Straw crusher is a mechanical equipment specifically designed for processing agricultural waste such as straw, wheat straw, corn stover, etc. It can crush these long and difficult to process straw materials into small pieces or fine particles for further utilization, such as as as raw materials for animal feed, organic fertilizers, biomass fuels, or for industrial purposes such as papermaking and sheet manufacturing.
The straw crusher usually includes the following main parts:
Feeding device: used to evenly feed straw into the crusher, commonly including screw propellers or feeding rollers.
Crushing device: This is the core part of the crusher, generally including high-speed rotating blades, hammers, or grinding discs, used for cutting and crushing straw.
Sieve: Used to screen crushed materials to ensure that the particle size meets the requirements. Materials that do not meet the particle size requirements will be re crushed.
Discharge outlet: The crushed straw is discharged from the discharge outlet, and some designs may also include an air delivery device to deliver the crushed material to a designated location.
Transmission system: including motor and transmission device, providing power for the crushing device.
Rack and protective device: used to support the entire equipment while protecting the safety of operators.
The working principle of the straw crusher is based on the high-speed rotating crushing device for cutting and crushing straw:
Feeding: Straw is fed into the crusher through the feeding device.
Crushing: High speed rotating blades, hammers, or grinding discs come into contact with straw and crush it into small pieces or particles through cutting, tearing, friction, and other methods.
Screening: The crushed material passes through a sieve, and materials with qualified particle size are discharged from the discharge port. Materials with unqualified particle size are sent back to the crushing device for secondary crushing.
Discharge: Qualified materials that have been screened are discharged from the discharge port and can be directly used for subsequent processing or application.
Efficient crushing: The high-speed rotating crushing device can quickly crush a large amount of straw, improving production efficiency.
Particle size control: By adjusting the aperture of the sieve, the particle size of the crushed material can be controlled to meet different application requirements.
Wide applicability: Suitable for various types of straw, including but not limited to straw, wheat straw, corn straw, etc.
Environmental protection and energy conservation: Converting straw into valuable resources reduces environmental pollution caused by straw burning, while the energy consumption during the crushing process is relatively low.
Sturdy structure: Made of wear-resistant materials and sturdy structural design, it can withstand long-term high-intensity work and extend the service life of the equipment.
