Introduction of GS Series Trommel Screen

1. Product Overview

1.1. GS series trommel screen is used in dolomite quarry of magnesium plant to screen out crushed material and sieving by ball press before dolomite enters the rotary kiln. It can also be used for the classification of large and small stones in the quarry, and the separation of soil and stone powder; the separation of sand and stone in the sand and quarry; the separation of lump coal and pulverized coal and coal washing (a component of coal washing machinery) in the coal industry; In the chemical industry and mineral processing industry, it is used to classify large and small lumps and separate powdery substances; product classification in the ceramsite industry.

2. Working principle

2.1. The motor is connected with the roller device through a reducer through a coupling or belt transmission device, and the roller device is driven to rotate around its axis. When the material enters the drum device, due to the inclination and rotation of the drum device, the material on the screen surface is turned and rolled, so that the qualified material (product under the screen) is discharged through the screen on the outer circle of the drum, and the unqualified material (product on the screen) discharge through the end of the drum.

3. Product advantages of GS series trommel screen

3.1. The sieve holes are not easy to be blocked;

3.2. Smooth operation and low noise;

3.3. Simple structure and convenient maintenance;

3.4. The screening cylinder can be closed, which is easy to seal and collect dust;

3.5. The whole machine has high reliability and less one-time investment;

3.6. Special screens are used, with high screening efficiency and long service life;

4. Factors affecting the screening accuracy and efficiency of the trommel screen

4.1. Feeding uniformity: When the feeding is uneven, there will be a phenomenon that one side of the screen surface does not have the material on the other side, which will reduce the utilization rate of the overall screen surface and the output will not meet the requirements. On the other hand, due to uneven feeding, it will be a problem that the material on one side is too thick. Once the thickness of the material is too large, it will affect the screening accuracy and output;

4.2. Feeding amount: When using the trommel screen, if too much material is fed at a time, which exceeds the screening load that the screening machine can withstand, the material will be discharged from the discharge port before it can be screened, resulting in too much fine material Discharging from the coarse material port will greatly reduce the screening efficiency;

4.3. Angle: Generally, the trommel screen has a relatively strict installation inclination angle. The angle between the trommel screen and the ground can be changed according to the needs of users. However, the angle is too large or too small: the angle is too large and the material will quickly pass through the surface of the drum screen, and the material has passed through the mesh surface before being screened, and the screening effect is poor; while the angle is too small will affect the material Moving forward will cause a large amount of feed to accumulate on the mesh surface, which will cause a large load on the mesh surface, reduce the service life of the screen, increase the power required for the trommel, and also affect the screening effect.
