Trommel Screen - NR Series
The Nesans NR Series Trommel Screens are purpose-built for solid waste recycling and material recovery applications, offering a highly effective solution for separating materials based on size. With their robust design and rotating drum mechanism, the NR Series excels in handling municipal solid waste (MSW), construction & demolition waste, compost, plastic scraps, biomass, and other recyclable streams. The gentle tumbling motion and open-screen design reduce clogging and ensure efficient throughput, even with wet or sticky materials.
Designed for continuous-duty performance, the NR Series features a perforated rotating drum that progressively separates materials as it turns. Fine particles fall through the screening holes while larger or non-recyclable materials are conveyed to the discharge end. This screening process not only improves sorting efficiency but also plays a critical role in reducing landfill volumes and maximizing recovery of valuable materials.
With options for different mesh sizes, modular screening zones, and heavy-duty build quality, the NR Series is highly adaptable to diverse recycling environments. Whether you’re operating a transfer station, composting facility, or materials recovery facility (MRF), the Nesans NR Series Trommel Screen offers unmatched reliability, low maintenance, and operational flexibility—making it an essential tool in any sustainable waste management or recycling operation.

How It Works
The Nesans NR Series Trommel Screens operate using a rotating cylindrical drum fitted with perforated openings sized according to the desired material separation. Material—such as municipal solid waste, construction debris, compost, or recyclable fractions—is fed into the elevated end of the drum. As the drum slowly rotates, internal lifters gently tumble and advance the material forward along its length.
During this motion, finer particles pass through the holes in the drum and are collected below, while oversized or non-recyclable materials continue to travel toward the discharge end for further processing or disposal. The constant rotation and tumbling action ensure effective stratification and minimize screen clogging, even with moist or sticky input materials.
The entire system is mounted on heavy-duty trunnion wheels and powered by a robust drive system, allowing for smooth, stable, and continuous operation. Modular drum segments can be customized with varying hole sizes or screen types to achieve multi-stage separation, enabling the NR Series to handle a wide variety of waste streams with high accuracy and minimal downtime.
