Pre-Shredder GC Series

Pre-Shredder GC Series

GC series pre-shredder is a high-torque waste pretreatment equipment, used in the first stage of the waste treatment process, suitable for pre-shredding municipal solid waste (MSW), bulky waste, C&D waste, etc. The shredder uses the principle of shearing and tearing to realize shredding, which can shred extremely coarse materials forcefully and prevent the accumulation of raw materials.


Large-scale waste treatment applications face many challenges. For example, the large-scale processing requirements put huge pressure on subsequent treatment equipment, and the wide range of changes in electrical load caused by different types and sizes of waste, etc., which will cause huge uncertainties to the entire system. The addition of a pre-shredder to the disposal system helps to reduce and disassemble the material before it is sent to the main shredder, reducing risks and at the same time homogenizing the feed. Pre-shredders are widely used in projects such as car shell shredding and large-scale obsolete waste disposal.

Working Principle

The pre-shredder uses a low speed, high torque double hydraulic motor to drive the cutter rolls directly. It uses the interaction between the cutters and the middle comb plate to shear, tear and pull the material, and is mostly used as the first step in the shredding process of various solid wastes.

Pre-Shredder GC Series

The pre-shredder is installed in front of the main shredder to help reduce and break up the material before it is fed into the main shredder. This helps to extend the life of the main shredder cutters and prevents non-shreddable and flammable materials from entering, while reducing peak power loads and keeping the line running smoothly. The pre-shredder also homogenises the feed and helps to control the feed rate to the main shredder, thereby increasing throughput and reducing unit processing costs.

Features and Advantages

Extended Information

  1. What is the price of this set of equipment?

    The price issue is one of the most concerned issues for users, but the biggest difference between purchasing these industrial equipment and purchasing consumer goods such as automobiles is that the equipment is usually only a part of the entire contract. Other factors that may affect the price include equipment customization, delivery methods, payment terms and installation terms, etc. The final quotation needs to go through detailed commercial negotiations and technical consultations, and is issued after the relevant details are determined. This is why our website cannot state the price of each product like an online mall. But you don’t have to worry at all. We can give satisfactory answers to customers at different stages as soon as possible, whether you want to quickly know the equipment price for early investment research or for planned or ongoing projects. Just contact us through the methods listed on the website, and all your questions will be answered.
  2. How to improve the service life of pre-shredder?

    (1) Use and operate in strict accordance with the use specifications; (2) do a good job of lubricating all parts; (3) Ensure that the material is completely discharged at the end of the operation; (4) keep the inside of the equipment clean and free of foreign objects; (5) as a core component, the tool must be well maintained.
