With the development of the sand and gravel industry this year, trommel screen equipment has gradually become indispensable and necessary screening equipment in the sand and gravel industry. Mainly used in mixing plants, road and bridge engineering, construction sites, quarries, and other fields to screen materials. Used in conjunction with other facilities, the screening and filtering effect is good, the screen holes are not easy to be blocked, the operation is stable, the noise is low, the structure is simple, the maintenance is convenient, the screening cylinder can be closed, and the dust collection is easy to seal, the reliability of the whole machine is high, and the one-time investment is relatively few. With high screening efficiency and long service life, it is the most commonly used equipment for screening materials.
Power system, roller system, frame assembly, supporting wheel system, guard assembly, import, and export assembly.
The roller device is installed on the frame obliquely and adopts a non-central shaft structure design. The motor drives the pinion gear to rotate with the large gear of the drum or the chain to mesh with the gear on the drum, the motor drives the chain to drive or the drum is placed on two rollers, and the motor drives the rollers to drive. The drum device rotates under the drive of the driving device. When the material enters the drum device, due to the tilt and rotation of the drum device, the material on the screen surface is turned and rolled, so that qualified materials are discharged through the discharge port at the bottom of the rear end drum. Qualified materials are discharged through the discharge port at the end of the drum. Due to the overturning and rolling of the material in the drum, the material stuck in the screen hole can be ejected to prevent the screen hole from being blocked.
Shaftless trommel screen is mainly used for grading processing of belt-shaped and strong winding materials and is widely used in electric power, mining, metallurgy, building materials, chemical, and other production industries. It is often used for the classification of refractory materials, coal, fertilizers, and rocks in sand fields, as well as the screening of viscous and wet materials such as coal, coke, white ash, and placer gold ore to make the product structure more uniform to meet production needs.
Power system, roller system, frame composition, supporting wheel system, feed inlet assembly.
The roller device is installed on the frame obliquely. The motor is connected with the roller device through a coupling through a reducer and drives the roller device to rotate around its axis. When the material enters the drum device, due to the tilt and rotation of the drum device, the material on the screen surface is turned and rolled, so that the qualified materials are discharged through the discharge port at the bottom of the rear end of the drum, and the unqualified materials are discharged through the discharge port at the end of the drum. discharge. Due to the overturning and rolling of the material in the drum, the material stuck in the screen hole can be ejected to prevent the screen hole from being blocked.
1) In the quarry, it is used for the classification of large and small stones and the separation of soil and stone powder.
2) Used for sand and rock separation in sand and rock yard.
3) The coal industry is used for the separation of lump coal and pulverized coal and coal washing.
4) In the chemical industry and mineral processing industry, it is used to classify large and small lumps and separate powdery materials.
