A trommel is a piece of equipment used in the processing of municipal solid waste. It consists of a cylindrical drum that rotates, separating materials by size as they pass through the drum. The trommel is often used to sort out larger materials such as sticks, rocks, and larger pieces of waste, which can then be further processed or disposed of separately. It can also be used to separate recyclable materials such as plastics and metals.
Trommels can come in a variety of sizes and designs depending on the intended use and the specific waste being processed. Some are stationary, while others are mobile, mounted on a trailer for easy transport. They are typically powered by electricity or diesel engines.
Trommels are a common component in many waste processing facilities, including recycling plants and landfills. They can be used to improve efficiency and reduce waste volumes, as well as help recover valuable materials for recycling. They are also used in composting operations, where they help to separate out larger materials that may be difficult to break down in the composting process.
