Trommel screens can be used in a variety of applications such as classification of solid waste and recovery of valuable minerals from raw materials. Trommels come in many designs such as concentric screens, series or parallel arrangement and each component has a few configurations. However depending on the application required, trommels have several advantages and limitations over other screening processes such as vibrating screens, grizzly screens, roller screens, curved screens and gyratory screen separators.

Some of the main governing equations for a trommel screen include the screening rate, screening efficiency and residence time of particles in the screen. These equations could be applied in the rough calculation done in initial phases of a design process. However, design is largely based on heuristics. Therefore, design rules are often used in place of the governing equations in the design of a trommel screen. When designing a trommel screen, the main factors affecting the screening efficiency and production rate are the rotational velocity of the drum, mass flow rate of feed particles, size of the drum, and inclination of trommel screen. Depending on desired application of trommel screen, a balance has to be made between the screening efficiency and production rate.

Municipal and industrial waste
Trommel screens are used by the municipal waste industry in the screening process to classify sizes of solid waste.[4] Besides that, it can also be used to improve the recovery of fuel-derived solid waste. This is done by removing inorganic materials such as moisture and ash from the air-classified light fraction segregated from shredded solid waste, thereby increasing the quality of the product fuel.[5] In addition, trommel screens are used for the treatment of wastewater. For this particular application, solids from the entering flow will settle onto the screen mesh and the drum will rotate once the liquid reaches a certain level. The clean area of the screen is submerged into the liquid while the trapped solids fall onto a conveyor which will be further processed before removal.[6]

Mineral processing
Trommel screens are also used for the grading of raw materials to recover valuable minerals. The screen will segregate minuscule materials which are not in the suitable range of size to be used in the crushing stage. It also helps to get rid of dust particles which will otherwise impair the performance of the subsequent machineries in the downstream processes.

Other applications
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.[8] 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.[9]

Q1: Is your compqny a reliable company?
We are a factory, compared with trading company, we have more advantages as below:
1)competitive price
2)customers can test our machines at anytime.
3)repairing the machine in time.
4)on-time delivery
5)10 years manufacture experience
Q2: What about the delivery?
For dredgers in small size we could ship it in containers. But for large one, we will tranport it in bulk. That is why the dredger structure has to be dismantled. After arriving work site, we will send engineers to install and adjust it.
Julong always has various dredgers, aquatic weed harvesters etc. in stock. Spare parts are available too. Thus the delivery time can be shortened. 
Q3:What is the delivery time?
Under normal circumstances, the delivery time shall be within 50 days after receiving the deposit here. But at the moment we have 12inch and 18inch dredger in stock. The delivery time for them will be asured within 30 days.
Q4: What's the payment method?
We can accept T/T, L/C, WESTERN UNION and so on.
