Waste trommel is used by the municipal solid waste (or MSW in short) industry in the screening process to classify sizes of solid waste. Waste trommel produced by Deya Machinery for heavy duty applications and designed to provide years of trouble-free separation. Materials are fed into the drum and are lifted up by the rotation and aerated as it falls back down. In some waste trommels, breaking blades are installed inside the drum for opening plastic bags, it is typically used to release materials retained in bags such as household waste which has not been shredded before screening. After the bags breaking, it will be good for further screening by waste trommel.

Synonyms: waste trommel, waste trommel screen, MSW trommel, municipal solid waste trommel


Sieve is a kind of well-distributed holes or grids which is produced by wear-resistant and corrosion-resistant materials, it has screening effect on garbage of different particle sizes. Typical type of sieve is made by perforated plate with modular interchangeable screen sections per customer requirements.

Types of Waste trommel

-According to the type of sieve, it includes woven type and perforated plate type
-According to the breaking knife, it includes breaking knife type and non breaking knife type
