Trommel screen maintenance manual
published date: 04-24-2019
During the use process, the trommel screen runs slowly and evenly, with small impact vibration, stable operation and simple installation. It can be placed directly on a flat floor or floor and under the silo. The machine is easy to close and collect dust, has small maintenance, simple maintenance and long service life. Trommel screens are equipment commonly used in refractory materials, coal, river sand classification, and sand block classification. Do a good job of equipment maintenance to keep the drum screen in a good working condition and delay the service life of the equipment.

Trommel screen maintenance
Use the drum screen to do the part of the equipment reducer and support the lubrication of the bearing parts. The grease used in the roller screen bearing part is calcium-based grease, and the lubrication of the reducer part is periodically lubricated with 45# oil. The drum screen should be filled with grease before it leaves the factory. The user determines the lubrication cycle based on the specific operating conditions. The machine body has two lubrication parts, which are on the bearing block at the head and tail.It is strictly forbidden to make adjustments when the equipment is running, so as to avoid dangerous accidents.
 Trommel screen should be maintained by personnel trained in equipment.
 Equipment maintenance and repair must be carried out after parking.
 Equipment management, maintenance personnel should always patrol the operation of the equipment, for example: whether the fasteners are reliable, whether the rotation is flexible or not. The dirt from the equipment blockage mechanism must be cleaned after the shift.
 The machine can be evenly fed after normal operation. Under normal working conditions, the temperature rise of the bearing should not exceed 40 degrees Celsius. The highest temperature rise should not exceed 70 degrees Celsius. When the temperature exceeds the above temperature, stop immediately, and find out the cause and eliminate the fault in time. Before stopping, the feeding should be stopped first, and the motor should be turned off after the material in the drum screen is completely discharged.
 After the drum screen has been running for a period of time, the dust cover must be opened to check whether the screen is damaged. If it is damaged, it needs to be repaired or replaced with a new screen, otherwise it will affect the product quality.

Drum screen common malfunction repair method
When the trommel screen is working, it is generally matched with the crusher and the belt conveyor to complete the work. Drum sander also named trommel screen or rotary screen. It is used for the separation of lump coal and coal powder, and the separation effect directly affects the working efficiency of the crusher. In daily production, the trommel screen will inevitably have various problems, such as: screen cylinder blockage, joint shaft breakage, sieve ring deformation, etc., which seriously affect the stable operation of the system. Therefore, it is very necessary to understand the cause of the malfunction and take corresponding measures. Screen blockage When the moisture of the coal is high (more than 10% water), the fluidity of the coal powder is obviously reduced, and it is easy to adhere and compact on the sieve cylinder, causing the screen…
Coal vibrating screen models
In the process of coal treatment, screening operations are often used to classify the size of the coal for the next industrial production. There are a variety of coal screening machine models, the most common being round vibrating screens, heavy duty linear vibrating screens and trommel screens. The drum screen is a common vibrating screen for coal. It has a wide application range and high-cost performance. It can be used for screening coal. However, the coal industry generally requires large output and high efficiency. Compared with mining circular vibrating screens and heavy-duty linear vibrating screens, the drum screen is not too large for coal, and the output is limited. Circular vibrating screen and linear vibrating screen have special advantages in screening coal and ore materials. The output is large and the efficiency is high, which is especially suitable for use in…

Solution to the clogging of the sieve of the trommel screen
The drum screen is a simple screening device. The trommel screen is easy to close and collect dust, the maintenance is small, the maintenance is simple, and the service life is long. It is a device frequently used in refractory materials, coal, river sand classification, and sandstone classification. The advantage of the trommel screen is that the structure is not complicated so that the device can be quickly operated, and when the trommel has problems, people can easily solve it. But what should I do when the screen of the trommel screen is blocked? The following screen will introduce several ways to solve the phenomenon of blocking the net. The trommel screen sometimes adopts a mechanism added to the fixed frame, and then the mechanism rotates to drive the belt mounted on the belt to continuously smear the surface of…
