Straw Crusher

Straw crushers can process a wide range of materials, including various crop straws and biomass raw materials. In terms of processing capacity, the equipment meets the needs of operations ranging from family farms to industrial-scale production.

Operating Mechanism and Pulverization Principle

The operating mechanism of the straw crusher is based on a collaborative crushing mode of "high-speed rotating hammer impact + material collision + screening and grading". Material is fed evenly and at an appropriate rate into the pulverizing chamber through the inlet. Inside the chamber, high-speed rotating hammers subject the material to intense striking, tearing, and rubbing actions. Driven by centrifugal force, the material is thrown against a toothed plate for further breakage, while particles also collide with one another at high speeds. The pulverized material passes through a screen and is discharged by a fan. The entire process achieves the efficient transformation of long straw into uniform, fine powder.

Coordination Between the Pulverization Process and the Production Line

Straw crushers play a core role in the resource utilization of straw. In an organic fertilizer production line, the machine receives collected straw at the intake stage and shreds it into fine particles; this processing ensures the straw makes fuller contact with microorganisms, thereby accelerating the fermentation process. The shredded material is then transported to a mixing unit, where it is blended with ingredients such as animal manure and microbial inoculants. The shredder integrates seamlessly with equipment such as belt conveyors, quantitative feeders, windrow turners, and screening machines to form a complete straw-based organic fertilizer production line.
