Top Quality China ISO Certified Inclined Coal Roller Screen for Crushing | Reliable Suppliers & Factory
Roller Screen Features
- The shaft sieve is driven by a single shaft of roller motor, which is convenient for maintenance.
- The screen shaft at the feeding end is installed at an inclined position, which can quickly separate the materials and have a high screening effect.
- The sieve pieces on the two sieve shafts intersect, reducing the dead angle formed by adjacent sieve shafts and avoiding jammed sieve.
- There is a bypass, equipped with electric actuator, manually operated reversing mechanism, do not need to screen, directly through the side of the road, to facilitate equipment maintenance and cleaning.
- The bypass reversing plate adopts the structure of bar and sand, when the material falls to the reversing plate part of the particles are screened first, which favorably improves the screening efficiency.
- Both sides of the box layout design movable insert structure, when the need to replace the maintenance of screen shafts, sieve sheet, anti-corrosion liner is very convenient.
- It is equipped with coal plugging alarm and electrical control safety protection to avoid equipment damage caused by abnormal operation.

Application
Precautions During Operation
⚠️
Important Safety Notice: The working environment temperature should be between -25℃ ~ +40℃. The maximum temperature of the reducer is not allowed to exceed +80℃. Ensure there are no flammable or explosive materials nearby.
- The motor should be firmly fixed during operation, without abnormal vibration and noise, and the motor shell is not overheated.
- Hard gear reducer adopts gear oil lubrication, the oil level should be kept in the middle of the sight oil window, the duty personnel should check the oil level every shift, and should replenish the oil in time when it is in short supply to ensure the normal operation of the reducer.
- The reducer should run smoothly, no noise, foot bolts and connecting bolts should be no loose phenomenon, no oil leakage, vibration, overheating phenomenon.
- The sieve shaft rotation should be flexible and smooth, found that the sieve shaft does not turn should stop running, notify the maintenance personnel to check and deal with.
- The equipment should be screened at a high rate, the coal crusher is basically running in the no-load state, the screen sealing performance is good. Open the door every one to two months to clean up viscous deposits, so as not to affect the normal operation of the screen.
- When the equipment is running, the shovel knife is easy to hang under the gun line and other debris, 6-10 months to clean up once. In order to avoid excessive accumulation of debris under the shovel knife affects the service life of the sieve.
- Site lighting is sufficient, communication facilities are intact, the channel is smooth and unobstructed, and keep good fire-fighting facilities.
- Running to monitor and check the operating conditions. For example, the current of the motor, the temperature of the bearing part, as well as the ringing sound, the tightness of the bonding surface, the tightness of the connecting screws and so on.
- After the equipment stops, the duty officer should check that there should be no residue on the screen surface, and should try to remove it if there is.
Common Failures and Handling
| Warning Signs | Reason | Treatment Measure |
|---|---|---|
| Press the start button, the motor will not turn | The button is improperly connected or the control loop is faulty | Press the stop button, report to the monitor, and inform the electrician class to check and deal with it |
| Unpowered power supply | ||
| No operating power supply | ||
| Motor itself damage | ||
| Poor screening performance | The quince-shaped roller piece has a channeling shaft or falls off | Notify maintenance personnel to check and deal with |
| The screen shaft suddenly stops moving during operation | Thermal protection action of the motor | Notify electrical personnel to deal with |
| The nylon pin on the coupling has been cut | Under the condition of ensuring safety, remove the coal accumulation and debris between the sieve shaft, and notify the maintenance personnel to replace the nylon pin | |
| Roller screen output is insufficient | There is too much moisture in the coal | Reduce the output of the coal source equipment, stop the operation of the equipment and check the screen surface |
| The size of the coal is too large | ||
| There is a serious stuck phenomenon between the sieve shafts | ||
| High bearing temperature | Too much or not enough oil | Pay attention to observe the temperature change, if more than 80℃, should immediately stop, report to the monitor, notify the maintenance personnel to check |
| The bearing inner sleeve moves relative to the shaft, the jacket moves relative to the bearing seat | ||
| Bearing failure | ||
| Motor, reducer abnormal vibration, sound or overheating phenomenon | The anchor bolts of the motor and reducer base are loose | Report to the monitor, reduce system output and pay attention to observation, stop immediately in serious cases, and notify the maintenance personnel to check and deal with |
| Overload exercise | ||
| The motor or reducer itself is faulty |
Production and Processing Procedures
Frequently Asked Questions
What is the main advantage of the roller screen's shaft sieve?
The shaft sieve is driven by a single shaft of a roller motor, which makes it highly convenient for maintenance and ensures stable operation.
How does the roller screen prevent jammed sieves?
The sieve pieces on the two sieve shafts intersect, significantly reducing the dead angle formed by adjacent sieve shafts and effectively avoiding material jams.
What should I do if the screen shaft stops moving suddenly?
You should check if the thermal protection of the motor has activated or if the nylon pin on the coupling has been cut. Notify electrical or maintenance personnel immediately to address the issue.
How often should the shovel knife and screen be cleaned?
Viscous deposits inside the screen should be cleaned every 1 to 2 months. The shovel knife should be cleaned every 6 to 10 months to avoid excessive accumulation of debris which can affect the sieve's service life.
What is the maximum allowable working temperature for the reducer?
The working environment temperature should be between -25℃ and +40℃. The maximum temperature of the reducer itself is strictly not allowed to exceed +80℃.
Why might the roller screen output be insufficient?
Insufficient output can be caused by too much moisture in the coal, excessively large coal sizes, or a serious stuck phenomenon between the sieve shafts. Reducing the output of the coal source equipment and checking the screen surface is recommended.
