SatrindTech bag opener shredders are designed for the primary reduction of bulky and resistant materials, with an emphasis on productivity and the ability to handle high-volume waste streams. Unlike grinders, shredders do not aim for controlled particle size but for maximum volume reduction in the shortest possible time: the material is torn, opened, and reduced to manageable sizes for subsequent treatment stages.

The bag opening function is a fundamental feature of this category: low-speed, high-torque blades effectively open waste bags without pulverizing the contents, preserving the integrity of materials for subsequent separation and sorting operations. The range covers power ratings from 22 to 314 kW with working chambers up to 2700×1500 mm, capable of processing up to 60 t/h of municipal solid waste — the reference solution for mechanical-biological treatment (MBT) plants and sorting platforms.

SatrindTech bag opener shredders are primarily used in waste treatment plants that require high productivity in the primary reduction stage, before material separation and sorting.
