The Introduction of Gold Trommel Screen Machine

The trommel screen is mainly composed of a motor, a reducer, a drum device, a frame, a sealing cover, and a material inlet and outlet.

Drum screen is a special screening equipment developed by our company for metallurgy, chemical industry, mining, power plant, coking plant, building materials, and other industries. It overcomes the screen sticking problem of various vibrating screens when screening wet materials. , Improve the output and reliability of the screening system. It is suitable for screening materials of various properties, as well as wet and easily clogged materials such as coal, coal gangue, coke raw slaked lime, etc., especially for the screening of quartz sand (silica sand).

Drum screen structure:

     Stone trommel screen is composed of five parts: hexagonal drum, frame, funnel, reducer and motor. After the broken stones enter the drum, on the one hand, they are screened with the rotation of the drum, and the materials are screened by the centrifugal force of the drum rotation and the jigging action. On the one hand, the stones with large particle size flow forward along the slope of the drum, and are gradually screened out through the screens of different meshes. After being screened out, the small stones fall into their respective funnels, and then are transported out manually or sent to the finished product pile by gravity. It has the advantages of simple and reliable structure, stable operation, good sealing, no pollution, low noise, fast screen change, fine classification, large sorting ratio, high output, accurate sorting, low failure rate and convenient maintenance, etc., especially suitable for sand Grading use of quarry.

    The trommel screen is fine in workmanship, sturdy and durable. The steel frame is welded with section steel. The funnel has a large volume and is made of steel plates. There are five funnels for discharging materials separately. The mouth of the funnel is connected by a flange, which can feed to both sides or one side, which is convenient for hauling or self-flowing, which improves the output and prevents the blocking of the material from wearing the screen and delaying production.

Principle of trommel screen:

     The roller device is installed obliquely on the frame. The motor is connected with the roller device through the reducer through the coupling, and drives the roller device 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 (under-screen product) is discharged through the discharge port at the bottom of the rear end of the drum, and the unqualified material (screened product) The upper product) is discharged through the discharge port at the end of the drum. Due to the turning and rolling of the material in the drum, the material stuck in the sieve hole can be ejected to prevent the sieve hole from being blocked. The principle and structure of trommel sand sieving machine, trommel screening machine and trommel sieve are almost the same, but there are differences in people's understanding and name of it.

Drum sieve features:

1. The sieve hole is not easy to be blocked.

2. Stable operation and low noise.

3. Simple structure and easy maintenance.

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

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

6. Adopt special screen, high screening efficiency and long service life.

Trommel screen range:

1. In the quarry, it is used for grading large and small stones and separating soil and stone powder.

2. It is used to separate sand and gravel in the sand and gravel field.

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

4. In the chemical industry and mineral processing industry, it is used for grading large and small lumps and separating powdery substances.
