What are the characteristics of trommel screen structure

Trommel screen is a new generation of screening equipment. Trommel screen is mainly composed of motor, reducer, drum device, frame, sealing cover, inlet and outlet. The whole is tilted from the ground plane, and the outside is sealed with a sealed isolation cover to prevent environmental pollution. Through the speed change and reduction system, the sieve cylinder rotates at a certain speed, and the material is separated from top to bottom through the sieve cylinder. Fine material is discharged from the lower end of the sieve cylinder, while coarse material is discharged from the lower end of the sieve cylinder.

Working principle of trommel screen:
The screen device is mounted on the rack at an inclined Angle. The motor is connected with the drum unit through a coupling through the reducer, and drives the drum unit to rotate around its axis. When the material enters the drum unit, due to the tilt and rotation of the drum unit, the material on the screen turns and rolls, so that the qualified material (the product under the sieve) is discharged through the discharge port at the bottom of the back end of the drum, while the unqualified material (the product on the sieve) is discharged through the discharge port at the end of the drum. Due to the turnover and rolling of the material in the drum, so that the material stuck in the screen hole can be ejected, to prevent the screen hole blocked. The principle structure of drum sieve sand machine, drum sieve and trommel screen are almost the same, which is the difference in people's understanding and naming.
Application of trommel screen:
1. In the stone yard, it is used for grading large and small stones and separating soil and stone powder.
2. In the sand yard, it is used for separating the sand from the stone.
3. In the coal industry, it is used for lump coal and pulverized coal separation, coal screening and coal washing (part of coal washing machinery).
4. In chemical industry and mineral processing industry, it is used for grading large and small lumps and separating powdery substances.
Characteristics and advantages of trommel screen:
1. Wide adaptability of materials. Trommel screen is widely used in the screening of all kinds of materials, whether it is inferior coal, slime, soot and other kinds of materials, it is carried out smoothly.
2. Simple and diverse feeding methods. The feeding port of our trommel screen can be designed according to the actual situation. No matter the belt, funnel or other feeding methods, no special measures need to be taken, the feeding can be smooth.
3, High screening efficiency. The equipment can be equipped with comb cleaning mechanism, in the screening process, no matter how dirty and miscellaneous materials into the screening cylinder can be screened, so as to improve the screening efficiency of the equipment.
4, large screen capacity. With the same size, the circle area than other types of area are larger, so the effective screen area is large, so that the material can fully contact the screen, so that the screen per unit time component is large. Because of its simple structure, convenient layout, novel and mature technology, it is easy to be large.
5. Small energy consumption. Trommel screen motor has a small power, which is one half to one third of that of other screen types. It can only handle the same amount of materials and operate for one half of other screen types, so the energy consumption is low.
6. Good working environment. The whole sieve cylinder can be sealed with a sealed isolation cover, which completely eliminates dust flying and other phenomena during the sieve cycle and avoids pollution to the working environment.
7. Low equipment noise. In the operation of trommel screen, because of the low rotary speed, and there is a sealed enclosure for isolation from the outside world, so that the noise can not be transferred to the outside, so as to reduce the noise equipment.
8. Long service life and small maintenance. Trommel screen is composed of a number of circular mesh, the total screening area is far greater than that of other screen type, coupled with high screening efficiency, short equipment operation time, so long service life, less wear parts, small maintenance.
9. Convenient maintenance. The sealing isolation cover of the equipment can be taken apart, which will not affect the normal operation of the machine and make the maintenance very convenient.
