The GT series drum screen is a specialized screening equipment developed by our company for industries such as power plants, coking plants, building materials, metallurgy, chemical engineering, and mining. It overcomes the problem of screen blockage caused by vibrating screens and linear vibrating screens when screening wet materials, improves the output and reliability of the screening system, and has received unanimous praise from users.

The drum screen is composed of five parts: drum device, frame, funnel, reducer, and electric motor. After the crushed stone enters the drum, it is sieved by the centrifugal force and the effect of the drum's rotation and the use of a jig. Screen out one by one through different mesh screens. Stones of different specifications are sieved out and then funneled into a conveyor belt to be sent to the finished material yard. On the one hand, it is screened as the drum rotates, relying on the centrifugal force and jigging effect of the drum rotation to screen the material. On the one hand, stones with larger particle sizes flow forward along the slope of the drum and are gradually screened out through screens of different mesh sizes. The small stones are sieved out and fall into their respective funnels, and then manually transported or self flowing to the finished product pile.

Working principle of GT series drum screen:

The GT series drum screen uses mechanical methods to drive the drum axis to rotate, and the reducer adjusts the cylinder to rotate at a certain speed. The material enters the cylinder through the feeding port, and under the centrifugal force generated by rotation, the material rolls inside the cylinder and is separated from top to bottom through the grading screen. Due to the different grading sizes of the screen, the material is gradually separated and screened. The qualified particle size materials are sieved and fall into their respective funnels, and then manually transported out or automatically transported to the finished product station by conveyor. Qualified products are discharged through the lower discharge port, with larger particles. Unqualified products are discharged through another discharge port, and the cleaning device inside the cylinder is used to prevent the sieve from being blocked.

The main features of GT series drum screen are:

1. Adopting the rolling conveying principle, the friction coefficient is small, the wear is light, and the sieve holes are not easily blocked.
2. The drum support adopts an integral shaft structure, which runs smoothly, without vibration, and has low noise.
3. The internal drum screen accessories adopt a split design, with a simple structure and quick and convenient replacement and maintenance.
4. The drum body adopts an effective fully sealed structure, which does not raise dust or pollute.
5. Safe and reliable operation, using deceleration transmission, high transmission efficiency, low belt power, low energy consumption, and significant energy-saving effect.
6. We can use different screen materials and mesh sizes according to customer requirements, with high screening efficiency, long service life, and low maintenance costs.
7. Strong adaptability to materials, capable of screening materials with various properties such as viscosity, high humidity, dirt, and impurities;
8. Low investment cost, high output, and high efficiency.
9. The feeding methods can be diversified, including manual and mechanical transmission, which can enable large-scale streamlined operations.

GT series drum screen is suitable for industries:

1. Used for grading stones of different sizes and separating soil and stone powder in the quarry.

2. Separate from sand and gravel in the sand and gravel field.

3. The coal industry is used for the separation of lump coal and coal powder, as well as coal washing (a component of coal washing machinery).

4. In the chemical industry and mineral processing industry, it is used for the classification of large and small block materials and the separation of powdery substances.
