High Efficiency Rotary Trommel Screen Machines For Compost Production Line

Introduction of High Efficiency Rotary Trommel Screen Machines for Compost Production Line:

The High Efficiency Rotary Trommel Screen Machines for Compost Production Line has wide range of sizes and capacities. It is a mechanical screening machine used to separate materials.It consists of a perforated cylindrical drum that is normally elevated at an angle at the feed end, motor, reduction unit, screen frame and sealing cover. It is also known as the trommel screen, rotary screen, trommel vibrating screen, trommel vibrating sieve, drum screen, drum sieve, drum screening machine, revolving screen, cylinder round sifter, cylinder rotary screen, revolving cylindrical sieve, cylinder revolving screen, roller screen, roller sieve etc.

Working Principle of High Efficiency Rotary Trommel Screen Machines for Compost Production Line:

How does the rotary trommel screen machine work? When materials flow towards along the inclined rotating drum, materials jump and roll, the undersized material smaller than the screen apertures passes through the screen, while the oversized material exits at the other end of the drum.

Features of High Efficiency Rotary Trommel Screen Machines for Compost Production Line:

1. Free from pollution- Fully enclosed structure, no dust pollution, improve working conditions for operators as well.
2. Superior design- Simple structure, easy maintenance, steady operation, low energy consumption.
3. Designed to fit your operation- Trommel screen can be customized to meet different capacity and working site.
4. Screen long life span- Screen is made of 16Mn with strong strength, good abrasion resistance and high screening efficiency.
5. Variable application range- Compost,chemical,coal,plastic,recycling,metallurgy,mineral-selecting etc.
6. Less blockage- Automatic cleaning brush on the top of trommel screen to avoid the blockage.

Structure of High Efficiency Rotary Trommel Screen Machines for Compost Production Line:

The rotary screen is mounted obliquely on the frame. The motor is coupled to the drum unit via coupling and reducer to drive the drum unit to rotate about its axis. After the material enters the trommel screen, due to the tilting and rotation of the roller device, the material on the sieve surface is turned over and rolled, so that the qualified material (the product under the sieve) is discharged through the discharge port at the bottom of the rear end of the drum, and the unqualified material (upper screen product) is discharged through the discharge port at the end of the drum.
The trommel screen mainly consists of motor,reducer,roller device, frame, sealing cover and inlet & outlet. Due to the turning and rolling of the material in the drum, the material stuck in the screen hole can be ejected to prevent the screen hole from being clogged.

Technical Parameters of High Efficiency Rotary Trommel Screen Machines for Compost Production Line:

1. driving device 2. coarse material discharge opening 3. seal cover

4. drum body 5. undersize material discharge opening 6. retaining plate

7. feed inlet 8. bracket

Application of High Efficiency Rotary Trommel Screen Machines for Compost Production Line:

The trommel screens are used by the municipal waste industry in the screening process to classify sizes of solid waste. It can also be used to improve the recovery of fuel-derived solid waste. Other applications of trommel screens can be seen in the screening process of composts as an enhancement technique. It selects composts of variable size fractions to get rid of contaminants and incomplete composted residues, forming end products with a variety of uses. Besides this, the food industries use trommel screens to sort dry food of different sizes and shapes. The classification process will help to achieve the desired mass or heat transfer rate and avoid under or over-processing. It also screens tiny food such as peas and nuts that are strong enough to resist the rotational force of the drum.
