What Kind of Shredding Method Is Generally Used for Municipal Solid Waste?

Shan 2022-03-18

Municipal solid waste is a composite material composed of soil, plastic, waste paper and organic matter. There are currently two mainstream shredding methods: pure tearing or pure shearing. The characteristics of these two types of knives are that they are easy to design and can be processed by wire cutting.

However, in the actual use of municipal solid waste shredding, the single shredding method to deal with composite materials is either low in output or huge tool loss and poor economy, so secondary shredding (pre-shredding + secondary shredding) is often used. . If the material is not so complicated and difficult to shred, it is also possible to use a separate shear shredding for economic reasons.What shredder machine will be used in the shredding method mentioned above? Let us briefly understand below.

Common equipment for shredding municipal solid waste

Shredding is one of the important auxiliary operations in the process of domestic waste treatment. The main purpose is to make large materials smaller and uniform to improve the efficiency and quality of sorting. Municipal solid waste shredding is the shredding of solid waste with the help of various machinery. The main shredding methods are pre-shredder and shear shredder.

Municipal solid waste pre-shredder

Pre-shredder is one of the mainstream shredding equipment with high production efficiency of domestic waste shredding, which can ensure low consumption and reliability, achieve high-power shredding processing capacity and meet high reliability for long-term continuous operation. The equipment is designed with low speed and high torque, and has the characteristics of large shredding force, high output, low noise and good stability. It is often used for pre-shredding of municipal solid waste to facilitate subsequent fine shredding, RDF production, etc.

Municipal Solid Waste Shear Shredder

The municipal solid waste shearing shredder uses the working principle of mutual shearing, tearing and squeezing between knives to process materials. According to different material characteristics and production capacity requirements, the corresponding knives are configured to effectively improve production effectiveness. The equipment adopts the design of "double motor + double reducer", which has the characteristics of large shearing force, low noise and good stability, have good shredding effect for soft and hard materials.

After the introduction, everyone has a certain understanding and understanding of the municipal solid waste shredding method and commonly used equipment. GEP ECOTECH has been advancing on the road of manufacturing and upgrading of municipal solid waste shredding equipment.
