9 trommel screen advantages

2019-09-12

The trommel screen is a new type of screening equipment, which mainly consists of motor, reducer, roller unit, frame, sealing cover, inlet, and outlet. The whole body is inclined to the ground plane, and the outside is sealed by a sealing cage to prevent environmental pollution.

Through the variable speed deceleration system, the screening cylinder is rotated at a certain rotation speed, and the material is separated from the top to the bottom through the screening cylinder, the fine material is discharged from the lower part of the front end of the screening cylinder, and the coarse material is discharged from the lower end of the screening cylinder. The rotary trommel screen can be equipped with an automatic tapping device. During the screening process, the relative movement of the flapping device and screening cylinder uninterruptedly cleans the sieve body, so that the screening cylinder is always clean, non-sticky and non-blocking throughout the working process, and does not affect the screening effect.

Applications of trommel screener

1. Grading of sand and stone in the quarry and separation of soil and stone powder

2. Separation of lump coal from pulverized coal in the coal industry, coal screening and coal washing (part of coal washing machinery)

3. Classification and separation of particles and powdery substances in the chemical industry and the mineral processing industry

Trommel screen advantages

1. Wide adaptability of materials

Trommel screens are widely used in various types of material screening, whether it is sand and gravel, slime, soot, and other materials, can be smoothly screened.

2. Simple and diverse feeding method

The inlet of the barrel screen can be designed according to the actual situation on the site. Whether it is a belt, a funnel or other feeding method, it can be smoothly fed without special measures.

3. High screening efficiency

The equipment can be provided with a comb-type cleaning mechanism. During the screening process, the material entering the screening cylinder can be sieved according to the dirtiness and impurities, thereby improving the screening efficiency of the equipment.

4. Large processing capacity

In the same size, the area of the circle is larger than that of other shapes, so the effective area of the screening is large. So that the material can fully contact the screen, and the sieve component per unit time is large. Because of its simple structure, convenient layout, novel, and mature technology, it is easy to enlarge.

5. Low consumption

Small motor power, one-half to one-third of the other sieve types, and the same amount of material is processed and the running time is only one-half of the other sieve type, so the energy consumption is low.

6. Environmental protection

The entire screening cylinder can be sealed with a sealing isolator, which completely removes the phenomenon of dust flying during the screening cycle and avoids pollution to the working environment.

7. Low noise

The entire screening cylinder can be sealed with a sealing isolator, which completely removes the phenomenon of dust flying during the screening cycle and avoids pollution to the working environment.

8. Long service life

The drum screen rotary screen is composed of several annular nets. The total screening area is much larger than the screening area of other sieve types. In addition, the screening efficiency is high and the equipment running time is short, so the service life is long and easy. Less damage and less maintenance.

9. Easy maintenance

The device can be opened and detached, and the upper cover can be disassembled. After disassembling, it does not affect the normal operation of the machine, and the maintenance is very convenient.
