: Adjust the blades on the shredder, including the number, shape, and arrangement of the blades. Different blade configurations will affect the size and shape of the shredded material. At the same time, the gap between the twin shafts can be adjusted according to the desired fragment size. Smaller gaps typically produce finer pieces, while larger gaps may produce larger pieces.   Shaft speed and rotation: Adjusting the shaft speed of the twin-shaft shredder also affects the size of the shredded material. Higher speeds generally produce finer fragments, while lower speeds may produce larger fragments.   Feeding speed: Controlling the feeding speed of the raw material can also influence the size of the shredded material. A faster feeding speed may result in insufficient shredding and larger fragments, while a slower feeding speed can lead to more precise shredding, producing smaller fragments.   It is important to note that adjusting a twin shaft shredder to produce specific sizes and shapes of fragments requires some experience and testing. Gradually adjusting the parameters and regularly inspecting and maintaining the machine can ensure that the shredder remains in good condition and produces the desired fragment size.   Additionally, it is also crucial to select a twin shaft shredder model and specification suitable for the material characteristics and required output size. For example, considerations should include the material's hardness, moisture content, and output size requirements to choose the appropriate shredder model and power.

• How two shaft shredder has brought about profound changes in the field of material shredding and crushing

  Oct 20, 2022

  As efficient and environmentally friendly crushing equipment, the design concept and technological innovation of the two-shaft shredder demonstrate a profound understanding of the material crushing field. Compared with traditional crushing equipment, the two-shaft shredder has achieved significant improvements in crushing efficiency, particle size, energy consumption, and other aspects. Firstly, the two shaft shredder employs advanced shredding and crushing principles and structural designs, resulting in more uniform materials and effective shearing forces during the shredding and crushing process. This design not only enhances shredding and crushing efficiency but also ensures a more uniform particle size of the crushed materials, meeting the requirements of various industries for material particle size. Secondly, the twin shaft shredder also has a significant advantage in terms of energy consumption. By optimizing the design of the shredding and crushing tools and selecting suitable materials, the two-shaft shredder can reduce energy loss and improve energy utilization during the crushing process. The dual shaft shredder from ACLSHREDDER not only reduces production costs but also meets current environmental protection requirements for energy conservation and emission reduction. Additionally, the two-shaft shredder also prioritizes environmental protection and sustainable development. During the crushing process, the two-shaft shredder utilizes advanced technologies for dust removal and noise reduction, effectively reducing dust and noise emissions and minimizing environmental pollution. Meanwhile, the two-shaft shredder can also recycle waste, converting it into valuable renewable resources and making positive contributions to environmental protection. The emergence of the two-shaft shredder has not only promoted technological progress in the field of material crushing but also had a profound impact on the development of related industries. In the process of waste treatment and resource recycling in sectors such as plastics, rubber, and wood, two-shaft shredders are playing an increasingly important role. Its efficient and environmentally friendly crushing capacity enables these industries to achieve resource reuse better and reduce environmental pollution, promoting the sustainable development of the industry.

• How to dispose of bulky waste

  Jun 30, 2020

  Bulky waste refers to discarded items that weigh more than 5 kilograms, have a volume greater than 0.2 cubic meters, or exceed a length of 1 meter, and require disassembly before reuse or processing due to their overall integrity. Definition of bulky waste: It generally includes old sofas, mattresses, furniture, garden waste, industrial pallets, renovation debris, and other large solid wastes that are difficult to collect, transport, and recycle.     ACLMEC has launched a dedicated crusher for bulky waste, providing the market with dual shaft shredder bulky waste processing systems and coarse crusher bulky waste processing systems. The feeding methods can be selected from grab feeding, chain plate feeding, or full truck tipping; the discharge can be equipped with a magnetic separator and can connect to storage bins, compactors, or regular trucks.     ACLMEC has focused on researching and solving several major issues in bulky waste crushing: the problem of material sticking, crushing force issues, and dust leakage problems. The new cutter structure, variable-speed tearing program, and spindle surface treatment solve the material sticking issue, eliminating chronic problems in bulky waste crushing systems. The entire system is highly enclosed, and the sheet metal of the crusher and conveyor is designed with overlapping, fitting, and sealing techniques, combined with a pulse dust removal system.
