trummelfiltrid
Trummelfiltrid, also known as a trommel screen or rotary screen, is a mechanical screening machine used to separate materials, primarily in the mining, quarrying, and recycling industries. The device consists of a perforated cylindrical drum that rotates around a horizontal axis. As the drum rotates, material is fed into the drum and passes through the perforations, with smaller particles passing through and larger particles being retained. The retained material is then discharged from the drum, while the smaller particles fall through the screen and are collected separately. Trummelfiltrid is valued for its simplicity, robustness, and ability to handle large volumes of material. It is particularly useful for separating materials with varying sizes and compositions, making it a versatile tool in material processing and waste management.
