The difference between shredder and crusher
1. Working principle
Crusher mainly through extrusion, impact, grinding and other ways to break the material. For example, the jaw crusher uses the reciprocating motion of the moving jaw plate and the static jaw plate to squeeze the material and break it; The cone crusher relies on the impact force and extrusion action generated by the rotating movement of the cone to break the material.
The working principle of the shredder is to drive the tool to tear and cut the material through two relatively rotating tool shafts. The material is gradually torn into smaller pieces under the action of the cutter.
2. Applicable materials
Crusher is suitable for high hardness, large block material, such as ore, rock, concrete block and so on. It can break these hard materials into smaller particles or pieces.
Shredder is more suitable for processing some high flexibility, irregular shape, large volume of materials, such as waste tires, plastic film, wood, metal waste (light and thin) and so on. These materials are often difficult to handle effectively through the crusher.
3, discharge particle size and shape
The discharge particle size of the crusher is relatively uniform and fine, usually reaching a few millimeters or even finer. The shape of the broken material is more regular, mostly cubes or approximately cubes.
The discharge particle size of the shredder is relatively large, and the shape is not too regular, and it is long strip or sheet. The size of the discharge particle depends on the spacing of the tool and the characteristics of the material.
4. Processing capacity
The processing capacity of the crusher is generally large, especially when dealing with hard materials, which can break a large amount of materials per unit time.
The processing capacity of the shredder is relatively small, but the processing effect is better for some special materials.
5. Energy consumption and cost
When the crusher deals with hard materials, due to the need for greater crushing force, energy consumption is usually high, and the purchase and maintenance costs of equipment are relatively high.
Shredder energy consumption is relatively low, equipment costs and maintenance costs are generally lower than the crusher, but in the processing of some materials may take a longer time.
6. Application field
Crusher is widely used in mining, building material production, road construction and other fields, is an important equipment for material crushing in these industries.
Shredder is more used in resource recycling, environmental protection industry, waste materials treatment and other fields, used for various waste for preliminary crushing and capacity reduction treatment, in order to subsequent processing and reuse.
In summary, there are obvious differences between shredders and crushers in the working principle, applicable materials, discharge particle size, processing capacity, energy consumption cost and application fields.
