Shear shredders are versatile and can handle a wide range of materials, including plastic, rubber, metal, wood, and electronic waste. In recycling facilities, they are commonly used to process scrap metal, reducing it to manageable sizes for further recycling operations. In the plastics industry, shear shredders are employed to break down various plastic products and packaging, facilitating the recycling process and enabling the recovery of valuable materials.
The operation of machine shears involves two primary components the upper blade and the lower blade
. The upper blade (or moving blade) applies a downward force, effectively compressing the material against the lower, stationary blade. When the force exceeds the material's shear strength, it causes the material to fracture along the line of cut. The angle of the blades, the speed of the cut, and the type of material being sheared are crucial factors that influence the quality of the cut and the finish of the edges.
