The shredding of big bags and PP raffia can present feeding bridges, long fibers and an irregular output. Before evaluating a different blade, it is necessary to identify the way in which the waste arrives: complete bags, fabric cuts, bales or previously reduced material. Each presentation poses a different job to the cutting system.
Pollution also influences
Used bags may retain traces of the transported product, labels or closure elements. Register your status and apply the installation acceptance criteria. A relatively uniform flow allows tools to be compared more reliably. Mixing batches with different contamination and attributing any variation to the cutting edge makes it difficult to evaluate wear.
Rotor technology and flow control
In its IFAT 2026 communication, Lindner cites big bags and textiles among the materials addressed by the Micromat Series IV multicut rotor. The reference illustrates the importance of adapting the cutting system to the fibrous material. It does not imply that blades from different generations are interchangeable, nor does it substitute validation for the model that works in your plant.
Connect crushing and extrusion
A reduction that produces highly variable fragments can make it difficult to feed later stages. Analyze bulk density, long fraction, and flow stability, in addition to size. If the destination is extrusion, agree with the process manager what characteristics the input requires. The useful quality of the grinding matters more than an isolated production figure.
What to send to study a spare part
Add a sample or description of the fabric, photos of wear, and assembly history to the measurements and reference. Indicate whether post-industrial or used material is processed, and what percentage is recirculated. For a comparative test, keep the waste type and record hours, tons and stops. The result must be evaluated on the cutting assembly and the line.
Frequently asked question
Does a rigid plastic blade always work for raffia?
Geometric compatibility and cutting suitability are different issues. Confirm both with equipment documentation and an application evaluation.
